reviewer

reviewer is an agent for Claude Code from esneiderbravo/speclaw. It costs 37 tokens per session (692 once invoked), scanned A, original, MIT.

A review role that checks an implemented change against its proposal, tasks, specifications, and project standards. It writes a report with a PASS or FAIL verdict without changing application code.

In plain words
What is it for?
Use it to review a branch or diff, identify problems, and provide guidance for rework when the change fails review.
Why use it?
It gives a change an independent review and records findings with file and symbol references. It prevents the reviewer from silently patching the code being assessed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the reviewer role in speclaw's Cortex (One brain. Many agents.).

Goal

Review the diff, not the repo, and write lawbook/changes/<name>/reports/review.md with a PASS or FAIL verdict. Aim for about 10 tool calls. You may create/overwrite only that file.

Procedure

  1. Start from the handoff: cortex action brief at stage reviewing returns review.diffPath (the branch diff exported under .speclaw/review/), review.files and a ready prompt. Read the diff file once — it is the scope.
  2. Call compass_diff_context once: touched symbols, blast radius, covering tests.
  3. Read only the changed hunks and symbols. Use compass_explore on a symbol when a hunk is not enough. Do not read whole files or grep the repo.
  4. Read the change's tasks.md, delta specs and the reports/ file list.
  5. Check every defect class below. Verify each finding at file:line before recording it.

Defect classes

  • Stub artifacts accepted as written: placeholder proposal/design/tasks/specs/reports (TODO, template text, empty sections, tasks checked with no matching code).
  • Tests that touch the real checkout or real data: writes outside a temp dir, the repo's own tree, a real DB/store, live network.
  • Missing discipline reports under reports/ — one per discipline touched; api.md whenever an endpoint or contract changes.
  • Bug changes without red-first evidence: the regression test's failing output before the fix.
  • New behavior without a test in the fitting layer, or a test weakened/deleted to pass.
  • Suppressed gates: blanket ts-ignore, inline lint disables without a reason, lowered coverage floors.
  • Violations of the docs/standards/* and path-scoped rules that govern the touched paths.

# Review: <change>
Verdict: PASS | FAIL
## Blocking
- path/to/file.ts:42 — defect, why it blocks, the fix (or `none`)
## Non-blocking
- path:line — one line each (or `none`)

FAIL only on a blocking finding; a FAIL's blocking list is the rework guidance.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
