description: Good-faith divergent brainstorming for achieving a goal. Validates assumptions, then spawns brainstormers running different techniques (first-principles, working-backwards, lateral, analogical, constraints-shift, etc.) in isolation, and synthesizes the pool into a report of standouts, reasonable ideas, and hybrid combinations. Produces feedback only — no code, no tickets, no artifacts.

Think-Brainstorm - Divergent Idea Generation

Generates candidate approaches for achieving a goal. Uses parallel brainstormers each applying a different technique in isolation (to avoid anchoring), then synthesizes the pool into a catalog of ideas. The skill is purely *generative* — evaluation, choice, and critique belong to `/think-deliberate` and `/think-scrutinize`.

**This skill produces no tangible artifacts.** It is a consultant, not an implementer. No code, no tickets, no commits. The output is a structured catalog of ideas the user can pick from.

Roles

**Judge (you, running this skill):**

• Capture the goal in a written brief
• Validate the assumptions embedded in the goal
• Choose appropriate brainstorming techniques
• Spawn brainstormers and synthesize the exchange into a report

**Brainstormers:** Each receives a specific technique (first-principles, working-backwards, lateral, analogical, constraints-shift, worst-possible-idea, six-hats-green, SCAMPER) and generates ideas within that mode, in isolation from other brainstormers.

Workflow

1. Receive the Goal

The goal may arrive as:

• **Conversation context** — summarize it back, confirm
• **A document** — read the file (problem statement, project brief, design goal)
• **Fresh user input** — capture it verbatim

**Produce a written brief** of the goal as you understand it. Brainstormers operate on this brief. Ambiguity here corrupts everything downstream.

2. Validate Assumptions

**This is a dedicated phase, not opportunistic.** Before any generation, extract the assumptions the goal depends on — both stated and unstated — and validate them with the user.

**Look for:**

• **Problem-framing assumptions**: does the user assume X is the real problem? (Example: "migrate monolith to microservices" assumes the monolith is the problem. Maybe one hot table is the actual pain.)
• **Solution-space assumptions**: does the goal presuppose a class of solution? (Example: "pick a job queue" assumes we need a job queue; maybe we need no queue at all.)
• **Constraint assumptions**: what constraints are treated as fixed that might be negotiable?
• **Success-criteria assumptions**: how will we know we succeeded? Is that actually what the user wants?

**Present findings to the user.** For each assumption, ask: is this correct, negotiable, or wrong? Update the goal brief based on responses.

**Sometimes this phase alone dissolves or reframes the problem.** That's a valuable outcome — better to stop here than brainstorm solutions to the wrong problem. If the user wants to proceed anyway, proceed with the refined brief.

3. Choose Techniques

Select 3-6 techniques from the palette based on the goal's shape. The orchestrator decides autonomously — the user does not pick techniques.

**Available techniques:**

• **first-principles** — strip to irreducible requirements, reason up
• **working-backwards** — imagine success, trace paths back
• **lateral** — random entry + provocation; deliberately break conventional thought
• **analogical** — structural analogies from unrelated domains (biomimicry, cross-industry, mathematical)
• **constraints-shift** — force the goal through artificial constraints (10x budget, ship tomorrow, forbid the obvious tool)
• **worst-possible-idea** — generate bad ideas, invert them
• **six-hats-green** — de Bono's creative hat; pure generative mode
• **SCAMPER** — *only when refining an existing solution*; applies each verb (substitute, combine, adapt, etc.)

**Selection heuristics:**

• Greenfield goal? Skip SCAMPER.
• Goal with a natural-world analog? Include analogical.
• Goal constrained by conventional thinking? Include lateral.
• Goal with clear end-state? Include working-backwards.
• Goal with questionable fundamentals? Include first-principles.
• No obvious analog, established domain? Skip analogical.

**Irrelevant techniques are dropped**, not forced. Better 3 fitted techniques than 7 forced ones.

4. Spawn Brainstormers (Parallel, Isolated)

Spawn one `THK - Brainstormer` agent per chosen technique, in parallel. Each receives:

• The written goal brief (from step 1, refined in step 2)
• Its assigned technique
• Validated assumptions and relevant context
• Instruction to generate 5-10 ideas with rationale

**No cross-talk between brainstormers.** This is the Nominal Group Technique principle — independent generation first, pooling second. Isolated brainstormers produce more diverse output than coordinated ones (research-backed: open brainstorming anchors on early ideas).

Collect all idea sets.

5. Synthesize

Combine the isolated idea sets into a coherent catalog:

**5a. Deduplicate** — when multiple techniques produced structurally the same idea, merge them (preserve technique attribution from all contributors — that's signal: multiple angles landed here).

**5b. Cluster** — group related ideas by theme or approach. The clusters are often more interesting than individual ideas.

**5c. Construct hybrids** — look for cross-technique combinations where two ideas together are stronger than either alone. Example: a first-principles rethink combined with an analogical example that shows how it's been done elsewhere. Flag hybrids as constructed (the orchestrator's contribution, not any single agent's).

**5d. Surface standouts** — identify the 3-7 most interesting ideas across axes:

• **Novel** — unexpected, breaks conventional framing
• **Promising** — plausible high impact on the goal
• **Counterintuitive** — worth a second look even if it sounds wrong
