What problem does it solve? Athletes using AI assistants for coaching get generic advice because the assistant has no access to their actual training data, history, or goals. This Skill walks athletes through connecting their fitness providers (Intervals.icu, Hevy, Oura, Withings) to the WorkoutContext MCP, learns their training background through conversation, and builds personalized, data-grounded training plans stored as playbook NOTE events on their Intervals.icu calendar. ## Core Features & Use Cases - Guided provider onboarding: Checks connection status via setup_status, walks athletes through connecting Intervals.icu, Strava, Hevy, Oura, and Withings using single-use magic links, and verifies activity data sources are flowing. - Personalized playbook creation: Builds discipline-specific training playbooks (running, cycling, strength, or freeform for other sports) from Markdown templates, populated with zones, PRs, weekly structure, progression rules, and recovery guidelines derived from real API data and conversation. - Strength programming with Hevy integration: Creates Hevy routines seeded with working weights from actual workout history, pairs them with Intervals.icu calendar events, and configures RPE-based training load tracking. - Ongoing plan maintenance: Detects drift between playbooks and actual training, updates plans when routines or events change, and integrates Oura/Withings recovery signals into training rules. - Use Case: A runner who also lifts connects Intervals.icu and Hevy, shares their marathon goal and recent PRs, and receives a running playbook with pace zones plus a strength routine with real working weights — both synced to their calendar and watch. ## Quick Start Ask the assistant to help you get started with WorkoutContext and connect your Intervals.icu account to build your first training plan.
