About brainstorm
brainstorm is a jackin' development skill for turning an existing roadmap item's intent into documented design decisions through discussion. It updates the item's Design section incrementally and leaves task breakdown and implementation to later steps.
Key features
- 01Loads roadmap context and linked research
- 02Discusses alternatives and trade-offs
- 03Records decisions incrementally in Design
- 04Continues from existing design with --resume
- 05Commits and pushes settled design updates
Use cases
- 01Working through design choices for a roadmap item
- 02Documenting trade-offs and decisions for later work
- 03Resuming an unfinished design discussion

Details
From the project READMEbrainstorm
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-dev:brainstorm <slug>to design an open roadmap item.
When NOT to use
- Creating the item →
/jackin-dev:propose. - Large external/codebase investigation →
/jackin-dev:research. - Implementing →
/goal Implement <slug>.md.
Arguments
--research— run/jackin-dev:researchfirst if the item looks thin.--resume— continue from the current## Designstate.
Process
- Load context. Read
docs/content/docs/roadmap/<slug>.mdx— Problem, Why It Matters, Design-so-far, Related Files — plus any research already linked. - 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. - Write incrementally. As each point settles, append or update the matching part of
## Designin the.mdx— the decision plus a one-line why.--resumepicks up from there. - Hit an unknown? Gather quickly (Explore/grep, or
deep-research). Large investigation → spin a separate/jackin-dev:researchdossier and link it from## Design. Then resume deciding. - Converge. When
## Designcovers the approach end to end, summarize and point at the implementation step (/goal Implement <slug>.md). - 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.
