Start a brainstorming session to create a feature specification (Codex, no sub-agents)	<feature-name>

Feature Specification or Bug Investigation

Start a collaborative session for: $ARGUMENTS

Mode Detection

First, determine if this is a Feature Request or a Bug Report:

Bug indicators: Words like "bug", "error", "broken", "not working", "wrong", "incorrect", "fails", "crash", "issue", problem descriptions, error messages, unexpected behavior descriptions.

Feature indicators: Words like "add", "create", "implement", "new", "feature", capability descriptions.

---

MODE A: Bug Investigation

If this is a bug report, follow this flow:

Bug Investigation Instructions

1. Do Deep Investigation

Before writing anything, thoroughly investigate the bug:

• Search the codebase for relevant code using rg
• Read the relevant files to understand the current implementation
• Trace the data flow to understand how the bug might occur
• Check tests to see what behavior is expected
• Look for similar patterns elsewhere in the codebase
• Check recent git commits that might have introduced the issue

2. Create Bug Brainstorming File

Directory naming with auto-increment:

1. Check existing directories in specs/YYYY-MM-DD/ (today's date)
2. Find the highest numeric prefix (e.g., if 0-roadmap, 1-core-domain, 2-ui-foundation exist, next is 3)
3. Create directory as: specs/YYYY-MM-DD/{{next_number}}-{{bug_name}}/brainstorming.md

Example: If specs/2026-01-06/ contains 0-roadmap/ and 1-auth-fix/, the next bug would be 2-{{bug_name}}/

Create the file at: specs/YYYY-MM-DD/{{N}}-{{bug_name}}/brainstorming.md

Use this structure:

# {{Bug Name}} - Investigation

**Date:** YYYY-MM-DD
**Status:** Investigating
**Reported Issue:** [Original bug description]

2. Step 2
3. Observe: [bug behavior]

---

## 6. Related Code & Tests

**Similar implementations:** [Reference similar patterns in codebase]

3. Present Findings and Ask for Direction

After creating the brainstorming file, summarize your findings and wait for user input on:

• Which fix option to pursue
• Answers to clarifying questions
• Any additional context

4. If Proceeding to Fix

Once direction is confirmed, you can either:

• Create a -specification.md for complex fixes (follow Feature mode Section 10+)
• Proceed directly to implementation for simple fixes

---

MODE B: Feature Specification

If this is a feature request, follow the original feature brainstorming flow:

Core Principle: Complete Specifications

Every requirement must be explicit and verifiable. Use checkboxes for ALL requirements so completion can be objectively measured. Ambiguity leads to incomplete implementations.

Feature Instructions

1. Create Q&A File

Directory naming with auto-increment:

1. Check existing directories in specs/YYYY-MM-DD/ (today's date)
2. Find the highest numeric prefix (e.g., if 0-roadmap, 1-core-domain, 2-ui-foundation exist, next is 3)
3. Create directory as: specs/YYYY-MM-DD/{{next_number}}-{{feature_name}}/brainstorming.md

Example: If specs/2026-01-06/ contains 0-roadmap/ and 1-auth/, the next feature would be 2-{{feature_name}}/

Create the brainstorming file at: specs/YYYY-MM-DD/{{N}}-{{feature_name}}/brainstorming.md (use today's date and the feature name from arguments, use hyphens for spaces in the folder name).

2. Initialize the Conversation

Start the Q&A file with this header:

# {{Feature Name}} - Q&A Session

**Date:** YYYY-MM-DD
**Status:** Brainstorming

---

2b. Explore Codebase First

Before asking the first question, explore the codebase to find:

1. Similar features - Search for existing implementations that solve related problems
2. Patterns in use - Identify Actions, Flows, Services, Livewire components in the relevant domain
3. Database schema - Check existing tables and relationships that might be relevant
4. Test patterns - Look at how similar features are tested

Use this exploration to:

• Make informed recommendations during Q&A
• Reference existing patterns ("Similar to how X works...")
• Identify potential reuse opportunities
• Spot integration points early

Tools to use:

• rg for search
• mcp__laravel-boost__database-schema for existing tables
• rg --files for finding files in relevant directories

3. Begin with Vision Question

Write the first message asking about the general vision:

---

## Message 1: Understanding Your Vision

### The Feature

**My Current Understanding:**
[Brief summary of what you think this feature might be about based on the name]

**Questions:**
1. What problem does this feature solve?
2. Who will use this feature?
3. What does success look like?

**Fabian's Comment:**

---

4. Conversation Flow

For each subsequent message, follow this structure:

---

## Message N: [Topic]

### [Sub-topic 1]

**My Current Understanding:**
[What you understand so far about this aspect]

**Questions:** (if needed)
- Question 1?
- Question 2?

**Recommendation:** (if applicable)
[Your recommendation with brief reasoning]

**Fabian's Comment:**

---

### [Sub-topic 2]
...

IMPORTANT: After user responds to your message, you MUST:

1. Update brainstorming.md with their response
2. Regenerate specification.md (see Section 4b)
3. Then write your next message

4b. MANDATORY: Regenerate Specification After Each User Response

CRITICAL: After processing each user response, regenerate the specification file. DO NOT skip this step.

The specification represents the current "mental model" of the feature. It evolves from rough vision to detailed specs.

