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 | $0.03948 | $0.03948 |
| Opus 5 | $0.01974 | $0.01974 |
| Sonnet 5 | $0.00790 | $0.00790 |
| Haiku 4.5 | $0.00395 | $0.00395 |
Grade A, and why
hevy-mcp 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 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.
This is a copy
94% identical to hevy-mcp copilot-instructions.md — 81 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Agent Instructions for hevy-mcp
ALWAYS follow these instructions first and only fallback to search or additional context if the information here is incomplete or found to be in error.
Project Overview
- hevy-mcp is a Model Context Protocol (MCP) server for the Hevy Fitness API, enabling AI agents to manage workouts, routines, exercise templates, and folders via the Hevy API.
- The codebase is TypeScript (Node.js v24+), with a clear separation between tool implementations (
src/tools/), generated API clients (src/generated/), and utility logic (src/utils/). - API client code is generated from the OpenAPI spec using Kubb. Do not manually edit generated files.
- Type Safety: The project uses Zod schema inference for type-safe tool parameters, eliminating manual type assertions and ensuring compile-time type safety.
- MCP SDK internals sensitivity:
src/utils/stdio-observability.tsdepends on MCP SDK stdio internals (private fields such as_ondata/_readBuffer) for raw chunk instrumentation. Re-run the stdio observability test suite after any@modelcontextprotocol/sdkupgrade.
Git & Workflow Standards
- Conventional Commits: AI agents (such as Claude Code, Antigravity, etc.) and developers must always use the conventional commit format (e.g.,
feat:,fix:,refactor:,build:,ci:,chore:,docs:,style:,test:) for all commits they generate or suggest. - No Direct Pushes to
main(CRITICAL): Pushing directly to themainbranch is strictly prohibited and blocked by branch protection. All development must be done on feature branches (e.g.,feat/some-featureorfix/some-bug) and submitted via a Pull Request. - Changesets (CRITICAL): The project uses Changesets for versioning and releases.
- RELEASE CADENCE: Merge the automated
changeset-release/main("Version Packages") Pull Request on a regular cadence (weekly is the default), not via ad-hoc frequent merges. - URGENT EXCEPTION: Security fixes and high-impact user-facing bug fixes may be released immediately outside the routine cadence.
- WHEN TO USE: Every single PR/change that modifies source code or package dependencies MUST include a changeset file.
- HOW TO CREATE BUMP CHANGESETS: Use
npx changesetwithpatch/minor/majoronly for user-facing, runtime-visible changes. - NO-OP / NO-RELEASE CHANGES: For docs, CI config, internal tests, refactoring, and other internal-only changes, you MUST run
npx changeset --empty. - CI ENFORCEMENT: Pull Requests are guarded by a CI check that runs
npm run check:changeset(which runsnpx changeset status --since=origin/<base_branch>). CI will fail if no changeset file is staged/committed. - VALIDATION: You can validate your changeset status locally by running
npm run check:changeset. Make sure the changeset file is staged/committed.
- RELEASE CADENCE: Merge the automated
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.
