Where are the plan files stored?

Plans are saved as Markdown files in the $CODEX_HOME/plans directory, defaulting to ~/.codex/plans if the environment variable is not set.

Does this skill modify my repository's source code?

No, the Codex Task Planner is designed to read the repository for context but will only write files to its designated plans directory to avoid unintended code changes.

How do I find existing plans I've created?

The skill includes discovery features that allow you to search, list, and read plan summaries based on their name and description metadata.

Can I create architectural overviews instead of task lists?

Yes, the skill supports two distinct templates: 'Implementation' for actionable task lists and 'Overview' for documenting system flows and architecture.

Productivity & Workflow

Generates and manages structured implementation plans and architectural overviews for complex software development tasks.

Codex Task Planner is a specialized Claude Code skill designed to bring structure to complex coding projects by drafting, storing, and managing detailed plans. It allows developers to create either actionable implementation checklists or high-level system overviews, complete with requirements, scope, and risk assessments. By maintaining a dedicated plans directory outside the main codebase, it ensures that project intent and execution steps are documented and easily accessible, helping to reduce ambiguity and streamline the development lifecycle from initial discovery to final validation.

Key Features

01Persistent local storage of plans in Markdown format with YAML frontmatter metadata.

02Support for high-level architectural overviews and system flow documentation.

031 GitHub stars

04Context-aware repo scanning to identify constraints, languages, and frameworks before planning.

05Integrated plan management including discovery, updates, and deletion through helper scripts.

06Automated generation of structured implementation plans with action items and risk assessments.

Use Cases

01Documenting complex system architectures and data flow diagrams for team onboarding.

02Drafting a step-by-step migration plan for legacy codebases with clear validation checkpoints.

03Managing a technical backlog by creating structured plans for future feature implementations.
