v0.94.0

Release Date: May 5, 2026

Highlights

New Tool: steroid_apply_patch

Atomic multi-file batch edits in a single MCP call. Input: {project_name, hunks: [{file_path, old_string, new_string}, ...]}. All hunks land inside one WriteCommandAction (“MCP Steroid: apply-patch (N hunks)”); per-file descending offset order; pre-flight rejects missing or non-unique old_string matches before touching any document; touched documents are saved before the call returns. Microshop-2 benchmark: 8 hunks across 8 files in ~66 ms, zero Edit fallbacks. Same engine is exposed in scripts as applyPatch { hunk(file, old, new); ... } on McpScriptContext.

New MCP Resources

• mcp-steroid://ide/apply-patch — multi-site literal-text edit recipe (DSL form).
• mcp-steroid://skill/execute-code-gradle — Gradle test execution: prefer IDE path (ProjectTaskManager.build), wait for ProjectDataImportListener.onFinalTasksFinished, surface failure cause from BuildView, toolchain-vendor + disabled-test-task patterns.
• mcp-steroid://skill/apply-patch-tool-description — tool-description article for the new tool.

Rewritten Resources

• mcp-steroid://lsp/rename — semantic rename via RenameProcessor instead of regex; correctly handles overrides, qualified references, annotation strings, dry-run.
• mcp-steroid://skill/execute-code-maven — pinned to the SM data-model approach (poll SMTestProxy instead of layering listeners), captures Run console via ProgramRunner.Callback, two-call test pattern (compile → run).
• mcp-steroid://skill/execute-code-tool-description — explicit threading-wrap rules surfaced on read-action errors; in-place edit recipe; apply-patch routing.
• mcp-steroid://skill/coding-with-intellij* — Observation.awaitConfiguration + smartReadAction for indexed reads (replaces unreliable waitForSmartMode).

DialogKiller Replaces ModalityStateMonitor

The 236-line ModalityStateMonitor is gone. DialogKiller runs as a periodic EDT poll, dismisses real DialogWrapper windows, and ignores coroutine progress entities and elevated ModalityState.any() blocks. Side effects: Maven and Gradle test runs no longer get cancelled mid-flight; SDK-lookup banners stop being flagged as modals. New per-call dialog_killer: true|false parameter on steroid_execute_code lets a script opt in/out.

Bug Fixes

• steroid_action_discovery wraps lookup in a read action and drops over-eager action-group expansion (which also removed an internal-API call to Utils.expandActionGroupSuspend) — #24.
• steroid_open_project calls TrustedPaths.setProjectPathTrusted(true) before opening, eliminating the trust modal on freshly cloned projects — #28, #30.
• steroid_execute_feedback now aggregates every validation error in one response instead of failing on the first.
• Tooltip text retrieval wrapped in a read action.
• ExceptionCaptureService survives JUL records with null LogRecord.parameters; the original IDE error is no longer masked.
• DialogWindowsLookup no longer flags elevated ModalityState.any() blocks as modal dialogs.

Output Hints from steroid_execute_code

• Script produced no user output → response appends a hint to add println(...).
• Build/Compile result errors=false, aborted=true → response appends REQUIRED ACTION: NEXT TOOL CALL must be mcp__mcp-steroid__steroid_fetch_resource with the matching Maven/Gradle resource URI.

VfsRefreshService

New project-level service. CodeEvalManager calls awaitRefresh() (suspending, 30 s cap) before kotlinc compiles a script, and scheduleAsyncRefresh() (fire-and-forget) in the finally after every steroid_execute_code and steroid_apply_patch call. PSI sees up-to-date files between back-to-back script calls without callers writing their own refresh boilerplate.

Plugin Verifier: Zero Internal-API Usages

Building on 0.93.0’s reduction (29 → 4): the action-group expansion path was the last avoidable internal-API call. The 0.94.0 binary reports 0 internal-API usages against both IntelliJ 2025.3 and 2026.1 under Plugin Verifier. Three experimental references remain — all of them public replacements that IntelliJ itself flags as experimental (IdeaPluginDescriptor.contentModules, suspending writeAction).

~10× Faster No-Change TDD Loop

External contributor Dmitry Protsenko (@NordCoderd) traced four orthogonal sources of cache invalidation in the build (#26): LocalDateTime.now() outside deployPlugin invocations (kept generateMetadata out-of-date), the orphaned Random.nextInt() seed in GenerateMetadataTask, missing inputs/outputs on npmBuild, and per-run If-Modified-Since round-trips for tessdata. Atomic OCR + Kotlin compiler downloads guard against corrupted-on-disk files. No-change ./gradlew :ij-plugin:test drops from ~28 s to ~3 s.

SDK-Lookup Modal Hardening

Three independent IntelliJ entry points fire an “Unknown SDK” / “Resolving SDKs…” modal on project open. The plugin now disables all three (-Dunknown.sdk=false, -Dunknown.sdk.auto=false, -Dunknown.sdk.modal.jps=false) and ships mcpListJdks / mcpAddJdk / mcpRegisterJdks driver helpers. Pre-registers bare/corretto-N/temurin-N aliases for every JDK on the agent before the IDE’s SdkLookup task can race in. JDK setup is skipped cleanly on non-Java IDEs (PyCharm, GoLand, WebStorm, Rider).

Other

• Ktor MCP idle timeout raised to 600 s (long Maven/Gradle test runs no longer drop the connection).
• New integration tests pinned to real flows: YouTrackDbMavenTest (split for 253 + 261), KeycloakMavenTest, RetrofitGradleTest → IntelliJPlatformGradleTest, OpenProjectTrustIntegrationTest, IntelliJThisLoggerLookupTest.
• Dropped unused SkillReference class and SteroidsMcpServerStartupActivity.
