What problem does it solve? Keeping a local project plan in sync with a Trello board requires manually recreating every Goal as a card and every task as a checklist item, which is repetitive and error-prone. This Skill automates that push from .work/PLAN.md to Trello while avoiding duplicate cards on repeat runs. ## Core Features & Use Cases - Hierarchical Sync: Maps Goals to Trello cards, Micro-Goals to checklists, and Tasks to checklist items in the board's Back Log list. - Idempotent Operation: Skips Goals already tagged with [trello:CARD_ID] and annotates the plan file immediately after each card is created, so partial failures never cause duplicates. - Per-Project Board Resolution: Reads the target board from a .claude/trello-board file, a command argument, or an interactive prompt that can save the choice. - Use Case: After drafting a sprint plan in .work/PLAN.md with three Goals and their tasks, run the sync once to create all cards and checklists on your project board, then re-run it later to push only newly added Goals. ## Quick Start Ask the AI to run /sync-trello to push the Goals from .work/PLAN.md to your Trello board as cards with checklists.
