Python maintenance dispatcher — fixes ruff / semgrep / Code Scanning / SonarCloud findings autonomously via per-tool agents in parallel worktrees, auto-bumps deps (patch + minor + major) with test-based verification. Favors autonomy over speed: expect tens-of-thousands of tokens per run.

🔌

development-java🔌Plugin

Java/Gradle maintenance plugin — full-maintenance tier mirroring development-python. Dispatches per-tool agents (Spotless, SonarCloud, CodeQL/Scorecard, semgrep, Dependabot/Snyk PRs, Gradle major upgrades) in worktrees, with a JaCoCo coverage pre-flight; ships the java-approver reviewer + /development-java:approve. JDK runtime upgrades land in a later slice (#308).

🔌

development-spring🔌Plugin

Spring framework TOPIC plugin — composes alongside development-java for Java + Spring Boot 4+ repos (baseline Spring Framework 7 / Jakarta EE 11; older Boot lines out of scope). Audits Spring configuration via spring-config-advisor; reuses java-ci-fixer for CI. Incremental: config audit in v0.1; a Spring Boot version-upgrade agent, bootBuildImage, and the contract-first API drift gate land in later slices (#296).

🔌

development-claude-plugin🔌Plugin

Plugin family for projects that ARE Claude Code plugins. Ships a test harness (/development-claude-plugin:test) and a maintenance dispatcher that validates plugin conventions and composes alongside the language plugin. Validators: version sync, SKILL.md/agent frontmatter, orphaned skill/agent references, directory layout, and shell-script quality (shellcheck / zsh -n).
