Commands

/jj-flow:plan

Start a planning session. Explores the codebase and creates a chain of TODO commits for the work described.

/jj-flow:plan add input validation to the API endpoints

/jj-flow:implement

Implement planned TODO commits. Works through each change in order — reading the plan, implementing it, verifying acceptance criteria, and updating the description.

# Implement all TODO descendants of the current change
/jj-flow:implement

# Implement a specific change by revset
/jj-flow:implement mq

# Implement a range of changes
/jj-flow:implement mq::vn

# Use a custom jj log command to select changes
/jj-flow:implement jj log -r 'descendants(@) & description("TODO:")'

Skill

The plugin includes the jj-flow skill which documents the full workflow convention — change description format, planning workflow, implementation steps, and completion checklist. The commands load this skill automatically.
