Causa skills

A Claude Code plugin providing engineering skills to design, implement, document, and release features built on the Causa framework.

Skills

Skill	Purpose
build-feature	Orchestrate end-to-end delivery, invoking the skills below in order.
design-model	Design entity and event schemas.
design-api-http	Design HTTP APIs (OpenAPI) and DTOs.
design-api-firestore	Design Firestore collections and security rules.
design-state	Design Spanner schemas, indexes, and state objects.
plan-implementation	Plan services and controllers.
plan-tests	Plan contract and unit tests.
implement	Write the code and tests from the plans.
design-scenario	Author end-to-end test scenarios.
design-timeline	Visualize events from several sources (service logs, event topics) on one time axis.
document	Document the implemented feature.
bump-version	Bump the service version and update the changelog.

The skills assume a Causa monorepo laid out under domains/<domain>/ (entities, events, api, firestore, spanner, service, doc). Design skills write their artifacts to domains/<domain>/work/<feature-slug>/.

Usage

CLI

Add the marketplace and install the plugin from within Claude Code:

/plugin marketplace add causa-io/agent-plugin
/plugin install skills@causa

Then invoke a skill, e.g. /build-feature, or just describe the task and let Claude pick the relevant skill.

Project .claude/settings.json

To enable the plugin for everyone working in a project, commit it to the project's .claude/settings.json:

{
  "extraKnownMarketplaces": {
    "causa": {
      "source": {
        "source": "github",
        "repo": "causa-io/agent-plugin"
      }
    }
  },
  "enabledPlugins": {
    "skills@causa": true
  }
}

Claude Code installs and enables the plugin automatically when the project is opened.

Updating

After the skills change upstream, refresh it to pull the latest:

/plugin marketplace update causa
