Plugin Inspector is a CLI tool and library for offline static and runtime analysis of OpenClaw plugins. It validates plugin structure, SDK imports, hook registrations, and manifest contracts without requiring a live OpenClaw host. The tool generates rich compatibility reports in JSON, Markdown, SARIF, and JUnit formats, integrates with CI pipelines (GitHub Actions, GitLab, CircleCI), and supports batch analysis across plugin corpora. Its architecture is modular: a core inspection engine (src/inspector.js) performs static analysis using AST parsing (acorn, eslint-scope) and regex-based detection; an optional runtime capture subsystem (src/capture-api.js, src/synthetic-probes.js) executes plugin entrypoints with a dynamically generated mock SDK (src/sdk-mock.js) to verify registration behavior and hook handling. The tool also includes a CI policy engine, workspace planning, platform probes, and profiling/diffing utilities. While tightly coupled to OpenClaw internals, the codebase demonstrates strong engineering practices with extensive test coverage, reusable components, and a well-defined public API surface.
