skills

Agent skills for Claude Code and other agents that read SKILL.md.

Skills

creating-notion-page

Create a Notion page in your private space by default, then review it as a first-time reader would.

Depends on:

• Notion MCP server

commit

Select hunks, verify the diff that will land, and create a signed commit outside the sandbox — with jj in a jujutsu repository, git otherwise.

Depends on:

• git-surgeon (git repositories only)
• jj-surgeon (jj repositories only)
• good-writing
• review

good-writing

Write concise, precise prose: docs, PR descriptions, commit messages, blog posts.

Depends on:

• yomiyasu (optional)

grilling

Interview you about a plan, decision, or idea in rounds, one frontier of questions at a time. In Claude Code the questions arrive as its prompt UI. Adapted from mattpocock/skills' grilling.

Depends on: none

initializing-web-project

Scaffold a web project on a Nix devshell with Bun, TypeScript, and Biome, plus optional libraries.

Depends on: none

next-dev

Verify Next.js changes without clobbering a running next dev server.

Depends on:

• agent-browser (optional)

review

Review a diff, commit, or pull request and fix what the review finds. So far the only rule sends code comments through writing-code-comments.

Depends on:

• writing-code-comments

write-like-yongju

Write Japanese in your own voice: comments and messages to others, issue and PR bodies, and memos.

Depends on:

• good-writing

writing-code-comments

Write code comments and docstrings that explain why, not what.

Depends on:

• good-writing

External dependencies

Install these alongside the skills that need them. A skill whose dependency is missing will still load, but the steps that call the dependency won't work.

git-surgeon

Non-interactive, hunk-level git staging. Provides both the git-surgeon CLI and its skill. See raine/git-surgeon.

jj-surgeon

Non-interactive, hunk-level jujutsu operations. Provides both the jj-hunk-tool CLI and the jj-surgeon skill. See mvzink/jj-hunk-tool.

agent-browser

Browser automation CLI for agents. Provides both the agent-browser CLI and its skill. See vercel-labs/agent-browser.

yomiyasu

Revises Japanese prose generated by AI. good-writing uses it only when the output is Japanese, and works without it otherwise. See nanaism/yomiyasu.

Installation

Install as a Claude Code plugin:

/plugin marketplace add sei40kr/skills
/plugin install sei40kr-skills@sei40kr

The plugin installs every skill above. Install the required external dependencies separately.
