Parameters

Path Parameters

conversation_id

required

string

/^con_[A-Za-z0-9]+$/

Internal conversation ID.

Responses

200

The conversation.

application/json

An agent conversation owned by a user within a tenant. Snapshots its resolution context at creation and carries live runtime state.

object

object

required

string

Allowed value: conversation

required

string

/^con_[A-Za-z0-9]+$/

tenant_id

required

string

/^tnt_[A-Za-z0-9]+$/

user_id

required

string

/^usr_[A-Za-z0-9]+$/

title

required

Display title; auto-derivable from the first message.

string | null

<= 255 characters

status

required

Archived conversations keep readable history but reject message writes with 409 conversation-archived.

string

Allowed values: active archived

repository_id

required

Conversation-level repository override in the cascade.

string | null

/^rep_[A-Za-z0-9]+$/

context

required

Resolution snapshot taken at conversation creation (user → role → repository → skills) — makes history self-explaining even after roles or repositories change.

object

role_id

required

The role the conversation was resolved under.

string

/^rol_[A-Za-z0-9]+$/

repository_id

required

The effective repository at creation.

string

/^rep_[A-Za-z0-9]+$/

skill_ids

required

The effective skills at creation.

Array<string>

selected_skill_ids

required

Optional narrowing within context.skill_ids; null means no narrowing.

Array<string> | null

runtime

required

Runtime placement state of a conversation. agent_type selects the agent runtime behind the platform’s runtime abstraction — each type runs in its own isolated sandbox.

object

agent_type

required

Agent runtime — open enum so new runtimes are non-breaking. Known values: claude-agent-sdk, codex, deepagent. Defaults from tenant settings. Immutable after creation.

string

mode

required

pooled — each message claims a warm-pool sandbox; sticky — a dedicated sandbox is leased for sticky_ttl_seconds (refreshed per message).

string

Allowed values: sticky pooled

sticky_ttl_seconds

required

Lease TTL; null for pooled conversations.

integer | null

sandbox_state

required

warm — no dedicated sandbox held (pooled, or sticky before first message); active — sticky lease held; expired — sticky lease lapsed (next message re-acquires, subject to capacity).

string

Allowed values: warm active expired

expires_at

required

Sticky lease expiry; null for pooled conversations.

string | null format: date-time

filler

required

One of:

object
null

Filler-agent enablement. Cascade: tenant settings → conversation → message; most specific wins. When enabled, filler output arrives as content_delta events flagged data.filler: true.

object

enabled

required

Whether the low-latency filler agent runs for this scope.

boolean

storage

required

S3-style storage bucket attached to a user or conversation. Platform-assigned automatically at creation; host-owned buckets can be linked via update (provider: "external").

object

provider

required

platform — bucket provisioned and owned by the deployment; external — host-linked BYO bucket.

string

Allowed values: platform external

bucket_uri

required

S3-style URI of the bucket root (e.g. s3://bucket/prefix).

string

message_count

required

Persisted message count (all roles).

integer

last_message_at

required

Timestamp of the newest message; null when empty.

string | null format: date-time

metadata

required

Free-form string key–value map for host/adapter bookkeeping (e.g. a host-side reference ID). Max 50 keys; values max 500 chars. Replaced wholesale when provided in updates.

object

<= 50 properties

key

additional properties

string

<= 500 characters

created_at

required

RFC 3339 / ISO 8601 timestamp, UTC.

string format: date-time

updated_at
