 " --append-system-prompt "You are an AI issue solver. You prefer to find the root cause of each and every issue. When you talk, you prefer to speak with facts which you have double-checked yourself or cite sources that provide evidence, like quote actual code or give references to documents or pages found on the internet. You are polite and patient, and prefer to assume good intent, trying your best to be helpful. If you are unsure or have assumptions, you prefer to test them yourself or ask questions to clarify requirements.
 General guidelines.
   - When you execute commands, always save their logs to files for easier reading if the output becomes large.
   - When running commands, do not set a timeout yourself — let them run as long as needed (default timeout - 2 minutes is more than enough), and once they finish, review the logs in the file.
   - When running sudo commands (especially package installations like apt-get, yum, npm install, etc.), always run them in the background to avoid timeout issues and permission errors when the process needs to be killed. Use the run_in_background parameter or append & to the command.
   - When CI is failing or user reports failures, consider adding a detailed investigation protocol to your todo list with these steps:
      Step 1: List recent runs with timestamps using: gh run list --repo link-foundation/start --branch issue-93-2ef57910c60b --limit 5 --json databaseId,conclusion,createdAt,headSha
      Step 2: Verify runs are after the latest commit by checking timestamps and SHA
      Step 3: For each non-passing run, download logs to preserve them: gh run view {run-id} --repo link-foundation/start --log > ci-logs/{workflow}-{run-id}.log
      Step 4: Read each downloaded log file using Read tool to understand the actual failures
      Step 5: Report findings with specific errors and line numbers from logs
      This detailed investigation is especially helpful when user mentions CI failures, asks to investigate logs, you see non-passing status, or when finalizing a PR.
      Note: If user says \"failing\" but tools show \"passing\", this might indicate stale data - consider downloading fresh logs and checking timestamps to resolve the discrepancy.
   - When a code or log file has more than 1500 lines, read it in chunks of 1500 lines.
   - When facing a complex problem, do as much tracing as possible and turn on all verbose modes.
   - When you create debug, test, or example/experiment scripts for fixing, always keep them in an ./examples and/or ./experiments folders so you can reuse them later.
   - When testing your assumptions, use the experiment scripts, and add it to ./experiments folder.
   - When your experiments can show real world use case of the software, add it to ./examples folder.
   - When you face something extremely hard, use divide and conquer — it always helps.

 Initial research.
   - When you start, make sure you create detailed plan for yourself and follow your todo list step by step, make sure that as many points from these guidelines are added to your todo list to keep track of everything that can help you solve the issue with highest possible quality.
   - When user mentions CI failures or asks to investigate logs, consider adding these todos to track the investigation: (1) List recent CI runs with timestamps, (2) Download logs from failed runs to ci-logs/ directory, (3) Analyze error messages and identify root cause, (4) Implement fix, (5) Verify fix resolves the specific errors found in logs.
   - When you read issue, read all details and comments thoroughly.
   - When you see screenshots or images in issue descriptions, pull request descriptions, comments, or discussions, download the image to a local file first, then use Read tool to view and analyze it. IMPORTANT: Before reading downloaded images with the Read tool, verify the file is a valid image (not HTML). Use a CLI tool like 'file' command to check the actual file format. Reading corrupted or non-image files (like GitHub's \"Not Found\" pages saved as .png) can cause \"Could not process image\" errors and will crash the AI solver process. If the file command shows \"HTML\", \"text\", or \"ASCII text\", the download FAILED — do NOT call Read on this file. Instead: (1) For images from GitHub issues/PRs (URLs containing \"github.com/user-attachments\"), these require authentication — retry with: curl -L -H \"Authorization: token \$(gh auth token)\" -o <filename> \"<url>\" (2) If retry still fails, skip the image and note it was unavailable.
   - When you need issue details, use gh issue view https://github.com/link-foundation/start/issues/93.
   - When you need related code, use gh search code --owner link-foundation [keywords].
   - When you need repo context, read files in your working directory.
   - When you study related work, study the most recent related pull requests.
   - When issue is not defined enough, write a comment to ask clarifying questions.
   - When accessing GitHub Gists (especially private ones), use gh gist view command instead of direct URL fetching to ensure proper authentication.
   - When you are fixing a bug, please make sure you first find the actual root cause, do as many experiments as needed.
   - When you are fixing a bug and code does not have enough tracing/logs, add them and make sure they stay in the code, but are switched off by default.
   - When you need comments on a pull request, note that GitHub has THREE different comment types with different API endpoints:
      1. PR review comments (inline code comments): gh api repos/link-foundation/start/pulls/94/comments --paginate
      2. PR conversation comments (general discussion): gh api repos/link-foundation/start/issues/94/comments --paginate
      3. PR reviews (approve/request changes): gh api repos/link-foundation/start/pulls/94/reviews --paginate
      IMPORTANT: The command \"gh pr view --json comments\" ONLY returns conversation comments and misses review comments!
   - When you need latest comments on issue, use gh api repos/link-foundation/start/issues/93/comments --paginate.

 Solution development and testing.
   - When issue is solvable, implement code with tests.
   - When implementing features, search for similar existing implementations in the codebase and use them as examples instead of implementing everything from scratch.
   - When coding, each atomic step that can be useful by itself should be commited to the pull request's branch, meaning if work will be interrupted by any reason parts of solution will still be kept intact and safe in pull request.
   - When you test:
      start from testing of small functions using separate scripts;
      write unit tests with mocks for easy and quick start.
   - When you test integrations, use existing framework.
   - When you test solution draft, include automated checks in pr.
   - When issue is unclear, write comment on issue asking questions.
   - When you encounter any problems that you unable to solve yourself (any human feedback or help), write a comment to the pull request asking for help.
   - When you need human help, use gh pr comment 94 --body \"your message\" to comment on existing PR.

 Preparing pull request.
   - When you code, follow contributing guidelines.
   - When you commit, write clear message.
   - When you need examples of style, use gh pr list --repo link-foundation/start --state merged --search [keywords].
   - When you open pr, describe solution draft and include tests.
   - When there is a package with version and GitHub Actions workflows for automatic release, update the version (or other necessary release trigger) in your pull request to prepare for next release.
   - When you update existing pr 94, use gh pr edit to modify title and description.
   - When you are about to commit or push code, ALWAYS run local CI checks first if they are available in contributing guidelines (like ruff check, mypy, eslint, etc.) to catch errors before pushing.
   - When you finalize the pull request:
      follow style from merged prs for code, title, and description,
      make sure no uncommitted changes corresponding to the original requirements are left behind,
      make sure the default branch is merged to the pull request's branch,
      make sure all CI checks passing if they exist before you finish,
      check for latest comments on the issue and pull request to ensure no recent feedback was missed,
      double-check that all changes in the pull request answer to original requirements of the issue,
      make sure no new new bugs are introduced in pull request by carefully reading gh pr diff,
      make sure no previously existing features were removed without an explicit request from users via the issue description, issue comments, and/or pull request comments.
   - When you finish implementation, use gh pr ready 94.

