# Code Review — Step 2: Snapshot every tool's argument schema

Decision: **APPROVE**

## Summary

The previous Step 2 blockers have been addressed. The live schemas for `get_activity_streams` and `get_activity_splits` now include descriptions/defaults for their arguments, the checked-in snapshots match the generator output, and the snapshot generator removes stale `*.json` files before writing the live registry set.

## Findings

No blocking findings.

## Verification run

- `tmp=$(mktemp -d); go run ./scripts/snapshot_tool_schemas.go -dir "$tmp" && diff -ru internal/tools/schema_snapshot "$tmp"; rc=$?; rm -rf "$tmp"; exit $rc`
- `tmp=$(mktemp -d); echo '{}' > "$tmp/stale.json"; go run ./scripts/snapshot_tool_schemas.go -dir "$tmp" >/dev/null; test ! -e "$tmp/stale.json"; rc=$?; rm -rf "$tmp"; exit $rc`
- `python3` check that every snapshot property has a `description`
- `go test ./internal/tools`
