Create implementation plans with explicit task dependencies optimized for parallel agent execution. This skill can be ran inside or outside of Plan Mode.
Core Principles
Explore Codebase: Investigate architecture, patterns, existing implementations, dependencies, and frameworks in use.
Fresh Documentation First: Use Context7 for ANY external library, framework, or API before planning tasks
Ask Questions: Clarify ambiguities and seek clarification on scope, constraints, or priorities throughout the planning process. At any time.
Explicit Dependencies: Every task declares what it depends on, enabling maximum parallelization
Atomic Tasks: Each task is independently executable by a single agent
Review Before Yield: A subagent reviews the plan for gaps before finalizing
Process
1. Research
Codebase investigation:
Architecture, patterns, existing implementations
Dependencies and frameworks in use
1a. Optional: Stop to Clarification Questions
If the architecture is unclear or missing STOP AND YIELD to the user, and request user input (AskUserQuestions) before moving on. Always offer recommendations for clarification questions.
If architecture is present, skip 1a and move onto next step.
2. Documentation
Documentation retrieval (REQUIRED for external dependencies):
Use Context7 skill or MCP to fetch current docs for any libraries/frameworks or APIs that are or will be used in project. If Context7 is not available, use web search.
This ensures version-accurate APIs, correct parameters, and current best practices.
3. STOP and Request User Input
When anything is unclear or could reasonably be done multiple ways:
Stop and ask clarifying questions immediately
Do not make assumptions about scope, constraints, or priorities
Questions should reduce risk and eliminate ambiguity
Always offer recommendations for clarification questions.
Use request_user_input or AskUserQuestion tool if available.
4. Create Dependency-Aware Plan
Structure the plan with explicit task dependencies using this format:
Task Dependency Format
Each task MUST include:
id: Unique identifier (e.g., T1, T2.1)
depends_on: Array of task IDs that must complete first (empty [] for root tasks)
Tasks with empty/satisfied dependencies can run in parallel (T1, T2 above).
4. Save Plan
Save to <topic>-plan.md in the CWD.
5. Subagent Review
After saving, spawn a subagent to review the plan:
Review this implementation plan for:
1. Missing dependencies between tasks
2. Ordering issues that would cause failures
3. Missing error handling or edge cases
4. Gaps, holes, gotchas.
Provide specific, actionable feedback. Do not ask questions.
Plan location: [file path]
Context: [brief context about the task]
If the subagent provides actionable feedback, revise the plan before yielding.
