Native Secure Enclave backed ssh keys on MacOS

It turns out that MacOS Tahoe can generate and use secure-enclave backed SSH keys! This replaces projects like https://github.com/maxgoedjen/secretive

There is a shared library /usr/lib/ssh-keychain.dylib that traditionally has been used to add smartcard support to ssh by implementing PKCS11Provider interface. However since recently it also implements SecurityKeyProivder which supports loading keys directly from the secure enclave! SecurityKeyProvider is what is normally used to talk to FIDO2 devices (e.g. libfido2 can be used to talk to your Yubikey). However you can now use it to talk to your Secure Enclave instead!

Beast Mode

Beast Mode is a custom chat mode for VS Code agent that adds an opinionated workflow to the agent, including use of a todo list, extensive internet research capabilities, planning, tool usage instructions and more. Designed to be used with 4.1, although it will work with any model.

Below you will find the Beast Mode prompt in various versions - starting with the most recent - 3.1

Installation Instructions

Go to the "agent" dropdown in VS Code chat sidebar and select "Configure Modes".
Select "Create new custom chat mode file"

Update Documentation

You will generate LLM-optimized documentation with concrete file references and flexible formatting.

Your Task

Create documentation that allows humans and LLMs to:

Understand project purpose - what the project does and why
Get architecture overview - how the system is organized
Build on all platforms - build instructions with file references

How to use python with the Cursor AI IDE

Cursor.app has a critical vulnerability that should be taken seriously!

Please see my post below on this as sooon as possible! https://gist.github.com/joeblackwaslike/752b26ce92e3699084e1ecfc790f74b2?permalink_comment_id=5716065#gistcomment-5716065

Steps to patch latest cursor

These instructions should work with the latest versions of cursor which requires a much different strategy than the older versions where you could simply point cursor to the MS extension marketplace and call it a day.

	# Extract a JSON value in an object or array:
	#
	# name = decode_json_string(get_json_value(json, "author.name"))
	# date = decode_json_string(get_json_value(json, "events.0.date"))

	# Or an entire object:

	You are an assistant that engages in extremely thorough, self-questioning reasoning. Your approach mirrors human stream-of-consciousness thinking, characterized by continuous exploration, self-doubt, and iterative analysis.

	## Core Principles

	1. EXPLORATION OVER CONCLUSION
	- Never rush to conclusions
	- Keep exploring until a solution emerges naturally from the evidence
	- If uncertain, continue reasoning indefinitely
	- Question every assumption and inference
