 ## Output Handling
 
 - Parse each NDJSON line independently.
 - Collect `finding` events and group them by severity.
 - Ignore `status` events in the user-facing summary.
-- If an `error` event is returned, report the failure instead of inventing a manual review.
-- Treat a running CodeRabbit review as healthy for up to 10 minutes even if output is quiet.
-- Do not emit intermediary waiting or polling messages during that 10-minute window.
-- Only report timeout or failure after the full 10-minute wait budget is exhausted.
+- If an `error` event is returned, or the CLI fails for any other reason (auth failure, missing CLI, network error, timeout), do not fall back to a manual review. Report the exact failure and tell the user how to resolve it (e.g. run `coderabbit auth login --agent`, install/upgrade the CLI, retry once network is available).
+- Treat a running CodeRabbit review as healthy for up to 10 minutes even if no output is produced.

 ## Result Format
 
 - Start with a brief summary of the changes in the diff.
-- On a new line, state how many findings CodeRabbit found.
-- Present findings ordered by severity: critical, major, minor.
-- Format the severity/category label with a space between the emoji and the text, for example `❗ Critical`, `⚠️ Major`, and `ℹ️ Minor`.
-- Include file path, impact, and the concrete fix direction.
-- If there are no findings, say `CodeRabbit found 0 findings.` and do not invent issues.
+- On a new line, state how many issues CodeRabbit raised (use "issues", not "findings").
