mps-console
Use when running or generating MPS Console code, or when writing `jetbrains.mps.lang.smodel.query` queries anywhere in MPS (intentions, behavior, actions, generator queries, plain BaseLanguage). Covers the console command languages (`jetbrains.mps.console.base` / `ideCommands` / `internalCommands` / `scripts`): `BLCommand` / `BLExpression`, the `#print*` / `#show` result printers, IDE commands (`#make` / `#clean` / `#removeGenSources` / `#reloadClasses` / `#stat` / `#showGenPlan` / `#showBrokenRefs`), `#exec` / `forEach` / `refactor` scripts. Covers the smodel query language: `#nodes` / `#references` / `#models` / `#modules` / `#instances` / `#usages`, the `with`-statement scope wrapper, scopes (`project` / `editable` / `global` / `visible` / `modules` / `models` / `custom`) and query parameters (`scope` / `exact` / `r/o+`). Also how to insert, read, recall, and run console commands with `mps_mcp_insert_console_command_from_json`, `mps_mcp_get_current_editor_root_node(source="console")`, `mps_mcp_get_console_history`, `mps_mcp_recall_console_command`, and `mps_mcp_run_console_command`.
Security
1 critical severity finding. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
The documentation exposes MCP APIs that allow an agent to programmatically insert, recall, read, and execute console commands (including headless bulk mutations via forEach) and to read console history/responses — capabilities that enable remote code execution and data exfiltration if a malicious or compromised agent uses them.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
W011: Third-party content exposure detected (indirect prompt injection risk).
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
The required workflow reads outsider-authored free text from the user/agent-populated MPS Console input via `mps_mcp_run_console_command`, which executes whatever command is currently in the input (including agent-inserted code from `mps_mcp_insert_console_command_from_json`).
