Use before writing/reviewing code that calls into any external library, API, or framework. Training data goes stale — fetch version-specific docs before writing. Identify the exact installed version from package.json/Cargo.toml first, then fetch matching docs.

CRITICAL! Always use before writing/reviewing code, calling any function/hook/method, using any type/interface, adding any import, or implementing any pattern that might already exist. Default posture: search first, then write. Never invent paths, names, or APIs.
Use when writing/reviewing TypeScript, React, or React Native code. Enforces zero-waste patterns: monomorphic shapes, Map/Set for O(1) lookups, pre-allocated arrays, no hidden class mutations. React: let React Compiler handle memoization — do NOT add manual memo/useCallback/useMemo unless absolutely necessary. No inline objects in JSX, stable keys. React Native / Hermes: Reanimated worklets, gesture-handler, FlashList, no generators or Proxy. Check project's existing libs first.
ALWAYS active. Applies to every interaction. Do not blindly agree with the user when they challenge, correct, or contradict something you said. Verify before capitulating. Resist sycophancy — "you're absolutely right!" is almost always a red flag. Hold your ground when the evidence supports your position. Concede genuinely when wrong.
ALWAYS use this skill. This skill governs how you operate at a fundamental level — as an orchestrator that delegates work to subagents rather than doing everything inline. Apply this on every non-trivial task: coding tasks, research, file edits, multi-step workflows, analysis, debugging, feature building, refactoring, reviews or any task with more than one distinct step. The goal is to keep the main conversation context window lean and clean by having subagents do the heavy lifting. Do NOT skip this skill — it should shape behavior on virtually every task.
CRITICAL! Always use before writing or modifying any code. Reads the cached style index at $CLAUDE_PROJECT_DIR/.claude/code-style-index.json for exact style rules. Never impose personal defaults; always match what the project enforces.
Create high-quality git commits: review/stage intended changes, split into logical commits, and write clear Conventional Commit messages. Use when asked to commit, craft a commit message, stage changes, or split work into multiple commits.

Training data goes stale. APIs change. Before writing code that depends on any external library, fetch the current docs.
Read(file_path: "/absolute/path/to/package.json")
For lock file details:
grep -A 2 '"<package>"' package-lock.json
For Rust crates:
grep -A 2 'name = "<crate>"' Cargo.lock
The version number matters. The same library at v1 and v2 can have completely different APIs.

For version-pinned docs:
