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:

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

• actionbook MCP - Check for pre-generated llms.txt

• /create-llms-for-skills - Generate llms.txt from docs.rs

• /create-skills-via-llms - Create skills from llms.txt

Sync Command

/sync-crate-skills [--force]

• Parse Cargo.toml for dependencies

• For each dependency:

• Check if skill exists at ~/.claude/skills/{crate}/

• If missing (or --force): generate skill

• Report results

Inline Mode (Skills-only Install)

When agent/command infrastructure is NOT available, execute manually:

Step 1: Parse Cargo.toml

# Read dependencies

cat Cargo.toml | grep -A 100 '\[dependencies\]' | grep -E '^[a-zA-Z]'

Or use Read tool to parse Cargo.toml and extract:

• [dependencies] section

• [dev-dependencies] section (optional)

• Workspace members (if workspace project)

Step 2: Check Existing Skills

# List existing skills

ls ~/.claude/skills/

Compare with dependencies to find missing skills.

Step 3: Generate Missing Skills

For each missing crate:

# 1. Fetch crate documentation

agent-browser open "https://docs.rs/{crate}/latest/{crate}/"

agent-browser get text ".docblock"

# Save content

# 2. Create skill directory

mkdir -p ~/.claude/skills/{crate}

mkdir -p ~/.claude/skills/{crate}/references

# 3. Create SKILL.md

# Use template from rust-skill-creator inline mode

# 4. Create reference files for key modules

agent-browser open "https://docs.rs/{crate}/latest/{crate}/{module}/"

agent-browser get text ".docblock"

# Save to ~/.claude/skills/{crate}/references/{module}.md

agent-browser close

WebFetch fallback:

WebFetch("https://docs.rs/{crate}/latest/{crate}/", "Extract API documentation overview, key types, and usage examples")

Step 4: Workspace Support

For Cargo workspace projects:

# 1. Parse root Cargo.toml for workspace members

cat Cargo.toml | grep -A 10 '\[workspace\]'

# 2. For each member, parse their Cargo.toml

for member in members; do

  cat ${member}/Cargo.toml | grep -A 100 '\[dependencies\]'

done

# 3. Aggregate and deduplicate dependencies

# 4. Generate skills for missing crates

Clean Command (Inline)

# Clean specific crate

rm -rf ~/.claude/skills/{crate_name}

# Clean all generated skills

rm -rf ~/.claude/skills/*

Update Command (Inline)

# Remove old skill

rm -rf ~/.claude/skills/{crate_name}

# Re-generate (same as sync for single crate)

# Follow Step 3 above for the specific crate
