scrutinize

scrutinize is a skill for Claude Code, Codex from baphuongna/pi-crew. It costs 16 tokens per session (794 once invoked), scanned A, original, MIT.

A review approach that examines a change from an outsider’s viewpoint, first questioning whether it is needed and then tracing its claimed behavior through the code.

In plain words
What is it for?
Use it to review code changes end to end, compare simpler alternatives, and identify missing or incorrect behavior.
Why use it?
It helps catch unnecessary work and bugs that are hidden outside the changed lines. Findings include what to change, why, and the evidence behind them.

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

scrutinize 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 10d 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 — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Scrutinize

Stand outside the change and ask whether it should exist at all, then verify it actually does what it claims end-to-end.

Operating Stance

  • Outsider. Forget who wrote it and why they think it's right. Read the artifact cold.
  • End-to-end, not diff-local. The diff is the entry point, not the scope.
  • Actionable, concise, with rationale. Every finding states what to change, why, and what evidence led you there.

Workflow

1. Intent — Is this necessary?

  • State the goal in one sentence, in your own words. If you cannot, the artifact is underspecified — say so and stop.
  • Ask: Is there a simpler way?
    • Delete/does-nothing (is the problem real and load-bearing?)
    • Use existing code (does this already exist?)
    • Smaller change (solves 90% of goal with 10% of risk?)
    • Different layer (config vs code, framework vs app, build vs runtime?)
  • If a better alternative exists, name it BEFORE the line-by-line review.

2. Trace — Walk the actual code path

  • For each behavior the change claims, trace end-to-end through real code — not just the lines in the diff.
  • Include unchanged code on either side of the diff. Bugs hide at the seams.
  • Entry point → call sites → branches taken → state mutated → exit/return/side effect.

3. Verify — Does it do what it claims?

  • Does the traced code actually produce the behavior?
  • What inputs/states would break it? (Edge cases, concurrent callers, error paths, partial failures, retries, empty/null/unicode/huge inputs)
  • What does it silently change? (Performance, error semantics, observability, contracts)
  • How is it tested? (Do tests exercise the traced path, or pass while skipping it?)

4. Report

Format per finding:

[severity] file:line
Issue: ...
Impact: ...
Fix: ...

Severity:

  • critical: data loss, secret leak, arbitrary command/path escape
  • high: broken core workflow, ownership bypass
  • medium: regression, flaky behavior
  • low: polish, maintainability

Close with verdict: ship / fix-then-ship / rework / reject — with single biggest reason.

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.
