Brainstorm - Design-First Ideation

Scheduling

Goal

Explore user intent, constraints, and alternative approaches before planning or implementation, then preserve an approved design for downstream planning.

Intent signature

• User says they have an idea, want to brainstorm, compare approaches, explore concepts, or design before planning.
• Request is ambiguous enough that implementation or task planning would be premature.

When to use

• Exploring a new feature idea before planning
• Understanding user intent and constraints before committing to an approach
• Comparing multiple design approaches with trade-offs
• When the user says "I have an idea" or "let's design something"
• Before invoking /plan for complex or ambiguous requests

When NOT to use

• Requirements are already clear and well-defined -> use oma-pm directly
• Implementing actual code -> delegate to specialized agents
• Performing code reviews -> use oma-qa
• Debugging existing issues -> use oma-debug

Expected inputs

• Early idea, ambiguous goal, product concept, design question, or set of constraints
• Existing project context when the idea must fit a codebase or product direction
• User preferences and approval gates

Expected outputs

• Clarified intent and constraints
• Two or three approaches as prose briefs (scenario, mechanism, residual risk) plus a comparison matrix and recommended option
• Section-by-section approved design document
• Blind-review issue list (Tier 1 resolved, Tier 2/3 resolved or explicitly deferred)
• Saved design artifact before handoff to planning

Dependencies

• Shared context loading, reasoning templates, clarification protocol, quality principles, and skill routing
• Optional resources/triz-lite.md for contradiction-shaped approach seeding
• Per-agent reviewer dispatch (e.g. qa-reviewer, architecture-reviewer) for the high-stakes blind-review escalation path
• Downstream PM workflow for task decomposition after design approval

Control-flow features

• Branches by ambiguity, user answers, approach comparison, and approval gates
• Optional TRIZ-lite branch when a technical/UX contradiction blocks distinct approaches
• Asks one question at a time
• Blind review round before save; may dispatch fresh-context reviewer subagents for high-stakes designs (the only subagent-spawning path in this skill)
• Stops before implementation or task planning

Structural Flow

Entry

1. Confirm that the request is exploratory rather than ready for implementation.
2. Load enough project context to understand constraints.
3. Start with intent and constraints, not solutions.

Scenes

1. PREPARE: Explore context and frame the design question.
2. ACQUIRE: Ask clarifying questions one at a time.
3. REASON: Generate two or three approaches with tradeoffs.
4. VERIFY: Get user approval section by section, then run a blind review round (independent lenses critique without seeing each other's feedback) before saving.
5. FINALIZE: Save design and transition to planning when appropriate.

Transitions

• If requirements become clear and implementation-ready, transition to PM planning.
• If user rejects an approach, revise before moving to detailed design.
• If implementation pressure appears early, defer it until design approval.
• If approaches collapse into knob-turning on one axis, load resources/triz-lite.md and reseed, then re-present prose briefs.

Failure and recovery

• If the user cannot answer a question, propose assumptions and ask for confirmation.
• If scope expands, split the design into smaller sections.
• If alternatives collapse into one option, identify the real constraint causing that; use TRIZ-lite only when that constraint is a technical/UX contradiction.

Exit

• Success: approved design exists and is ready for planning.
• Partial success: open questions and assumptions are explicit.

Logical Operations

Actions

Action	SSL primitive	Evidence
Read context and idea	READ	User prompt and project context
Ask targeted questions	REQUEST	Clarification phase
Compare approaches	COMPARE	Tradeoff matrix
Infer recommendation	INFER	Recommended option
Emit option-selection decision	CALL_TOOL	oma state:emit + oma state:verify --checkpoint option-selection
Validate approval	VALIDATE	Section-by-section confirmation
Run blind review	VALIDATE	Independent lens critiques, tiered issue list, Tier 1 resolution
Write design artifact	WRITE	docs/plans/designs/ and memory
Transition to plan	NOTIFY	Handoff summary

Tools and instruments

• Context loading, reasoning templates, clarification protocol
• Optional TRIZ-lite resource for contradiction seeding
• Project memory and docs/plans/designs/ for persisted designs

Canonical workflow path

1. Ask one clarifying question at a time.
2. (Optional) If technical/UX contradiction or same-axis approaches only → resources/triz-lite.md.
3. Present 2-3 approaches as prose briefs, then matrix, then recommendation; get user pick, then emit and verify the `brainstorm.option-selection` L1 decision.
4. Design section by section with user approval, then blind review: 4-8 independent lenses critique the design; resolve Tier 1 issues (fresh-context reviewer subagents for high-stakes designs).
5. Save the approved design to `docs/plans/designs/` before handing off to planning.

