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:

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:

If signals are missing, ask 2–3 targeted questions BEFORE recommending. Never invent stack details.

Procedure

1. Read docs/registry/INDEX.md to enumerate available packs.
2. Score each pack against the project signals (stack match, domain match, compliance match, team-readiness fit).
3. Filter out packs whose When NOT to install matches the project shape.
4. Resolve conflicts using the Conflicts and overlaps section in each one-pager (pick one of overlapping packs based on context).
5. Order by priority: must-install → recommended → optional → skip-for-now.
6. Output a short recommendation table + rationale + install commands copied from each pack one-pager.
7. Defer install execution to the user (this skill never runs git clone / npm install itself).

Output format

## Registry recommendation for <project name>

Project signals detected:
- Stack: <e.g. Next.js + Supabase>
- Domain: <e.g. SaaS B2B compliance>
- Compliance: <e.g. LGPD>
- UI: <e.g. dashboard + landing>
- Public repo: <yes/no>

### Must install

| Pack | Why for this project | How |
|------|----------------------|-----|
| `<slug>` | <one sentence> | `<install command>` |

### Recommended

| Pack | Why | How |
|------|-----|-----|
| ... | ... | ... |

### Optional

| Pack | Why | How |
|------|-----|-----|
| ... | ... | ... |

### Skipped (and why)

- `<slug>` — <reason from `When NOT to install`>

### Open questions before installing

- ...

Rules

• Never invent packs. Only recommend slugs that exist in docs/registry/INDEX.md.
• Never install. Show the user the install command from the pack one-pager and stop.
• Cite the one-pager. Every recommendation links back to docs/registry/packs/<slug>.md.
• Never recommend archived packs.
• Flag missing license info. If a pack has License: check upstream, surface that as an open question.
• Re-run after changes. If the Technical Plan or Product Brief changes, re-invoke the skill.
• Respect the pass scope. In the design pass (stage 3.1), recommend only design-oriented packs and do not ask for the Product Brief, the Technical Plan, or the prototype — none of them exist yet.

Adding new packs

When the user says "encontrei um repo novo, adiciona aí":

1. Open the upstream URL.
2. Confirm license, status, and active maintenance.
3. Pick a slug (lowercase, hyphenated).
4. Create docs/registry/packs/<slug>.md from the template in docs/registry/README.md.
5. Add a row to docs/registry/INDEX.md.
6. Add the slug to relevant docs/registry/tags/<tag>.md files.
7. If the pack also influenced this OS itself, cross-link in UPSTREAM-SOURCES.md.
8. Re-run this skill against the current project to see if the new pack changes the recommendation.
