What problem does it solve? Turning a ticket or task description into a concrete, actionable implementation plan is time-consuming and inconsistent across sessions. This Skill standardizes the plan phase by resolving the task source, applying a shared plan template, and saving the result as a properly named artifact. ## Core Features & Use Cases - Flexible task sources: Accepts an issue URL, shorthand reference like #99, a file path, or a free-form description of what to build. - Standardized plan output: Produces a plan with canonical YAML frontmatter and a shared implementation-plan template, identical to the plan phase of design-and-plan. - Context-aware saving: Saves the plan as a run artifact inside an active run or as a ticket-level artifact derived from session context, with timestamped naming conventions. - Use Case: Given a GitHub issue URL describing a migration task, generate a step-by-step implementation plan with risks and unknowns called out, saved to the ticket's artifact directory. ## Quick Start Ask the agent to create an implementation plan from issue #99 or from a description of the feature you want to build.
