Titanium Plan Command

You are creating a structured implementation plan from requirements. Follow this systematic process to break down work into actionable tasks with agent assignments.

MCP Tools Used: This command uses the tt MCP server (Titanium Toolkit) which provides:

mcp__plugin_titanium-toolkit_tt__plan_parser - Generates structured implementation plans from requirements

The tt server wraps Python utilities that use Claude AI to analyze requirements and create detailed project plans with task-to-agent assignments.

Agent Assignment: The plan_parser automatically assigns tasks to appropriate specialized agents based on task type (API work → @api-developer, UI work → @frontend-developer, etc.). These assignments are used by /titanium:work to delegate implementation.

Process Overview

This command will:

Gather and validate requirements
Use Claude (via plan_parser MCP tool) to generate structured plan
Validate plan with vibe-check
Create human-readable documentation
Store plan in Pieces for future reference

Step 1: Gather Requirements

If user provides a file path:

# User might say: /titanium:plan ~/bmad/output/user-auth-prd.md

Use Read tool to read the file
Extract requirements text

If user provides inline description:

# User might say: /titanium:plan
# Then describe: "I need to add JWT authentication with login, register, password reset"

Write description to .titanium/requirements.md using Write tool
Ask clarifying questions if needed:
- What tech stack? (Node.js, Python, Ruby, etc.)
- What database? (PostgreSQL, MongoDB, etc.)
- Any specific libraries or frameworks?
- Security requirements?
- Performance requirements?

Step 2: Generate Structured Plan

Use the plan_parser MCP tool to generate the plan:

mcp__plugin_titanium-toolkit_tt__plan_parser(
  requirements_file: ".titanium/requirements.md",
  project_path: "$(pwd)"
)

This will:

Call Claude with the requirements
Generate structured JSON plan with:
- Epics (major features)
- Stories (user-facing functionality)
- Tasks (implementation steps)
- Agent assignments
- Time estimates
- Task dependencies
Save to .titanium/plan.json
Return the JSON plan directly to Claude

Important: The plan_parser tool needs ANTHROPIC_API_KEY environment variable. If it fails with an API key error, inform the user they need to add it to ~/.env

Step 3: Review the Generated Plan

Read and analyze .titanium/plan.json:

# Read the plan
Read .titanium/plan.json

Check that the plan:

Has reasonable epics (1-5 major features)
Each epic has logical stories (1-5 per epic)
Each story has actionable tasks (2-10 per story)
Agent assignments are appropriate
Time estimates seem realistic
Dependencies make sense

Common issues to watch for:

Tasks assigned to wrong agents (e.g., frontend work to @api-developer)
Missing testing tasks
Missing documentation tasks
Unrealistic time estimates
Circular dependencies

If the plan needs adjustments:

Edit .titanium/requirements.md to add clarifications
Re-run the plan_parser tool
Review again

Step 4: Validate Plan with vibe-check

Use vibe-check to validate the plan quality:

mcp__vibe-check__vibe_check(
  goal: "User's stated goal from requirements",
  plan: "Summary of the generated plan - list epics, key stories, agents involved, total time",
  uncertainties: [
    "List any concerns about complexity",
    "Note any ambiguous requirements",
    "Mention any technical risks"
  ]
)

Example:

mcp__vibe-check__vibe_check(
  goal: "Implement JWT authentication system with login, register, and password reset",
  plan: "2 epics: Backend API (JWT middleware, 3 endpoints, database) and Frontend UI (login/register forms, password reset flow). Agents: @product-manager, @api-developer, @frontend-developer, @test-runner, @security-scanner. Total: 4 hours",
  uncertainties: [
    "Should we use refresh tokens or just access tokens?",
    "Password hashing algorithm not specified - suggest argon2",
    "Rate limiting strategy needs clarification"
  ]
)

Handle vibe-check response:

If vibe-check raises concerns:
- Review the concerns carefully
- Update requirements or plan approach
- Re-run the plan_parser tool with adjustments
- Validate again with vibe-check
If vibe-check approves:
- Continue to next step

Step 5: Create Human-Readable Plan

Write a markdown version of the plan to .titanium/plan.md:

# Implementation Plan: [Project Goal]

**Created**: [Date]
**Estimated Time**: [Total time from plan.json]

## Goal
[User's goal statement]

## Tech Stack
[List technologies mentioned in requirements]

## Epics

### Epic 1: [Epic Name]
**Description**: [Epic description]
**Estimated Time**: [Sum of all story times]

#### Story 1.1: [Story Name]
**Description**: [Story description]
**Tasks**:
1. [Task 1 name] - [@agent-name] - [time estimate]
2. [Task 2 name] - [@agent-name] - [time estimate]

#### Story 1.2: [Story Name]
**Description**: [Story description]
**Tasks**:
1. [Task 1 name] - [@agent-name] - [time estimate]
2. [Task 2 name] - [@agent-name] - [time estimate]

### Epic 2: [Epic Name]
[... repeat structure ...]

## Agents Involved
- **@product-manager**: Requirements validation
- **@api-developer**: Backend implementation
- **@frontend-developer**: UI development
- **@test-runner**: Testing
- **@doc-writer**: Documentation

