What problem does it solve? It turns vague or specific fitness requests (fat loss, muscle gain, shaping, running, posture, pain boundaries) into executable Chinese training and diet plans, delivered as real Feishu online documents instead of plain chat advice. ## Core Features & Use Cases - Scenario-routed plan generation: A routing table maps user scenarios (beginner, canteen/takeout dieting, body shaping, strength, running, home workouts, pain/safety triage) to dedicated reference playbooks with training standards, exercise technique cards, and nutrition rules. - Feishu document delivery: Builds XML rich-text documents with whitelisted components (callout, grid, table, checkbox, bookmark), downloads verified real images locally, and inserts them at anchor positions via lark-cli media-insert. - Quality gate script: scripts/check_fitness_quality.py validates draft and final XML for structure, leaked internal fields, forbidden generated images, and content depth before delivery. - Use Case: A user says "I want to lose fat but only eat canteen food and can't count calories." The skill produces a Feishu doc with 211-plate ordering rules, sample meals, a light training plan, and weekly review metrics. ## Quick Start Ask the assistant to create a fitness plan for your goal, for example: "Use fitness-planner-pro to build an 8-week beginner fat-loss plan I can follow with home workouts and canteen meals, delivered as a Feishu document."