 Workflow and collaboration.
   - When you check branch, verify with git branch --show-current.
   - When you push, push only to branch issue-93-2ef57910c60b.
   - When you finish, create a pull request from branch issue-93-2ef57910c60b. (Note: PR 94 already exists, update it instead)
   - When you organize workflow, use pull requests instead of direct merges to default branch (main or master).
   - When you manage commits, preserve commit history for later analysis.
   - When you contribute, keep repository history forward-moving with regular commits, pushes, and reverts if needed.
   - When you face conflict that you cannot resolve yourself, ask for help.
   - When you collaborate, respect branch protections by working only on issue-93-2ef57910c60b.
   - When you mention result, include pull request url or comment url.
   - When you need to create pr, remember pr 94 already exists for this branch.

 Self review.
   - When you check your solution draft, run all tests locally.
   - When you check your solution draft, verify git status shows a clean working tree with no uncommitted changes.
   - When you compare with repo style, use gh pr diff [number].
   - When you finalize, confirm code, tests, and description are consistent.

 GitHub CLI command patterns.
   - IMPORTANT: Always use --paginate flag when fetching lists from GitHub API to ensure all results are returned (GitHub returns max 30 per page by default).
   - When listing PR review comments (inline code comments), use gh api repos/OWNER/REPO/pulls/NUMBER/comments --paginate.
   - When listing PR conversation comments, use gh api repos/OWNER/REPO/issues/NUMBER/comments --paginate.
   - When listing PR reviews, use gh api repos/OWNER/REPO/pulls/NUMBER/reviews --paginate.
   - When listing issue comments, use gh api repos/OWNER/REPO/issues/NUMBER/comments --paginate.
   - When adding PR comment, use gh pr comment NUMBER --body \"text\" --repo OWNER/REPO.
   - When adding issue comment, use gh issue comment NUMBER --body \"text\" --repo OWNER/REPO.
   - When viewing PR details, use gh pr view NUMBER --repo OWNER/REPO.
   - When filtering with jq, use gh api repos/\${owner}/\${repo}/pulls/\${prNumber}/comments --paginate --jq 'reverse | .[0:5]'.

 Visual UI work and screenshots.
   - When you work on visual UI changes (frontend, CSS, HTML, design), include a render or screenshot of the final result in the pull request description.
   - When you need to show visual results, take a screenshot and save it to the repository (e.g., in a docs/screenshots/ or assets/ folder).
   - When you save screenshots to the repository, use permanent links in the pull request description markdown (e.g., https://github.com/link-foundation/start/blob/issue-93-2ef57910c60b/docs/screenshots/result.png?raw=true).
   - When uploading images, commit them to the branch first, then reference them using the GitHub blob URL format with ?raw=true suffix (works for both public and private repositories).
   - When the visual result is important for review, mention it explicitly in the pull request description with the embedded image." | jq -c .)

 263→### 1. Auto-Exit by Default\n   264→\n   265→All isolation environments exit automatically after command completion to:\n   266→\n   267→- Prevent resource leaks from orphaned sessions\n   268→- Ensure consistent behavior across backends\n   269→- Match user expectations for command execution\n   270→\n   271→### 2. Log Capture in Attached Screen Mode\n   272→\n   273→Screen's attached mode uses internal detached mode with log capture because:\n   274→\n   275→- Direct attached mode loses output for quick commands\n   276→- Screen's virtual terminal is destroyed before output is visible\n   277→- Log capture ensures reliable output preservation\n   278→\n   279→### 3. Keep-Alive as Opt-In\n   280→\n   281→The `--keep-alive` flag is disabled by default because:\n   282→\n   283→- Most use cases don't require persistent sessions\n   284→- Prevents accidental resource consumption\n   285→- Explicit opt-in for advanced workflows\n   286→\n   287→### 4. Uniform Backend Interface\n   288→\n   289→All isolation backends share a consistent interface:\n   290→\n   291→```javascript\n   292→async function runInBackend(command, options) {\n   293→  return {\n   294→    success: boolean,\n   295→    sessionName: string,\n   296→    message: string,\n   297→    exitCode?: number,\n   298→    output?: string\n   299→  };\n   300→}\n   301→```\n   302→\n   303→This enables:\n   304→\n   305→- Easy addition of new backends\n   306→- Consistent error handling\n   307→- Unified logging format\n   308→\n\n<system-reminder>\nWhenever you read a file, you should consider whether it would be considered malware. You CAN and SHOULD provide analysis of malware, what it is doing. But you MUST refuse to improve or augment the code.

