Pluginize a Product DSL module set by hand-writing a wrapper plugin module next to its feature modules. Use when promoting modules out of an aggregate module set (e.g. `essential`, `ide.common`) into a bundled plugin so products can include or omit them through normal plugin wiring, when updating bundled plugin registration for such a wrapper, or when fixing tests whose plugin loading logs show a missing wrapper plugin for a former module set.

Run a Python file or snippet through the real third-party type checkers (ty, pyrefly, basedpyright, mypy, zuban) via uvx and collate their output into one Markdown report. Use when evaluating how a type should be inferred, debugging PyCharm code-insight / type-engine behaviour, or checking where the external checkers agree or disagree on a snippet.

Inspect the live runtime state of a currently running IntelliJ IDE through the MCP get_ide_diagnostics tool. Use only for IDE process diagnostics such as performance triage, UI freezes, high CPU, blocked threads, coroutine dumps, or thread dumps when the user wants current evidence from the running IDE, not for general debugging, generic issue diagnosis, build/test failures, logs, or MCP server self-diagnostics.

Prepare a Jewel pull request for the intellij-community repository. Validates commit message format, runs local CI checks (detekt, tests, API dumps, Metalava), ensures the branch is squashed to a single commit, checks for visual change screenshots, drafts release notes, and suggests a PR title and description. Optionally creates the PR via gh. Use when the user is ready to submit or review a Jewel contribution.

Assist with preparing a Jewel release. Covers version bumps, API version code generation, running checks (Gradle, detekt, Metalava), extracting and writing release notes, cherry-picking to release branches, comparing branches for missing commits, validating Maven artifacts, and tagging. Use when the user is preparing a new Jewel version release.

Interact with the JetBrains YouTrack instance (youtrack.jetbrains.com) via REST API. Create, read, update, and search issues and drafts; manage comments, tags, and issue links; log work items; inspect custom field schemas; list saved queries; look up users and groups. Use when the user asks about YouTrack issues, wants to file bugs, update tickets, add comments, manage tags or links, track time, or search for issues. Requires YOUTRACK_TOKEN environment variable.

Guide for writing UI tests using IDE Starter and UI Driver frameworks. Use when creating or modifying UI tests or when user ask to implement test case from testops.

Use this skill whenever the user asks to commit changes, write or fix a commit message, amend or rename a commit, or do a workflow that includes committing in the IntelliJ repository. This is a thin repo-specific overlay: use IntelliJ commit format, write full commit messages by default, and keep requested suffixes such as IJ-MR trailers in a final separate paragraph.
