Jung von Matt TECH
Agent Toolkit
Your agents deserve better skills. A reusable skill pack that takes work from raw idea to merged pull request — with a human in the loop at every door that matters.
npx skills add jungvonmatt/agent-toolkit
Works with Claude Code, Copilot, Cursor, Codex, Cline, and more.
One ticket in.
One reviewed pull request out.
Every skill does one job and hands a concrete artifact to the next one: a ticket, a plan, reviewed commits, a review verdict. You can chain the whole flow, or pick the single step you need today.
All skills are namespaced under jvm-skills, so they do not collide with other skill packs.

4 · Open the PR and review
Ask for a pull request and its description is written automatically. Then review for merge readiness — or let a scheduled task do a first pass over every open PR.
/jvm-skills:pr-review
Slash commands shown for Claude Code. In other agents, ask in plain words — "start ticket SHOP-1234" — and the matching skill loads.
The skills
Twelve skills
- Flow
write-ticketTurns a raw idea, bug report, or feature request into a development-ready ticket and publishes it to your tracker.
- Flow
start-ticketFetches a ticket, pulls design specs, explores the codebase, pressure-tests the requirement, and writes a plan.
- Flow
implementExecutes a plan task by task, pausing for a human review of the diff before every commit.
- Auto
pr-descriptionWrites a concise PR/MR description with a small visual, before/after evidence, and the merge danger.
- Flow
pr-reviewReviews a PR against a target branch with severity-ranked findings, ticket traceability, accessibility, and performance checks.
- Flow
scheduled-pr-reviewRuns an unattended first-pass review over all open PRs/MRs from a scheduled task, round after round.
- Auto
writing-testsEnforces behavior-first, mutation-sensitive tests that query by role or test ID, never by class name.
- Auto
technical-writingComments that say why, one Diátaxis mode per page, Simplified Technical English, and a cut test.
- A11y
voiceover-checkDrives the real macOS VoiceOver and compares what it says with what the user must hear.
- Insight
repo-diagnosticsGit-based churn hotspots, bus factor, bug clusters, and velocity — before you read any code.
- Design
jvm-designBootstraps the Jung von Matt CI 2026 design system into a project. This page is built with it.
- Design
design-mdReverse-engineers a design system from Figma, a website, a screenshot, or tokens into a DESIGN.md.