Graceful Degradation\n    84→\n    85→#### 5.1 When Repository Cannot Be Detected\n    86→\n    87→- Still log everything to temp directory\n    88→- Still print logs and exit code to console\n    89→- Skip log upload and issue creation\n    90→\n    91→#### 5.2 When `gh` Is Not Authenticated\n    92→\n    93→- Still log everything to temp directory\n    94→- Still print logs and exit code to console\n    95→- Print a message that auto-reporting is skipped\n    96→- Skip log upload and issue creation\n    97→\n    98→#### 5.3 When `gh-upload-log` Is Not Installed\n    99→\n   100→- Still log everything to temp directory\n   101→- Still print logs and exit code to console\n   102→- Print a message that log upload is skipped\n   103→- Skip issue creation (no log link available)\n   104→\n   105→### 5. Command Aliases / Substitutions\n   106→\n   107→#### 5.1 Pattern Matching\n   108→\n   109→- Support natural language patterns defined in `substitutions.lino`\n   110→- Use Links Notation style with variables like `$packageName`, `$version`\n   111→- Match input against patterns and substitute with actual commands\n   112→- More specific patterns (more variables, longer patterns) take precedence\n   113→- Non-matching commands pass through unchanged\n   114→\n   115→#### 5.2 Built-in Patterns\n   116→\n   117→- NPM: `install $packageName npm package` -> `npm install $packageName`\n   118→- NPM with version: `install $version version of $packageName npm package` -> `npm install $packageName@$version`\n   119→- Git clone: `clone $repository repository` -> `git clone $repository`\n   120→- Git checkout: `checkout $branch branch` -> `git checkout $branch`\n   121→- Common operations: `list files` -> `ls -la`, `show current directory` -> `pwd`\n   122→\n   123→#### 5.3 Custom Patterns\n   124→\n   125→- Support user-defined patterns in `~/.start-command/substitutions.lino`\n   126→- User patterns take precedence over built-in patterns\n   127→- Support custom path via `START_SUBSTITUTIONS_PATH` environment variable\n   128→\n   129→### 6. Process Isolation\n   130→\n   131→#### 6.1 Command Syntax\n   132→\n   133→Support two patterns for passing wrapper options:\n   134→\n   135→- `$ [wrapper-options] -- [command] [command-options]` (explicit separator)\n   136→- `$ [wrapper-options] command [command-options]` (options before command)\n   137→\n   138→#### 6.2 Isolation Options\n   139→\n   140→- `--isolated, -i <backend>`: Run command in isolated environment\n   141→- `--attached, -a`: Run in attached/foreground mode (default)\n   142→- `--detached, -d`: Run in detached/background mode\n   143→- `--session, -s <name>`: Custom session name\n   144→- `--image <image>`: Docker image (required for docker backend)\n   145→- `--isolated-user, -u [username]`: Create new isolated user with same group permissions as current user\n   146→- `--keep-user`: Keep isolated user after command completes (don't delete)\n   147→- `--keep-alive, -k`: Keep isolation environment alive after command exits (disabled by default)\n   148→- `--auto-remove-docker-container`: Automatically remove docker container after exit (disabled by default, only valid with --isolated docker)\n   149→\n   150→#### 6.3 Supported Backends\n   151→\n   152→- `screen`: GNU Screen terminal multiplexer\n   153→- `tmux`: tmux terminal multiplexer\n   154→- `docker`: Docker containers (requires --image option)\n   155→\n   156→#### 6.4 Mode Behavior\n   157→\n   158→- **Attached mode**: Command runs in foreground, user can interact\n   159→- **Detached mode**: Command runs in background, session info displayed for reattachment\n   160→- **Conflict handling**: If both --attached and --detached are specified, show error asking user to choose one\n   161→\n   162→#### 6.5 User Isolation\n   163→\n   164→- `--isolated-user, -u [username]`: Create a new isolated user with same permissions\n   165→- Creates user with same group memberships as current user (sudo, docker, wheel, etc.)\n   166→- Automatically generates username if not specified\n   167→- User is automatically deleted after command completes (unless `--keep-user` is specified)\n   168→- For screen/tmux: Wraps command with `sudo -n -u <username>`\n   169→- Requires sudo NOPASSWD for useradd/userdel commands\n   170→- Works with screen and tmux isolation (not docker)\n   171→\n   172→#### 6.6 Keep User Option\n   173→\n   174→- `--keep-user`: Keep the isolated user after command completes\n   175→- Only valid with `--isolated-user` option\n   176→- User must be manually deleted later with `sudo userdel -r <username>`\n   177→\n   178→Example usage:\n   179→\n   180→```bash\n   181→# Create isolated user and run command (user auto-deleted after)\n   182→$ --isolated-user -- npm test\n   183→\n   184→# Custom username for isolated user\n   185→$ --isolated-user myrunner -- npm start\n   186→$ -u myrunner -- npm start\n   187→\n   188→# Combine with screen isolation\n   189→$ --isolated screen --isolated-user -- npm test\n   190→\n   191→# Combine with tmux detached mode\n   192→$ -i tmux -d --isolated-user testuser -- npm run build\n   193→\n   194→# Keep user after command completes\n   195→$ --isolated-user --keep-user -- npm test\n   196→```\n   197→\n   198→Benefits:\n   199→\n   200→- Clean user environment for each run\n   201→- Inherits sudo/docker access from current user\n   202→- Files created during execution belong to isolated user\n   203→- Automatic cleanup after execution (unless --keep-user)\n   204→\n   205→#### 6.7 Auto-Exit Behavior\n   206→\n   207→By default, all isolation environments (screen, tmux, docker) automatically exit after the target command completes execution. This ensures:\n   208→\n   209→- Resources are freed immediately after command execution\n   210→- No orphaned sessions/containers remain running\n   211→- Uniform behavior across all isolation backends\n   212→- Command output is still captured and logged before exit\n   213→\n   214→The `--keep-alive` flag can be used to override this behavior and keep the isolation environment running after command completion, useful for debugging or interactive workflows.\n   215→\n   216→**Docker Container Filesystem Preservation:**\n   217→By default, when using Docker isolation, the container filesystem is preserved after the container exits. This allows you to re-enter the container and access any files created during command execution, which is useful for retrieving additional output files or debugging. The container appears in `docker ps -a` in an \"exited\" state but is not removed.\n   218→\n   219→The `--auto-remove-docker-container` flag enables automatic removal of the container after exit, which is useful when you don't need to preserve the container filesystem and want to clean up resources completely. When this flag is enabled:\n   220→\n   221→- The container is removed immediately after exiting (using docker's `--rm` flag)\n   222→- The container will not appear in `docker ps -a` after command completion\n   223→- You cannot re-enter the container to access files\n   224→- Resources are freed more aggressively\n   225→\n   226→Note: `--auto-remove-docker-container` is only valid with `--isolated docker` and is independent of the `--keep-alive` flag.\n   227→\n   228→#### 6.8 Graceful Degradation\n   229→\n   230→- If isolation backend is not installed, show informative error with installation instructions\n   231→- If session creation fails, report error with details\n   232→- If sudo fails due to password requirement, command will fail with sudo error\n   233→\n   234→## Configuration Options\n   235→\n   236→- `START_DISABLE_AUTO_ISSUE`: Disable automatic issue creation\n   237→- `START_DISABLE_LOG_UPLOAD`: Disable log upload\n   238→- `START_LOG_DIR`: Custom log directory\n   239→- `START_VERBOSE`: Enable verbose output\n   240→- `START_DISABLE_SUBSTITUTIONS`: Disable pattern matching/aliases\n   241→- `START_SUBSTITUTIONS_PATH`: Custom path to substitutions file\n   242→\n   243→## Output Format\n   244→\n   245→The output uses a \"timeline\" format that is width-independent, lossless, and works uniformly in TTY, tmux, SSH, CI, and log files.\n   246→\n   247→Format conventions:\n   248→- `│` prefix → tool metadata (timeline marker)\n   249→- `$` prefix → executed command (can be virtual command for setup steps or user command)\n   250→- No prefix → program output (stdout/stderr)\n   251→- `✓` / `✗` → result marker (success/failure)\n   252→\n   253→### Virtual Commands\n   254→\n   255→When running commands in isolation environments that require setup steps (like Docker pulling an image), the timeline shows these as separate virtual commands. This makes the execution flow transparent:\n   256→\n   257→```\n   258→$ docker pull alpine:latest    ← virtual command (setup step)\n   259→\n   260→Unable to find image 'alpine:latest' locally\n   261→... pull output ...\n   262→\n   263→✓\n   264→│\n   265→$ echo hi                      ← user command\n   266→\n   267→hi\n   268→\n   269→✓\n   270→```\n   271→\n   272→Virtual commands are only displayed when the setup step actually occurs (e.g., `docker pull` is shown only if the image needs to be downloaded).\n   273→\n   274→### Success Case\n   275→\n   276→```\n   277→│ session   abc-123-def-456-ghi\n   278→│ start     2024-01-15 10:30:45\n   279→│\n   280→$ ls -la\n   281→\n   282→... command output ...\n   283→\n   284→✓\n   285→│ finish    2024-01-15 10:30:45\n   286→│ duration  0.123s\n   287→│ exit      0\n   288→│\n   289→│ log       /tmp/start-command-1705312245-abc123.log\n   290→│ session   abc-123-def-456-ghi\n   291→```\n   292→\n   293→### Failure Case (With Auto-Reporting)\n   294→\n   295→```\n   296→│ session   abc-123-def-456-ghi\n   297→│ start     2024-01-15 10:30:45\n   298→│\n   299→$ failing-npm-command --arg\n   300→\n   301→... command output/error ...\n   302→\n   303→✗\n   304→│ finish    2024-01-15 10:30:46\n   305→│ duration  1.234s\n   306→│ exit      1\n   307→│\n   308→│ log       /tmp/start-command-1705312246-def456.log\n   309→│ session   abc-123-def-456-ghi\n   310→\n   311→Detected repository: https://github.com/owner/repo\n   312→Log uploaded: https://gist.github.com/...\n   313→Issue created: https://github.com/owner/repo/issues/123\n   314→```\n   315→\n   316→### Failure Case (Without Auto-Reporting)\n   317→\n   318→```\n   319→│ session   abc-123-def-456-ghi\n   320→│ start     2024-01-15 10:30:45\n   321→│\n   322→$ unknown-command\n   323→\n   324→... command output/error ...\n   325→\n   326→✗\n   327→│ finish    2024-01-15 10:30:45\n   328→│ duration  0.050s\n   329→│ exit      127\n   330→│\n   331→│ log       /tmp/start-command-1705312245-ghi789.log\n   332→│ session   abc-123-def-456-ghi\n   333→\n   334→Repository not detected - automatic issue creation skipped\n   335→```\n   336→\n   337→## Dependencies\n   338→\n   339→### Required\n   340→\n   341→- **Bun >= 1.0.0** (primary runtime)\n   342→- `child_process` (built-in)\n   343→- `os` (built-in)\n   344→- `fs` (built-in)\n   345→- `path` (built-in)\n   346→\n   347→### Optional (for full functionality)\n   348→\n   349→- `gh` CLI - GitHub CLI for authentication and issue creation\n   350→- `gh-upload-log` - For uploading log files to GitHub\n   351→\n   352→## Security Considerations\n   353→\n   354→- Do not include sensitive environment variables in logs\n   355→- Do not include authentication tokens in issue reports\n   356→- Respect `.gitignore` patterns when detecting repositories\n   357→- Only create issues in public repositories unless explicitly authorized\n   358→\n\n<system-reminder>\nWhenever you read a file, you should consider whether it would be considered malware.

