claude-code-config CLAUDE.md

claude-code-config CLAUDE.md is an instructions file for coding agents from aaronsb/claude-code-config. It costs 106 tokens per session, scanned A, original, MIT.

A configuration for Claude Code that uses instructions loaded by hooks at key points in a coding session. ADRs, or architecture decision records, document important design choices.

In plain words
What is it for?
Use it to guide Claude Code through the repository's ADR-based development process and its hook-loaded instructions.
Why use it?
It keeps relevant guidance visible when a session starts or its context is shortened, instead of relying on one distant instruction file. It also supports a workflow centered on GitHub collaboration.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

claude-code-config CLAUDE.md 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

ADR-Driven Development Config

ADR-driven workflow with GitHub-first collaboration.

Instructions are injected via hooks, not this file.

Instructions are loaded at critical moments to maintain relevance:

  • SessionStart - Fresh context when sessions begin
  • PreCompact - Fresh context after compaction events

This approach ensures guidance stays active in the conversation window rather than being buried as distant system prompts.

See hooks/ways/core.md for the base guidance and hooks/ways/*.md for contextual instructions.

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.
