Brainstorming Skill

Overview

Collaborative design exploration for new features, architecture decisions, and complex problem-solving. In the collapsed flow, there is no separate design phase — /exarchos:ideate authors the ## Design & Rationale section of one unified docs/specs/ artifact, then auto-chains to /exarchos:plan, which adds the ## Decomposition section to the same document. The single approval point is plan-review (a dispatched, fresh-context adversarial pass over the unified doc).

The artifact shape is owned by the unified spec template — author against it, do not restate it: see @skills/plan/references/spec-template.md.

Triggers

Activate this skill when:

• User says "let's brainstorm", "let's ideate", or "let's explore"
• User runs /exarchos:ideate command
• User wants to discuss design rationale before decomposition
• A problem has multiple valid solutions needing evaluation (the deep rung)

For a complete worked example, see references/worked-example.md.

Planning depth (one-pass by default; deep gates the divergent loop)
