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 | $0.00318 | $0.00318 |
| Opus 5 | $0.00159 | $0.00159 |
| Sonnet 5 | $0.00064 | $0.00064 |
| Haiku 4.5 | $0.00032 | $0.00032 |
Grade A, and why
hevy-mcp copilot-instructions.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 8d 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.
What it actually says
Copilot instructions
The full instructions for this repository are in AGENTS.md at the repo
root. Read it before making changes. Several directories add local rules in their own
AGENTS.md — src/hevy/, src/engine/ and src/auth/.
The essentials, so that a short session does not go wrong before it gets there:
- Package manager is yarn classic (v1). Never npm, npx or pnpm.
- Validate every change with
yarn typecheck && yarn test && yarn build. There is no linter;yarn lintdoes not exist. - Local imports need the
.jsextension (./tools/read.js) — the project is ESM withmoduleResolution: NodeNext. - Never add a tool that writes workout history. The server reads history and writes
only routines. That guarantee is published to users in
docs/CONNECTOR.md. - Never log an API key, token or sealing key.
- Hevy's API has no DELETE, so failed writes are never retried and writes resolve every name before sending anything.
- All arithmetic belongs in
src/engine/as pure, fixture-tested functions. The server computes the numbers; the model interprets them. - Add a changeset (
yarn changeset) for any user-facing change, and never commit tomaindirectly.
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.
