Core Dynamic Skills

Dynamic Skills Manager

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:

1. Detect Cargo.toml (single or workspace)
2. Parse dependencies list
3. Check which crates are missing skills
4. If missing: "Found X dependencies without skills. Sync now?"
5. 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

Architecture

Cargo.toml

Parse dependencies
    ↓
For each crate:
  ├─ Check ~/.claude/skills/{crate}/
  ├─ If missing: Check actionbook for llms.txt
  │     ├─ Found: /create-skills-via-llms
  │     └─ Not found: /create-llms-for-skills first
  └─ Load skill

Workflow Priority

1. actionbook MCP - Check for pre-generated llms.txt
2. /create-llms-for-skills - Generate llms.txt from docs.rs
3. /create-skills-via-llms - Create skills from llms.txt

Workspace Support

For Cargo workspace projects:

1. Parse root Cargo.toml for [workspace] members
2. Collect all member Cargo.toml paths
3. Aggregate all dependencies
4. Deduplicate before skill generation