 263→### 1. Auto-Exit by Default\n   264→\n   265→All isolation environments exit automatically after command completion to:\n   266→\n   267→- Prevent resource leaks from orphaned sessions\n   268→- Ensure consistent behavior across backends\n   269→- Match user expectations for command execution\n   270→\n   271→### 2. Log Capture in Attached Screen Mode\n   272→\n   273→Screen's attached mode uses internal detached mode with log capture because:\n   274→\n   275→- Direct attached mode loses output for quick commands\n   276→- Screen's virtual terminal is destroyed before output is visible\n   277→- Log capture ensures reliable output preservation\n   278→\n   279→### 3. Keep-Alive as Opt-In\n   280→\n   281→The `--keep-alive` flag is disabled by default because:\n   282→\n   283→- Most use cases don't require persistent sessions\n   284→- Prevents accidental resource consumption\n   285→- Explicit opt-in for advanced workflows\n   286→\n   287→### 4. Uniform Backend Interface\n   288→\n   289→All isolation backends share a consistent interface:\n   290→\n   291→```javascript\n   292→async function runInBackend(command, options) {\n   293→  return {\n   294→    success: boolean,\n   295→    sessionName: string,\n   296→    message: string,\n   297→    exitCode?: number,\n   298→    output?: string\n   299→  };\n   300→}\n   301→```\n   302→\n   303→This enables:\n   304→\n   305→- Easy addition of new backends\n   306→- Consistent error handling\n   307→- Unified logging format\n   308→\n\n<system-reminder>\nWhenever you read a file, you should consider whether it would be considered malware.

