scrutinize

scrutinize is a skill for Claude Code from pitimon/8-habit-ai-dev. It costs 117 tokens per session (3,122 once invoked), scanned A, original, MIT.

An independent review of a software plan, pull request, or proposed change that checks the underlying goal and follows the real code path from start to finish.

In plain words
What is it for?
Use it before committing to an implementation approach or merging a pull request, alongside a normal security and quality review.
Why use it?
It can reveal that a change is unnecessary, too broad, or incomplete even when the changed lines look correct.

Written for Claude Code: allowed-tools in frontmatter. Also seen: reads .claude/ paths.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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 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.

Scrutinize (มองจากภายนอก แล้วไล่ทางจริง)

Habit: H5 — Seek First to Understand + H8 — Find Your Voice | Anti-pattern: Rubber-stamp "LGTM" reviews that only check what's already in the diff

Stand outside the change and ask whether it should exist at all, then verify it actually does what it claims end-to-end. Different from /review-ai: that skill checks security/quality/perf on the diff. This skill questions scope, traces the call graph, and surfaces whether a simpler alternative was missed.

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. Follow the call graph through real code paths.
  • Actionable, concise, with rationale. Every finding states what to change, why, and what evidence led you there. No filler, no restating the diff back.

When to Use

  • Before committing to an implementation approach (after /design or /build-brief, before code is written).
  • Before merging a PR — as a second pass alongside /review-ai.
  • When a plan or design doc feels "fine" but you want an independent check.
  • When the user says "scrutinize", "sanity-check", "second opinion", "outsider review", "audit this approach".

When to Skip

  • Auto-generated formatting changes (lint --fix, prettier) — nothing to question.
  • Dependency version bumps with passing CI and no API surface change.
  • Reverting a commit to its exact previous state.
  • Single-line typo fixes.

Workflow — Run in Order, Do Not Skip Ahead

1. Intent — what is this actually trying to do?

  • 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, smaller, or more elegant way to achieve the same goal? Consider:
    • Doing nothing (is the problem real / load-bearing?).
    • Using something that already exists in the codebase instead of adding new surface.
    • A smaller change that solves 90% of the goal with 10% of the risk.
    • Solving it at a different layer (config vs code, framework vs app, build vs runtime).
  • If a better alternative exists, name it explicitly with rationale. This is the most valuable thing you can output — surface it before the line-by-line review.
  • When you reject an alternative (or judge the current approach a trap), first state its strongest case (steelman), then tag why even that best case fails — hidden cost / false economy / scaling failure / premature abstraction (commandment 14, integrity-principles.md).

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.

scrutinize is a skill published in the GitHub repository pitimon/8-habit-ai-dev (3 stars, last pushed 1mo ago), licensed MIT. It adds 117 tokens to every session and 3,122 once invoked, about $0.0006 per session on Opus 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.
