module-analysis

module-analysis is a skill for Claude Code, Codex from cintia09/CodeNook. It costs 2 tokens per session (342 once invoked), scanned A, original, MIT.

A template for creating a module-analysis skill: instructions for examining one software module, service, or subsystem using its code, logs, documentation, and known behaviours.

In plain words
What is it for?
Use it to author analysis instructions covering a module’s normal flow, error handling, retries, known issues, review checks, and verification steps.
Why use it?
It provides a repeatable structure for investigating components with special log patterns, state changes, recurring bugs, or review requirements.

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

module-analysis 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 2mo 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.

What it actually says

Module Analysis Skill Template

Use this template to author a domain-specific analysis skill for a module, service, component, or subsystem.

When to author one

Create a per-module analysis skill when a module has:

  • log-prefix conventions or signature patterns;
  • a non-trivial state machine;
  • recurring known-issue fingerprints;
  • module-specific review or verification criteria.

Directory layout

Place each new skill in one of:

  • .codenook/memory/skills/<module>-analysis/SKILL.md for deployment-specific or team-specific skills;
  • <plugin>/skills/<module>-analysis/SKILL.md only when the skill is generic enough to ship with a plugin.

Frontmatter contract

id: "<slug>"
name: "<slug>"
title: "<Human title>"
summary: "<one-paragraph purpose>"
tags:
  - "skill"
  - "<module>"
  - "analysis"

Do not add unsupported frontmatter fields.

Recommended body sections

  1. Module overview.
  2. Log patterns.
  3. State machine / normal flow.
  4. Error handling and retry semantics.
  5. Known issues and fingerprints.
  6. Review checklist.
  7. Verification checks.

Every claim should be traceable to code, logs, documentation, or a completed case record.

Changes

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.
