## Evidence gaps
> RepoPilot has not run the setup commands or tests.
> Files marked “likely” are guessed from their names.
> Some entry points named in the manifest are build output or are missing from the file list, so their source is not shown.
> Could not capture package-lock.json: source unavailable or larger than the capture limit. Open its source link to check setup.
> The intended package manager and version are not established by captured evidence.
> Root development commands were not established. Check the root manifest and contributor guide.
> Setup has not been executed. Environment variables, external services and command order may require additional source documentation.
## Further evidence
This brief can be used without a connection. If RepoPilot is connected, its hosted MCP endpoint is https://repopilot.app/api/mcp.
- Concise brief: analyze_repo {"repo":"ChromeDevTools/chrome-devtools-mcp"}
- Full reference: get_artifact {"repo":"ChromeDevTools/chrome-devtools-mcp"}
- For a concrete task, call plan_repo_task with this repository, the task, and your actual checkout SHA when known. Compare returned analyzed_sha and evidence_gaps before relying on its file guidance.
- Follow the tool result's next_actions for more evidence. A missing result or unknown revision remains unverified.
Before you rely on it
- RepoPilot has not run the setup commands or tests.
Optional: connect RepoPilot over MCP so your agent can look things up itself.