Resource scope

Scope	Resource target
MEMORY	User intent, assumptions, decisions
CODEBASE	Existing project context when relevant
LOCAL_FS	Approved design artifacts; optional TRIZ-lite appendix in design doc

Preconditions

• The user is still exploring or the request is ambiguous.
• The agent can ask clarifying questions before implementation.

Effects and side effects

• Produces design decisions and persisted design docs.
• Influences downstream planning but does not implement code.

Guardrails

1. No implementation or planning before design approval - brainstorm produces a design document, not code or task plans
2. One question at a time - ask clarifying questions sequentially, not in batches
3. Always propose 2-3 approaches - mechanistically distinct when possible; label each tactical or structural. The recommended option defaults to structural and must address the root cause. Recommend tactical only for genuinely throwaway scope, not merely because of deadline or effort pressure; include trade-off analysis.
4. Prose before matrix - explain each approach with scenario, plain-language mechanism, solves/leaves, and cost feel; then comparison matrix; then recommendation. Do not lead with matrix-only output
5. Section-by-section design - present design incrementally with user confirmation at each step
6. Blind review before save - mandatory unless the design is trivially small (1-2 files, low stakes); lenses critique independently; use fresh-context reviewer subagents for architecturally significant, hard-to-reverse, or security-/compliance-sensitive designs
7. YAGNI - do not over-engineer; design only what is needed for the stated goal
8. TRIZ-lite is optional - only for technical/UX contradictions or same-axis collapse; max 3–5 principles from the curated set; no fake scores, full TRIZ/ARIZ, or classical matrices; seeds feed Step 3 briefs and do not replace user approval
9. Save design, then transition - persist the approved design document before handing off to /plan

Execution Phases

Follow the brainstorm workflow step by step:

1. Phase 1 - Context: Explore the existing codebase and understand the project landscape
2. Phase 2 - Questions: Ask clarifying questions one at a time to understand intent and constraints
3. Phase 3 - Approaches: Optionally seed with TRIZ-lite when contradiction-shaped; present 2-3 prose approach briefs labelled tactical/structural, a matrix, and an engineering-first structural recommendation unless the work is genuinely throwaway
4. Phase 4 - Design: Present the detailed design section by section, getting user approval at each step
5. Phase 5 - Blind Review: Run 4-8 independent reviewer lenses on the design, consolidate into Tier 1/2/3 issues, resolve Tier 1 before save; escalate to fresh-context reviewer subagents for high-stakes designs. Skip only for trivially small designs (1-2 files, low stakes)
6. Phase 6 - Documentation: Save the approved design to docs/plans/designs/ and project memory
7. Phase 7 - Transition: Hand off to /plan for task decomposition

Common Pitfalls

• Jumping to solutions: Asking "how" before fully understanding "what" and "why"
• Too many questions at once: Overwhelming the user with a wall of questions
• Single approach bias: Presenting only one option without alternatives
• Matrix-only options: Dumping a trade-off table without scenario/mechanism prose so the user cannot choose
• Same-axis "alternatives": Three intensities of the same knob (interval/TTL/debounce) presented as distinct approaches
• TRIZ on everything: Loading triz-lite without a real contradiction, adding ceremony without better options
• Over-engineering: Designing for hypothetical future requirements instead of stated needs
• Skipping confirmation: Moving forward without explicit user approval on design decisions
• Skipping blind review: Saving a non-trivial design without the independent critique round, or letting the design's author-context leak into escalated reviewer prompts
