EvanFlow: Brainstorming

Vocabulary

See evanflow meta-skill. Key terms used here: deep modules, deletion test, mockup quick-mode, grill.

When to Use

• "Help me think through X"
• "I want to build Y"
• New feature scoping
• Design questions where intent is unclear
• Before any creative work that will produce code

SKIP this skill when: the user is asking a factual question, requesting a quick mockup, or doing exploratory reading. EvanFlow has no skill tax — answer directly.

Mockup Quick-Mode

If the user says "show me mockups", "give me visual options", "let's see designs", or anything similar and is NOT asking to implement — skip everything below. Produce mockups directly in whatever form the project uses:

• HTML files (often easiest — write self-contained pages and tell the user where to open them, e.g., open mockup-1.html or via a local HTTP server)
• Figma frames (if the project uses Figma)
• ASCII layouts (for terminal UIs)
• Whatever the project's CLAUDE.md documents as the design-iteration medium

No spec doc. No plan. No git operations. Just iterate visually until the user picks a direction.

The Flow

1. Quick context check. Skim relevant files, recent commits, and any referenced docs. Do NOT exhaustively explore — just enough to ground the conversation.
2. Scope check. If the request describes multiple independent subsystems, flag it and propose decomposition before going further. Don't refine details on something that needs to be split.
3. Ask clarifying questions one at a time. Multiple-choice when possible (use AskUserQuestion). Focus on purpose, constraints, success criteria.
4. Propose 2–3 approaches with trade-offs and your recommendation as option (a). Lead with "here's what I'd do and why."
5. Embedded Grill (see below) — stress-test the chosen approach before committing.
6. Present the design in sections sized to their complexity. Get explicit approval after each section.
7. Decide: spec doc, straight to plan, or just go.

Embedded Grill

Once an approach is chosen, ask 3–5 sharp questions targeting:

• Hidden constraints: "What breaks if a user does X?"
• Reversibility: "If we ship this and it's wrong, what's the rollback?"
• Boundaries: "What's explicitly NOT in scope?"
• Existing patterns: "Is there code in the project that already does something similar? Should this conform or diverge?"
• Domain language: "Are we using the right terms from CONTEXT.md?"

For each question, propose a recommended answer. The user accepts, refines, or rejects. Don't grill on every single design — only when the choice has irreversibility, security, or domain-modeling implications.

Hard Rules

• Never auto-commit. Confirm in the current turn before any git op.
• No forced spec path. If a spec doc is appropriate, ask the user where to put it. Default suggestion: docs/specs/YYYY-MM-DD-<topic>.md. Don't write to any vendor-specific path unless user requests.
• No forced visual companion offer. Skip the browser-companion offer entirely; mockup quick-mode handles visual work directly.
• No skill tax. If the user is just chatting or asking a factual question, exit this skill — don't force the flow.

Hand-offs

• Spec written → evanflow-writing-plans (if non-trivial)
• Substantial new feature (sprint-sized, multi-stakeholder) → evanflow-prd instead of writing-plans
• Plan exists → evanflow-executing-plans (which itself offers evanflow-coder-overseer if the plan has 3+ parallelizable units)
• Just go → start with evanflow-tdd for the first behavior
• Domain term emerged → evanflow-glossary to update CONTEXT.md
• Interface shape is the hard part of the design → evanflow-design-interface before writing-plans
