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 | $0.02814 | $0.02814 |
| Opus 5 | $0.01407 | $0.01407 |
| Sonnet 5 | $0.00563 | $0.00563 |
| Haiku 4.5 | $0.00281 | $0.00281 |
Grade A, and why
math-research-harness AGENTS.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 10d 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 — 258 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Session contract
This repository demonstrates owner-directed research using fictional content. Infer scope and authorization from ordinary conversation. Do not ask the owner to operate the harness as a configuration system.
Boot
Read this file first and classify the task.
- Meta or repository work needs no fictional thread state.
- For mathematical work, read
STEERING.mdand the relevantthreads/<thread>/LEDGER.md. Readdocs/PROJECT-FOUNDATIONS.mdonly when the ledger cites it, the task genuinely spans several threads, or one of its shared conventions is load-bearing; use it then without rederiving its contents or presenting them as new. - Read
threads/INDEX.mdonly when the thread is unclear or the task concerns the thread directory. - Follow ledger citations only as the task needs them. Do not load every note or claim by default.
- For literature work, also read
docs/LITERATURE.md. - For a durable computation or counterexample, read
docs/COMPUTATIONS.md. - For collaboration with agents lacking repository access, read
docs/COLLABORATION.md. - Read
docs/CAMPAIGN-CONTRACT.mdbefore an exact full-resolution campaign. - Read
docs/REPORTS.mdbefore producing a substantial owner-facing report. - Before drafting or revising a live research-paper manuscript, use
write-research-paperand readdocs/PAPER-WRITING.mdfor this repository's local overlay. - Before supervising a first-reader review, read
docs/FIRST-READER-REVIEW.md; the isolated reader loads the portable protocol throughread-research-paper. - Before supervising a skeptical-editor review, read
docs/SKEPTICAL-EDITOR-REVIEW.md; the isolated editor loads the portable protocol throughread-research-paper.
The portable write-research-paper and read-research-paper skills are
maintained outside this repository and installed through user-level skill
links; see docs/SKILLS.md. This repository keeps only its local overlays and
vocabulary tooling. A skill supplements this contract and never creates edit
authority. Other repository record shapes are in templates/.
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.

math-research-harness AGENTS.md is an instructions file published in the GitHub repository haruhisa-enomoto/math-research-harness (11 stars, last pushed 11d ago), licensed MIT. It adds 2,814 tokens to every session, about $0.0141 per session on Opus 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.
