FreeReps: Instructions file for Claude Code

CLAUDE.md

FreeReps CLAUDE.md is an instructions file for Claude Code from meltforce/FreeReps. It costs 2,155 tokens per session, scanned A, original, MIT.

A project guide for FreeReps, a self-hosted health-data server and dashboard that imports data from health and fitness apps. The project also includes an iPhone companion app and an MCP server, and is organized as a monorepo, meaning multiple related parts share one repository.

In plain words
What is it for?
Use it when working on health-data imports, the Go server, the embedded web dashboard, the iPhone app, database formats, or API payloads.
Why use it?
It highlights important build requirements and warns that third-party data formats must follow the project’s specifications or records may be silently lost.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md.

This is meltforce/FreeReps's own configuration. It tells Claude Code how to work on FreeReps itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything FreeReps configures →

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

FreeReps 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 yesterday.

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 — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.

FreeReps

Self-hosted server for health data: ingest from Apple Health, Oura and Alpha Progression, storage in PostgreSQL/TimescaleDB, a web dashboard with freely configurable correlations, and an MCP server. It computes no scores and does no coaching — that is a decision, not a gap (DECISIONS.md).

Monorepo. server/ holds the Go binary freereps with the web UI embedded; app/ holds the iOS companion (FreeReps.xcodeproj). Build and run instructions, and the wire-format specs every ingest change starts from, live in server/CLAUDE.md and app/CLAUDE.md, which load only when working under those paths.

Gotchas

  • The backend does not compile without server/web/dist. server/web.go embeds it via go:embed. Build the frontend first, or create the stub: mkdir -p server/web/dist && touch server/web/dist/.gitkeep. Why: a missing directory fails the Go build with an embed error that names the directive, not the cause.

  • A metric arriving from two sources needs a unit decision and a source filter. Apple Health and Oura disagree on both units and granularity. Why: both classes of failure have already occurred and neither raised an error — see the 2026-03-25 and 2026-03-26 entries in INCIDENTS.md.

  • What you learn about building or running goes into the CLAUDE.md next to the code, not into this file. Why: server/ and app/ instructions load only for sessions working there; in this file they would load in every session.

Repository & CI/CD

Forgejo is the source of truth: git.coydog-fence.ts.net/meltforce.net/freereps (origin). github.com/meltforce/FreeReps is a push mirror — never push there directly. The mirror is git push --mirror: it force-pushes and prunes refs that don't exist on Forgejo, so anything that must survive on GitHub has to exist on Forgejo first (a GitHub-only branch is deleted at the next sync).

Where What runs Triggered by
.forgejo/workflows/ci.yml Go build/vet/test/lint, frontend tsc + build, document contract check, then build → git.coydog-fence.ts.net/meltforce.net/freereps:edge → redeploy on smokey (the homelab VM shared by the in-house tsnet apps; freereps-lxc until 2026-11-04) push/PR on main
.github/workflows/ios.yml Xcode build (no macOS runner exists on Forgejo) mirror push
.github/workflows/release.yml Docker Hub image + GitHub Release with freereps-upload binaries tag push, carried over by the mirror

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.
