-The [`ambient-action`](https://github.com/ambient-code/ambient-action) GitHub Action (v0.0.2) creates Ambient Code Platform sessions directly from GitHub workflows. Use it to automate bug fixes on new issues, run code analysis on pull requests, or trigger any agent workflow from CI/CD.
+The [`ambient-action`](https://github.com/ambient-code/ambient-action) GitHub Action creates Ambient Code Platform sessions directly from GitHub workflows. Use it to automate bug fixes on new issues, run code analysis on pull requests, or trigger any agent workflow from CI/CD.
 
 ## Modes
 
 - **Fire-and-forget** -- Create a session and move on. The workflow does not wait for the session to finish.
 - **Wait-for-completion** -- Create a session and poll until it completes (or times out). Useful when subsequent steps depend on the agent's output.
+- **Send to existing session** -- Send a message to a running session instead of creating a new one (set `session-name`).
 
 ## Inputs

+| `api-token` | Yes | -- | Bot user bearer token for authentication (store as a GitHub secret) |
 | `project` | Yes | -- | Target workspace/project name |
-| `prompt` | Yes | -- | Task prompt for the agent |
+| `prompt` | Yes | -- | Initial prompt for the session, or message to send to an existing session |
+| `session-name` | No | -- | Existing session name to send a message to (skips session creation) |

 | `environment-variables` | No | -- | JSON object of environment variables to inject into the runner |
 | `workflow` | No | -- | JSON workflow object (e.g., `{"gitUrl":"https://...","branch":"main","path":"workflows/my-wf"}`) |
 | `model` | No | -- | Model override (e.g., `claude-sonnet-4-20250514`) |
+| `timeout` | No | `0` | Session inactivity timeout in seconds -- auto-stops after this duration of inactivity (`0` means no timeout) |
+| `stop-on-run-finished` | No | `false` | Stop the session automatically when the agent finishes its run |
 | `wait` | No | `false` | Wait for session completion |
