strict-reviewer

strict-reviewer is a skill for Claude Code from beingmartinbmc/jambavan. It costs 60 tokens per session (799 once invoked), scanned A, original, MIT.

A review guide for examining code diffs, pull requests, or other changes using a strict senior-engineer checklist. A diff is the recorded difference between two versions of files.

In plain words
What is it for?
Use it to inspect changed files, trace affected callers, check test coverage and risk flags, and report issues that a superficial review could miss.
Why use it?
It helps uncover root-cause problems, missing tests, unnecessary abstractions, and claims that have not been verified.

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

strict-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 12d 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 — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Strict Reviewer

Reviewing is not skimming for typos. Find what a lazy pass would miss: the wrong root cause, the abstraction nobody asked for, the claim with no evidence behind it.

Step 1 — Get the real diff, not a guess

If jambavan_review_pack is available, call it against the PR's base branch. It gives you touched files, parsed symbols changed or deleted in each, bounded extracted caller candidates, heuristic test associations/references, past failure records mentioning the same files, and risk flags (open // rin: debt, no matching test association). Treat graph and test associations as review leads, not proof of completeness.

Otherwise: git diff --stat first, then the full diff only for files that matter.

Step 2 — Root cause, not symptom

  • Is this a fix for the actual bug, or a patch on the path the ticket happened to name?
  • If a shared function was touched, were the relevant callers and public entry points checked? A guard added to one call site while an identified sibling caller stays broken is a review-blocking finding, not a nit.
  • Does the change explain why, not just what? A diff that only patches the symptom should be flagged even if it "works."

Step 3 — Scope discipline

Flag, don't just note, when a diff contains:

  • An abstraction with exactly one implementation (interface/factory for a single case).
  • A new dependency where the stdlib or an already-installed package would do.
  • Boilerplate or scaffolding nobody asked for.
  • Changes broader than the stated problem — "while I was in there" edits to unrelated code.
  • A shortcut with no // rin: marker naming its ceiling and upgrade path (or a // rin: marker used to excuse actual sloppiness rather than a conscious tradeoff).

Not negotiable, regardless of diff size: input validation at trust boundaries, error handling that prevents data loss, security, accessibility, and anything the original request explicitly asked for. A "small diff" is not an excuse to skip these.

Step 4 — Demand evidence, not assertions

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.
