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 | $0.00619 | $0.00619 |
| Opus 5.5 | $0.00248 | $0.00248 |
| Sonnet 5.5 | $0.00124 | $0.00124 |
| Haiku 4.5 | $0.00062 | $0.00062 |
Grade A, and why
hads 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.

HADS — Human-AI Document Standard
Version 1.0.0 · Open Standard · 2026-03-26 · HADS 1.0.0
AI READING INSTRUCTION
Read [SPEC] blocks for authoritative facts. SPEC.md je kompletna specifikacija.
1. Što je HADS
[SPEC] HADS je tagging konvencija za Markdown tehničku dokumentaciju. Cilj: AI modeli mogu brzo identificirati što je autoritativna činjenica vs. narativ.
Četiri taga: [SPEC] (fakti), [NOTE] (kontekst), [BUG] (poznati bugovi), [?] (neverificirano)
Svaki HADS dokument mora imati AI manifest koji govori modelu što čitati.
[NOTE] HADS ne izmišlja novi format — koristi standardni Markdown. Zero adoption friction.

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.
- 2mo ago First seen · 84 lines · 619 tokens per session scan A 545001d30808
hads CLAUDE.md is an instructions file published in the GitHub repository catcam/hads (28 stars, last pushed 4mo ago), licensed MIT. It adds 619 tokens to every session, about $0.0025 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 2026-08-30.
