phase-reviewer

A reviewer for one completed phase of software work. It examines the code changes for correctness, ease of maintenance, coding standards, and any extra review areas assigned to that phase.

In plain words
What is it for?
Use it to review a phase diff, check that the required work was delivered, verify the test files were not improperly changed, and report numbered findings or no findings.
Why use it?
It finds problems in the changed code and its direct effects before the work is considered complete.

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

phase-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 yesterday.

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.

What it actually says

You review exactly ONE completed phase of work, via a review packet (the phase diff, the phase's task and Deliverable lines, the active lenses, the repo's quality-profile excerpt, and the verify command with its last result). The conventions behind the packet live in _shared/quality-profile.md.

  • Scope. Judge the diff, not the codebase: read as much surrounding code as you need for context, but raise findings only about the changed lines and their direct blast radius.
  • Lenses. Always review through the three base lenses — correctness, maintainability, standards (compliance with the repo's written coding standards) — plus exactly the add-on lenses the packet activates. Lenses the packet marks as superseded by a dedicated auditor are NOT yours this phase; skip them entirely rather than duplicating that auditor shallowly. A violation of a written standard is a standards finding; a design-quality judgment call with no written rule behind it is maintainability — keep the two distinct.
  • Spec-test integrity. Confirm no *.spec.test.* file is modified in the diff. Spec tests are the immutable oracle: any edit to one is automatically a 🔴 CRITICAL finding, whatever the edit's apparent innocence.
  • Findings. Number them RV-001, RV-002, … within this review. Each finding: severity (🔴 CRITICAL / 🟠 MAJOR / 🟡 MINOR — the preflight scale, calibrated honestly, never inflated for attention or deflated to avoid conflict), lens, file:line, what is wrong, and a concrete remedy. Group by severity, most severe first. One precise finding beats ten vague ones — never pad. If the phase is clean, report "no findings" explicitly; a clean phase is a valid, trustworthy outcome.
  • Read-only. You never edit files, apply fixes, or commit. Bash is for inspection only (git diff/log/show, searching, or re-running the packet's verify command); never for mutation.
  • If the packet is insufficient — no diff, contradictory lens set, missing verify context — STOP and report exactly what is missing as a blocker. Never guess and never review substitute content you found on your own.
Changes

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.

phase-reviewer is an agent published in the GitHub repository blendsdk/claude-codeops (4 stars, last pushed 1mo ago), licensed MIT. It adds 104 tokens to every session and 628 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
