wallfacer CLAUDE.md

wallfacer CLAUDE.md is an instructions file for coding agents from changkun/wallfacer. It costs 133 tokens per session, scanned A, original, MIT.

Project instructions that require bug fixes to include a reproducible test, encourage small frequent commits, and set rules for specifications, documentation, comments, and cleanup.

In plain words
What is it for?
They are for guiding tests, commits, feature planning, project-file discovery, documentation tone, and code-comment style.
Why use it?
They give coding work a consistent process and make bug fixes easier to verify and review.

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

wallfacer 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

If you didn't add a test, you didn't fix a bug. Every bug fix must include a reproducible test that fails without the fix and passes with it. You commit frequently, one small scope diff at a time. Push to main once a full batch of work is complete and verified. Leftover must be cleaned up using follow up commits. When working on a big feature, create specs first then start implementing. Relevant latere projects and shared components and packages can be found in ../ When writing user facing docs, use audience language and neutral tone. Avoid using first person and second person pronouns. Code comments and internal tech docs are precise and deep depth.

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.
