Skip satisfied steps. If argument provided, skip to Step 2.
Interactive prompts: present options as a numbered list and wait for the user's choice.
Input
The argument is: $ARGUMENTS
If empty, go to Step 1; derive slug after gathering the idea. If provided, derive slug:
- Take only the text before the first
—or–(if present) - Strip leading command verbs: create, build, implement, add, update, fix, make, write, plan, get, show, support
- Lowercase the text
- Remove filler words: a, an, the, for, of, to, in, on, with, and, or, but, is, be
- Take the first 4 remaining words (or fewer if less exist)
- Join with hyphens →
<slug>
Output: .specs/specs/<slug>.md. If file exists, present options and wait:
- Overwrite existing (Recommended)
- Pick a new name
Workflow
1. Gather problem description
Ask the user for a detailed description of the problem and any solution ideas.
2. Explore codebase
Map current state: data models, services, API routes, frontend, tests. Note exists vs. must build.
Research protocol: codebase first, then docs. Unverifiable claims → flag as uncertain, never fabricate.
3. Interview
One question at a time. Lead with your recommended answer (mark it (Recommended) and list first). Explore code instead of asking when possible. Present 2–4 options for each question — structured choices are faster than free-text.
| Branch | Key questions | Skip when |
|---|---|---|
| Scope & Surface | Where? New page or integrated? Roles? | CLI/library, no new entry points |
| Data & Concepts | Definitions, existing vs missing data | Never skip |
| Behavior | Interaction patterns, filtering, search | No user-facing behavior |
| Display | Numbers, tables, charts, exports | No UI |
| Access & Privacy | Who sees what? Sensitive data? | Single-user, no auth |
| Boundaries | Out of scope, deferred features | Never skip |
| Integration | Schema, services, external deps | Self-contained change |
3b. Gray areas
Surface ambiguities, contradictions, unstated assumptions. For each gray area, present proposed resolution options. Resolve all before continuing.
4. Design modules
Sketch modules. Favor deep modules — simple interface (1-3 entry points) hiding large implementation over shallow modules where interface ≈ implementation.
Shallow signals: many small 1:1 functions, callers compose multiple calls, feature changes require interface changes.
Present modules. Confirm which need tests.
5. Write spec
Save to .specs/specs/<slug>.md (create dir if missing).
# Feature Name
Spec body structure. Omit empty sections. No file paths or code snippets.
## Problem Statement
## Current State (skip if greenfield)
## Solution (user experience, not architecture)
## User Stories (numbered, cover happy + edge + error)
## Implementation Decisions
### New Modules (name, purpose, interface signatures)
### Architectural Decisions (definitions, data flow, state)
### Schema Changes
### API Contracts
### Navigation
## Testing Decisions (behavior tests, key cases, prior art)
## Out of Scope (be specific)
Present options and wait for the user's choice:
- Run
/plan <slug>(Recommended) - Done for now
