About plan

The Plan skill is designed to convert validated research into a structured and actionable implementation plan. It addresses the common challenge of translating complex research findings into clear, step-by-step execution strategies. By organizing information from requirements, codebase maps, and potential risks, it ensures that planning is systematic, comprehensive, and traceable. This skill is particularly useful for teams looking to streamline project execution while minimizing uncertainty and oversight during early planning stages.

The core capabilities of the Plan skill include creating task breakdowns with dependencies, guiding architectural decisions, and enforcing critical edge case reviews. It supports structured planning phases, from initial architectural decisions to final verification of the plan, ensuring completeness and feasibility. Users can document edge cases, handle boundary conditions, and capture architectural trade-offs through interactive checkpoints that prompt user input when decisions are ambiguous or require confirmation. The skill also integrates with agent workflows like Claude Code and Codex CLI, providing standardized output directories for easy tracking of planning artifacts.

Typical use cases include software development project planning, feature rollout preparation, and architectural design validation. Target users are software engineers, project managers, and technical leads who need a reliable method to organize tasks, ensure all edge cases are considered, and maintain traceable decision-making throughout a project. It is especially valuable in environments where clarity, accuracy, and structured documentation of implementation plans are critical for team coordination and successful project delivery.

FAQ

How do I start using the Plan skill?

Begin by providing validated research inputs, including requirements, codebase maps, and identified risks. The skill will guide you through structured planning phases and task breakdowns.

Which platforms or agents is this skill compatible with?

The Plan skill is compatible with Claude Code and Codex CLI. It uses AskUserQuestion in Claude Code and records user input directly in Codex CLI, with output directories `.claude/output` and `.codex/output` respectively.

What is the mandatory edge case review phase?

Phase 1.5 requires listing and reviewing all edge cases, such as empty states, error states, boundary conditions, null/zero values, and missing data scenarios. This phase is blocking and must be completed before proceeding to task breakdown.

Can I document architectural trade-offs using this skill?

Yes. The Plan skill includes P-Checkpoints that allow you to capture architecture decisions, scope boundaries, and edge case behaviors through structured user questions and recorded answers.

Are there any limitations I should be aware of?

The skill relies on validated research inputs and user feedback for ambiguous decisions. It does not generate implementation code or infer requirements that are not provided in the source research.
