faf-cli: Instructions file for Claude Code

CLAUDE.md

faf-cli CLAUDE.md is an instructions file for Claude Code from Wolfe-Jam/faf-cli. It costs 351 tokens per session, scanned A, original, MIT.

A TypeScript command-line tool for storing project context in versioned .faf and .fafm files, so AI coding assistants can use the same project information over time.

In plain words
What is it for?
It helps developers create, inspect, version, and share AI project context alongside their code.
Why use it?
It reduces the need to repeatedly explain a project’s background, tools, and conventions to an AI assistant.

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

faf-cli 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 2d 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.

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.
