+title: Include Command Snippet in Session-Scoped Approval Label
+status: Not started  # one of: Not started, Started, Needs manual review, Done, Cancelled
+summary: When asking for session-scoped approval of a command, embed a truncated snippet of the actual command in the approval label for clarity.
+goal: |
+  Improve the session-scoped approval option label for commands by including a backtick-quoted snippet of the command itself (truncated to fit).  This makes it clear exactly which command (including parameters) will be auto-approved for the session.
+
+## Acceptance Criteria
+
+- The session-scoped approval label changes from generic text to include a snippet of the current command, e.g.:  
+  ```text
+  Yes, always allow running `cat x | foo --bar > out` for this session (a)
+  ```
+- If the command is too long, truncate the middle (e.g. `long-part…end-part`) to fit a configurable max length.
+- Implement the snippet templating in both Rust and JS UIs for consistency.
+- Add unit tests to verify snippet extraction, truncation logic, and label rendering for various command lengths.
+
+## Implementation
+
+**How it was implemented**  
+- In the command-review widget, capture the `commandForDisplay` string and apply a `truncateMiddle(maxLen)` helper.
+- Embed the truncated snippet into the session-scoped approval option label.
+- Make `maxSnippetLength` configurable via UI settings (default e.g. 30 characters).
+- Add tests covering snippet lengths under, equal to, and exceeding the max length, verifying correct ellipsis placement.
+
+## Notes
+
+- This clarifies what parameters will be auto-approved and avoids ambiguity when multiple similar commands occur.
