What problem does it solve? Checking off dozens of completed tasks one by one in project planning files is slow and error-prone. This Skill batch-updates checkbox states in steps.md or tasks.md files so finished project work is reflected accurately in seconds. ## Core Features & Use Cases - Bulk Completion Modes: Complete all tasks, a specific section or phase, a custom range like "1-5,7,10-15", or pick tasks interactively. - Format Auto-Detection: Automatically finds steps.md (new format) or tasks.md (legacy format) inside a project's 01-planning folder. - Validated Writes: Re-reads the file after updating to confirm the new completion counts, with a --no-confirm flag for AI-driven automation. - Use Case: After finishing Phase 2 of a project, run one command to mark every task in that phase complete instead of editing 20 checkboxes manually. ## Quick Start Ask the AI to bulk complete all tasks in project 01 using the bulk-complete script with the --all and --no-confirm flags.
