plan-review

plan-review is a command for Claude Code from andrei-isvoran96/claude-skill-lab. It costs 0 tokens per session (1,013 once invoked), scanned A, original, MIT.

A command that creates an implementation plan for a requested change and has separate planning reviewers check and revise it for up to three rounds. A plan review is a structured check of proposed files, design choices, and tests before coding.

In plain words
What is it for?
Use it when a task needs a reviewed step-by-step plan covering files, architecture, tradeoffs, tests, and open questions.
Why use it?
It can expose incorrect assumptions about the codebase and improve the plan before implementation begins.

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

plan-review 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 9d 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Draft an implementation plan for the user's request, then run up to 3 rounds of unbiased review by a fresh Plan subagent, revising between rounds.

The user's request: $ARGUMENTS

Procedure

Step 1 — Draft the initial plan

Spawn a Plan subagent to produce the first draft. Give it only the user's request above (no prior conversation). Ask for a step-by-step implementation plan: critical files, changes per file, architectural tradeoffs, test strategy, and any open questions.

Store the returned plan as PLAN_V1.

Step 2 — Round 1 review (always run)

Spawn a fresh Plan subagent as reviewer. It must not see your drafting reasoning or the parent conversation — only what you put in its prompt. CLAUDE.md is auto-loaded, so the reviewer already knows the architecture, commands, and coding standards.

The reviewer prompt must include:

  1. The user's original request (verbatim: $ARGUMENTS)

  2. The full plan text (PLAN_V1)

  3. Instruction to verify claims against the real code — Read/Grep the codebase to check that referenced files, services, and patterns actually exist and are the right home for the changes. Do not judge on vibes.

  4. Review rubric:

    • Correctness: will this actually solve the user's request?
    • Missing edge cases or error paths
    • Scope: anything added beyond what was asked? Anything required but missing?
    • Architectural fit: matches existing patterns?
    • Testability and test coverage
    • Adherence to the project's CLAUDE.md coding standards
  5. Required output contract — the reviewer MUST start its response with one of exactly two tokens on the first line:

    • APPROVED — no substantive issues, plan is ready to execute
    • NEEDS_CHANGES — followed by itemized issues (severity: critical/warning/nitpick, with file:line references where applicable)

    Nitpick-only findings still count as APPROVED — only critical/warning issues warrant NEEDS_CHANGES.

Step 3 — Decide whether to iterate

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.
