-description = "Promote behavioral evals that have a 100% success rate over the last 7 nightly runs."
-prompt = """
-You are an expert at analyzing and promoting behavioral evaluations.
-
-1. **Investigate**:
-   - Use 'gh' cli to fetch the results from the most recent run from the main branch: https://github.com/google-gemini/gemini-cli/actions/workflows/evals-nightly.yml.
-   - DO NOT push any changes or start any runs. The rest of your evaluation will be local.
-   - Evals are in evals/ directory and are documented by evals/README.md.
-   - Identify tests that have passed 100% of the time for ALL enabled models across the past 7 runs in a row.
-   - NOTE: the results summary from the most recent run contains the last 7 runs test results. 100% means the test passed 3/3 times for that model and run.
-   - If a test meets this criteria, it is a candidate for promotion.
-
-2. **Promote**:
-   - For each candidate test, locate the test file in the evals/ directory.
-   - Promote the test according to the project's standard promotion process (e.g., moving it to a stable suite, updating its tags, or removing skip/flaky annotations). 
-   - Ensure you follow any guidelines in evals/README.md for stable tests.
-   - Your **final** change should be **minimal and targeted** to just promoting the test status.
-
-3. **Verify**:
-   - Run the promoted tests locally to validate that they still execute correctly. Be sure to run vitest in non-interactive mode.
-   - Check that the test is now part of the expected standard or stable test suites.
-
-4. **Report**:
-   - Provide a summary of the tests that were promoted.
-   - Include the success rate evidence (7/7 runs passed for all models) for each promoted test.
-   - If no tests met the criteria for promotion, clearly state that and summarize the closest candidates.

-Tests should score at least 66% with key models including Gemini 3.1 pro, Gemini
-3.0 pro, and Gemini 3 flash prior to check in and they must pass 100% of the
-time before they are promoted.
-
-## Test promotion process
-
-To maintain a stable and reliable CI, all new behavioral evaluations follow a
-mandatory deflaking process.
-
-1. **Incubation**: You must create all new tests with the `USUALLY_PASSES`
-   policy. This lets them be monitored in the nightly runs without blocking PRs.
-2. **Monitoring**: The test must complete at least 10 nightly runs across all
-   supported models.
-3. **Promotion**: Promotion to `ALWAYS_PASSES` happens exclusively through the
-   `/promote-behavioral-eval` slash command. This command verifies the 100%
-   success rate requirement is met across many runs before updating the test

 When investigating failures manually, you can also enable verbose agent logs by

-### Best practices
-
 It's highly recommended to manually review and/or ask the agent to iterate on
 any prompt changes, even if they pass all evals. The prompt should prefer
 positive traits ('do X') and resort to negative traits ('do not do X') only when
 unable to accomplish the goal with positive traits. Gemini is quite good at
 instrospecting on its prompt when asked the right questions.

-## Promoting evaluations
-
-Evaluations must be promoted from `USUALLY_PASSES` to `ALWAYS_PASSES`
-exclusively using the `/promote-behavioral-eval` slash command. Manual promotion
-is not allowed to ensure that the 100% success rate requirement is empirically
-met.
-
-### `/promote-behavioral-eval`
-
-This command automates the promotion of stable tests by:
-
-1.  **Investigating**: Analyzing the results of the last 7 nightly runs on the
-    `main` branch using the `gh` CLI.
-2.  **Criteria Check**: Identifying tests that have passed 100% of the time for
-    ALL enabled models across the entire 7-run history.
-3.  **Promotion**: Updating the test file's policy from `USUALLY_PASSES` to
-    `ALWAYS_PASSES`.
-4.  **Verification**: Running the promoted test locally to ensure correctness.
