plugin-model-analyzer

name	plugin-model-analyzer
description	Query IntelliJ Product DSL modules, products, plugin graphs, loading, and packaging.

Plugin Model Analyzer

Use the Product DSL analyzer directly through Bazel. Do not call the retired PluginModelAnalyzer MCP server.

Command Shape

Run from the repository root:

bazel run --ui_event_filters=-info --noshow_progress //platform/buildScripts:plugin-model-tool -- --json='<request-json>'

The output is JSON with a timestamp plus one result property named after the requested filter.

Prefer small, typed JSON requests. Avoid unfiltered --json: it emits the full model and is usually too large for agent context. Use JSON fields, not extra CLI flags, to describe the query. Treat the single top-level result property as the answer.

Transport options:

• Short request: --json='{"filter":"summary","limit":5}'
• Stdin request: --json=-
• File request: --json=@/private/tmp/plugin-model-query.json

Fast Recipes

Where is a module included?

{"filter":"moduleInfo","module":"<module>","limit":50}
{"filter":"modulePaths","module":"<module>"}

What depends on what, and why?

{"filter":"moduleDependencies","module":"<module>","includeTransitive":false,"includeTestDependencies":false}
{"filter":"dependencyPath","fromModule":"<from>","toModule":"<to>","includeTestDependencies":true,"includeScopes":true}

Who owns a module?

{"filter":"moduleOwners","module":"<module>","includeTestSources":true}

Which products or module sets use something?

{"filter":"moduleInfo","module":"<module>","limit":50}
{"filter":"productQuery","usesModuleSet":"<module-set>","limit":50}
{"filter":"productUsage","moduleSet":"<module-set>"}

Can a module stop being embedded?

{"filter":"moduleInfo","module":"<module>","limit":50}
{"filter":"moduleLoading","loading":"EMBEDDED","details":true,"limit":200}
{"filter":"validation","check":"embedded_dependency_closure","module":"<module>","pluginSourceOnly":true}

For the loading query, inspect moduleLoading.result.entries.items for the target module; moduleLoading filters by loading rule, not by module name. The embedded closure check answers whether an embedded source module has dependencies that are not also supplied by embedded sources in affected products.

Did a Product DSL edit introduce placement or loading problems?

{"filter":"validation","check":"community_products"}
{"filter":"validation","check":"module_set_locations"}
{"filter":"validation","check":"loading_inconsistencies"}
{"filter":"validation","check":"embedded_dependency_closure","pluginSourceOnly":true}

Which module set should contain these modules?

{"filter":"suggestModuleSetsForModules","modules":["<module1>","<module2>"],"limit":20}

Reading Output

• Compact list fields use count, items, and truncated; increase limit or set details:true only when needed.
• Some focused filters return an error field in JSON for missing selectors or unknown names; a successful process exit does not always mean the query matched.
• For direct embeddedDependencyClosure, use value for the product selector. The validation wrapper accepts product or value.
• location values are COMMUNITY or ULTIMATE. loading values are EMBEDDED, REQUIRED, OPTIONAL, ON_DEMAND, or UNSPECIFIED.

Request Fields

Use only fields relevant to the filter. Omit false, null, and default values unless they are semantically important.
