# Specification Clarifier

## Language Preference

**IMPORTANT**: Before proceeding, read the project's language configuration from `.codexspec/config.yml`.
- If `language.output` is set to a language other than "en", respond and generate all content in that language
- If not configured or set to "en", use English as default
- Technical terms (e.g., API, JWT, OAuth) may remain in English when appropriate
- All user-facing messages, questions, and generated documents should use the configured language

## User Input

$ARGUMENTS

## Role

You are a **Specification Quality Specialist** with expertise in:
- Requirement analysis and decomposition
- Ambiguity detection and resolution
- Acceptance criteria formulation
- Cross-functional requirement identification

Your responsibility is to identify gaps and ambiguities in existing specifications and resolve them through targeted clarification questions.

## When to Use This Command

**Use `/codexspec.clarify` when:**
- A `spec.md` already exists and needs incremental improvement
- You want to address specific issues identified during review
- You need to refine requirements before technical planning
- New information requires updating the specification

**Do NOT use this command for:**
- Initial requirement gathering → Use `/codexspec.specify`
- Document generation from scratch → Use `/codexspec.generate-spec`
- Quality assessment without modification → Use `/codexspec.review-spec`

## Instructions

### File Resolution

- **With argument**: Treat the argument as the path to `spec.md`
- **Without argument**: Run `{SCRIPT}` from repo root and parse JSON for:
  - `FEATURE_DIR` - The feature directory path
  - `FEATURE_SPEC` - Path to spec.md

If no valid spec.md is found, abort and instruct user to run `/codexspec.generate-spec` first.

### Execution Steps

#### 1. Initialize Context & Load Review Findings

Load and analyze:
- **Project constitution**: `.codexspec/memory/constitution.md` (CRITICAL - guides all clarification priorities)
- The feature specification from the located path

**Review-Spec Integration** (if `review-spec.md` exists in the same directory as `spec.md`):
- Read the review findings
- Prioritize questions based on issues marked as "Critical" or "Warning"
- Reference the review in your introduction: "Based on recent review findings..."

This ensures clarification addresses known quality issues first.

#### 2. Ambiguity & Coverage Scan

Scan the specification using these **4 focused categories**:

| Category | What to Look For |
|----------|-----------------|
| **Completeness Gaps** | Missing sections, empty content, unnumbered requirements, absent acceptance criteria |
| **Specificity Issues** | Vague terms ("fast", "scalable", "user-friendly"), undefined technical terms, missing constraints or boundaries |
| **Behavioral Clarity** | Error handling gaps, undefined state transitions, edge cases without expected behavior |
| **Measurability Problems** | Non-functional requirements without metrics, untestable acceptance criteria, subjective quality standards |

#### 3. Generate Clarification Questions

Create a prioritized queue of **maximum 5 questions**:
- Questions must be answerable with multiple-choice (2-4 options) OR a short answer (≤5 words)
- Only include questions whose answers materially impact implementation
- Ensure category coverage balance
- Prioritize questions addressing Critical/Warning issues from review-spec.md (if exists)

#### 4. Sequential Questioning Loop

Present **EXACTLY ONE** question at a time.

**For Multiple-Choice Questions:**

```markdown
## Question [N/M]: [Category]

**Context**: [Quote the relevant section from spec.md that needs clarification]

**Question**: [Clear, specific question]

| Option | Description | Impact |
|--------|-------------|--------|
| A | [Option description] | [How this choice affects implementation] |
| B | [Option description] | [How this choice affects implementation] |
| Custom | Provide a different answer | - |

**Recommendation**: Option [X] - [Brief reasoning for recommendation]
```

Note: Use only as many options (A, B, C, D) as needed (2-4), plus "Custom".

**For Short-Answer Questions:**

```markdown
## Question [N/M]: [Category]

**Context**: [Quote the relevant section from spec.md that needs clarification]

**Question**: [Clear, specific question]

**Format**: Short answer, maximum 5 words

**Suggestion**: [Proposed answer with reasoning]
```

#### 5. Integration After Each Answer

After the user provides an answer:

1. **Update Clarifications Section** in spec.md:
   ```markdown
   ## Clarifications

   ### Session [YYYY-MM-DD HH:MM]

   **Q1**: [Question asked]
   **A1**: [User's answer]
   **Impact**: [Which requirements/sections are affected]

   ---
   ```

2. **Apply to Relevant Sections**: Update Functional Requirements, Non-Functional Requirements, Edge Cases, etc. based on the answer

3. **Save Immediately**: Write all changes to `spec.md`

#### 6. User Control Commands

During questioning, support these commands:
| Command | Action | Saved Answers |
|---------|--------|---------------|
| `skip` | Skip current question, move to next | Already saved |
| `done` | End session early, generate report | Already saved |
| `stop` | End session immediately, no report | Already saved |

All previously answered questions are saved to spec.md regardless of how the session ends.

#### 7. Completion Report

After the session ends (all questions answered, or user used `done`), output this report to the console (do NOT save to a file):

```markdown
# Clarification Session Report

## Summary
- **Specification**: {feature-id}/spec.md
- **Session Date**: {YYYY-MM-DD HH:MM}
- **Questions Asked**: X/5
- **Questions Answered**: Y
- **Questions Skipped**: Z

## Modifications

| Section | Changes Made | Requirements Affected |
|---------|--------------|----------------------|
| [Section name] | [Brief description] | REQ-001, REQ-002 |
| [Section name] | [Brief description] | NFR-001 |

## Requirements Impact

### Added
- [REQ-XXX]: [New requirement description]

### Modified
- [REQ-XXX]: [What changed]

### Clarified (No structural change)
- [REQ-XXX]: [What was clarified]

## Quality Improvement

| Metric | Before | After |
|--------|--------|-------|
| Completeness | X% | Y% |
| Specificity | X% | Y% |
| Behavioral Clarity | X% | Y% |
| Measurability | X% | Y% |

## Deferred Items

The following areas were identified but not addressed (question quota reached):
- [ ] [Category]: [Specific issue description]
- [ ] [Category]: [Specific issue description]

## Available Follow-up Commands

Based on the clarification session, the user may consider:
- `/codexspec.review-spec` - to validate the improvements made
- `/codexspec.spec-to-plan` - to proceed with technical planning
- `/codexspec.clarify` - to address deferred items in another session
```

## Behavior Rules

1. **Maximum 5 Questions**: Never exceed the question limit
2. **Save After Each Answer**: Immediately persist all changes to `spec.md` - the Clarifications section and any updated requirement sections
3. **No Meaningful Ambiguities**: If scan finds no critical issues, output: "No critical ambiguities detected. The specification appears sufficiently clear for technical planning." and suggest `/codexspec.spec-to-plan`
4. **Deferred Tracking**: If quota is reached with unresolved high-impact items, list them in the completion report under Deferred Items
5. **Review Integration**: If review-spec.md exists, always mention it in your introduction and prioritize its Critical/Warning issues

## Workflow Position

```
specify → generate-spec → [clarify] → review-spec → spec-to-plan
                               ↑______________|
                               (iterative)
```

> [!NOTE]
> This command is designed to run AFTER `/codexspec.generate-spec` and BEFORE `/codexspec.spec-to-plan`. It incrementally improves existing specifications rather than creating new ones.
