Authorizations

Authorization

string

header

required

OAuth 2.0 / OIDC bearer token.

Tenant-Name

string

header

required

The tenant the request operates within.

Path Parameters

agentId

string<agent-id>

required

Agent identifier (prefixed UUIDv7). Agent identifier. Accepts agt.<uuidv7> or a bare UUIDv7 on input; always returned prefixed.

Pattern: ^(agt\.)?[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$

Example:

"agt.0192f4c8-2c5a-7b3e-9f1a-3c8d6e2b7a40"

Body

application/merge-patch+json

The fields to change, as a JSON Merge Patch (RFC 7386).

JSON Merge Patch body. Omitted fields are unchanged; null clears a field only where the field is nullable (see each property), so non-nullable fields such as maxLoops reject null; connectors is replaced wholesale. Note: the server currently honors only name, description, systemPrompt, model, maxLoops, and connectors. visibility, lifecycle, and labels are accepted but not yet persisted.

name

string

New agent name.

Required string length: 1 - 128

Example:

"coder-v2"

description

string | null

New description; null clears it.

Maximum string length: 4096

Example:

"Returns SNOMED CT codes for a clinical encounter."

systemPrompt

string | null

New system prompt; null clears it.

Example:

"Respond with only the SNOMED CT code."

model

string | null

New model identifier; null falls back to the tenant default.

Example:

"corti-default"

maxLoops

integer<int32>

New cap on the orchestrator's ReAct loop iterations per run. Omitted leaves the current value unchanged; there is no null-reset — send 10 to restore the default.

Required range: 1 <= x <= 100

Example:

10

visibility

enum<string>

private — creator / service principal only.
unlisted — usable by ID, hidden from list results.
public — listed tenant-wide.

Available options:

private,

unlisted,

public

Example:

"private"

lifecycle

enum<string>

default:ephemeral

ephemeral — short-lived; expired automatically.
persistent — retained until explicitly deleted.

Available options:

ephemeral,

persistent

connectors

object[] | null

Replacement connector list; null clears connectors.

Same envelope as Connector but without the server-generated id.

Option 1
Option 2
Option 3
Option 4
Option 5

Show child attributes

Example:

[
  {
    "type": "registry",
    "name": "pubmed-expert"
  }
]

labels

object | null

Replacement labels; null clears labels.

Show child attributes

Example:

{ "team": "coding", "env": "prod" }

Response

The updated agent.

A configured agent — its metadata, model, and attached connectors.

string<agent-id>

required

Agent identifier. Accepts agt.<uuidv7> or a bare UUIDv7 on input; always returned prefixed.

Pattern: ^(agt\.)?[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$

Example:

"agt.0192f4c8-2c5a-7b3e-9f1a-3c8d6e2b7a40"

name

string

required

Human-readable, unique-per-tenant agent name.

Required string length: 1 - 128

maxLoops

integer<int32>

required

Effective cap on the orchestrator's ReAct loop iterations per run. Always present: agents created without maxLoops report the server default (10).

Required range: 1 <= x <= 100

Example:

10

visibility

enum<string>

required

private — creator / service principal only.
unlisted — usable by ID, hidden from list results.
public — listed tenant-wide.

Available options:

private,

unlisted,

public

Example:

"private"

lifecycle

enum<string>

default:ephemeral

required

ephemeral — short-lived; expired automatically.
persistent — retained until explicitly deleted.

Available options:

ephemeral,

persistent

connectors

object[]

required

Connectors attached to the agent, discriminated by type.

A connector attached to an agent, discriminated by type.

Option 1
Option 2
Option 3
Option 4
Option 5

Show child attributes

createdAt

string<date-time>

required

read-only

When the agent was created.

updatedAt

string<date-time>

required

read-only

When the agent was last updated.

createdBy

string<user-id>

required

read-only

Principal (user or service principal) that created the agent.

Pattern: ^(usr\.)?[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$

Example:

"usr.0192f4c8-8bc0-7194-8570-92e3ce81d0a6"

description

string | null

Free-form agent description shown to users and in tooling.

Maximum string length: 4096

systemPrompt

string | null

System prompt prepended to every invocation.

model

string | null

Model identifier. Tenant default if omitted or null. Open question — in the current implementation a model is configured per expert, not per agent (Expert.modelName), and an Agent has no model field at all. The desired end state is that there is no distinction between an expert and an agent, so model lives uniformly on this resource. Until that convergence lands, the precedence of an agent-level model over a connector/expert-level override is undecided and MUST be resolved before this field ships.

Example:

"corti-default"

labels

object

Free-form string → string metadata for filtering and organisation. Not used for routing or auth.

Show child attributes

Example:

{ "team": "coding", "env": "prod" }

expiresAt

string<date-time> | null

read-only

When the agent expires; null means it does not expire. Ephemeral agents get a 24h expiry at creation time; persistent agents never expire.