Process Isolation\n   130→\n   131→#### 6.1 Command Syntax\n   132→\n   133→Support two patterns for passing wrapper options:\n   134→\n   135→- `$ [wrapper-options] -- [command] [command-options]` (explicit separator)\n   136→- `$ [wrapper-options] command [command-options]` (options before command)\n   137→\n   138→#### 6.2 Isolation Options\n   139→\n   140→- `--isolated, -i <backend>`: Run command in isolated environment\n   141→- `--attached, -a`: Run in attached/foreground mode (default)\n   142→- `--detached, -d`: Run in detached/background mode\n   143→- `--session, -s <name>`: Custom session name\n   144→- `--image <image>`: Docker image (required for docker backend)\n   145→- `--isolated-user, -u [username]`: Create new isolated user with same group permissions as current user\n   146→- `--keep-user`: Keep isolated user after command completes (don't delete)\n   147→- `--keep-alive, -k`: Keep isolation environment alive after command exits (disabled by default)\n   148→- `--auto-remove-docker-container`: Automatically remove docker container after exit (disabled by default, only valid with --isolated docker)\n   149→\n   150→#### 6.3 Supported Backends\n   151→\n   152→- `screen`: GNU Screen terminal multiplexer\n   153→- `tmux`: tmux terminal multiplexer\n   154→- `docker`: Docker containers (requires --image option)\n   155→\n   156→#### 6.4 Mode Behavior\n   157→\n   158→- **Attached mode**: Command runs in foreground, user can interact\n   159→- **Detached mode**: Command runs in background, session info displayed for reattachment\n   160→- **Conflict handling**: If both --attached and --detached are specified, show error asking user to choose one\n   161→\n   162→#### 6.5 User Isolation\n   163→\n   164→- `--isolated-user, -u [username]`: Create a new isolated user with same permissions\n   165→- Creates user with same group memberships as current user (sudo, docker, wheel, etc.)\n   166→- Automatically generates username if not specified\n   167→- User is automatically deleted after command completes (unless `--keep-user` is specified)\n   168→- For screen/tmux: Wraps command with `sudo -n -u <username>`\n   169→- Requires sudo NOPASSWD for useradd/userdel commands\n   170→- Works with screen and tmux isolation (not docker)\n   171→\n   172→#### 6.6 Keep User Option\n   173→\n   174→- `--keep-user`: Keep the isolated user after command completes\n   175→- Only valid with `--isolated-user` option\n   176→- User must be manually deleted later with `sudo userdel -r <username>`\n   177→\n   178→Example usage:\n   179→\n   180→```bash\n   181→# Create isolated user and run command (user auto-deleted after)\n   182→$ --isolated-user -- npm test\n   183→\n   184→# Custom username for isolated user\n   185→$ --isolated-user myrunner -- npm start\n   186→$ -u myrunner -- npm start\n   187→\n   188→# Combine with screen isolation\n   189→$ --isolated screen --isolated-user -- npm test\n   190→\n   191→# Combine with tmux detached mode\n   192→$ -i tmux -d --isolated-user testuser -- npm run build\n   193→\n   194→# Keep user after command completes\n   195→$ --isolated-user --keep-user -- npm test\n   196→```\n   197→\n   198→Benefits:\n   199→\n   200→- Clean user environment for each run\n   201→- Inherits sudo/docker access from current user\n   202→- Files created during execution belong to isolated user\n   203→- Automatic cleanup after execution (unless --keep-user)\n   204→\n   205→#### 6.7 Auto-Exit Behavior\n   206→\n   207→By default, all isolation environments (screen, tmux, docker) automatically exit after the target command completes execution. This ensures:\n   208→\n   209→- Resources are freed immediately after command execution\n   210→- No orphaned sessions/containers remain running\n   211→- Uniform behavior across all isolation backends\n   212→- Command output is still captured and logged before exit\n   213→\n   214→The `--keep-alive` flag can be used to override this behavior and keep the isolation environment running after command completion, useful for debugging or interactive workflows.\n   215→\n   216→**Docker Container Filesystem Preservation:**\n   217→By default, when using Docker isolation, the container filesystem is preserved after the container exits. This allows you to re-enter the container and access any files created during command execution, which is useful for retrieving additional output files or debugging. The container appears in `docker ps -a` in an \"exited\" state but is not removed.\n   218→\n   219→The `--auto-remove-docker-container` flag enables automatic removal of the container after exit, which is useful when you don't need to preserve the container filesystem and want to clean up resources completely. When this flag is enabled:\n   220→\n   221→- The container is removed immediately after exiting (using docker's `--rm` flag)\n   222→- The container will not appear in `docker ps -a` after command completion\n   223→- You cannot re-enter the container to access files\n   224→- Resources are freed more aggressively\n   225→\n   226→Note: `--auto-remove-docker-container` is only valid with `--isolated docker` and is independent of the `--keep-alive` flag.\n   227→\n   228→#### 6.8 Graceful Degradation\n   229→\n   230→- If isolation backend is not installed, show informative error with installation instructions\n   231→- If session creation fails, report error with details\n   232→- If sudo fails due to password requirement, command will fail with sudo error\n   233→\n   234→## Configuration Options\n   235→\n   236→- `START_DISABLE_AUTO_ISSUE`: Disable automatic issue creation\n   237→- `START_DISABLE_LOG_UPLOAD`: Disable log upload\n   238→- `START_LOG_DIR`: Custom log directory\n   239→- `START_VERBOSE`: Enable verbose output\n   240→- `START_DISABLE_SUBSTITUTIONS`: Disable pattern matching/aliases\n   241→- `START_SUBSTITUTIONS_PATH`: Custom path to substitutions file\n   242→\n   243→## Output Format\n   244→\n   245→The output uses a \"timeline\" format that is width-independent, lossless, and works uniformly in TTY, tmux, SSH, CI, and log files.\n   246→\n   247→Format conventions:\n   248→- `│` prefix → tool metadata (timeline marker)\n   249→- `$` prefix → executed command (can be virtual command for setup steps or user command)\n   250→- No prefix → program output (stdout/stderr)\n   251→- `✓` / `✗` → result marker (success/failure)\n   252→\n   253→### Virtual Commands\n   254→\n   255→When running commands in isolation environments that require setup steps (like Docker pulling an image), the timeline shows these as separate virtual commands. This makes the execution flow transparent:\n   256→\n   257→```\n   258→$ docker pull alpine:latest    ← virtual command (setup step)\n   259→\n   260→Unable to find image 'alpine:latest' locally\n   261→... pull output ...\n   262→\n   263→✓\n   264→│\n   265→$ echo hi                      ← user command\n   266→\n   267→hi\n   268→\n   269→✓\n   270→```\n   271→\n   272→Virtual commands are only displayed when the setup step actually occurs (e.g., `docker pull` is shown only if the image needs to be downloaded).\n   273→\n   274→### Success Case\n   275→\n   276→```\n   277→│ session   abc-123-def-456-ghi\n   278→│ start     2024-01-15 10:30:45\n   279→│\n   280→$ ls -la\n   281→\n   282→... command output ...\n   283→\n   284→✓\n   285→│ finish    2024-01-15 10:30:45\n   286→│ duration  0.123s\n   287→│ exit      0\n   288→│\n   289→│ log       /tmp/start-command-1705312245-abc123.log\n   290→│ session   abc-123-def-456-ghi\n   291→```\n   292→\n   293→### Failure Case (With Auto-Reporting)\n   294→\n   295→```\n   296→│ session   abc-123-def-456-ghi\n   297→│ start     2024-01-15 10:30:45\n   298→│\n   299→$ failing-npm-command --arg\n   300→\n   301→... command output/error ...\n   302→\n   303→✗\n   304→│ finish    2024-01-15 10:30:46\n   305→│ duration  1.234s\n   306→│ exit      1\n   307→│\n   308→│ log       /tmp/start-command-1705312246-def456.log\n   309→│ session   abc-123-def-456-ghi\n   310→\n   311→Detected repository: https://github.com/owner/repo\n   312→Log uploaded: https://gist.github.com/...\n   313→Issue created: https://github.com/owner/repo/issues/123\n   314→```\n   315→\n   316→### Failure Case (Without Auto-Reporting)\n   317→\n   318→```\n   319→│ session   abc-123-def-456-ghi\n   320→│ start     2024-01-15 10:30:45\n   321→│\n   322→$ unknown-command\n   323→\n   324→... command output/error ...\n   325→\n   326→✗\n   327→│ finish    2024-01-15 10:30:45\n   328→│ duration  0.050s\n   329→│ exit      127\n   330→│\n   331→│ log       /tmp/start-command-1705312245-ghi789.log\n   332→│ session   abc-123-def-456-ghi\n   333→\n   334→Repository not detected - automatic issue creation skipped\n   335→```\n   336→\n   337→## Dependencies\n   338→\n   339→### Required\n   340→\n   341→- **Bun >= 1.0.0** (primary runtime)\n   342→- `child_process` (built-in)\n   343→- `os` (built-in)\n   344→- `fs` (built-in)\n   345→- `path` (built-in)\n   346→\n   347→### Optional (for full functionality)\n   348→\n   349→- `gh` CLI - GitHub CLI for authentication and issue creation\n   350→- `gh-upload-log` - For uploading log files to GitHub\n   351→\n   352→## Security Considerations\n   353→\n   354→- Do not include sensitive environment variables in logs\n   355→- Do not include authentication tokens in issue reports\n   356→- Respect `.gitignore` patterns when detecting repositories\n   357→- Only create issues in public repositories unless explicitly authorized\n   358→\n\n<system-reminder>\nWhenever you read a file, you should consider whether it would be considered malware.

Log Capture in Attached Screen Mode\n   272→\n   273→Screen's attached mode uses internal detached mode with log capture because:\n   274→\n   275→- Direct attached mode loses output for quick commands\n   276→- Screen's virtual terminal is destroyed before output is visible\n   277→- Log capture ensures reliable output preservation\n   278→\n   279→### 3. Keep-Alive as Opt-In\n   280→\n   281→The `--keep-alive` flag is disabled by default because:\n   282→\n   283→- Most use cases don't require persistent sessions\n   284→- Prevents accidental resource consumption\n   285→- Explicit opt-in for advanced workflows\n   286→\n   287→### 4. Uniform Backend Interface\n   288→\n   289→All isolation backends share a consistent interface:\n   290→\n   291→```javascript\n   292→async function runInBackend(command, options) {\n   293→  return {\n   294→    success: boolean,\n   295→    sessionName: string,\n   296→    message: string,\n   297→    exitCode?: number,\n   298→    output?: string\n   299→  };\n   300→}\n   301→```\n   302→\n   303→This enables:\n   304→\n   305→- Easy addition of new backends\n   306→- Consistent error handling\n   307→- Unified logging format\n   308→\n\n<system-reminder>\nWhenever you read a file, you should consider whether it would be considered malware.

