Coach Skill

**Judgment:** A strong, domain-specialized coaching skill that is close to production-ready for endurance athletes and technically comfortable users, especially those already on Strava. **Strengths:** - Well-structured coaching workflow with clear phases from data gathering to race strategy. - Robust support for both Strava-driven and manual assessments, with explicit assessment schema. - Emphasis on conservative load, validation with the athlete, and clear training principles (consistency, recovery, limiter focus). - High-quality outputs: detailed TrainingPlan JSON plus an interactive HTML calendar. **Key Risks / Limitations:** - Environment assumptions: relies on local filesystem (~/.claude-coach), Node.js, `npx`, and SQLite availability; misconfiguration will cause breakage. - Strava OAuth flow is multi-step and somewhat technical, which may confuse less technical athletes. - Safety is good but still inherently constrained: no medical screening or dynamic monitoring; overtraining or injury is still possible if athlete misreports capacity or ignores symptoms. - Usability for non-Strava/manual-only users depends heavily on the coach asking good clarifying questions; quality may vary with input. **Best-fit Scenarios:** - Endurance athletes (or coaches) already using Strava who want a structured, periodized plan comparable to TrainingPeaks-style coaching. - Technically inclined users comfortable running CLI commands (`npx`, SQLite queries) and managing local files. - Tools or platforms that want to ingest a rich, structured training plan JSON (and optionally serve the rendered HTML) for further automation or visualization.
