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

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

Iron Laws

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

Skill Creator

by anthropics

vendor ×10

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Replace with description of the skill and when Claude should use it.

Dispatching Parallel Agents

by ZhanlinCui

×5

Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies

This skill should be used when the user wants to "create a skill", "add a skill to plugin", "write a new skill", "improve skill description", "organize skill content", or needs guidance on skill structure, progressive disclosure, or skill development best practices for Claude Code plugins.

Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.

Use when creating new skills, editing existing skills, or verifying skills work before deployment

How to use it

Copy the folder

Take oliver-kriska/docs-check from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
