create-exp-plan

name	create-exp-plan
description	Use when a feature needs to be planned/designed in the Exploration step, or when the user says "EXP plan", "feature plan", "exploration plan", "design the feature". Produces an EXP plan/spec per chevp-ai-framework templates.

Create Exploration-Plan (EXP)

Step 2 artifact: captures HOW the feature will be built, the chosen approach, risks, and acceptance criteria.

Prerequisite

G1 must be passed. Before creating, verify via the gate-validator subagent (gate=G1). If G1 is not passed, block and redirect to /context.

Steps

1. Read templates: templates/plan-template.md and templates/spec-template.md.
2. Read the Exploration step guide: 02-exploration/README.md and 02-exploration/ai-plans.md.
3. Check guidelines/plan-granularity.md (project-level override takes precedence) for size limits and plan type.
4. Assign the next EXP number by scanning existing plans.
5. Draft the plan with:
   • Problem statement and motivation (derived from CTX)
   • Chosen approach and considered alternatives
   • Scope (in / out)
   • Acceptance criteria (testable)
   • Risks and open questions
   • Required ADRs (new or referenced)
   • UX prototype requirement (Yes / No + reason)
6. Confirm path, number, and content with user before writing.

Output

An EXP plan file. Status is Draft until human approves (required for G2).
