What is arch-compiler CLAUDE.md?

Repository instructions for Architecture Compiler, a project that turns software architecture guidance into implementation work. They make AGENTS.md the main source of guidance.

Reading the repository's guidance, compiling or implementing architecture, and running the required preflight check.

They give the coding agent a defined place to find project rules and require a preflight check before architecture workflows.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00171	$0.00171
Opus 5.5	$0.00068	$0.00068
Sonnet 5.5	$0.00034	$0.00034

Security

Grade A, and why

arch-compiler 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 2mo 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

Agent Guide — Architecture Compiler

Claude should treat AGENTS.md as the canonical root guidance for this repo.

Read AGENTS.md first, then use:

skills/using-arch-compiler/SKILL.md if you need to choose the workflow
skills/compiling-architecture/SKILL.md to compile/finalise architecture
skills/implementing-architecture/SKILL.md to implement an approved architecture

Before compile or implement workflows, run the shared preflight helper when applicable:

~/.claude/arch-compiler/tools/archcompiler_preflight.py --app-repo <app-repo> --mode compile
~/.claude/arch-compiler/tools/archcompiler_preflight.py --app-repo <app-repo> --mode implement

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.
