Show HN: A Claude Code plugin for build agent (dogfodding it now) (github.com)

Open-source plugin announced for Claude Code that integrates with the ConnectOnion framework to speed up and standardize agent development by offering machine-driven, persona-styled code reviews and scaffolding. Developers can install it from the ConnectOnion marketplace (plugin marketplace add openonion/connectonion-claude-plugin; plugin install connectonion) and interact via slash commands like /aaron-review-my-code, /linus-review-my-code, /aaron-build-my-agent, /generate-code-map-headers and /design-refine. Aaron (the framework creator) provides constructive, educative reviews and can scaffold runnable agents with proper system prompts, type hints, pattern selection (functions vs class instances) and usage docs; Linus hunts over‑engineering and code smells. The plugin also generates code-map headers that build import dependency graphs, detect circular deps, document data flow, list side effects and tests, and output prioritized TODOs. This matters for AI/ML engineering teams because it dogfoods framework best practices and reduces common agent pitfalls—hallucinations are minimized by grounding recommendations in ConnectOnion docs, and reviews enforce specifics important to LLM-driven tooling (typed tool signatures, markdown system prompts, simple-first patterns, maintainability). Technical implications include automated enforcement of type-hinted tool schemas, pattern-aligned Agent() initialization, dependency-aware documentation for safe refactors, and quick scaffolding for stateful or stateless agents — all under an Apache-2.0 repo with GitHub/Discord links for issue reporting and community support.
