\n\nDesign it in the browser, approve it at the gate, hand the blueprint to the\nblacksmith: blueprint → forge → blacksmith-orchestrate.
\n
Blueprint owns the whole UI/UX brainstorming arc: harvest the project's real\ndesign language, push interactive proposal screens, resolve rounds through\nclipboard-pasted responses, gate on approval, write the spec, and hand off to\nplans, tickets, or orchestration. The browser never talks back to the agent —\nthe user's paste is the only return channel, so the companion server keeps no\nstate and its death mid-session loses nothing.
\nThe interactive machinery ships in scripts/ and is never\nreimplemented inline; each session authors only HTML content fragments per\nreferences/screens.md.
\nFlags compose and are parsed from anywhere in the invocation; the canonical\nmatrix with composition rules is references/flags.md.
\n| Flag | \nEffect | \n
|---|---|
fresh | \nForce a full design re-harvest, ignoring the .brainstorm/ cache | \n
terminal | \nSkip the browser; run every round in the terminal fallback | \n
resume | \nContinue from an existing ledger: restart the server, re-push the last unresolved screen | \n
Use for UI/UX brainstorming: new screens, redesigns, component-level polish,\nanything where the user should see options before choosing. If the topic\nhas no visual dimension (pure backend or API design), say so in one line and\ndefer to a plain brainstorming workflow instead of forcing a browser on a\ntext problem.
\nPart 1 — Setup (1–3): classify → harvest → start companion\nPart 2 — Rounds (4–5): push screen → read pasted response, ledger it (loop)\nPart 3 — Close (6–8): [GATE] recap + approval → spec → handoff\nConfirm the topic is visual (see When to Use). Parse flags. Enumerate the UI\nitems in scope — sessions typically batch several; each becomes a track\nthrough the rounds.
\nBuild or refresh .brainstorm/style.css and .brainstorm/design-notes.md\nper references/harvest.md. No screen may be pushed\nbefore the harvest exists.
Run node <skill>/scripts/serve.mjs --project-dir <project> --open in the\nbackground. Verify aliveness by statting .brainstorm/server-info; share the\nprinted URL every round as fallback. If the server cannot start twice, or the\nterminal flag is set, degrade per the terminal-fallback section of\nreferences/screens.md with a one-line warning.
Author a content fragment per references/screens.md\ninto .brainstorm/screens/, then summarize in the terminal what is on\nscreen and ask the user to click and paste.
HARD GATE: nothing touches the target codebase before Step 6 approval. No\nflag bypasses this.
\nParse the pasted response per\nreferences/composer.md: verify the screen header,\nmap answers by order, treat nits as change requests. Append decisions to the\nledger per references/ledger.md. Revise (new -vN\nscreen) or advance; push a waiting screen when returning to terminal-only\ndiscussion.
Push a recap screen rendered from the ledger (data-mode=\"recap\"). The user\napproves in the terminal, or clicks Copy approval and pastes the phrase.\nNo approval → stop here.
Assemble the design doc from the ledger into\ndocs/specs/YYYY-MM-DD-<topic>-design.md: design decisions per UI item plus\na one-line-each \"Rejected alternatives\" appendix. Self-review for\nplaceholders, contradictions, scope, ambiguity; fix inline; commit.
Push the handoff screen per\nreferences/handoff.md: plans route, /to-tickets\nroute, and the blacksmith invocation builder with generated flag chips.
New lessons go to references/anti-patterns.md,\nthe canonical home — not into this file.
