| Field | Description |
|---|---|
| `ls_agent_kind` | High-level kind of agent, for example `"coding-agent"`. |
| `ls_agent_type` | The run's type within the agent. Should be one of `"root"`, `"subagent"`, `"middleware"`, or `"compaction"`. |
| `ls_agent_purpose` | High-level purpose of the agent, for example `"coding"`. |
| `ls_integration` | Identifier of the integration emitting the run (see [Supported integrations](#supported-integrations)). |
| `ls_agent_runtime` | Human-readable runtime name, for example `"Claude Code 1.0.28"`. |
| `thread_id` | Stable identifier for the conversation thread. Used to group related runs in LangSmith's Threads view. |
