AI Fitness Coach Plugin

What's new

This release adds gc-coach — a Claude Code plugin that turns Claude into a
personalised fitness coach on top of your Garmin Connect data.

Plugin (install via Claude Code)

/plugin marketplace add ace4seven/GC-MCP
/plugin install gc-coach@gc-mcp-marketplace

5 slash commands: /coach-onboard, /coach-today, /coach-checkin,
/coach-plan-week, /coach-review

8 skills: coach-core, onboarding, daily-advisor, recovery-advisor,
pattern-detective, weekly-planner, endurance-block, strength-block

All coaching state is stored locally in ~/.gc-mcp/coach/ — no cloud sync.

New MCP tools (available without the plugin)

Tool	Description
coach_state	Read/write athlete profile, goals, weekly plan, daily log, flags, reviews
coach_log_subjective	Append a daily check-in (energy, soreness, sleep, RPE)
coach_compute_load_summary	7d/28d ACWR, trend, and per-modality load breakdown
coach_compute_readiness_synthesis	Composite readiness score + go_hard / moderate / easy / rest tier
