Planning GitHub Issues

Creates detailed implementation plans for GitHub issues by analyzing the codebase, breaking work into ordered tasks, and posting the plan as a comment on the issue.

Workflow

1. Read the issue using gh issue view <number>
2. Analyze the codebase — read all files referenced in the issue's Context section and any related files
3. Create the plan with ordered tasks, file changes, and test strategy
4. Post the plan as a comment on the issue using gh issue comment
5. Move the issue to "In Progress" on the project board if applicable

Plan Format

Every plan must follow this structure posted as an issue comment:
