# Review R011 — Code review for Step 2

Verdict: **ACCEPT**

Reviewed changes from `5bfaca8..HEAD`:

- `scripts/benchmark/kr5_benchmark.py`
- `scripts/benchmark/prompts/kr5_shared_prompts.json`
- `scripts/benchmark/testdata/fixtures/icuvisor-analyzer-family.json`
- `taskplane-tasks/TP-100-analyzer-benchmark-harness/STATUS.md`
- prior Step 2 reviews R009/R010

Verification run:

- `python3 -m py_compile scripts/benchmark/kr5_benchmark.py`
- `python3 -m json.tool scripts/benchmark/prompts/kr5_shared_prompts.json >/dev/null`
- `python3 -m json.tool scripts/benchmark/testdata/fixtures/icuvisor-analyzer-family.json >/dev/null`
- `python3 scripts/benchmark/kr5_benchmark.py --mode fixtures --prompt-set scripts/benchmark/prompts/kr5_shared_prompts.json --fixture-dir scripts/benchmark/testdata/fixtures --output /tmp/kr5-step2.json --allow-approx-tokenizer --generated-at 2026-05-20T00:00:00Z`

The prior R010 blocker is addressed: the analyzer-enabled fixture catalog now includes the full analyzer-family set used by the harness classifier (`analyze_*`, `compute_*`, `get_activity_histogram`, and `get_fitness_projection`) with non-stub descriptions and input schemas, while the disabled and enabled non-analyzer catalog payloads remain byte-identical under the harness canonical comparison.

The Step 2 implementation also satisfies the requested prompt-shape work:

- analyzer-only prompts are scoped with `server_scope: ["icuvisor-analyzer-family"]`, so legacy/reference fixtures are not forced to add synthetic analyzer coverage;
- each analyzer prompt has explicit enabled/disabled `expected_tools_by_mode` rows;
- `expected_source_tools_by_mode` is count-capable and is validated against fixture call rows;
- the fixture run passes and reports the expected analyzer contrast (`analyzers_enabled` has zero LLM-visible raw stream pulls; `analyzers_disabled` has three).

## Non-blocking notes

- `STATUS.md` still has the small bookkeeping mismatch from R010: the review table records R009 as `ACCEPT`, but the execution log line says `Review R009 | plan Step 2: REVISE`. Please correct it during the next status update.
- A future hardening step could make the fixture validation assert the complete analyzer-family catalog for `icuvisor-analyzer-family`, not just the analyzer tools exercised by the new prompts. The current fixture is correct, but the harness would not currently catch a later removal of an unused analyzer-family tool such as `analyze_distribution`.
