Lerianstudio Ring Writing Plans

Writing Plans

Overview

This skill dispatches a specialized agent to write comprehensive implementation plans for engineers with zero codebase context.

Announce at start: "I'm using the ring:writing-plans skill to create the implementation plan."

Context: This should be run in a dedicated worktree (created by ring:brainstorming skill).

The Process

Step 1: Dispatch Write-Plan Agent

Dispatch via Task(subagent_type: "ring:write-plan") with:

• Instructions to create bite-sized tasks (2-5 min each)
• Include exact file paths, complete code, verification steps
• Save to docs/plans/YYYY-MM-DD-<feature-name>.md

Step 2: Validate Plan

After the plan is saved, validate it:

python3 default/lib/validate-plan-precedent.py docs/plans/YYYY-MM-DD-<feature>.md

Interpretation:

• PASS → Plan is safe to execute
• WARNING → Plan has issues to address
  • Review the warnings in the output
  • Update plan to address the issues
  • Re-run validation until PASS

Step 3: Ask User About Execution

Ask via AskUserQuestion: "Execute now?" Options:

1. Execute now → ring:subagent-driven-development
2. Parallel session → user opens new session with ring:executing-plans
3. Save for later → report location and end

Why Use an Agent?

Context preservation (reading many files keeps supervisor clean) | Model power (comprehensive planning) | Separation of concerns (supervisor orchestrates, agent plans)

What the Agent Does

Explore codebase → identify files → break into bite-sized tasks (2-5 min) → write complete code → include exact commands → add review checkpoints → verify Zero-Context Test → save to docs/plans/YYYY-MM-DD-<feature>.md → report back

Requirements for Plans

Every plan: Header (goal, architecture, tech stack) | Verification commands with expected output | Exact file paths (never "somewhere in src") | Complete code (never "add validation here") | Bite-sized steps with verification | Failure recovery | Review checkpoints | Zero-Context Test | Recommended agents per task

Multi-Module Task Requirements

If TopologyConfig exists (from pre-dev research.md frontmatter or user input):

Each task MUST include:

• Target: backend | frontend | shared
• Working Directory: Resolved path from topology configuration
• Agent: Recommended agent matching the target

Task Format with Target:

## Task 3: Create User Login API

**Target:** backend
**Working Directory:** packages/api
**Agent:** ring:backend-engineer-golang

**Files to Create/Modify:**
- `packages/api/internal/handlers/auth.go`
- `packages/api/internal/services/auth_service.go`

...rest of task...

Target Assignment Rules:

Working Directory Resolution:

Agent Selection

Backend Tasks

Frontend Tasks (api_pattern aware)

Read api_pattern from topology configuration to determine correct agent:

Decision Logic for Frontend Tasks

def get_frontend_agent(task, topology):
    api_pattern = topology.get('api_pattern', 'direct')

    if api_pattern == 'direct':
        return 'ring:frontend-engineer'

    if api_pattern == 'bff':
        if is_bff_task(task):  # API routes, aggregation, transformation
            return 'ring:frontend-bff-engineer-typescript'
        else:  # UI components, pages
            return 'ring:frontend-engineer'

    return 'ring:frontend-engineer'  # Default for 'other'

def is_bff_task(task):
    bff_indicators = [
        'API route', 'api route', '/api/',
        'aggregat', 'transform', 'BFF',
        'external service', 'backend service',
        'data layer', 'HTTP client'
    ]
    return any(ind in task.description for ind in bff_indicators)

Infrastructure and Other Tasks

Task Format with api_pattern

When TopologyConfig includes api_pattern, include it in task metadata:

## Task 3: Aggregate Dashboard Data

**Target:** frontend
**Working Directory:** packages/web
**API Pattern:** bff
**Agent:** ring:frontend-bff-engineer-typescript

**Files to Create/Modify:**
- `packages/web/app/api/dashboard/route.ts`
- `packages/web/lib/services/dashboard-aggregator.ts`

...rest of task...

Execution Options Reference

Required Patterns

This skill uses these universal patterns:

• State Tracking: See skills/shared-patterns/state-tracking.md
• Failure Recovery: See skills/shared-patterns/failure-recovery.md
• Exit Criteria: See skills/shared-patterns/exit-criteria.md
• TodoWrite: See skills/shared-patterns/todowrite-integration.md

Apply ALL patterns when using this skill.

Blocker Criteria

STOP and report if:

Cannot Be Overridden

The following requirements CANNOT be waived:

• Design phase MUST be complete before creating implementation plan
• Plan validation script MUST pass before execution
• All tasks MUST include exact file paths, never "somewhere in src"
• All tasks MUST include complete code examples, never placeholders
• Each task MUST specify recommended agent
