skills/tool-discovery/SKILL.md
Recommend the right agents and skills for any task. Covers both heavyweight agents (Task tool) and lightweight skills (Skill tool). Triggers on: which agent, which skill, what tool should I use, help me choose, recommend agent, find the right tool.

Recommend the right agents and skills for any task.
Is this a reference/lookup task?
├── YES → Use a SKILL (lightweight, auto-injects)
└── NO → Does it require reasoning/decisions?
├── YES → Use an AGENT (heavyweight, spawns subagent)
└── MAYBE → Check catalogs below
Rule: Skills = patterns/reference. Agents = decisions/expertise.

For Cloudflare/Workers, Cypress/E2E, shell scripting, Claude Code extension work, and CMS/device domains (Payload, Craft, Asus routers), use the matching -ops skill (cloudflare-ops, cypress-ops, bash-ops, claude-code-ops, payloadcms-ops, craftcms-ops, asus-router-ops). For language/framework work (Python, TypeScript, React, Postgres, etc.), use the matching -ops skill — or dispatch general-purpose with an instruction to read that skill's SKILL.md first.

yt-dlp operations - the media ACQUISITION layer that feeds ffmpeg-ops: format selection (-S sort vs -f filters) that avoids post-download transcodes, --download-sections clip-at-download, audio-only extraction for STT pipelines (-x --audio-format opus), playlists + --download-archive incremental channel syncs, cookies/auth (--cookies-from-browser), rate limiting and politeness, SponsorBlock mark/remove, output templates (-o), subtitle download (--write-subs/--write-auto-subs), remux-vs-recode doctrine, and failure triage (403s, throttling, geo blocks, the nsig-extraction class that means yt-dlp is outdated).
