Arvorco Relentless Plan

Technical Implementation Plan Generator

Create detailed technical plans that translate feature specifications into implementation designs.

SpecKit Workflow

This skill is Step 2 of 6 in the Relentless workflow:

specify → plan → tasks → analyze → implement

What flows from spec:

• User requirements → technical approach
• Routing preference → carried forward
• Acceptance criteria → test specifications

What flows to tasks:

• Technical approach → implementation breakdown
• Test specifications → TDD acceptance criteria

TDD is MANDATORY

The technical plan MUST include concrete test specifications:

• Test file locations (where tests will live)
• Test class/function names (what to create)
• Mock/fixture requirements (what test data needed)
• Coverage targets per component

The agent MUST write tests BEFORE implementation code.

This is non-negotiable. Plans without test specifications are incomplete.

The Job

1. Read the feature specification (spec.md)
2. Extract and validate routing preference (Step 2)
3. Read project constitution for technical constraints
4. Generate technical architecture and implementation plan
5. Include complete test specifications
6. Validate against quality gates
7. Save to plan.md in the feature directory

Step 1: Locate Feature Files

Find the current feature directory:

• Look in relentless/features/ for the most recent feature
• Or ask user which feature to plan
• Verify spec.md exists

Step 2: Extract Routing Preference

1. Read spec.md and extract routing preference
2. If missing, DEFAULT to: auto: good | allow free: yes
3. Validate format is correct
4. Carry forward to plan.md metadata
5. Update progress.txt with routing decision

Example:

Spec says: **Routing Preference**: auto: genius | allow free: no
Plan carries: **Routing Preference**: auto: genius | allow free: no

Step 3: Load Context

Read these files:

1. relentless/constitution.md - Project governance and technical standards
2. relentless/features/NNN-feature/spec.md - Feature requirements
3. Project README or docs for tech stack information

Note all MUST and SHOULD rules from constitution - these are quality gates.

Step 4: Generate Technical Plan

Using the template at templates/plan.md, create a plan with:

Required Sections:

1. Technical Overview

• Architecture approach
• Key technologies to use (from constitution/existing stack)
• Integration points
• Routing preference carried from spec (auto mode or harness/model)

2. Data Models

• Database schemas
• Entity relationships
• Field definitions with types
• Indexes and constraints

3. API Contracts

• Endpoints and methods
• Request/response formats
• Authentication requirements
• Error responses

4. Implementation Strategy

• Phase breakdown
• Dependencies between components
• Integration approach

5. Test Specifications (MANDATORY)

• Test file structure
• Unit test table (component → test file → functions)
• Integration test table (flow → test file → scenarios)
• Mock requirements
• Coverage targets (minimum 80%)

6. Security Considerations

• Authentication/authorization
• Data validation
• Security best practices
• Compliance requirements

7. Rollout Plan

• Deployment strategy
• Migration requirements (if any)
• Monitoring and observability
• Rollback plan

Step 5: Ensure Constitution Compliance

Validate the plan against constitution:

Quality Gates Check

Before completing the plan, validate:

• TDD approach defined - test specs with file locations
• Quality commands identified - typecheck, lint, test
• Routing preference carried from spec
• All MUST rules from constitution addressed
• No any types planned in TypeScript
• Error handling strategy defined

MUST rules: Required, plan must follow these SHOULD rules: Best practices, document any deviations

If plan violates MUST rules, revise until compliant.

If plan generates any doubts, interview the user about them with insightful questions to improve the plan.

Step 6: Save & Validate

1. Save plan to relentless/features/NNN-feature/plan.md
2. Run the validator to ensure plan.md is correctly formatted:

   .claude/skills/validators/scripts/validate-plan.sh "relentless/features/NNN-feature/plan.md"
   

   • If validation fails, fix the errors and re-run
   • Warnings are acceptable but should be reviewed
3. Update progress.txt with plan creation timestamp and routing info
4. Report:
   • Plan location
   • Key technical decisions
   • Test specifications summary
   • Constitution compliance: PASS/FAIL
   • Validation: PASS/FAIL
   • Routing preference: [carried value]
   • Next step: /relentless.tasks

# Technical Implementation Plan: User Authentication

**Routing Preference**: auto: good | allow free: yes

## Technical Overview

**Architecture:** Three-tier (API, Service, Data)
**Stack:** Node.js, TypeScript, PostgreSQL
**Authentication:** JWT tokens with refresh mechanism

## Data Models

### User Table
\`\`\`sql
CREATE TABLE users (
  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
  email VARCHAR(255) UNIQUE NOT NULL,
  password_hash VARCHAR(255) NOT NULL,
  confirmed BOOLEAN DEFAULT FALSE,
  created_at TIMESTAMP DEFAULT NOW(),
  updated_at TIMESTAMP DEFAULT NOW()
);

CREATE INDEX idx_users_email ON users(email);
\`\`\`

## API Contracts

### POST /api/auth/register
**Request:**
\`\`\`json
{
  "email": "user@example.com",
  "password": "password123"
}
\`\`\`

**Response (201):**
\`\`\`json
{
  "id": "uuid",
  "email": "user@example.com",
  "message": "Confirmation email sent"
}
\`\`\`

## Test Specifications (MANDATORY)

### Test File Structure
\`\`\`
tests/
├── unit/
│   ├── auth/
│   │   ├── password.test.ts
│   │   └── email-validation.test.ts
│   └── token/
│       └── jwt.test.ts
├── integration/
│   └── auth/
│       ├── register.test.ts
│       └── login.test.ts
└── e2e/
    └── auth-flow.test.ts
\`\`\`

### Unit Tests
| Component | Test File | Functions to Test |
|-----------|-----------|-------------------|
| Password | `tests/unit/auth/password.test.ts` | hashPassword, verifyPassword |
| Email | `tests/unit/auth/email-validation.test.ts` | validateEmail |
| JWT | `tests/unit/token/jwt.test.ts` | generateToken, verifyToken |

### Integration Tests
| Flow | Test File | Scenarios |
|------|-----------|-----------|
| Register | `tests/integration/auth/register.test.ts` | success, duplicate email, invalid input |
| Login | `tests/integration/auth/login.test.ts` | success, wrong password, unconfirmed |

### Mock Requirements
- Database mock (in-memory or test container)
- Email service mock (no actual sends)
- Time mock for token expiration tests

### Coverage Targets
- Unit: 90% minimum (critical auth code)
- Integration: All happy paths + error paths
- E2E: Complete registration and login flow

## Constitution Compliance

**MUST Rules Checked:**
- [x] TDD is mandatory - test specs defined above
- [x] Quality gates defined - typecheck, lint, test commands
- [x] Routing preference carried from spec
- [x] No `any` types planned
- [x] Error handling strategy defined

**If any MUST rule cannot be satisfied, document the exception and remediation plan.**

Notes

• Plan bridges WHAT (spec) to HOW (implementation)
• Include specific technologies and patterns
• Must comply with constitution
• Detailed enough for task generation
• Interview user if you have any doubts or suggestions
• Test specifications are mandatory - no tests = incomplete plan
• Routing preference must be carried forward from spec
