 ## [Unreleased]
 
+### Fixed

+- **`session tell` missing `--format` flag and JSON envelope output** (#10466): Added
+  `--format`/`-f` option to `agents session tell` so machine-readable output (JSON,
+  YAML, plain) is available alongside the existing Rich console output. When a
+  non-rich format is requested the response is wrapped in the spec-required JSON
+  envelope containing session metadata, the assistant response, and usage statistics.

 ### Changed
