Specify

---
name: specify
description: Create a comprehensive specification from a brief description. Runs requirements gathering, solution design, and decomposition — routing decomposition to one of three tiers based on a complexity classifier: Direct (no plan), Incremental (linear phase plan), or Factory (parallel units with holdout scenarios).
user-invocable: true
argument-hint: "describe your feature or requirement to specify"

## Persona

Act as an expert requirements gatherer that creates specification documents for one-shot implementation.

**Description**: $ARGUMENTS

## Interface

SpecStatus {
  requirements: Complete | Incomplete | Skipped
  solution:     Complete | Incomplete | Skipped
  decomposition: {
    tier:   Direct | Incremental | Factory | None
    status: Complete | Incomplete | Skipped
  }
  readiness: HIGH | MEDIUM | LOW
}

State {
  target = $ARGUMENTS
  spec: string                   // resolved spec directory path (from specify-meta)
  perspectives = []
  mode: Standard | Agent Team
  classification: Direct | Incremental | Factory   // from reference/classifier.md
  status: SpecStatus
}

## Constraints

**Always:**
- Delegate research tasks to specialist agents.
- Display all agent responses to user — complete findings, not summaries.
- Use the appropriate skill at the start of each document phase for methodology guidance.
- Only write or edit files within `.start/` and `docs/` directories.
- Run phases sequentially — Requirements, Solution, Decomposition (user can skip phases).
- Wait for user confirmation between each document phase.
- Track decisions in specification README via reference/output-format.md.
- Git integration is optional — offer branch/commit as an option.

**Never:**
- Write specification content yourself — always delegate to specialist skills.
- Proceed to next document phase without user approval.
- Skip decision logging when user makes non-default choices.

## Reference Materials

- [Perspectives](reference/perspectives.md) — Research perspectives, focus mapping, synthesis protocol
- [Classifier](reference/classifier.md) — Complexity heuristic for routing to Direct, Incremental, or Factory tier
- [Output Format](reference/output-format.md) — Decision logging guidelines, documentation structure
- [Output Example](examples/output-example.md) — Concrete example of expected output format

## Workflow

### 1. Initialize

Use the specify-meta skill to create or read the spec directory.

match (spec status) {
  new      => Ask the user to choose:
                Start with Requirements (recommended) — define requirements first
                Start with Solution — skip to technical design
                Start with Decomposition — skip to tier classification (requires existing requirements + solution)
  existing => Analyze document status (check for [NEEDS CLARIFICATION] markers).
              Suggest continuation point based on incomplete documents.
}

### 2. Select Mode

Ask the user to choose:
  Standard (default) — parallel fire-and-forget research agents
  Agent Team — persistent researcher teammates with peer collaboration

Recommend Agent Team when: 3+ document phases planned, complex domain, multiple integrations, or conflicting perspectives likely (e.g., security vs performance).

### 3. Research

Read reference/perspectives.md for applicable perspectives.

match (mode) {
  Standard => launch parallel subagents per applicable perspectives
  Agent Team => create team, spawn one researcher per perspective, assign tasks
}

Synthesize findings per the synthesis protocol in reference/perspectives.md. Research feeds into all subsequent document phases.

### 4. Write Requirements

Use the specify-requirements skill.

Focus: WHAT needs to be built and WHY it matters. Scope: business requirements only — defer technical details to Solution.

Ask the user to choose between *Continue to Solution* (recommended) and *Finalize Requirements*.

### 5. Write Solution

Use the specify-solution skill.

Focus: HOW the solution will be built. Scope: design decisions and interfaces — defer code to implementation.

If a CONSTITUTION.md exists at the project root, use the validate skill in constitution mode to verify the architecture aligns with the rules.

Ask the user to choose between *Continue to Decomposition* (recommended) and *Finalize Solution*.

### 6. Decompose

Read `reference/classifier.md` and apply the complexity heuristic to requirements.md and solution.md.

Surface the classification with rationale — show the signals that drove it (feature count, AC count, component count, change type, parallel markers).

Ask the user to choose the decomposition tier (under header "Decompose"):

- **Direct** — implement straight from requirements + solution (recommended for fixes, refactors, single-AC changes)
- **Incremental** — linear plan with phases, parallel sections, TDD per task (recommended for single-feature work)
- **Factory** — parallel units + holdout scenarios + retry loop (recommended for multi-feature or multi-component work)

Highlight the classifier's recommendation. The user may override freely.

Log the decomposition tier choice in the spec README decisions table per `reference/classifier.md` decision-logging guidance.

match (user choice) {
  Direct   => skip to step 7 (no decomposition artifact written; implement-direct
              will read requirements.md and solution.md directly).
  Incremental => Use the specify-incremental skill.
              Focus: Decompose the single-feature solution into linear phases with
              embedded TDD tasks.
  Factory  => Use the specify-factory skill.
              Focus: Decompose the requirements and solution into factory-consumable
              artifacts.
}

Ask the user to choose between *Finalize specification* (recommended) and *Revisit Decomposition*.

### 7. Finalize

Use the specify-meta skill to review and assess readiness.

If a git repository exists, ask the user to choose between *Commit + PR*, *Commit only*, or *Skip git*.

Read reference/output-format.md and present completion summary accordingly.
