Google Cloud skills (local catalog)

The catalog is a local, pinned copy: /Users/jjmartres/Repositories/perso/ai-coding-agents/generated/google-skills-index.local.json. Every entrypoint in it is a local file path.

1. Filter the catalog by keyword. Never read it in full: jq -r '.skills[] | select((.name+" "+.description)|test("KEYWORD1|KEYWORD2";"i")) | "\(.name)\t\(.entrypoint)"' /Users/jjmartres/Repositories/perso/ai-coding-agents/generated/google-skills-index.local.json
2. Read the matching descriptions as routing criteria. Shortlist at most 3 skills; prefer the most specific.
3. Read the shortlisted SKILL.md files from their local entrypoint path and follow them.
4. Never fetch anything from the internet for this catalog. If no skill matches, say so in one line and continue without one. Never invent a skill.
5. If the index file is missing, tell the user to run /Users/jjmartres/Repositories/perso/ai-coding-agents/scripts/google-skills-gen-index.fish, then continue without it.
6. Project conventions (AGENTS.md) take precedence over generic skill guidance.
7. If a specific Google skill is already loaded and covers the task, use it directly.