## Dependencies
[List any major dependencies between epics/stories]

## Next Steps
Ready to execute? Run: `/titanium:work`

Step 6: Store Plan in Pieces

Store the plan in Pieces LTM for future reference:

mcp__Pieces__create_pieces_memory(
  summary_description: "Implementation plan for [project name/goal]",
  summary: "Plan created with [X] epics, [Y] stories, [Z] tasks. Agents: [list agents]. Estimated time: [total time]. Key features: [brief list of main epics]. vibe-check validation: [summary of validation results]",
  files: [
    ".titanium/plan.json",
    ".titanium/plan.md",
    ".titanium/requirements.md"
  ],
  project: "$(pwd)"
)

Example:

mcp__Pieces__create_pieces_memory(
  summary_description: "Implementation plan for JWT authentication system",
  summary: "Plan created with 2 epics, 5 stories, 12 tasks. Agents: @product-manager, @api-developer, @frontend-developer, @test-runner, @security-scanner. Estimated time: 4 hours. Key features: JWT middleware with refresh tokens, login/register/reset endpoints, frontend auth forms, comprehensive testing. vibe-check validation: Plan structure is sound, recommended argon2 for password hashing, suggested rate limiting on auth endpoints.",
  files: [
    ".titanium/plan.json",
    ".titanium/plan.md",
    ".titanium/requirements.md"
  ],
  project: "/Users/username/projects/my-app"
)

Step 7: Present Plan to User

Format the output in a clear, organized way:

📋 Implementation Plan Created

🎯 Goal: [User's goal]

📦 Structure:
- [X] epics
- [Y] stories
- [Z] implementation tasks

⏱️  Estimated Time: [total time]

🤖 Agents Involved:
- @agent-name (role description)
- @agent-name (role description)
- [... list all agents ...]

📁 Plan saved to:
- .titanium/plan.json (structured data)
- .titanium/plan.md (readable format)

✅ vibe-check validated: [Brief summary of validation results]

📝 Key Epics:
1. [Epic 1 name] - [time estimate]
2. [Epic 2 name] - [time estimate]
[... list all epics ...]

---

Ready to execute this plan?

Run: /titanium:work

This will orchestrate the implementation using the plan,
with voice announcements and quality gates throughout.

Important Guidelines

Always:

✅ Use the plan_parser MCP tool (don't try to generate plans manually)
✅ Validate with vibe-check before finalizing
✅ Store the plan in Pieces
✅ Create both JSON (for machines) and Markdown (for humans)
✅ Get user approval before they proceed to /titanium:work
✅ Be specific about agent roles in the summary

Never:

❌ Skip vibe-check validation
❌ Generate plans without using the plan_parser tool
❌ Proceed to implementation without user approval
❌ Ignore vibe-check concerns
❌ Create plans without clear task assignments

Error Handling

If ANTHROPIC_API_KEY is missing:

Error: The plan_parser tool needs an Anthropic API key to generate plans.

Please add your API key to ~/.env:
  echo 'ANTHROPIC_API_KEY=sk-ant-your-key-here' >> ~/.env
  chmod 600 ~/.env

Then restart Claude Code and try again.

If vibe-check is not available:

Warning: vibe-check MCP is not available. Proceeding without quality validation.

Consider setting up vibe-check for AI-powered quality gates:
  1. Create ~/.vibe-check/.env
  2. Add at least one API key (GEMINI_API_KEY, OPENAI_API_KEY, or OPENROUTER_API_KEY)
  3. Restart Claude Code

If requirements are unclear:

The requirements need more detail. Let me ask some questions:

1. [Specific question about tech stack]
2. [Specific question about features]
3. [Specific question about constraints]

Once I have this information, I'll create a detailed plan.

If plan generation fails:

The plan generation failed. This could be due to:
- Invalid requirements format
- API rate limits
- Network issues

Let me try again with simplified requirements.
[Retry with more basic prompt]

Example Usage

Example 1: With BMAD PRD file

User: /titanium:plan ~/bmad/output/user-auth-prd.md

Claude:
- Reads PRD file
- Calls plan_parser tool
- Reviews generated plan
- Validates with vibe-check
- Creates plan.md
- Stores in Pieces
- Presents formatted summary to user

Example 2: With inline description

User: /titanium:plan

Claude: "What would you like to implement?"

User: "Add a search feature to filter products by name and category"

Claude:
- Writes description to .titanium/requirements.md
- Asks: "What's your tech stack?"
User: "React frontend, Node.js backend with PostgreSQL"
- Calls plan_parser tool with complete requirements
- Generates plan with appropriate tech stack
- Validates with vibe-check
- Presents plan to user

Example 3: Complex feature with multiple clarifications

User: /titanium:plan "Build a payment processing system"

Claude: "I need more details:
1. Which payment provider? (Stripe, PayPal, etc.)
2. What types of payments? (One-time, subscriptions, both?)
3. Currency support? (Single, multiple?)
4. Security requirements? (PCI compliance needed?)
5. Refund handling?"

User: "Stripe, one-time payments only, USD, yes PCI compliance, yes refunds"

Claude:
- Writes complete requirements
- Generates comprehensive plan
- vibe-check raises concern about PCI compliance complexity
- Adjusts plan to include @security-scanner more heavily
- Re-validates with vibe-check
- Presents approved plan

Voice Feedback

The voice hooks will automatically announce:

"Starting plan generation" (when script is called)
"Plan created with [X] epics" (when complete)
"vibe-check validation complete" (after validation)

No additional voice calls needed - the hooks handle this automatically.

Next Command

After creating the plan, the user should run:

/titanium:work

This will execute the plan with orchestrated agent coordination.

/titanium-plan
