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 | $0.00867 | $0.00867 |
| Opus 5.5 | $0.00347 | $0.00347 |
| Sonnet 5.5 | $0.00173 | $0.00173 |
| Haiku 4.5 | $0.00087 | $0.00087 |
Grade A, and why
archguardian 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
archguardian
Pre-commit hook and CLI that catches security issues, AI-generated code smells, naming convention violations, code duplication, architecture layer breaches, complexity metrics, dead code, IaC misconfigurations, and license compliance. Works with TypeScript, JavaScript, Python, Go, Rust, and Java.

Key conventions
- ESM-only (
"type": "module"in package.json), all imports use.jsextensions - Node >= 18 required
- AST parsing via ast-grep NAPI (native tree-sitter bindings, not WASM)
- Tests in
tests/unit/,tests/integration/,tests/e2e/using vitest - Config file:
.archguard.ymlvalidated with Zod schemas - Pipeline: analyzers run in parallel with 5s timeout each, findings are deduplicated, then suppressed, then optionally enhanced by LLM
- Monorepo support via
workspacesconfig with glob-based overrides
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.

archguardian CLAUDE.md is an instructions file published in the GitHub repository ysfAskri/archguardian (4 stars, last pushed 8mo ago), licensed MIT. It adds 867 tokens to every session, about $0.0035 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
