claude_skills

fact-check

Verify claims in backlog items, skill documentation, or plugin content against primary sources using web lookups. Spawns parallel verification agents that MUST use WebFetch/WebSearch/gh — training data recall is explicitly rejected as evidence. Produces VERIFIED/REFUTED/INCONCLUSIVE verdicts with citations. Triggers on "fact check", "verify claims", "check against primary sources", or when backlog items are marked UNVERIFIED.

planner-rt-ica

Identify required inputs, dependencies, and uncertainty during planning. Use when generating plans or task graphs under incomplete information. Does not block plan generation; instead localizes gaps and creates unblock dependencies.

find-cause

Wrap investigation requests with evidence-chain discipline. Use when the user asks to find out why something happens, look into something, research a root cause, debug an issue, or investigate unexpected behavior. Transforms vague investigation requests into reproducible-proof investigations. Invoke with /find-cause <description of what to investigate>.

clear-cove-task-design

Combine CLEAR (Concise, Logical, Explicit, Adaptive, Reflective) and CoVe (Chain of Verification) to write and lint agent task files that will be executed by worker agents. Use when orchestration or planning agents are producing task plans, task prompts, or TASK.md style instructions that must be unambiguous, verifiable, and resistant to hallucination.

agent-creator

Create high-quality Claude Code agents from scratch or by adapting existing agents as templates. Use when the user wants to create a new agent, modify agent configurations, build specialized subagents, or design agent architectures. Guides through requirements gathering, template selection, and agent file generation following Anthropic best practices (v2.1.63+).

how-to-delegate

Scientific delegation framework for orchestrators — provide observations and success criteria while preserving agent autonomy. Use when assigning work to sub-agents, before invoking the Agent tool, or when preparing delegation prompts for specialist agents.

skill-research-process

Systematic process for building comprehensive Claude Code skills using parallel research agents. Triggers on "research for skill", "build skill from docs", "create comprehensive skill", or when needing to gather extensive documentation from official sources before skill creation.

clang-format

Configure clang-format code formatting. Use when: user mentions clang-format or .clang-format, analyzing code style/patterns, creating/modifying formatting config, troubleshooting formatting, brace styles/indentation/spacing/alignment/pointer alignment, or codifying conventions.

conventional-commits

When writing a git commit message. When task completes and changes need committing. When project uses semantic-release, commitizen, git-cliff. When choosing between feat/fix/chore/docs types. When indicating breaking changes. When generating changelogs from commit history.

add-doc-updater

Add automated documentation updater to any Claude skill. Creates a Python sync script that downloads upstream docs, processes markdown for AI consumption, and maintains local cache with configurable refresh. Collects template variables, then delegates implementation through 5-phase workflow. Use when adding auto-updating reference documentation to plugins or skills.

agent-capability-analyzer

Runs the description-drift experiment — spawns all Claude Code agents simultaneously to collect self-reported capabilities, then compares them against static frontmatter descriptions to reveal how reliable orchestrator routing based on descriptions actually is. Use when measuring description drift across the agent fleet, re-running the capability collection experiment, analyzing a specific agent's self-reported capabilities, or auditing whether frontmatter descriptions accurately reflect agent behavior.

commitlint

When setting up commit message validation for a project. When project has commitlint.config.js or .commitlintrc files. When configuring CI/CD to enforce commit format. When extracting commit rules for LLM prompt generation. When debugging commit message rejection errors.

research-curator

Manage research entries in ./research/ — create, refresh, and validate. Use when asked to add a tool, "document this", "research this", "refresh this research", "validate research entries", or given a tool URL. Modes: default (single URL), --batch (multiple URLs in parallel), --rerun (refresh stale entries), --validate (structural check and auto-fix).

test-failure-mindset

This skill should be used when encountering failing tests or when the user asks about "test failure analysis", "debugging tests", "why tests fail", or needs to set a balanced investigative approach for test failures. Establishes mindset that treats test failures as valuable signals requiring investigation, not automatic dismissal.

orchestrator-discipline

Orchestrator context window discipline enforcement. Prevents the orchestrator from reading source files it will not edit, running diagnostic commands that waste context, and rationalizing delegation bypasses. Use when setting up orchestrator guardrails, reviewing delegation discipline, or diagnosing context window waste in multi-agent workflows. Activates PreToolUse hooks that surface decision points before source file reads and diagnostic command execution.

brainstorming-skill

You MUST use this before any creative work - creating features, building components, adding functionality, modifying behavior, or when users request help with ideation, marketing, and strategic planning. Explores user intent, requirements, and design before implementation using 30+ research-validated prompt patterns.

fastmcp-python-tests

Write and evaluate effective Python tests using pytest. Use when writing tests, reviewing test code, debugging test failures, or improving test coverage. Covers test design, fixtures, parameterization, mocking, and async testing.

gitlab-skill

GitLab CI/CD pipeline configuration and GLFM documentation expertise. Use when modifying .gitlab-ci.yml, optimizing pipelines, testing with gitlab-ci-local, writing GitLab README/Wiki content, configuring Docker-in-Docker workflows, or implementing CI Steps composition.

agentskills

Agent Skills Open Standard reference (agentskills.io). Use when creating portable skills for Claude Code, Cursor, Gemini CLI, OpenAI Codex, VS Code, Roo Code, and 20+ compatible agents. Covers frontmatter schema, naming rules, directory structure, progressive disclosure, validation, and authoring. Load before creating cross-agent skills.

fastmcp-creator

Use when building, extending, or debugging FastMCP v3 Python MCP servers — covers tools, resources, prompts, providers, transforms (including CodeMode and Tool Search), auth (MultiAuth, PropelAuth), client SDK, deployment (nginx reverse proxy), Prefab Apps, and testing. Grounded in local v3.1 docs — zero speculation.

session-historian

Look up prior Claude Code sessions when context is lost or forgotten. Use when asked "what did we do before?", "what happened in the last session?", "I forgot what we were working on", "find what I told you about X", or any request to recall past conversation history, prior decisions, experiments, or outcomes. Searches raw JSONL transcripts from ~/.claude/projects/ via DuckDB index. Returns verbatim user messages and summarizes AI actions and sub-agent outcomes. Summaries cached at ~/.claude/kaizen/session-summaries/.

agent-plugin-ecosystem

Ecosystem awareness for AI agent plugin systems — Claude Code, Cursor, agentskills.io standard, AAIF. Auto-loaded into agents writing skills, agents, or plugin manifests so output targets the correct schema and platform. Describes plugin.json schemas, SKILL.md portability constraints, cross-vendor differences, and self-update instructions when ecosystem changes occur.

rt-ica

Reverse Thinking - Information Completeness Assessment. Mandatory pre-planning checkpoint that blocks planning until prerequisites are verified. Use when receiving specs, PRDs, tickets, RFCs, architecture designs, or any multi-step engineering task. Integrates with CoVe-style planning pipelines. Invoke BEFORE creating plans, delegating to agents, or defining acceptance criteria.

subagent-contract

Global contract for all specialist subagents — enforces role boundaries, scope discipline, and DONE/BLOCKED status signaling. Use when loading any agent that should operate as a bounded specialist following supervisor delegation patterns.

scientific-thinking

Moved — use the scientific-method plugin instead.
