 ## Unreleased
 
+- Fixed `agents session list`, `agents session create`, and other session
+  subcommands raising `AttributeError: 'DynamicContainer' object has no
+  attribute 'db'` after `agents init`.  Root cause: `_get_session_service()`
+  called `container.db()` but no `db` provider existed.  Added a
+  `session_service` DI provider in `container.py` that builds the engine,
+  sessionmaker, and auto-committing repositories.  Rewrote
+  `_get_session_service()` to resolve via the container with module-level
+  caching.  Added `auto_commit` parameter to `SessionRepository` and
+  `SessionMessageRepository` to prevent resource leaks in CLI context while
+  preserving Unit-of-Work semantics.  Unified error handling across all 7
+  session subcommands.  Includes Behave BDD regression scenarios, Robot
+  Framework integration smoke tests, and structlog isolation for parallel
+  test execution.  (#554, #570, #680)
 - Added dedicated E2E test infrastructure: new `nox -s e2e_tests` session
   running Robot Framework with `--include E2E` tag filter against `robot/e2e/`
   directory, dedicated CI job with real LLM API key secrets, graceful skip
