Linear Brasa Brainstorm

Linear Brasa — Brainstorm (Design Document → Refined)

Take an existing brasa Linear issue and produce a reviewed design spec stored as a Document titled Design attached to the issue. Sequences brainstorm → grill → synthesize so the final artifact is adversarially stress-tested before being written.

Announce at start: "I'm using the linear-brasa-brainstorm skill to design WIL-X."

Always use the Linear MCP tools (mcp__plugin_linear_linear__*) — never gh or raw HTTP.

Workspace constants:

• Team: Wilsonfreitas — 6c3534b0-9f98-476c-a1d6-3f99119e9f88
• Project: brasa — 700095cc-dd63-405b-b285-1895aabce09d
• Labels: Idea · Bug · Improvement · Feature

Shared Convention A — Document upsert (never create duplicates)

MCP cannot delete a Document. Always upsert:

1. get_issue(id=WIL-X) → read documents: [{id, title}, ...]
2. Find the entry whose title EXACTLY equals "Design".
3. If found:      save_document(id=<that id>, content=<new content>)   # update in place
   If not found:  save_document(issue=WIL-X, title="Design", content=...)  # create once
4. NEVER call save_document(issue=...) when "Design" already exists in documents.

Shared Convention B — Status transition (read-back verified, never on abort)

1. Only after the skill's main work succeeded:
   save_issue(id=WIL-X, state="<Target>")   # state, NOT status
2. Read the returned JSON; confirm "status":"<Target>" before announcing.
3. If the skill aborts/errs before completing, do NOT move the status.

Phase 1 — Preconditions

1. Require the user to provide a WIL-X identifier. If missing, ask once: "Which issue? (e.g., WIL-42)".
2. Fetch the issue via mcp__plugin_linear_linear__get_issue. Read title, description, current label, and the documents array.
3. Look in documents for an entry with title exactly Design:
   • If found: call get_document(id=<that id>), show its content verbatim to the user, then ask: "Issue already has a Design Document. Re-brainstorm and overwrite it? (y/n)". Exit on decline.
   • If not found: proceed.
4. Briefly summarize the issue title + description (one or two sentences) so both of you share context.

Phase 2 — Brainstorm → Grill → Synthesize

2a — Brainstorm (diverge)

Invoke the superpowers:brainstorming skill. Follow its flow for exploration and candidate generation:

• Explore project context (files, docs, recent commits).
• Clarifying questions, one at a time.
• 2–3 candidate approaches with trade-offs and a recommendation.

Stop brainstorming before its "Write design doc" step. Do not write to docs/superpowers/specs/. The brainstorm's job ends when the user picks a candidate approach.

2b — Grill (stress-test)

Invoke the superpowers:grilling skill on the chosen approach. Grill adversarially — one question at a time — until both parties share a solid understanding of the design and its failure modes.

Grilling writes nothing. Its output is shared understanding only, not a document.

2c — Synthesis (mandatory write step)

After grilling, write the agreed design into the Design Document using Convention A:

1. Call get_issue(WIL-X) to get the current documents list.
2. Apply Convention A (upsert) with target title Design and the synthesized content.
3. Announce: "Design Document saved."

This synthesis step is the only place the Design artifact is produced — brainstorm and grill produce no persistent output.

Phase 3 — Spec Self-Review

After saving the Document:

1. Call get_document(id=<Design doc id>) to read back exactly what was saved.
2. Scan for: TBD · TODO · placeholder text · internal contradictions · ambiguous requirements.
3. Fix any issues found via save_document(id=<Design doc id>, content=<corrected>).

Success condition: a Design Document exists on WIL-X with approved, reviewed content. Nothing has been written to docs/superpowers/specs/ or to the issue description.

Phase 4 — User Review Gate

Tell the user:

"Design Document saved on WIL-X. Review it in Linear and let me know if you want changes."

Wait for their response:

• If they request changes: get_document(Design id), edit the content, save_document(id=...), re-run Phase 3 self-review, ask for approval again.
• If they approve: proceed to Phase 5.

Phase 5 — Label Conversion

1. Check the issue's current label (from the last get_issue call).
2. If label is Idea:
   • Ask: "What label should this become now — Feature, Improvement, or Bug?"
   • Call save_issue(id=WIL-X, labels=[chosen_label]).
3. If label is already Feature, Improvement, or Bug: leave it unchanged.

Confirm to the user: "Label updated to [label]."

Phase 6 — Status Transition to Refined

Apply Convention B with state="Refined":

1. Call save_issue(id=WIL-X, state="Refined").
2. Read the returned JSON; confirm "status":"Refined" before announcing.
3. If the call fails or returns a different status, report the error and do NOT announce Refined.

Close out with exactly:

✅ Design finalized in WIL-X (status: Refined). When you're ready to create the plan, ask.

Share the issue URL.

General Notes

• Write issue content in English, even if the user speaks Portuguese.
• Keep markdown clean — no raw HTML, no escape sequences.
• If the user interrupts mid-brainstorm or mid-grill, pause, answer, and resume only on their confirmation. Note the interruption in context but do not write it to the Document.
• If the design exceeds what fits comfortably in a single issue, flag it to the user rather than splitting silently — they may want to decompose into sub-projects (separate issues).
