Without the toolkit
- You rewrite planning prompts and acceptance criteria for every task.
- You move between scattered notes, review checklists, and release steps by hand.
- You rely on general-purpose agents that do not know your development workflow.

Why
The workflow gets lighter when the toolkit carries the repeatable work.
With the toolkit
ywc-planandywc-task-generatorturn rough goals into implementation-ready work.ywc-code-genandywc-impl-reviewkeep build, review, and verification loops explicit./ywc-agenticroutes complex work through a capped, review-gated loop — up to three automated iterations withywc-impl-reviewfolded in before anything merges.
How it works
An opinionated pipeline, not a skill grab-bag.
Most of the 46 skills chain into one sequence instead of standing alone as independent prompts you have to order yourself.
01 Plan
ywc-planturns a rough goal into a spec and routes it to the right size of flow.02 Converge
ywc-spec-readyloops planning and validation until the spec is done, for anything beyond a small change.03 Decompose
ywc-task-generatorbreaks the spec into dependency-safe tasks with a parallel-execution graph.04 Execute
The executor implements each task — review, PR, and merge folded in via
--review.05 Verify
ywc-gen-testcasegenerates a QA test sheet per PR, ready for manual sign-off.
Or skip straight to /ywc-agentic.
One goal in, a capped review-gated loop out — up to three automated Plan → Execute → Evaluate → Repeat iterations with ywc-impl-review folded in before anything merges.

FAQ
FAQ
What is this?
`ywc-agent-toolkit` is a public toolkit of skills and custom agents for Claude Code and Codex. It helps you run repeatable development workflows from planning through release.
What are the installation requirements?
Plugin-marketplace and Codex-plugin installation have no prerequisites. Use the commands above, then install from the matching plugin UI or marketplace.
What is the cost or token impact?
The toolkit itself is open source and does not add a paid service. Token usage depends on how often you invoke the skills and agents in Claude Code or Codex.
Does it work with both Claude Code and Codex?
Yes. Both tools receive 46 skills. Claude Code includes 13 custom agents, while Codex includes 8 custom agents.
Do I need to clone the repository?
No for the paths covered on this page. Claude Code marketplace installation and Codex plugin marketplace installation are designed to install without manual cloning.
Can I keep using my existing workflow?
Yes. The toolkit adds reusable skills such as `ywc-plan`, `ywc-code-gen`, and `ywc-impl-review`; it does not require a backend, account, or project migration.
What can the toolkit change without asking me?
`ywc-merge-dependabot` can auto-merge dependency PRs, and `ywc-finish-branch` can merge and delete branches once its checks pass. `ywc-agentic` runs up to three automated iterations with `ywc-impl-review` folded in before anything merges. Every one of these is a skill you invoke — none of it runs unless you call it.
Do I need anything besides Claude Code or Codex?
Plugin-marketplace installation itself has no prerequisites. Using certain skills afterward does: `python3` ≥ 3.9 (≥ 3.11 for hooks) for skills like `ywc-parallel-executor` and `ywc-finish-branch`, and the `gh` CLI for PR- and release-based skills.
Does this modify my shell or tool behavior?
Only if you install the optional Claude Code hooks. They add guardrails like blocking dangerous shell commands and blocking access to `.env`/SSH-key files — you can skip them entirely and use only the skills.
How is this different from a generic skill collection?
Most of the 46 skills are wired into one opinionated pipeline (plan → spec → tasks → execute → test) instead of standing alone as prompts you sequence yourself, and confirmed defects feed a review-learnings loop that tightens future reviews automatically.
Can I contribute a skill?
Yes. `ywc-skill-author` documents the conventions, and CONTRIBUTING.md covers bug reports, new skills, and translations.
