Ask the application user concise structured questions when missing information blocks a safe AI4J agent action.

Fixture skill for extension validation tests.

CLI skill

Coding extension skill

Use this skill when helping users build applications with AI4J in their own Java or Spring Boot projects, including first chat, streaming, tool/function calls, MCP, RAG, memory, Agent runtime, Coding Agent CLI embedding, FlowGram integration, provider configuration, dependency selection, and troubleshooting. It guides beginner-friendly app scaffolding, secure environment-variable configuration, smallest useful AI4J module selection, runnable examples, and verification steps. For AI4J repository maintenance, follow the repository AGENTS.md and coding-agent-harness files instead of this user-facing app builder skill.

Use Keel as the local-first workflow ledger and candidate-change boundary for coding-agent work. Trigger in Keel-enabled repositories, when asked to self-dogfood Keel, when managing long Codex/Claude/OpenCode sessions, when recording checkpoints, notes, evidence, review, verify, handoff, or when deciding the next safe command with `keel`.

Collect, evaluate, and prepare icon assets for draw.io diagrams, academic paper figures, PPT slides, and frontend design. Use when the user needs SVG or transparent PNG icons, wants to extract site icons or logos, compare candidate assets, convert formats, or prepare icons for publication-quality or design-quality output.

Provide SysML v2 guidance, examples, and official-first validation for .sysml/.kerml work. Use when Codex needs to generate SysML v2 syntax, review or explain SysML v2 project code, validate single files, validate multi-file imports, validate whole directories, run official Pilot-based checks, or apply bundled SysML v2 standard library context during analysis.
