-### Running .NET builds from an agent
-- Do not run `.NET` builds such as `dotnet run build`, `dotnet build`, or similar build commands from an agent. Codex agents can hit a known sandbox issue during `.NET` builds, typically surfacing as `CSSM_ModuleLoad()` or other sandbox-related failures.
-- Instead, ask the user to run the `.NET` build locally in their IDE and report the result back.
-- Recommend the canonical repo build flow for the user: open an IDE terminal in the repository and run `cd app/Build && dotnet run build`.
-- If the context fits better, it is also acceptable to ask the user to start the build using their IDE's built-in build action, as long as it is clear the build must be run locally by the user.
-- After asking for the build, wait for the user's feedback before diagnosing issues, making follow-up changes, or suggesting the next step.
-- Treat the user's build output, error messages, or success confirmation as the source of truth for further troubleshooting.

+### Running builds from an agent
+Agents must not start builds through their own shell: agent shells run sandboxed, and `.NET` builds
+hit a known sandbox issue there, typically surfacing as `CSSM_ModuleLoad()` or other sandbox-related
+failures (for reference: https://github.com/openai/codex/issues/4915). This applies to `dotnet run build`,
+`dotnet build`, `cargo build`, and similar commands.
+
+Instead, use the JetBrains IDE MCP servers. They execute in the IDE process, which runs outside the
+agent sandbox:
+
+- `rider` for the .NET solution at `app/MindWork AI Studio.sln`
+- `rustrover` for the Rust runtime at `runtime/`
+
+Pass the `rootFolder` parameter on every call, e.g. the absolute path of the `app` directory for Rider
+and of `runtime` for RustRover. It avoids ambiguous calls when several IDE windows are open.
+
+**Compile check of the .NET code:** start `mcp__rider__build_solution_start`, then poll
+`mcp__rider__build_solution_state` until its state is `Completed` and read `buildIsSuccess` plus the
+collected problems. `mcp__rider__get_project_problems` reports the current Problems View without
+triggering a new build.
+
+**Build script commands** such as the canonical build or the I18N collection run through the IDE
+terminal, because they are more than a solution build:
+
+```
+mcp__rider__execute_terminal_command  command: "cd app/Build && dotnet run build"
+mcp__rider__execute_terminal_command  command: "cd app/Build && dotnet run collect-i18n"
+```
+
+**Rust builds** work the same way through the matching `rustrover` tools.
+
+Notes:
+- The IDE may ask the user to confirm a terminal command. Wait for the result instead of retrying the
+  command in the agent shell.
+- When the IDE is not running or its MCP server is unavailable, fall back to asking the user to run
+  `cd app/Build && dotnet run build` locally, and wait for their feedback before diagnosing issues or
+  making follow-up changes.
+- Treat the build output, error messages, or success confirmation as the source of truth for further
+  troubleshooting, no matter whether it came from the MCP server or from the user.
