code-examination

code-examination is a skill for Claude Code, Codex from lubochka/xiigen-general-skills. It costs 25 tokens per session (169 once invoked), scanned A, original, Apache-2.0.

A code-reading guide for understanding a local codebase before making changes. It focuses on finding relevant files, reading nearby patterns and tests, and identifying interfaces and ownership boundaries.

In plain words
What is it for?
Use it before implementing features, refactoring, fixing tests, or changing architecture. It helps locate entry points, inspect related code, and verify that a proposed change fits the project.
Why use it?
It reduces the risk of changing code without understanding its existing contracts or conventions. It encourages small, compatible changes based on evidence from the repository.

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

code-examination 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 8d 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

Code Examination

Purpose

Understand local code before changing it.

When to Use

Use before implementation, refactoring, test fixes, or architecture changes.

Inputs

Entry points, neighboring files, tests, interfaces, naming conventions, ownership boundaries.

Steps

  1. Locate the relevant code path.
  2. Read nearby patterns and tests.
  3. Identify contracts and boundaries.
  4. Make the smallest compatible change.

Gates

The change matches local style and contracts.

Evidence

Relevant files read and patterns followed.

Anti-Patterns

Inventing a new abstraction without reading the codebase.

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.
