review-plan

review-plan is a skill for Claude Code from Rishi4792/compass. It costs 88 tokens per session (5,579 once invoked), scanned A, original, MIT.

A review step that tests a software plan from several angles before coding begins. It checks concerns such as dependencies, migration, security, testing, rollback, and possible effects on other parts of the project.

In plain words
What is it for?
Use it after creating a plan when you need structured checks of its assumptions, safety, tests, and likely impact.
Why use it?
It helps find gaps and risks in a plan before implementation makes them more expensive to fix.

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 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.

How it starts

The opening of the file, as written. The whole thing — 228 lines — stays where its author put it; the contents beside it link to each section on GitHub.

compass:review-plan (Review-2 · FULL)

Lens: will this plan, built exactly as written, work — and break nothing else?

Read these before you start. They are the standards this stage is held to, and they live in plugins/compass/shared/ so they are the same for every stage that uses them:

  • shared/review-core.md — the severity bug-bar, self-refutation and dedupe rules every review shares.

(A standard nobody loads is not a standard. shared/MANIFEST declares who reads each file and doctrine-wired-check.sh proves it — feynman.md sat unread for three releases while its own first line claimed three stages loaded it.)

Step 0a — the cheap checks run FIRST, before any reviewer is spawned

Run bash plugins/compass/scripts/mechanical-suite.sh . and read its output before doing anything else in this stage.

Why it comes first. The last release ran six independent adversarial reviews and they found 59 recorded defects. 32 of them — just over half — needed no judgment at all: a duplicate constant, a test whose population could be empty, a check nobody called, a shell mistake. A reasoning model was paid to find the fourth copy of a literal. The suite finds that whole class in seconds, for no tokens, and it runs before a reviewer is asked to look at anything.

What to do with it:

  • A MEASURED failure blocks this stage. Fix it and re-run. No reviewer should ever be handed a defect a script had already decided.
  • Its REPORTED lines are handed to the reviewers as context, not as findings — they are the things the suite could not decide, which is exactly where judgment is worth paying for.
  • If a reviewer finds a defect of a class the suite could have caught, ADD THE CLASS to plugins/compass/scripts/mechanical-suite-classes.md rather than re-reviewing it forever. That file is the registry; a class in it is a class no future review pays for twice.

Honest limit, stated so nobody over-trusts this. Only some defect classes are soundly mechanical — building this suite found that of five shell-trap classes exactly one could be decided by a line scan without failing on correct code. Every check therefore says whether it MEASURES or REPORTS. A green suite means the cheap classes are clear; it does not mean the work is right.

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.
