# R005 Code Review — Step 2: Wire `Catalog()` into the registry

**Verdict:** Approve.

I reviewed `git diff c9448c0..HEAD`, with focus on `internal/tools/catalog.go`, `internal/tools/catalog_test.go`, and the `defaultRegistry.Register` refactor in `internal/tools/registry.go`.

## Findings

No blocking findings.

The current implementation addresses the previous Step 2 concerns:

- `Register` and `Catalog()` now share the same `registryBaseTools` enumeration for the base tool constructors.
- `Catalog()` builds an ungated metadata catalog with full delete/toolset capability and includes coach-mode plus the advanced-capabilities meta tool.
- Tier and safety are derived from tool metadata (`EffectiveToolset()` and `Requirement.effective()`), not from name heuristics.
- Group metadata is explicit and the tests reject missing/unknown groups.
- Registry parity, uniqueness, snake_case names, sort order, PRD registered-tool overlap, analyzer exclusions, and key summary behavior are covered by `catalog_test.go`.

## Checks run

- `go test ./internal/tools` — pass
- `golangci-lint run ./internal/tools` — pass
- `go test ./...` — pass
- `golangci-lint run ./...` — pass
