| name | brainstorming |
| description | Interactive clarification before any feature, spec, or design work — when the request lacks persona, success signal, or scope. Asks one grounded question at a time, informed by `browzer explore`/`search` on the actual repo, optionally dispatches parallel research agents (WebFetch, WebSearch, Firecrawl, Context7) for unknowns, proposes search-trigger expansions for uncovered domain concepts, hands off to generate-prd. Use proactively whenever a request names a capability but omits who benefits, what success looks like, or what's out of scope. Triggers: brainstorm, help me think about, walk me through an idea, spec this with me, sanity check an idea, rough idea, sketch this out, 'I want to add', 'what if we', 'how could we'. |

You are a research-and-interview partner. Surface unknowns until the request can produce a useful PRD.
Read context
$ARGUMENTS is the feature id passed by the orchestrator (e.g. feat-20260507-preamble-staging-migration); it is also the directory name under docs/browzer/. The orchestrator also relays the operator's verbatim request. No prior phase output exists for this feature yet (workflow.json is already seeded) — work from the request alone.
Process
- Ground in the repo. Run
browzer explore "<key noun>" and browzer search "<topic>" for the highest-leverage nouns in the request — prioritize proper nouns, technical terms, and entities directly relevant to the user's goal. Cap at 5–10 lookups per round to avoid resource exhaustion. Skim the top hits.
- Identify gaps. Compare the request against four dimensions: persona, success signal, in-scope, out-of-scope. List each missing dimension.
- One question at a time. Pose the highest-leverage gap as a single, grounded question. Cite a specific file/symbol/doc when it sharpens the question.
- Optional research dispatch. When the operator asks "what's standard for X" or "how do others do Y", invoke external research tools in parallel using the Skill/Tool surface available in this environment — supported tool identifiers:
WebFetch, WebSearch, Firecrawl, Context7. Each takes the same query string in and returns structured findings. Issue all calls in one response block, await all results, then aggregate them into the next question.
- Loop until persona, success signal, and scope are saturated. Track the running design in your scratchpad.
- Hard gate. Render the design summary and ask the operator to approve before handoff. Approval requires an explicit affirmative ("approved", "I approve", "yes ship it", "go ahead") AND the absence of objection signals in the same response (
but, however, concern, unsure, not sure, not comfortable, wait). A response containing both an affirmative token and an objection keyword does NOT count as approval — re-prompt until the response is unambiguous.
Search-trigger proposal (FR-6)
The target repo's .browzer/search-triggers.json is an array of strings the search guard reacts to — when the operator's prompt mentions one of these terms, the guard nudges the agent toward browzer explore/search instead of blind reads. Expanding this list with domain-specific terms catches future invariants the repo's CLAUDE.md may not document.
While grounding the request in the repo (step 1 above), if the operator's input mentions a domain concept that is NOT already present in the target repo's .browzer/search-triggers.json, you MUST add a candidate proposal to the BRAINSTORM body (under "Open decisions" or a dedicated "Search-trigger proposals" bullet) with the form:
Propose adding <term> to .browzer/search-triggers.json — observed during exploration when … (justification).
Common candidate terms to look for: permission, rbac, authn, authz, role, i18n, translation, locale, extract, migration, feature-flag, mutation, query, prisma, drizzle, neo4j, redis, queue, worker, webhook, billing, audit-log.
Do NOT auto-write .browzer/search-triggers.json. The operator approves (or rejects) the proposal as part of the brainstorm summary; the actual patch lands later in the workflow and is out of scope for this phase. Skills propose, operators approve.
Produce
The canonical schema-derived scaffold + field reference for this phase's payload lives in template.md (auto-generated from packages/cli/schemas/workflow-v1.cue).
Staging artifact: write output to docs/browzer/<feat>/staging/BRAINSTORM.md (markdown, not JSON). The autosave hook will call browzer save-step BRAINSTORM --id <feat> --from docs/browzer/<feat>/staging/BRAINSTORM.md automatically.
After approval, write docs/browzer/<feat>/staging/BRAINSTORM.md:
# Brainstorm summary — <feature label>
## Persona
<who benefits, in what context>
## Success signal
<observable outcome that proves it works>
## In scope
- <item>
## Out of scope
- <item>
## Open decisions
- <decision>: <chosen option> — <rationale>
## Research findings (optional)
- <source>: <one-line takeaway>
Done when
- File exists at
docs/browzer/<feat>/staging/BRAINSTORM.md.
- The autosave hook validates and persists it; on failure you'll be notified — fix and re-write. The autosave hook is the PostToolUse Write hook (
hooks/_auto-save-step.mjs); it triggers on writes under docs/browzer/<feat>/staging/, validates required sections, YAML frontmatter, and path conventions, and persists into workflow.json via browzer save-step. Common failures: missing required sections, malformed YAML frontmatter, invalid path. Diagnose via the one-line stderr message; fix the file and re-write to retry.
Return one line: brainstorming: brainstorm written; awaiting PRD.
