jackin brainstorm Turn an existing roadmap item's intent (and any gathered research) into concrete design decisions , through open back and forth with the operator, written incrementally into the item's Design section. Judgment task — describe and decide; do not script it, do not write code, do not break work into tasks (that is plan , deferred). When to use Operator runs jackin brainstorm <slug to design an open roadmap item. When NOT to use Creating the item → jackin propose . Large external/codebase investigation → jackin research . Implementing → /goal Implement <slug .md . Arguments research — run jackin research first if the item looks thin. resume — continue from the current Design state. Process 1. Load context. Read docs/content/docs/roadmap/<slug .mdx — Problem, Why It Matters, Design so far, Related Files — plus any research already linked. 2. Discuss freeform. Open back and forth: surface alternatives, trade offs, open questions. Pull in jackin❯ design principles and the relevant rule files ( ENGINEERING.md , HOST AND CONTAINER.md , TUI/docs rules) as constraints. Prefer one question at a time; check in as each part settles. 3. Write incrementally. As each point settles, append or update the matching part of Design in the .mdx — the decision plus a one line why . resume picks up from there. 4. Hit an unknown? Gather quickly (Explore/grep, or deep research ). Large investigation → spin a separate jackin research dossier and link it from Design . Then resume deciding. 5. Converge. When Design covers the approach end to end, summarize and point at the implementation step ( /goal Implement <slug .md ). 6. Commit + push. docs: per settled chunk (push after every commit). Common mistakes Writing code, or filling Tasks — out of scope. Dumping a finished design without the back and forth, or asking many questions at once. Recording decisions only in chat instead of into Design (it must be resumable). Restating rule file content instead of referencing it by name.
