Brainstorming
Brainstorm before you build
- Before starting any creative or feature work — a new feature, added functionality, a behavioral
change, a nontrivial design decision — stop and run this workflow before writing implementation code.
- The aim: turn the request into a validated design, recorded as a spec-graph
task-spec, that the user
has explicitly approved — not a guess you implement and hope lands.
- Never implement during brainstorming. If you catch yourself opening a source file to make a change
before the design is approved, stop.
Anti-pattern: "this is too small to need this"
Every request goes through this, however small it looks. A one-line config change and a new subsystem
both benefit from a few minutes of "what does the user actually want and why" — that is where wrong
assumptions get caught cheaply. Scale the depth to the task; never skip the workflow entirely.
The workflow
- Orient. Use the spec-graph skill's tools first —
spec_grep/spec_get/spec_graph — to find
what the project already says about the area; read code second, to confirm details.
- Scope check. If the request bundles multiple independent features or subsystems, say so and
brainstorm them one at a time (or in parallel sub-sessions, the user's call) — don't blend unrelated
decisions into one task-spec.
- Open a task-spec. As soon as you understand roughly what's being asked,
spec_create a
task-spec (id, title, status: draft, parent: the nearest relevant module) to hold the design as it
develops. This file is the one artifact — update it live as decisions land; don't also keep a separate
scratch doc. This works even in a project with no existing spec graph: a task-spec only needs
frontmatter id and type to be a valid spec, no pre-existing graph required — don't skip this step
just because nothing else in the project is specced yet.
- Clarify. Ask what you need via
ask_user_question. Its own guidance applies: batch related
questions into one call (up to 4), put a recommended option first, and don't chain calls
back-to-back — resolve a full round, update the task-spec with what you learned, and only open a new
round if the answers raised a genuinely new question. If the host reports no UI (ask_user_question
returns "not available"), state your best-guess assumptions explicitly in the task-spec instead of
blocking.
- Propose approaches. Once the ask is clear, write 2-3 approaches into the task-spec with
trade-offs and a recommendation. When approaches are easiest to compare side by side, ask via a
single-select
ask_user_question with each approach as an option (label = approach name, description
= its trade-off) instead of prose alone.
- Present the design. Write it into the task-spec in sections scaled to their complexity; confirm
with the user as each section lands, not only at the end.
- Self-review. Before asking for final sign-off, reread the task-spec for: placeholders/TBDs,
sections that contradict each other, scope that's actually multiple task-specs, and ambiguous
requirements — fix what you find, don't just flag it.
- Promote. When the design settles a boundary, contract, or decision that belongs in a durable
spec, fold it into the relevant module's
SPEC.md now — spec_create for a new module, spec_update
for its frontmatter (draft → active as it firms up), edit for prose. Run spec_validate after
structural changes.
- Final review, then build. Ask the user to review the (now-promoted) design once more. Once
approved, implement directly against it — there is no separate plan-writing step here. Keep the
task-spec and the durable specs honest as the code lands, and retire the task-spec once the work
itself is done, not merely once the design was promoted.
Working with ask_user_question
- This tool batches: up to 4 multiple-choice questions per call, 2-4 options each, a free-text
fallback row on every question (additive alongside the checks on multi-select), an always-available
Skip. It is not a one-question-at-a-time
chat turn — group what you need into a round, and don't call it again immediately after with a trivial
follow-up.
- Always put your recommended option first and label it "(Recommended)" when you have one.
- Use
options[].preview (markdown) when a concrete comparison — code, a config, an ASCII mockup — is
clearer shown than described.
- A user who skips or leaves questions unanswered is not a blocker: record the resulting assumptions in
the task-spec, explicitly marked unconfirmed, and continue.
What a good task-spec looks like
- Scoped to one piece of work — if it's accreting unrelated decisions, split it.
- States the request, the decision(s) made and why, the approaches considered and why they were or
weren't picked, and anything the user explicitly deferred or declined to answer.
- Gets promoted, not copied: once a decision belongs in a module's
SPEC.md, move it there and
reference it from the task-spec rather than keeping two copies that can drift.
