fitness-tools: Instructions file for Claude Code

CLAUDE.md

fitness-tools CLAUDE.md is an instructions file for Claude Code from almostjacked/fitness-tools. It costs 187 tokens per session, scanned A, original, MIT.

Project instructions for Claude Code in a fitness-calculator repository. They explain which guidance to read first and require a specification, plan, and implementation workflow for substantial changes.

In plain words
What is it for?
Use them when adding or changing fitness calculators, following the repository’s development workflow, or deciding how to handle changed outputs and tests.
Why use it?
They reduce the risk of changing public calculator results or reference values just to make tests pass. They also clarify where local design documents belong.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

fitness-tools 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.

What it actually says

CLAUDE.md

Read AGENTS.md first — it is the canonical guide to this repo (layout, setup, commands, the golden rules, and how to add a calculator). Everything there applies to Claude Code.

Claude-Code-specific notes

  • This repo uses the superpowers spec→plan→implement workflow. Design specs live in docs/superpowers/specs/ and implementation plans in docs/superpowers/plans/ (both are gitignored — local working docs). Before non-trivial work, brainstorm a spec, then write a plan, then implement task-by-task.
  • The two hardest-to-reverse rules are worth repeating: never change a pinned reference value to make a test pass, and a changed calculator output is a major version bump (outputs are the public contract).
Changes

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.
