ai-dev-operating-system: Skill for Claude Code

.claude/skills/registry-pick/SKILL.md

registry-pick is a skill for Claude Code from lglucas/ai-dev-operating-system. It costs 98 tokens per session (1,474 once invoked), scanned A, original, MIT.

A project-matching shortlist of external repository packs from the project's registry. It considers the project's technology, subject area, design needs, and limits, but does not install anything.

In plain words
What is it for?
It helps choose design, component, diagramming, asset, and other repository packs during project planning.
Why use it?
It removes the guesswork of choosing useful add-ons and avoids recommending design tools too late or technical tools before the plan is clear.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

registry-pick scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Registry Pick

Read docs/registry/INDEX.md and docs/registry/packs/*.md, match the project's signals against pack tags and fit-signals, and produce a short, opinionated recommendation.

This skill does NOT install anything. It shortlists what is worth installing for THIS project.


When to invoke

The wizard invokes this skill twice, in two differently-scoped passes:

Pass WIZARD stage Scope Output
Design 3.1 — before the Prototype Lab Only design-oriented packs: UI systems, design tokens, component libraries, diagramming, screenshot/asset tooling docs/technical/registry-pick-design.md
Stack 4.3 — after the Technical Plan The whole catalog docs/technical/registry-pick.md

The split is deliberate: design packs are worthless once the prototype is already built, and stack packs are guesswork before the Technical Plan exists.

Signals available differ between passes. In the design pass there is no Product Brief, no Technical Plan, and no prototype-lab/ yet — read BP v0.0.2 and knowledge-base/ instead, and do not ask for artifacts that Phase 3 has not produced.

Also invoke:

  • When the user asks "que repos eu uso aqui?", "tem algum pack pra X?", "que skill externa ajuda nisso?".
  • When a new domain need surfaces mid-build (compliance, design system, malware analysis, web3 integration).
  • After adding a new pack to the registry, to retest the recommendation for the current project.

Inputs the skill needs

Before recommending, gather these from the project:

Signal Source Example
Stack package.json, Anchor.toml, requirements.txt, Gemfile, Cargo.toml @solana/web3.js → web3/Solana
Domain docs/business/BUSINESS-PLAN.md, docs/product/PRODUCT-BRIEF.md (stack pass only) "PHI" → healthcare, "pagamentos" → fintech
Compliance docs/technical/TECHNICAL-PLAN.md security/privacy section (stack pass only); BP v0.0.2 risk section in the design pass LGPD, GDPR, HIPAA, PCI
UI surface BP v0.0.2 personas and positioning in the design pass; Product Brief + prototype-lab/ in the stack pass mobile, dashboard, B2C web
Public/private repo metadata, deploy intent public GitHub → enables gitleaks
Team familiarity user statement "primeira vez com Claude Code" → start with #foundations only

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
