Skill Claude CodeCodex
A Japanese-language workflow for converting requirements and edge cases into acceptance criteria. Acceptance criteria are checkable conditions that define when a feature is finished.
Skill Claude CodeCodex
A review process that compares completed implementation work with its acceptance criteria. Acceptance criteria are the specific conditions a feature or change must meet before it is accepted.
Skill Claude CodeCodex
A guided conversation that turns an idea or unclear request into a structured input package for a planned coding task. It is designed for the brainstorming stage of the PlanGate workflow.
Skill Claude CodeCodex
An implementation workflow for building approved software plans with test-driven development, or TDD, where tests help define the expected behaviour before and during coding. It applies the execution phase of the PlanGate process after approval.
Skill Claude CodeCodex
A planning workflow that turns an approved feature package into a work plan, task list, and test cases. It is part of PlanGate, a process for moving from requirements to implementation in controlled stages.
Skill Claude CodeCodex
An acceptance-testing and handoff workflow for the PlanGate software process. It checks the completed implementation and produces a handoff document for preparing a pull request.
Skill Claude CodeCodex
A runbook for one cycle of an AI-assisted change review: collect files, run checks, make a decision, save a record, and follow the result.
Skill Claude CodeCodex
A design-planning aid that turns an agreed specification into a proposed software structure, including modules, data movement, state, failures, and testing.
Skill Claude CodeCodex
A conversational design process that turns a rough feature idea or unclear requirement into an approved design document. It asks focused questions and considers several implementation approaches before code is written.
Skill Claude CodeCodex
A task-size check that decides whether a proposed piece of work is too broad and should be split before planning starts.
Skill Claude CodeCodex
A guide for dividing development work among multiple coding agents and combining their results. It covers when to delegate, how to split tasks, and which independent roles can work in parallel.
Skill Claude CodeCodex
A planning aid that breaks a large feature into a smallest useful first version, called an MVP, and later phases.
Skill Claude CodeCodex
A project-context summary built from AGENTS.md, related documents, the request, and selected code. AGENTS.md is a file that records project rules and working instructions.
Skill Claude CodeCodex
A compact, structured brief for giving a coding task to another agent. It includes the allowed files, relevant requirements, existing tests, limits, commands, and excluded work.
Skill Claude CodeCodex
A pre-coding design review for high-risk tasks that produces and evaluates a structured design document before implementation.
Skill Claude CodeCodex
A multi-stage tool for inspecting code changes and producing a structured audit report. A diff is the record of changes between two versions of a codebase.
Skill Claude CodeCodex
A systematic list of boundary cases and unusual situations a feature may encounter. It covers inputs, failures, timeouts, retries, and simultaneous actions.
Skill Claude CodeCodex
An evidence record for completion claims such as “fixed” or “tests passed.” TDD, or test-driven development, is a practice of first seeing a test fail, then making it pass, and checking it again after cleanup.
Skill Claude CodeCodex
A workflow skill for implementing a small feature from a design document, with tests, self-review, recorded known issues, and separate commits.
Skill Claude CodeCodex
A request classifier that assigns a software-development request to one of eight intent categories and returns structured JSON. It bases the classification on signals explicitly present in the request.
Skill Claude CodeCodex
A handoff note that records known bugs, compromises, and ideas left for a later version. It gives the next person enough context to continue the work.
Skill Claude CodeCodex
A short instruction packet for resuming a coding task locally with Codex CLI or Claude Code. It also helps one tool or agent hand work to another.
Skill Claude CodeCodex
A guide for resolving file references when a cloud-based coding task cannot find the repository's normal instructions. It defines where to look for the authoritative files.
Skill Claude CodeCodex
A requirements review that checks concerns beyond visible features, including performance, maintainability, security, accessibility, and system monitoring. It is designed for a Japanese workflow phase called requirement expansion.
