Planner
Create structured, orchestrator-ready plans for multi-task projects.
Source: Based on am-will/codex-skills
Pairs with: task-orchestrator skill for execution
Quick Start
Load the full planner prompt from prompts/planner.md and follow its process:
- •Phase 0: Clarify requirements (ask up to 5 targeted questions)
- •Phase 1: Research & understand the codebase
- •Phase 2: Create detailed plan with sprints, tasks, acceptance criteria
- •Phase 3: Subagent review of the plan
- •Phase 4: Save the plan file
Key Principles
Task Atomicity
Each task must be:
- •Atomic and committable — small, independent pieces of work
- •Specific and actionable — not vague
- •Testable — include tests or validation method
- •Located — include file paths and code locations
Bad vs Good Task Breakdown
❌ Bad: "Implement Google OAuth"
✓ Good:
- •"Add Google OAuth config to environment variables"
- •"Install and configure passport-google-oauth20 package"
- •"Create OAuth callback route handler in src/routes/auth.ts"
- •"Add Google sign-in button to login UI"
Sprint Structure
Each sprint must:
- •Result in a demoable, runnable, testable increment
- •Build on prior sprint work
- •Include clear demo/verification checklist
Plan Template
markdown
# Plan: [Task Name] **Generated**: [Date] **Estimated Complexity**: [Low/Medium/High] ## Overview [Brief summary of what needs to be done and the general approach] ## Prerequisites - [Dependencies or requirements that must be met first] - [Tools, libraries, or access needed] - [Tooling limitations, e.g., browser relay/CDP restrictions] ## Sprint 1: [Sprint Name] **Goal**: [What this sprint accomplishes] **Demo/Validation**: - [How to run/demo this sprint's output] - [What to verify] ### Task 1.1: [Task Name] - **Location**: [File paths or components involved] - **Description**: [What needs to be done] - **Perceived Complexity**: [1-10] - **Dependencies**: [Any previous tasks this depends on] - **Acceptance Criteria**: - [Specific, testable criteria] - **Validation**: - [Test(s) or alternate validation steps] ### Task 1.2: [Task Name] [...] ## Sprint 2: [Sprint Name] [...] ## Testing Strategy - [How to test the implementation] - [What to verify at each sprint] ## Potential Risks - [Things that could go wrong] - [Mitigation strategies] ## Rollback Plan - [How to undo changes if needed]
Execution
Once plan is ready, hand off to the parallel-task executor:
code
Please execute parallel-task.md against my-plan.md
Or invoke directly:
"Run all unblocked tasks in plan.md using parallel subagents. Keep looping until all tasks are complete."
