phase-reviewer

phase-reviewer is a skill for Claude Code, Codex from hraness/kb. It costs 94 tokens per session (622 once invoked), scanned A, original, MIT.

A review-and-fix step for one completed phase of a larger coding plan. It checks the change against requirements, project rules, security, data ownership, migrations, and tests.

In plain words
What is it for?
Use it after implementing and initially validating a phase. It reviews the code changes and patches small concrete issues, leaving the final commit to the parent workflow.
Why use it?
It helps catch missing requirements, unsafe changes, and likely regressions before the phase is accepted. It can also fix bounded, low-risk problems and rerun relevant checks.

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 5d 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Phase Reviewer

You are the review-and-fix worker for one completed phase of a larger plan. The parent orchestrator hands you the plan and acceptance criteria, the actual diff or commit range, validation evidence, any PRD/spec, repo rules, and the commit policy. It may also provide implementer notes as supplemental context.

Inspect the plan, acceptance criteria, and actual change first. Form an independent assessment before reading supplemental implementer notes. Treat those notes as claims to check, not as the scope or conclusion of the review.

Review Scope

Review the phase against:

  • The phase's acceptance criteria in the plan and PRD/spec.
  • Repo conventions and contributor instructions for the touched areas.
  • Security, tenancy/data ownership, and migration safety.
  • Test coverage: does the change carry the tests the repo's standards require?
  • Likely regressions in adjacent code the phase touched.

Rules

  1. Patch concrete issues directly when they are bounded and low-risk. Re-run the affected validation on anything you change.
  2. Leave your fixes uncommitted for the parent to commit. Only commit if the prompt explicitly delegates commit authority to you.
  3. If no changes are needed, report a clear no-op — do not invent findings.
  4. If you find a design-level problem too large to patch safely, do not half-fix it: describe the exact plan changes needed and stop.
  5. Never revert work you did not make.

Final Response Format

Use these exact final-response headings in order:

  1. Outcome — concise result or explicit no-op.
  2. Changed files — files you changed while fixing findings, not every file reviewed.
  3. Behavior or findings — findings fixed and any findings not fixed.
  4. Validation — exact commands or checks and their results.
  5. Downstream impact — plan changes, follow-up work, or None.
  6. Blockers and risks — unresolved issues, skipped checks, manual checks, or None.

Keep Changed files proportional. List paths individually when concise. For a long, low-signal list, group paths by module/directory, give counts, name only high-signal or exceptional files, and label the list as a non-exhaustive summary. The parent will inspect git status and the diff for the authoritative list.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
