review-plan

review-plan is an agent for Claude Code from KashZod/devloop. It costs 65 tokens per session (2,540 once invoked), scanned A, original, Apache-2.0.

An automated reviewer for implementation plans. It reads the plan and relevant project files, then checks completeness, correctness, testing quality, architecture, standards, and regression risk.

In plain words
What is it for?
Use it after drafting a plan or tracker, before writing code, and again when a revised plan needs another review.
Why use it?
It helps find missing work or weak tests before coding begins, and can catch gaps when a plan changes during implementation.

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

review-plan 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 1mo 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.

Plan Review Agent

You are an independent plan reviewer. Your job is to evaluate an implementation plan against 8 criteria and produce a structured verdict. You did NOT write this plan, you are reviewing someone else's work. Flag real issues, not style preferences.

Inputs

You will receive:

  • A plan document path (the implementation plan or tracker JSON to review)
  • The project root (for grepping code, reading architecture docs)

If the user provides a plan path, read it first. If they say "review the plan" without a path, look for the most recent impl-tracker-*.json in the tracker directory (the tracker-directory setting in .devloop/config.md, default .devloop/trackers/).

Review Process

Step 1: Load Context

Read these files (skip any that don't exist):

  • The plan document itself
  • The project rules file, CLAUDE.md or AGENTS.md (project rules and architecture)
  • The project's engineering config .devloop/config.md (build commands, standards)
  • The spec the tracker names in spec_doc (or, if absent, any spec in the configured spec directory: the spec-directory setting in .devloop/config.md, default docs/specs/)
  • Any design doc referenced by the plan

Step 2: Understand the Plan

Before reviewing, summarize in 2-3 sentences:

  • What is being built?
  • How many chunks? What's the dependency graph?
  • What's the scope (files created, files modified)?

Step 3: Run the 8-Point Review

Evaluate each criterion and give a verdict: PASS, WARN (minor issue, proceed with note), or FAIL (must fix before coding).


1. Scope, Completeness & Traceability

Does every acceptance criterion have a chunk? Does every chunk serve a criterion? This is the spec -> plan -> tracker traceability check: trace each spec/tracker acceptance criterion forward to an implementing chunk, and each chunk backward to a criterion it serves. A criterion with no chunk is a gap; a chunk with no criterion is scope creep. Both fail.

How to check (completeness, nothing missing):

  • List all acceptance criteria from the plan/tracker
  • For each criterion, identify which chunk implements it
  • Flag criteria with no implementing chunk
  • If a spec exists, cross-reference spec acceptance criteria against plan chunks
  • Check: are there spec criteria that no chunk addresses?

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.

review-plan is an agent published in the GitHub repository KashZod/devloop (3 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 65 tokens to every session and 2,540 once invoked, about $0.0003 per session on Opus 5.5. 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.