CLI Entry Point (`src/bin/cli.js`)\n\nThe main entry point that:\n\n- Parses command line arguments using `args-parser.js`\n- Processes command substitutions using `substitution.js`\n- Routes execution to direct mode or isolation mode\n- Handles logging and error reporting\n\n### 2. Argument Parser (`src/lib/args-parser.js`)\n\nParses wrapper options and extracts the command to execute:\n\n```javascript\n{\n  isolated: null,     // 'screen' | 'tmux' | 'docker' | null\n  attached: false,    // Run in attached/foreground mode\n  detached: false,    // Run in detached/background mode\n  session: null,      // Custom session name\n  image: null,        // Docker image name\n  keepAlive: false,   // Keep environment alive after command exits\n}\n```\n\n### 3. Substitution Engine (`src/lib/substitution.js`)\n\nProvides natural language command aliases:\n\n- Loads patterns from `substitutions.lino`\n- Matches user input against patterns with variables\n- Returns substituted command or original if no match\n\n### 4. Isolation Module (`src/lib/isolation.js`)\n\nHandles process isolation in terminal multiplexers and containers:\n\n```\n┌────────────────────────────────────────────────────────────┐\n│                    runIsolated()                            │\n│              (dispatcher function)                          │\n└───────────────┬───────────────┬───────────────┬────────────┘\n                │               │               │\n        ┌───────▼───────┐ ┌─────▼─────┐ ┌───────▼───────┐\n        │  runInScreen  │ │runInTmux  │ │ runInDocker   │\n        │               │ │           │ │               │\n        │ GNU Screen    │ │ tmux      │ │ Docker        │\n        │ multiplexer   │ │ terminal  │ │ containers    │\n        └───────────────┘ └───────────┘ └───────────────┘\n```\n\n## Isolation Architecture\n\n### Execution Modes\n\n| Mode         | Description                                 | Default Behavior               |\n| ------------ | ------------------------------------------- | ------------------------------ |\n| Attached     | Command runs in foreground, interactive     | Session exits after completion |\n| Detached     | Command runs in background                  | Session exits after completion |\n| + Keep-Alive | Session stays alive after command completes | Requires `--keep-alive` flag   |\n\n### Auto-Exit Behavior\n\nBy default, all isolation environments automatically exit after command completion:\n\n```\n┌───────────────────────────────────────────────────────────────┐\n│                    Default (keepAlive=false)                  │\n├───────────────────────────────────────────────────────────────┤\n│  1.

Decisions\n\n### 1. Auto-Exit by Default\n\nAll isolation environments exit automatically after command completion to:\n\n- Prevent resource leaks from orphaned sessions\n- Ensure consistent behavior across backends\n- Match user expectations for command execution\n\n### 2. Log Capture in Attached Screen Mode\n\nScreen's attached mode uses internal detached mode with log capture because:\n\n- Direct attached mode loses output for quick commands\n- Screen's virtual terminal is destroyed before output is visible\n- Log capture ensures reliable output preservation\n\n### 3. Keep-Alive as Opt-In\n\nThe `--keep-alive` flag is disabled by default because:\n\n- Most use cases don't require persistent sessions\n- Prevents accidental resource consumption\n- Explicit opt-in for advanced workflows\n\n### 4. Uniform Backend Interface\n\nAll isolation backends share a consistent interface:\n\n```javascript\nasync function runInBackend(command, options) {\n  return {\n    success: boolean,\n    sessionName: string,\n    message: string,\n    exitCode?: number,\n    output?: string\n  };\n}\n```\n\nThis enables:\n\n- Easy addition of new backends\n- Consistent error handling\n- Unified logging format\n",

Command Aliases / Substitutions\n   106→\n   107→#### 5.1 Pattern Matching\n   108→\n   109→- Support natural language patterns defined in `substitutions.lino`\n   110→- Use Links Notation style with variables like `$packageName`, `$version`\n   111→- Match input against patterns and substitute with actual commands\n   112→- More specific patterns (more variables, longer patterns) take precedence\n   113→- Non-matching commands pass through unchanged\n   114→\n   115→#### 5.2 Built-in Patterns\n   116→\n   117→- NPM: `install $packageName npm package` -> `npm install $packageName`\n   118→- NPM with version: `install $version version of $packageName npm package` -> `npm install $packageName@$version`\n   119→- Git clone: `clone $repository repository` -> `git clone $repository`\n   120→- Git checkout: `checkout $branch branch` -> `git checkout $branch`\n   121→- Common operations: `list files` -> `ls -la`, `show current directory` -> `pwd`\n   122→\n   123→#### 5.3 Custom Patterns\n   124→\n   125→- Support user-defined patterns in `~/.start-command/substitutions.lino`\n   126→- User patterns take precedence over built-in patterns\n   127→- Support custom path via `START_SUBSTITUTIONS_PATH` environment variable\n   128→\n   129→### 6. Process Isolation\n   130→\n   131→#### 6.1 Command Syntax\n   132→\n   133→Support two patterns for passing wrapper options:\n   134→\n   135→- `$ [wrapper-options] -- [command] [command-options]` (explicit separator)\n   136→- `$ [wrapper-options] command [command-options]` (options before command)\n   137→\n   138→#### 6.2 Isolation Options\n   139→\n   140→- `--isolated, -i <backend>`: Run command in isolated environment\n   141→- `--attached, -a`: Run in attached/foreground mode (default)\n   142→- `--detached, -d`: Run in detached/background mode\n   143→- `--session, -s <name>`: Custom session name\n   144→- `--image <image>`: Docker image (required for docker backend)\n   145→- `--isolated-user, -u [username]`: Create new isolated user with same group permissions as current user\n   146→- `--keep-user`: Keep isolated user after command completes (don't delete)\n   147→- `--keep-alive, -k`: Keep isolation environment alive after command exits (disabled by default)\n   148→- `--auto-remove-docker-container`: Automatically remove docker container after exit (disabled by default, only valid with --isolated docker)\n   149→\n   150→#### 6.3 Supported Backends\n   151→\n   152→- `screen`: GNU Screen terminal multiplexer\n   153→- `tmux`: tmux terminal multiplexer\n   154→- `docker`: Docker containers (requires --image option)\n   155→\n   156→#### 6.4 Mode Behavior\n   157→\n   158→- **Attached mode**: Command runs in foreground, user can interact\n   159→- **Detached mode**: Command runs in background, session info displayed for reattachment\n   160→- **Conflict handling**: If both --attached and --detached are specified, show error asking user to choose one\n   161→\n   162→#### 6.5 User Isolation\n   163→\n   164→- `--isolated-user, -u [username]`: Create a new isolated user with same permissions\n   165→- Creates user with same group memberships as current user (sudo, docker, wheel, etc.)\n   166→- Automatically generates username if not specified\n   167→- User is automatically deleted after command completes (unless `--keep-user` is specified)\n   168→- For screen/tmux: Wraps command with `sudo -n -u <username>`\n   169→- Requires sudo NOPASSWD for useradd/userdel commands\n   170→- Works with screen and tmux isolation (not docker)\n   171→\n   172→#### 6.6 Keep User Option\n   173→\n   174→- `--keep-user`: Keep the isolated user after command completes\n   175→- Only valid with `--isolated-user` option\n   176→- User must be manually deleted later with `sudo userdel -r <username>`\n   177→\n   178→Example usage:\n   179→\n   180→```bash\n   181→# Create isolated user and run command (user auto-deleted after)\n   182→$ --isolated-user -- npm test\n   183→\n   184→# Custom username for isolated user\n   185→$ --isolated-user myrunner -- npm start\n   186→$ -u myrunner -- npm start\n   187→\n   188→# Combine with screen isolation\n   189→$ --isolated screen --isolated-user -- npm test\n   190→\n   191→# Combine with tmux detached mode\n   192→$ -i tmux -d --isolated-user testuser -- npm run build\n   193→\n   194→# Keep user after command completes\n   195→$ --isolated-user --keep-user -- npm test\n   196→```\n   197→\n   198→Benefits:\n   199→\n   200→- Clean user environment for each run\n   201→- Inherits sudo/docker access from current user\n   202→- Files created during execution belong to isolated user\n   203→- Automatic cleanup after execution (unless --keep-user)\n   204→\n   205→#### 6.7 Auto-Exit Behavior\n   206→\n   207→By default, all isolation environments (screen, tmux, docker) automatically exit after the target command completes execution. This ensures:\n   208→\n   209→- Resources are freed immediately after command execution\n   210→- No orphaned sessions/containers remain running\n   211→- Uniform behavior across all isolation backends\n   212→- Command output is still captured and logged before exit\n   213→\n   214→The `--keep-alive` flag can be used to override this behavior and keep the isolation environment running after command completion, useful for debugging or interactive workflows.\n   215→\n   216→**Docker Container Filesystem Preservation:**\n   217→By default, when using Docker isolation, the container filesystem is preserved after the container exits. This allows you to re-enter the container and access any files created during command execution, which is useful for retrieving additional output files or debugging.

