Docs Check

Plugin Documentation Compatibility Check

Validates plugin agents, skills, hooks, and config against the latest Claude Code documentation to catch breaking changes and discover new features.

Usage

/docs-check                    # Full validation (all components)
/docs-check --quick            # Structural checks only (no docs fetch, no tokens)
/docs-check --focus=agents     # Validate only agents
/docs-check --focus=skills     # Validate only skills
/docs-check --focus=hooks      # Validate only hooks
/docs-check --focus=config     # Validate only plugin.json/marketplace.json

Execution

Step 1: Fetch Docs (Automatic)

Always run first. Downloads all doc pages to cache. Skips pages already cached within 24h. Zero token cost — pure curl.

# --quick mode: skip this step entirely (structural checks only)
# All other modes: always fetch
bash scripts/fetch-claude-docs.sh

Step 2: Delegate to Orchestrator

After docs are cached, delegate. The orchestrator reads from cache only and crashes if cache files are missing.

Task(subagent_type: "docs-validation-orchestrator")

Pass the user's flags (--quick, --focus) in the prompt.

What the Orchestrator Does

1. Inventory — scan plugins/elixir-phoenix/ for existing components
2. Read cached docs — from .claude/docs-check/docs-cache/ (never fetches)
3. Spawn workers — one sonnet subagent per component type, in parallel
4. Compress — context-supervisor (haiku) if 3+ workers
5. Structural checks — fast local checks, always run
6. Report & Action — write report, offer PR if issues found

Iron Laws

1. Fetch ALL docs upfront — no conditional fetching, no partial downloads
2. Use scripts/fetch-claude-docs.sh — single source of truth for doc fetching
3. Workers get docs IN PROMPT — no runtime fetching
4. Workers use sonnet — opus is wasteful for comparison tasks
5. Structural checks always run — even if docs fetch fails
6. Breaking changes are BLOCKERS — surface prominently
