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 | $0.03230 | $0.03230 |
| Opus 5 | $0.01615 | $0.01615 |
| Sonnet 5 | $0.00646 | $0.00646 |
| Haiku 4.5 | $0.00323 | $0.00323 |
Grade D, and why
Bratan CLAUDE.md scanned grade D with 3 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 6d 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.
Sends data to an external URLmediumData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.
> 4. `curl -sf http://localhost:8005/api/corpus/search -d '{"query":"x","k":1}' -H "Content-Type: application/json"` — round-trip must return 200 (not 500), even with empty corpus Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
> 1. `rm -rf .chroma bratan.config.yaml` — disk wipe Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
> 1. `curl http://127.0.0.1:8000/api/health` → 200 + `{"ok":true}` The source is not reproduced here

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.

Bratan CLAUDE.md is an instructions file published in the GitHub repository AllanWessels/Bratan (2 stars, last pushed 1mo ago), with no licence file. It adds 3,230 tokens to every session, about $0.0161 per session on Opus 5. A static security scan graded it D with 3 findings (sends data to an external url, recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
