Write and maintain Micronaut Framework module guides for micronaut-projects repositories. Use when users ask to add or update AsciiDoc guide sections, edit guide toc.yml, apply Micronaut docs macros, or fix docs build/publishing tasks.

Implement and review Java code changes for Micronaut framework repositories using maintainer standards, including JSpecify null-safety conventions. Use when users ask to add or refactor Java code, fix framework bugs, evolve internal APIs, or prepare committer-ready changes with tests and verification.

Create or update standalone Micronaut Guides in micronaut-projects/micronaut-guides, including topic discovery, guide authoring, validation, PDF export, and pull request handoff. Use for requests to create a Micronaut Guide, add a guide to micronaut-guides, author a tutorial for a Micronaut module, or prepare a guide PR with PDF.

Add, integrate, or review Micronaut Sourcegen usage in modules that generate Java source, Kotlin source, Groovy-compatible source, or bytecode from ObjectDef, TypeDef, MethodDef, ExpressionDef, StatementDef, and SourceGenerator APIs.

Refactor oversized agent instruction files into a progressive-disclosure structure. Use when users ask to split AGENTS.md/CLAUDE.md/COPILOT.md, reduce instruction bloat, or organize guidance into linked topic files.

Execute Gradle maintainer operations for Micronaut repositories using micronaut-build internals and modern Gradle best practices. Use when users ask to diagnose build failures, maintain BOM/version catalogs, manage publishing/signing, enforce binary compatibility, or debug micronaut-build plugin behavior.

Create new Agent Skills or improve existing ones in an agent-agnostic way. Use when users ask to build, refactor, validate, or package skills compatible with the Agent Skills specification and the skills CLI ecosystem.
