| agent.type | string | |
| agent.version | number | |
| archived_at | null | string | A timestamp in RFC 3339 format |
| budget | null | object | A hard spend ceiling. The session stops issuing new model requests once the tracked list cost reaches `max_list_cost`. |
| budget.max_list_cost | object | A monetary amount in a specific currency. |
| budget.type | string | |
| created_at | string | A timestamp in RFC 3339 format |
| environment_id | string | |
| metadata | object | |
| outcome_evaluations | array<object> | Per-outcome evaluation state. One entry per `define_outcome` event sent to the session. |
| outcome_evaluations[].completed_at | null | string | A timestamp in RFC 3339 format |
| outcome_evaluations[].description | string | What the agent should produce. |
| outcome_evaluations[].explanation | null | string | Grader's verdict text from the most recent evaluation. For `satisfied`, explains why criteria are met; for `needs_revision` (intermediate), what's missing; for `failed`, why unrecoverable. |
| outcome_evaluations[].iteration | number | 0-indexed revision cycle the outcome is currently on. |
| outcome_evaluations[].outcome_id | string | Server-generated outc_ ID for this outcome. |
| outcome_evaluations[].result | string | Current evaluation state. `pending` before the agent begins work; `running` while producing or revising; `evaluating` while the grader scores; `satisfied`/`max_iterations_reached`/`failed`/`interrupted` are terminal. |
| outcome_evaluations[].type | string | |
| resources | array<object> | |
| resources[].id | string | |
| resources[].created_at | string | A timestamp in RFC 3339 format |
| resources[].mount_path | string | null | string | Filesystem path where the store is mounted in the session container, e.g. /mnt/memory/user-preferences. Derived from the store's name. Output-only. |

| resources[].memory_store_id | string | The memory store ID (memstore_...). Must belong to the caller's organization and workspace. |
| resources[].access | null | string | Access mode for an attached memory store. |
| resources[].description | string | Description of the memory store, snapshotted at attach time. Rendered into the agent's system prompt. Empty string when the store has no description. |
| resources[].instructions | null | string | Per-attachment guidance for the agent on how to use this store. Rendered into the memory section of the system prompt. Max 4096 chars. |
| resources[].name | null | string | Display name of the memory store, snapshotted at attach time. Later edits to the store's name do not propagate to this resource. |
| stats | object | Timing statistics for a session. |
| stats.active_seconds | number | Cumulative time in seconds the session spent in `running` status. Excludes idle time. |
| stats.duration_seconds | number | Elapsed time since session creation in seconds. For terminated sessions, frozen at the final update. |
| status | string | SessionStatus enum - `rescheduling` - Transient error occurred, retrying automatically. - `running` - Agent is actively executing. - `idle` - Agent is waiting for input, including user messages or tool confirmations. Sessions start in idle. - `terminated` - Session has ended, either due to an error or completion. |

| updated_at | string | A timestamp in RFC 3339 format |
| usage | object | Cumulative token usage for a session across all turns. |
| usage.active_seconds | number | Cumulative time in seconds during which the session had at least one thread in running status. Overlapping activity from concurrent threads is counted once, unlike `stats.active_seconds`, which sums each thread's own active time. This is the duration the session's runtime cost is priced on. |
| usage.cache_creation | object | Prompt-cache creation token usage broken down by cache lifetime. |
