Core Dynamic Skills

This handles the tricky problem of keeping Claude's knowledge current with your Rust project's actual dependencies. When you open a project with a Cargo.toml, it can detect which crates you're using and auto-generate local skills by scraping docs.rs documentation into ~/.claude/skills/. The implementation is clever: it tries to use the full plugin infrastructure with agents and commands if available, but falls back to inline mode with manual browser fetches if you only have the skills system installed. Worth noting that it explicitly won't run unless you invoke it with /sync-crate-skills or related commands, so it stays out of your way until you need it. Solves a real workflow gap for Rust development.

Dynamic Skills Manager

Version: 2.1.0 | Last Updated: 2025-01-27

Orchestrates on-demand generation of crate-specific skills based on project dependencies.

Concept

Dynamic skills are:

Generated locally at ~/.claude/skills/
Based on Cargo.toml dependencies
Created using llms.txt from docs.rs
Versioned and updatable
Not committed to the rust-skills repository

Trigger Scenarios

Prompt-on-Open

When entering a directory with Cargo.toml:

Detect Cargo.toml (single or workspace)
Parse dependencies list
Check which crates are missing skills
If missing: "Found X dependencies without skills. Sync now?"
If confirmed: run /sync-crate-skills

Manual Commands

/sync-crate-skills - Sync all dependencies
/clean-crate-skills [crate] - Remove skills
/update-crate-skill <crate> - Update specific skill

Execution Mode Detection

CRITICAL: Check if agent and command infrastructure is available.

Try to read: ../../agents/ directory Check if /create-llms-for-skills and /create-skills-via-llms commands work.

Agent Mode (Plugin Install)

When full plugin infrastructure is available:
