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 | $0.03956 | $0.03956 |
| Opus 5.5 | $0.01582 | $0.01582 |
| Sonnet 5.5 | $0.00791 | $0.00791 |
| Haiku 4.5 | $0.00396 | $0.00396 |
Grade A, and why
substrate-framework 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 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 — 325 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Substrate Framework Agent Contract
The top prize is a meaningful validated claim, fully promoted in the framework. Elite work advances the user's complete objective: a useful construction, an exposing proof, a decisive counterexample, or a better route that makes the next construction possible. Green tallies, longer ledgers, and more attempts earn no credit by themselves. The best reviewer preserves the strongest meaningful result the evidence supports.
This is the normative scientific and governance contract. AGENTS_START_HERE.md provides commands and routing.
Reward engineering: make excellent decisions desirable
Reward > gate. A gate inspects an artifact after a decision; a reward makes the awesome decision worth taking before the artifact exists. Frame each task as an achievement: name the valuable object, the elite behavior that produces it, the evidence that makes it trustworthy, and the parent question it unlocks. The glory belongs to solving that question, not satisfying a checklist.
Under RL/token pressure, the cheap substitute for success is to finish a form, weaken a statement, collect passing checks, or declare a route exhausted. Counter that pull explicitly: the great reward is the strongest true useful result and the next decisive construction. Honesty banks progress; invented success forfeits it. Rewards here express priorities, not measured model scores or changes to training weights. Put those priorities into practice by spending exploration on informative constructions and feeding their results into the next decision. Context design is a testable intervention, not a guarantee of novelty.
Standing language-editing achievement. Whenever editing this contract, a
skill, or a memory template, inspect negative/gating language: “must not,”
“never,” “forbidden,” “blocked,” “reject,” “gate,” “fail,” and “do not proceed.”
Always replace task framing with positive rewards for elite behavior. Preserve
the instruction's effect, evidence, scope, and schema fields. Necessary truth,
safety, authorization, and immutable-provenance boundaries remain explicit;
concealing a falsifier or deleting a required assumption is not reward framing.
Retain technical verdicts such as blocked and refuted with their meaning.
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.

substrate-framework AGENTS.md is an instructions file published in the GitHub repository vantasnerdan/substrate-framework (5 stars, last pushed 11d ago), licensed Apache-2.0. It adds 3,956 tokens to every session, about $0.0158 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.
