# R007 Code Review — Step 3: Generator binary

**Verdict:** Approve.

## Findings

No blocking findings.

## What I checked

- Reviewed the full diff from `9219a27..HEAD` and the changed files:
  - `cmd/gendocs/main.go`
  - `cmd/gendocs/main_test.go`
  - `cmd/gendocs/testdata/tools.golden.json`
  - `web/data/tools.json`
  - task status/review bookkeeping
- Confirmed `cmd/gendocs`:
  - parses `--out` with default `web/data/tools.json`;
  - rejects unexpected positional arguments;
  - calls `tools.Catalog()` as the sole production metadata source;
  - writes two-space indented JSON with a trailing newline;
  - writes via a temp file in the target directory and renames over the destination.
- Confirmed the golden test writes to a temp directory and compares against `cmd/gendocs/testdata/tools.golden.json`.
- Confirmed the committed `web/data/tools.json` matches current generator output.

## Commands run

```sh
git diff 9219a27..HEAD --name-only
git diff 9219a27..HEAD
go test ./cmd/gendocs ./internal/tools
go run ./cmd/gendocs --out /tmp/icuvisor-tools-test.json && diff -u web/data/tools.json /tmp/icuvisor-tools-test.json
go test ./...
```

All tests and generated-output checks passed.