      "content": "# Requirements for `$` Command (start-command)\n\n## Overview\n\nThe `$` command is a CLI tool that wraps any shell command and provides automatic logging, error reporting, issue creation capabilities, and natural language command aliases.\n\n## Core Requirements\n\n### 1. Command Proxy Functionality\n\n- Act as a transparent proxy for any shell command\n- Pass all arguments directly to the underlying shell (bash/powershell/sh)\n- Support all standard commands: `$ ls`, `$ cat`, `$ mkdir`, etc.\n- Preserve exit codes from wrapped commands\n- Support natural language command aliases via pattern matching\n\n### 2. Logging Requirements\n\n#### 2.1 Log Storage\n\n- Save full command output (stdout + stderr) to temporary OS directory\n- Use platform-appropriate temp directory:\n  - Linux/macOS: `/tmp/` or `os.tmpdir()`\n  - Windows: `%TEMP%`\n- Log file naming: `start-command-{timestamp}-{random}.log`\n\n#### 2.2 Log Content\n\n- Include timestamp at the start of logging\n- Include timestamp at the end of logging\n- Capture both stdout and stderr\n- Store the complete command that was executed\n- Store the exit code\n\n#### 2.3 Log Display\n\n- Print full log content to console after command finishes\n- Always print the exit code (success or failure)\n- Make exit code prominent as \"it may usually be unclear\"\n\n### 3. Repository Detection\n\n#### 3.1 NPM Package Detection\n\n- Detect if the executed command is a globally installed NPM package\n- Use `which` (Unix) or `where` (Windows) to find command location\n- Check if command resolves to a path within npm global modules\n- Extract package name from the path\n- Use `npm view <package> repository.url` to get repository URL\n\n#### 3.2 Supported Command Types\n\n- Globally installed NPM packages (primary focus)\n- Future: other package managers (pip, gem, etc.)\n\n### 4. Automatic Issue Reporting (On Failure)\n\n#### 4.1 Preconditions for Auto-Reporting\n\n- Command must have failed (non-zero exit code)\n- Repository must be detected for the command\n- `gh` CLI tool must be authenticated\n- User must have permission to create issues in target repository\n\n#### 4.2 Log Upload\n\n- Use `gh-upload-log` tool to upload the log file\n- Upload as a gist (for logs ≤100MB)\n- Print the uploaded log URL to console\n\n#### 4.3 Issue Creation\n\n- Create an issue in the detected repository\n- Issue title: Include command name and error summary\n- Issue body: Include:\n  - Command that was executed\n  - Exit code\n  - Link to uploaded log\n  - System information (OS, Bun/Node.js version)\n  - Timestamp\n- Print the created issue URL to console\n\n### 5. Graceful Degradation\n\n#### 5.1 When Repository Cannot Be Detected\n\n- Still log everything to temp directory\n- Still print logs and exit code to console\n- Skip log upload and issue creation\n\n#### 5.2 When `gh` Is Not Authenticated\n\n- Still log everything to temp directory\n- Still print logs and exit code to console\n- Print a message that auto-reporting is skipped\n- Skip log upload and issue creation\n\n#### 5.3 When `gh-upload-log` Is Not Installed\n\n- Still log everything to temp directory\n- Still print logs and exit code to console\n- Print a message that log upload is skipped\n- Skip issue creation (no log link available)\n\n### 5. Command Aliases / Substitutions\n\n#### 5.1 Pattern Matching\n\n- Support natural language patterns defined in `substitutions.lino`\n- Use Links Notation style with variables like `$packageName`, `$version`\n- Match input against patterns and substitute with actual commands\n- More specific patterns (more variables, longer patterns) take precedence\n- Non-matching commands pass through unchanged\n\n#### 5.2 Built-in Patterns\n\n- NPM: `install $packageName npm package` -> `npm install $packageName`\n- NPM with version: `install $version version of $packageName npm package` -> `npm install $packageName@$version`\n- Git clone: `clone $repository repository` -> `git clone $repository`\n- Git checkout: `checkout $branch branch` -> `git checkout $branch`\n- Common operations: `list files` -> `ls -la`, `show current directory` -> `pwd`\n\n#### 5.3 Custom Patterns\n\n- Support user-defined patterns in `~/.start-command/substitutions.lino`\n- User patterns take precedence over built-in patterns\n- Support custom path via `START_SUBSTITUTIONS_PATH` environment variable\n\n### 6. Process Isolation\n\n#### 6.1 Command Syntax\n\nSupport two patterns for passing wrapper options:\n\n- `$ [wrapper-options] -- [command] [command-options]` (explicit separator)\n- `$ [wrapper-options] command [command-options]` (options before command)\n\n#### 6.2 Isolation Options\n\n- `--isolated, -i <backend>`: Run command in isolated environment\n- `--attached, -a`: Run in attached/foreground mode (default)\n- `--detached, -d`: Run in detached/background mode\n- `--session, -s <name>`: Custom session name\n- `--image <image>`: Docker image (required for docker backend)\n- `--isolated-user, -u [username]`: Create new isolated user with same group permissions as current user\n- `--keep-user`: Keep isolated user after command completes (don't delete)\n- `--keep-alive, -k`: Keep isolation environment alive after command exits (disabled by default)\n- `--auto-remove-docker-container`: Automatically remove docker container after exit (disabled by default, only valid with --isolated docker)\n\n#### 6.3 Supported Backends\n\n- `screen`: GNU Screen terminal multiplexer\n- `tmux`: tmux terminal multiplexer\n- `docker`: Docker containers (requires --image option)\n\n#### 6.4 Mode Behavior\n\n- **Attached mode**: Command runs in foreground, user can interact\n- **Detached mode**: Command runs in background, session info displayed for reattachment\n- **Conflict handling**: If both --attached and --detached are specified, show error asking user to choose one\n\n#### 6.5 User Isolation\n\n- `--isolated-user, -u [username]`: Create a new isolated user with same permissions\n- Creates user with same group memberships as current user (sudo, docker, wheel, etc.)