Agent

Command

What it does

changelog-agent

/cadenza:changelog

Collects merged PRs since the last release, groups them by user impact, and writes a PO-ready changelog draft

pr-agent

/cadenza:pr

Reads your branch commits and diffs, then writes a structured PR description — without pushing anything

test-writer

/cadenza:test

Discovers your project's test conventions, then authors PHPUnit unit and integration tests for PHP source files

retrospective-agent

/cadenza:retrospective

Scans completed pipeline runs, surfaces DOD pass rates and loop-back patterns, and suggests concrete AGENTS.md learnings

(built-in)

/cadenza:commit

Analyses changed files, groups them into atomic commits with generated messages, then offers to push

/cadenza:changelog [v1.2.3]

Generate a PO-ready changelog from merged PRs

/cadenza:pr

Write a PR description for the current branch

/cadenza:test [path/to/File.php]

/cadenza:retrospective [date-from date-to]

Analyse completed pipeline runs and surface learnings

/cadenza:commit [without <file>]

Atomic commits with generated messages, then offer to push

Standalone solos. No orchestra required.

Utility agents that each have one job — and do it well, with no pipeline, no orchestration, and no ceremony.

What Is Cadenza?

In a concerto, the cadenza is the moment the orchestra pauses and a single instrument plays alone — free, expressive, complete on its own terms.

Cadenza is a Claude Code plugin built on that same idea. It contains specialist agents, each handling one task: generating changelogs, writing PR descriptions, authoring PHPUnit tests, and producing retrospective reports. No pipeline. No spec. No twelve-agent handoff chain. Just ask, and it's done.

Use Cadenza on its own for projects that don't need a full delivery pipeline. Or pair it with Maestro — both plugins share the same config schema and coexist without conflict.

Install

/plugin install cadenza@wp-media

Then add a config file to your project:

// .claude/cadenza.json
{
  "ai": {
    "repo":               "my-org/my-plugin",
    "temp_root":          ".cadenza",
    "display_name":       "My Plugin",
    "architecture_skill": "my-plugin-architecture"
  }
}

That's it. All agents are ready.

The Soloists

Each one performs alone.

One Config, Any Project

Every agent reads .claude/cadenza.json — a single file committed in your repo. The agents live in the plugin. The identity lives in the config.

Cadenza plugin (installed once)        Your projects

When Cadenza ships a new version, every project picks it up on the next Claude session — no action needed.