After each Q&A round:

1. Read the full brainstorming.md to gather all accumulated decisions
2. Regenerate specification.md completely with:
   • All confirmed decisions as concrete requirements
   • Undecided items marked with [TBD] or [PENDING: <specific question>]
   • Assumptions marked with [ASSUMPTION: <text>]
3. Update status in frontmatter based on completeness
4. Update completeness score - count defined vs total requirements

Status Progression (with Definition of Done):

Status	Done When
Draft - Initial Vision	Section 1 (Overview) complete: problem, value, users defined
Draft - Requirements Gathering	Section 2 complete: all FR-/NFR- concrete and verifiable
Draft - Architecture Design	Sections 3-4 complete: components, data flow, schema specified
Draft - Detailing	Sections 5-9 complete: phases, UI/UX, tests have file paths
Ready for Implementation	Zero markers remain, Open Questions table empty, 100% completeness

Marker Usage:

• [TBD] - General "to be determined"
• [PENDING: How should X handle Y?] - Specific question blocking this item
• [ASSUMPTION: Users will always have Z] - Assumption made, needs validation

5. Use Diagrams

When helpful, include ASCII diagrams or Mermaid diagrams to visualize:

• Data flow
• Component relationships
• User journeys
• Database schemas

Example:

**Architecture Concept:**
```mermaid
graph LR
    A[User] --> B[Livewire Component]
    B --> C[Action]
    C --> D[Service]

### 6. Decision Tracking

Once a decision is made on a topic, update the Q&A file by adding a "Decisions Summary" section after the header (if not present):

```markdown
## Decisions Summary

| Topic | Decision |
|-------|----------|
| **Topic Name** | Brief decision statement |

7. Follow-up Questions

When you need input on specific choices, format questions like this:

---

### Q1: [Topic Name]

[Brief context for the question]

- [ ] **A) Option 1** - Description
- [ ] **B) Option 2** - Description
- [ ] **C) Option 3** - Description

**Recommendation:** [Your recommendation]

**Fabian's Comment:**

8. Session Rules

• Always append to the file - Never delete previous conversation
• Mark user comments inline - When Fabian adds comments, they stay in the "Fabian's Comment:" sections
• Update status as the spec progresses (see Section 4b for status definitions)
• Read the full Q&A file before each response to maintain context
• Ask one thing at a time - Don't overwhelm with too many questions
• Spec reflects mental model - brainstorming.md is the conversation log; specification.md is the current state

CHECKLIST - Execute after EVERY user response:

[ ] 1. Read user's comments in brainstorming.md
[ ] 2. Update Decisions Summary table with new decisions
[ ] 3. REGENERATE specification.md with current state (Section 4b)
[ ] 4. Write next message to brainstorming.md

9. Wrapping Up Q&A

When no [TBD] or [PENDING] markers remain in the specification and completeness is 100%, update the status to Ready for Implementation.

10. Specification Template Reference

This template is used by Section 4b for iterative updates. The specification is regenerated after each Q&A round, evolving from rough vision to detailed implementation plan.

Create the specification at: specs/YYYY-MM-DD/{{N}}-{{feature_name}}/specification.md (same directory as brainstorming.md)

The specification MUST contain the following sections with COMPLETE details.

CRITICAL FORMAT RULES:

1. ALL requirements MUST use checkboxes - Every single item that needs implementation gets a - [ ] checkbox
2. Requirements must be atomic - One checkbox = one verifiable action
3. No ambiguous language - Replace "should", "might", "could" with "must" or remove
4. Include file paths - Every implementation item should specify the file to create/modify
5. Group into phases - Each phase becomes one iteration during development
6. Acceptance criteria required - Each FR must have Given/When/Then criteria for testing

# {{Feature Name}} - Technical Specification

**Date:** YYYY-MM-DD
**Status:** Draft - Initial Vision
**Q&A Reference:** specs/YYYY-MM-DD/{{N}}-{{feature_name}}/brainstorming.md
**Completeness:** 0/0 requirements defined (0%)

12. Open Questions / Future Considerations

[Any items identified but deferred for later]

### 11. Critical Specification Review (Self-Validation)

After generating the specification, validate it yourself against the checklist:

- No logical inconsistencies between Q&A and specification
- All details discussed in Q&A are covered in the specification
- Implementation is technically feasible
- No scope creep beyond Q&A
- All requirements use checkbox format
- Requirements are atomic
- Each requirement specifies a file path
- Phases are clearly separated
- No `[TBD]`, `[PENDING]`, or `[ASSUMPTION]` markers remain
- Open Questions table is empty
- Completeness is 100%

If gaps remain, fix the specification and re-validate.

### 12. Final User Review

After validation passes:

1. Present the specification to the user for review
2. Make any corrections requested
3. Update status to `Approved` when confirmed
4. Inform the user:

> "The technical specification is complete. To implement:
> - Use `/dev specs/YYYY-MM-DD/{{N}}-{{feature_name}}/specification.md` for each phase
> - After each phase, invoke `/dev {spec} continue` to proceed
> - When all phases complete, use `/verify-complete {spec}` for final validation"

**STOP HERE - DO NOT PROCEED TO IMPLEMENTATION**

The `/spec` command ends after presenting the specification. Do NOT:
- Start implementing the feature
- Run `/dev` automatically
- Create any implementation files
- Write any code

Wait for the user to explicitly invoke `/dev` to begin implementation.

Now create the Q&A file and begin the brainstorming session by asking about the vision for: **$ARGUMENTS**