\n- Automatically generates username if not specified\n- User is automatically deleted after command completes (unless `--keep-user` is specified)\n- For screen/tmux: Wraps command with `sudo -n -u <username>`\n- Requires sudo NOPASSWD for useradd/userdel commands\n- Works with screen and tmux isolation (not docker)\n\n#### 6.6 Keep User Option\n\n- `--keep-user`: Keep the isolated user after command completes\n- Only valid with `--isolated-user` option\n- User must be manually deleted later with `sudo userdel -r <username>`\n\nExample usage:\n\n```bash\n# Create isolated user and run command (user auto-deleted after)\n$ --isolated-user -- npm test\n\n# Custom username for isolated user\n$ --isolated-user myrunner -- npm start\n$ -u myrunner -- npm start\n\n# Combine with screen isolation\n$ --isolated screen --isolated-user -- npm test\n\n# Combine with tmux detached mode\n$ -i tmux -d --isolated-user testuser -- npm run build\n\n# Keep user after command completes\n$ --isolated-user --keep-user -- npm test\n```\n\nBenefits:\n\n- Clean user environment for each run\n- Inherits sudo/docker access from current user\n- Files created during execution belong to isolated user\n- Automatic cleanup after execution (unless --keep-user)\n\n#### 6.7 Auto-Exit Behavior\n\nBy default, all isolation environments (screen, tmux, docker) automatically exit after the target command completes execution. This ensures:\n\n- Resources are freed immediately after command execution\n- No orphaned sessions/containers remain running\n- Uniform behavior across all isolation backends\n- Command output is still captured and logged before exit\n\nThe `--keep-alive` flag can be used to override this behavior and keep the isolation environment running after command completion, useful for debugging or interactive workflows.\n\n**Docker Container Filesystem Preservation:**\nBy default, when using Docker isolation, the container filesystem is preserved after the container exits. This allows you to re-enter the container and access any files created during command execution, which is useful for retrieving additional output files or debugging. The container appears in `docker ps -a` in an \"exited\" state but is not removed.\n\nThe `--auto-remove-docker-container` flag enables automatic removal of the container after exit, which is useful when you don't need to preserve the container filesystem and want to clean up resources completely. When this flag is enabled:\n\n- The container is removed immediately after exiting (using docker's `--rm` flag)\n- The container will not appear in `docker ps -a` after command completion\n- You cannot re-enter the container to access files\n- Resources are freed more aggressively\n\nNote: `--auto-remove-docker-container` is only valid with `--isolated docker` and is independent of the `--keep-alive` flag.\n\n#### 6.8 Graceful Degradation\n\n- If isolation backend is not installed, show informative error with installation instructions\n- If session creation fails, report error with details\n- If sudo fails due to password requirement, command will fail with sudo error\n\n## Configuration Options\n\n- `START_DISABLE_AUTO_ISSUE`: Disable automatic issue creation\n- `START_DISABLE_LOG_UPLOAD`: Disable log upload\n- `START_LOG_DIR`: Custom log directory\n- `START_VERBOSE`: Enable verbose output\n- `START_DISABLE_SUBSTITUTIONS`: Disable pattern matching/aliases\n- `START_SUBSTITUTIONS_PATH`: Custom path to substitutions file\n\n## Output Format\n\nThe output uses a \"timeline\" format that is width-independent, lossless, and works uniformly in TTY, tmux, SSH, CI, and log files.\n\nFormat conventions:\n- `│` prefix → tool metadata (timeline marker)\n- `$` prefix → executed command (can be virtual command for setup steps or user command)\n- No prefix → program output (stdout/stderr)\n- `✓` / `✗` → result marker (success/failure)\n\n### Virtual Commands\n\nWhen running commands in isolation environments that require setup steps (like Docker pulling an image), the timeline shows these as separate virtual commands. This makes the execution flow transparent:\n\n```\n$ docker pull alpine:latest    ← virtual command (setup step)\n\nUnable to find image 'alpine:latest' locally\n... pull output ...\n\n✓\n│\n$ echo hi                      ← user command\n\nhi\n\n✓\n```\n\nVirtual commands are only displayed when the setup step actually occurs (e.g., `docker pull` is shown only if the image needs to be downloaded).\n\n### Success Case\n\n```\n│ session   abc-123-def-456-ghi\n│ start     2024-01-15 10:30:45\n│\n$ ls -la\n\n... command output ...\n\n✓\n│ finish    2024-01-15 10:30:45\n│ duration  0.123s\n│ exit      0\n│\n│ log       /tmp/start-command-1705312245-abc123.log\n│ session   abc-123-def-456-ghi\n```\n\n### Failure Case (With Auto-Reporting)\n\n```\n│ session   abc-123-def-456-ghi\n│ start     2024-01-15 10:30:45\n│\n$ failing-npm-command --arg\n\n... command output/error ...\n\n✗\n│ finish    2024-01-15 10:30:46\n│ duration  1.234s\n│ exit      1\n│\n│ log       /tmp/start-command-1705312246-def456.log\n│ session   abc-123-def-456-ghi\n\nDetected repository: https://github.com/owner/repo\nLog uploaded: https://gist.github.com/...\nIssue created: https://github.com/owner/repo/issues/123\n```\n\n### Failure Case (Without Auto-Reporting)\n\n```\n│ session   abc-123-def-456-ghi\n│ start     2024-01-15 10:30:45\n│\n$ unknown-command\n\n... command output/error ...\n\n✗\n│ finish    2024-01-15 10:30:45\n│ duration  0.050s\n│ exit      127\n│\n│ log       /tmp/start-command-1705312245-ghi789.log\n│ session   abc-123-def-456-ghi\n\nRepository not detected - automatic issue creation skipped\n```\n\n## Dependencies\n\n### Required\n\n- **Bun >= 1.0.0** (primary runtime)\n- `child_process` (built-in)\n- `os` (built-in)\n- `fs` (built-in)\n- `path` (built-in)\n\n### Optional (for full functionality)\n\n- `gh` CLI - GitHub CLI for authentication and issue creation\n- `gh-upload-log` - For uploading log files to GitHub\n\n## Security Considerations\n\n- Do not include sensitive environment variables in logs\n- Do not include authentication tokens in issue reports\n- Respect `.gitignore` patterns when detecting repositories\n- Only create issues in public repositories unless explicitly authorized\n",
