Use when scraping JavaScript-heavy pages or SPAs, crawling multiple URLs concurrently, extracting structured data with reusable CSS/JSON schemas, or building automated web data pipelines. Wraps the Crawl4AI library (`crwl` CLI and Python SDK) with schema-generation patterns for LLM-free extraction. Triggers on crawl4ai, crwl, scrape JS-heavy site, scrape SPA, headless browser scrape, schema-based extraction, batch crawl, sitemap crawl, web data pipeline. SKIP when a static HTML page can be read with `defuddle` / `fetch-web` — those are faster cold-start and don't need a browser.

Guide to designing, building, and auditing CLI tools for use by AI agents. Pairs with [`anc`](https://github.com/brettdavies/agentnative-cli) (the canonical compliance auditor) and [`agentnative-spec`](https://github.com/brettdavies/agentnative) (the canonical principle text, vendored at `spec/`). Provides starter templates, language-specific implementation idioms (Rust/clap, Python Click & argparse, Go Cobra, JS Commander/yargs/oclif, Ruby Thor), and a getting-started guide that points agents at `anc audit --output json` (scorecard schema 0.7) and `anc skill install <host>` / `anc skill update --all`. Use when designing a new CLI tool, building a Rust/clap binary intended for agents, reviewing one for agent-readiness, claiming the agent-native badge (≥70% credit-weighted score), or remediating findings from `anc`. Triggers on agentic CLI, agent-native, CLI design, CLI standard, agent-first, CLI for agents, agent-friendly CLI, CLI compliance, agent-readiness, anc, anc audit, anc emit schema, anc skill install

Drive the X (Twitter) API from the command line via `xr`, the xurl-rs CLI. Use when the user wants to post or thread, reply, quote, delete, like, repost, bookmark, follow, mute, block, send DMs, search recent posts, read a timeline or mentions, look up a user, upload media, stream filtered tweets, hit a raw `/2/...` endpoint, manage OAuth2 / OAuth1 / Bearer auth, register multiple X apps, inspect token state, check API usage caps, or validate a tweet/user JSON payload against the typed response schema. Triggers on "post to X", "post to Twitter", "tweet from CLI", "X API call", "OAuth2 X", "xurl", "xr command", "search tweets", "send DM", "follow on X".

Drive the `bird` CLI for the X (Twitter) API — entity-store-backed reads (`--refresh` / `--no-cache` / `--cache-only`), watchlist monitoring, thread reconstruction, API usage and cost ledger, `bird doctor` self-diagnostics, JSON Schema output documents, search with sort/min-likes/pages, and the bird-specific write-op confirmation flow (`--dry-run`, `--force`, exit 2 `requires-confirmation`). Use when the user wants to read bookmarks or a profile, search recent tweets with ranking, rebuild a conversation thread, manage a watchlist, check API cost, inspect cache, run diagnostics, install the skill bundle, or any task where bird's local cache or structured error envelope matters. For OAuth flows, raw write-op transport, or full xr surface, route to the companion `xurl-rs` skill; for X API v2 endpoint, scope, and billing reference, route to the companion `x-api` skill. Triggers on "bird command", "bird search", "bird watchlist", "bird bookmarks", "bird thread", "bird doctor", "bird cache", "bird usage", "X API co
