Skills collection — agent onboarding

This repo is a collection of agent skills, one per subfolder containing a SKILL.md. When a session starts inside this repo, or when a user pastes an install prompt pointing at it, run this onboarding immediately:

1. Identify the skill the user wants. If they already named one (the install prompts in each skill's README do), use it. Otherwise list the available skills (folders with a SKILL.md, or the table in README.md) and ask. Never install skills the user did not choose, and never touch skills they already have installed.

2. Install it permanently with the bundled installer:

   node install-skills.mjs <skill-name>

   This copies only that skill into ~/.claude/skills/ so it is available in every future chat (use --codex for Codex). Re-running it later updates that skill only. If this is a sparse checkout without install-skills.mjs, copy the skill folder into ~/.claude/skills/<skill-name>/ directly — that is all the installer does.

   To update an already-installed skill, git pull and re-run the same installer command: it preserves the skill's installed node_modules, records the installed commit in .installed-from.json, and prints the old and new commits so you can summarize the changes for the user. node install-skills.mjs <skill-name> --check reports whether the installed copy is behind this checkout (exit 3 = update available) without installing anything. node install-skills.mjs <skill-name> --remove uninstalls: it deletes only that skill's installed copy (never the repo folder, other skills, or the user's project folders) — only run it when the user explicitly asks to remove the skill.

3. Confirm the skill loads, then briefly explain — in the user's language — what it does and how it is used, based on the skill's own README.
4. Offer to start the first job right away. For social-video-producer, ask whether they want a full script-to-video production or an assembly from existing clips/audio. For assembly, offer to fill social-video-producer/PROMPT-template.md together: ask for each placeholder value conversationally, show the filled prompt, and ask "Do I apply this prompt and start?" before proceeding.
5. Check requirements for the chosen skill (Node, ffmpeg, Playwright, API keys per its README) and help set up anything missing.

Once a job starts, always respect the skill's own approval gates and hard rules.
