    - **Only if the user explicitly requests a comparison or benchmark**, also spawn a **Baseline** subagent. See `resources/baseline_execution_prompt.md` for the template.
    Instruct the subagent(s) to return their `git diff` and verification outputs (`dart format`, `dart analyze`, `dart test`) without committing.
    **CRITICAL**: You must explicitly warn the subagent(s) to confine all file edits strictly to their current working directory and avoid using absolute paths to modify the parent workspace.
+   **WORKSPACE LIMITATION WARNING**: If the user has multiple active workspaces mounted, the `Workspace: branch` feature will fail. In this situation, you MUST warn the user that running concurrent evaluations in `Workspace: inherit` mode will cause git state bleed and cross-eval pollution (e.g., changes made by a failure scenario will be visible to a success scenario running simultaneously in the same shared directory). Instruct the user to fix this by closing all workspaces except the primary package workspace, and then re-run the evaluations. Do NOT silently fallback to `Workspace: inherit` for concurrent tasks.
 5. **Grade**: Parse the combined rubric (resolving `repo_criteria` + `evals.json` expectations). Use the grading instructions in `resources/agent_judge_prompt.md`. When an expectation fails, you MUST explicitly list both the expectation and what was actually found that caused the failure.
 6. **Artifact**: Grade the outputs and generate a Markdown artifact (e.g., `<skill>_eval_results.md`) containing the metadata, pass/fail rationale, and raw diffs/stdout.
