Launchpad Spec

Iterative feature development framework ensuring zero ambiguity before execution.

Quick Reference

Command	Purpose	Input
/lp:spec <intent>	Create spec from "I want to build/add X"	Feature description
/lp:refine [section]	Improve spec with research	Optional section focus
/lp:clarify <response>	Answer clarification questions	Your response
/lp:tasks	Break spec into executable tasks	None (uses active spec)
/lp:run-task [task#]	Execute tasks with TDD	Optional task number

Core Principle

Iterate until clarity: No task execution begins until ALL questions are resolved and the spec is unambiguous. Claude must be able to execute without interruptions.

---

Phase 1: /lp:spec - Create Specification

Trigger: /lp:spec <description> or "I want to build/add X"

Workflow

1. Check specs/ folder:

   • If missing: Create specs/ and specs/README.md
   • If exists: Read specs/README.md for project overrides

2. Detect project context:

   • Scan repo for language indicators (go.mod, pyproject.toml, package.json, etc.)
   • Note primary language(s) for later skill invocation
   • Check specs/README.md for language overrides

3. Generate spec file:

   • Filename: specs/{feature-slug}.md (kebab-case)

4. Fill initial sections:

   • Parse user intent into Objective
   • List initial requirements (functional/non-functional)
   • Mark status as DRAFT

5. Generate clarifying questions:

   • Identify ambiguities, edge cases, unknowns
   • List as numbered questions in "Open Questions" section
   • STOP and present questions to user

Output

Created: specs/feature-name.md (DRAFT)

Questions requiring clarification:
1. [Question about scope]
2. [Question about behavior]
3. [Question about constraints]

Use `/lp:clarify` to answer, or `/lp:refine` to research solutions.

Phase 2: /lp:refine - Research & Improve

Trigger: /lp:refine [section] (e.g., /lp:refine solution, /lp:refine requirements)

Workflow

1. Load active spec: Find most recent DRAFT spec in specs/

2. Check project conventions:

   • Read specs/README.md for behavior overrides
   • Load relevant language skill (auto-detected or overridden)

3. Research phase:

   • Search codebase for similar patterns
   • Check skill references for best practices

4. Update spec:

   • Fill "Technical Strategy" with concrete approach
   • Add architecture decisions with rationale
   • Update requirements based on findings

5. Re-evaluate clarity:

   • Are there new questions?
   • Are existing questions resolved?
   • If questions remain: STOP and present them

---

Phase 3: /lp:clarify - Answer Questions

Trigger: /lp:clarify <response> or /lp:clarify Q1: answer, Q2: answer

Workflow

1. Load active spec with open questions

2. Parse user response:

   • Match answers to numbered questions
   • Accept free-form responses for single questions

3. Update spec:

   • Move answered questions to relevant sections
   • Add decisions/constraints to Requirements or Strategy
   • Remove resolved questions from "Open Questions"

4. Check for new questions:

   • Does the answer introduce new ambiguities?
   • If questions remain: present them
   • If no questions: announce spec is ready for /lp:tasks

Example

User: /lp:clarify Q1: We need OAuth2 with Google provider only. Q2: No, admin can also delete.

Updated specs/auth-system.md:
- Added OAuth2/Google to Technical Strategy
- Updated permissions: admin can delete

Remaining questions: None
Spec is ready. Use `/lp:tasks` to create task breakdown.

---

Phase 4: /lp:tasks - Task Breakdown

Trigger: /lp:tasks

Prerequisites

• Active spec must have status DRAFT or APPROVED
• "Open Questions" section must be empty
• If questions exist: STOP and redirect to /lp:clarify

Workflow

1. Validate spec readiness:

   If open_questions > 0:
       ERROR: Spec has unresolved questions. Use /lp:clarify first.
   

2. Mark spec as APPROVED

3. Generate task file: specs/{feature-slug}.tasks.md

4. Break down by component:

   • Group tasks by logical component/module
   • Each task = one logical unit (not TDD-granular)
   • TDD practice enforced during /lp:run-task, not here

5. Add task metadata:

   • Link back to spec
   • Context summary
   • Acceptance criteria per task

6. Final review:

   • Present task list to user
   • Ask: "Any tasks missing or need splitting?"

Task Granularity

Tasks should be high-level logical units:

• "Implement authentication middleware"
• "Create user model and repository"
• "Add API endpoints for user CRUD"

TDD cycle (Red-Green-Refactor) happens WITHIN each task during /lp:run-task.

---

Phase 5: /lp:run-task - Execute Tasks

Trigger: /lp:run-task [task#] (e.g., /lp:run-task, /lp:run-task 3)

Prerequisites

• Task file must exist: specs/{feature}.tasks.md
• If no task file: STOP and redirect to /lp:tasks

Workflow

1. Load task file and find next unchecked task (or specified task#)

2. Load context:

   • Read linked spec for requirements
   • Read specs/README.md for project overrides

3. Execute with TDD:

   • RED: Write failing test first
   • GREEN: Minimal code to pass
   • REFACTOR: Clean up
   • COMMIT: After each phase

4. Update task file:

   • Mark task as [x] complete
   • Add notes if needed

5. Continue or pause:

   • If more tasks: Ask "Continue to next task?"
   • If blocked: Document blocker, ask for input
   • If all done: Mark spec as COMPLETED

Execution Rules

• No interruptions: If questions arise during execution, the spec was not ready
• Respect hooks: Pre-commit hooks must pass before marking complete

---

Project Configuration: specs/README.md

Override default behaviors per-project:

# Spec Configuration

## Language Override
Primary: golang
Secondary: python

## Conventions
- All specs require security section
- Tasks must include rollback plan
- Use feature branches: feature/{spec-name}

## Templates
Use custom templates from: ./templates/

## Auto-invoke
- Always run /trivy before marking complete

State Management

Spec Status Flow

DRAFT -> APPROVED -> IN_PROGRESS -> COMPLETED
          |              |
          v              v
       (questions?)   (blocked?)
          |              |
          v              v
        DRAFT      IN_PROGRESS

File Structure

project/
└── specs/
    ├── README.md           # Project overrides
    ├── auth-system.md      # Spec (APPROVED)
    ├── auth-system.tasks.md # Task breakdown
    ├── user-dashboard.md   # Spec (DRAFT)
    └── ...

Session Resume

On context compaction or session resume:

1. Check specs/ for files with status IN_PROGRESS
2. Check .tasks.md files for unchecked items
3. Report: "Found in-progress spec: X with Y tasks remaining"
4. Ask: "Continue with /lp:run-task?"

Error Handling

Situation	Response
/lp:tasks with open questions	"Spec has N unresolved questions. Use /lp:clarify first."
/lp:run-task without task file	"No task file found. Use /lp:tasks first."
/lp:clarify without active spec	"No active spec. Use /lp:spec to create one."
Ambiguity during /lp:run-task	"Execution blocked: [issue]. Spec needs refinement. Use /lp:refine."
