related

related is a skill for Claude Code, Codex from FradSer/dotclaude. It costs 37 tokens per session (198 once invoked), scanned A, original, MIT.

A read-only Git-history tool that finds files and test suites that have often changed together with selected files.

In plain words
What is it for?
Use it before changing code or running tests to find historically coupled files and likely related test suites.
Why use it?
It reveals related code that may be affected by an edit, including tests that are easy to overlook.

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

related 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 4d 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

Execution

Execute git-agent related to query co-change relations (offline and read-only):

  1. Find coupled files:
    git-agent related <file-paths...>
    
  2. Find related tests:
    git-agent related --tests <file-paths...>
    
  3. Structured JSON output:
    git-agent related -o json <file-paths...>
    

Report the historically coupled files and tests to guide code edits and test suite execution.

CLI Reference: ../../references/cli.md

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.
