# R006 code review — Step 2: Create MCPB packaging assets

Verdict: APPROVE

I reviewed the diff from `6734aab..HEAD`, read the changed packaging assets and task status, and re-ran the relevant packaging validations.

Validation run:

- `python3 -m json.tool packaging/mcpb/manifest.json` passes.
- `npx --yes @anthropic-ai/mcpb@latest validate packaging/mcpb/manifest.json` passes. The CLI only emits the non-blocking icon recommendation for 512×512 display size.
- `ICUVISOR_MCPB_PLATFORM=linux ICUVISOR_MCPB_OUTPUT=/tmp/icuvisor_linux_bad.mcpb scripts/package_mcpb.sh` now fails closed on the local Mach-O binary with: `ICUVISOR_MCPB_PLATFORM=linux requires an ELF icuvisor binary...`.
- `ICUVISOR_MCPB_OUTPUT=/tmp/icuvisor_test.mcpb scripts/package_mcpb.sh` succeeds and produces an archive containing only `manifest.json`, `server/icuvisor`, `assets/icon.png`, `README.md`, `LICENSE`, and `CHANGELOG.md`.

Findings:

- None blocking. The two R005 issues are addressed: the script validates binary format against `ICUVISOR_MCPB_PLATFORM`, and the manifest now advertises the registered `icuvisor_list_advanced_capabilities` tool name.

Notes:

- The MCPB CLI still recommends a 512×512 icon; the current 192×192 PNG validates and is acceptable for Step 2 unless the project wants a sharper installer icon before release.
