Compare MCP tool behavior between target and baseline versions using pre-built and custom stories with diff-based triage.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# BAT Story Evaluation You are the evaluator. Run the steps in order; each one uses the output of the step before it. ## Parse Arguments From `$ARGUMENTS`, extract: - `--baseline`: REQUIRED. Git tag/branch of the released version (e.g., `v6.6.1`). - `--agents`: Agent list (default: `gemini`). Comma-separated. - `--stories`: Force specific pre-built story IDs (e.g., `s01,s02`). Overrides triage selection. - `--all-stories`: Skip triage, run ALL pre-built stories. - `--keep-container`: Keep HA containers alive after run for manual inspection. - `--model`: Model for Claude agent (e.g., `haiku`, `sonnet`). If `$ARGUMENTS` is `--help` or missing `--baseline`, show usage and stop: ``` /bat-story-eval --baseline v6.6.1 /bat-story-eval --baseline v6.6.1 --agents gemini,claude /bat-story-eval --baseline v6.6.1 --stories s01,s02 /bat-story-eval --baseline v6.6.1 --all-stories --agents claude --model haiku ``` ## Step 0: Triage (Diff Analysis + Custom Story Design) ### 0a. Compute Diff ```bash cd "$(dirname "$(git rev-parse --path-format=absolute --git-common-dir)")/worktree/uat-stories" git diff <baseline>..HEAD -- src/ha_mcp/ --stat …

How to install
mdr add homeassistant-ai/ha-mcp/bat-story-eval@sha256:fb2c2f75f5cc2857The line at the top of this page pins the label git:20260926.4e60907, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
