Skill Claude CodeCodex
An index of agent definitions in a repository, including guides for triage, document review, document updates, and test-driven development (TDD), a practice of writing tests before implementation.
Agent
A task-sizing step that labels work as small, medium, or needing multiple sessions before detailed planning begins.
Agent
A document and plan review agent that checks whether requirements are covered, the work is practical, supported by industry or community evidence, and safe.
Agent
A documentation-updating agent that scans recent code changes, or a specified range of changes, and updates affected files such as README files, documentation, and code maps. It returns a change manifest for review.
Agent
A guide to test-driven development, or TDD: writing a test that fails, adding code to make it pass, and then improving the code. It is intended to be used before new features or bug fixes and includes an 80% code-coverage threshold.
Skill Claude CodeCodex
A retrospective cleanup process for previously learned skills.
Skill Claude CodeCodex
A development-planning skill that inventories available resources and uses a planning agent to create a detailed implementation plan as a Markdown file in plans/active/.
Skill Claude CodeCodex
An independent process for checking evidence behind a technical decision or practice across research, industry standards, best practices, and community opinions, including opposing views.
Skill Claude CodeCodex
A fact-checking gate for reports produced by coding workflows such as pull-request and security reviews.
Skill Claude CodeCodex
A visual checking process for comparing Figma designs with local web implementations. Figma is a tool for creating interface designs, while a screenshot diff compares images to find visual changes.
Skill Claude CodeCodex
A skill that creates a self-contained handoff prompt summarizing a conversation’s goal, progress, decisions, and unfinished work.
Skill Claude CodeCodex
A quality-checking skill for evaluating one learned skill with three tests: structure, when it activates, and what happens when parts are removed.
Skill Claude CodeCodex
A workflow that reads requirements from a Notion page and connects them to a design implementation plan. Notion is a collaborative app for storing documents and project information.
Skill Claude CodeCodex
A procedure for moving completed plans from an active folder to a completed folder, while recording verification results and the completion time.
Skill Claude CodeCodex
A Python state machine that follows the dependency graph in a plan.md file. A dependency graph shows which tasks must be completed before others can start.
Skill Claude CodeCodex
A skill for operating web browsers with Playwright while keeping a person involved. It can pause before important actions that need human approval.
Skill Claude CodeCodex
A pull-request acceptance workflow that checks a preview, captures screenshots, visually reviews them, and posts pass-or-fail evidence as a comment.
Skill Claude CodeCodex
A workflow for finishing repository work and opening or updating a pull request. A pull request is a proposed code change that others can review before it is merged.
Skill Claude CodeCodex
An automated workflow that takes one or more Notion work-ticket links and works each ticket in its own code workspace. It checks how to reproduce the problem, investigates the cause, applies a fix, opens a pull request, and reports the results.
Skill Claude CodeCodex
A skill for managing learned skills, including deciding which ones to retire, restore, or query. It uses results from removal experiments and a four-part analysis from skills-ecosystem-eval.
Skill Claude CodeCodex
A knowledge-base update workflow described in Chinese. It runs document updates, reviews, context organisation, and pattern extraction in sequence so changes from a work session can be recorded.
Skill Claude CodeCodex
An iterative skill for checking technical claims through several kinds of evidence, including academic research, industry standards, best practices, and community criticism. It uses repeated review rounds and two independent reviewers to reach a verdict.
Skill Claude CodeCodex
A browser-testing workflow that repeatedly checks a web page, fixes failures, and checks it again using Playwright. Playwright is a tool for controlling a real browser in automated tests.
Skill Claude CodeCodex
A skill for managing Git worktrees throughout their lifecycle. A worktree is a separate working folder connected to the same Git repository.
