What is coros-training-mcp CLAUDE.md?

A project instruction file for a COROS connector, where COROS is a fitness platform for workout and health data. It describes a fork intended to support editable scheduled running workouts.

Use it when developing the connector, especially for scheduled running workouts, workout variables such as pace or distance, date changes, authentication, daily metrics, sleep, HRV, and activities.

It clarifies the project's direction, supported data, boundaries, and implementation priorities for agents working on the code.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01267	$0.01267
Opus 5.5	$0.00507	$0.00507
Sonnet 5.5	$0.00253	$0.00253
Haiku 4.5	$0.00127	$0.00127

Security

Grade A, and why

coros-training-mcp 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.

COROS MCP Fork Plan

This repository is a local fork of cygnusb/coros-mcp intended to become a running-first, editable COROS MCP rather than a mostly read-only metrics/workout wrapper.

Actionable implementation tasks live in TODOS.md. Terminology for library workouts, scheduled entries, and plan containers lives in docs/workout-taxonomy.md.

Goals

Support first-class editing of scheduled running workouts.
Support running workout variables such as distance, pace, repeats, rest, and date changes.
Keep the MCP tool surface small and stable.
Hide sport-specific payload complexity behind a unified workout schema.
Preserve compatibility with upstream where it does not fight the fork's direction.

Non-Goals

Do not keep separate user-facing tool families for bike, run, and strength unless the backend makes a unified tool impossible.
Do not store raw account credentials in repo files.
Do not promise post-workout strength result logging until the write endpoint is verified.

Current State

The upstream project already supports:

Web and mobile auth against unofficial COROS endpoints
Daily metrics, sleep, HRV, activities
Workout creation and deletion
Schedule listing, schedule add, and schedule remove
Strength workout creation from the COROS exercise catalogue

The main gap is that workout creation is currently shaped around time-based, power-oriented workouts and does not expose a generic edit path for running workouts.

Product Direction

The fork should present a small set of MCP tools:

list_workouts
get_workout
create_run_workout
update_run_workout
create_bike_workout
update_bike_workout
create_workout as a compatibility path for simpler non-running construction
update_workout as the lower-level clone-and-patch primitive
delete_workout
list_scheduled_workouts
move_scheduled_workout
replace_scheduled_workout

Optional later tools:

clone_workout
log_strength_results
list_activity_results

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.
