A sample command that can be used to demonstrate this is: |
Add an agent-driven verdict mode, the natural-language equivalent of --command (like `git bisect run`). `--prompt "<instruction>"` shells out to the `claude` CLI in headless mode, pointed at the @mozilla/firefox-devtools-mcp server via a generated --mcp-config, to inspect each build and decide good/bad. The MCP launches the build itself, so AgentTestRunner installs the build to obtain the binary path (passed via --firefox-path) without starting it. Verdicts are parsed as GOOD/BAD from the agent output. Gating: the Firefox DevTools MCP supports Firefox 100+, so ranges that predate it are rejected. This happens both up front (resolved good/bad range in cli.validate) and per build (mozversion application_version), configurable via --prompt-min-version (default 100). A pre-run check (Application.check_prerequisites) fails fast before bisecting if `claude`/`npx` are missing or if the instruction is not usable for a good/bad determination. --prompt is mutually exclusive with --command and --launch. Adds --prompt-headless and --prompt-model. New UnsupportedVersionError.
