CAPABILITY PROFILE

What the CustomGPT.ai integration exposes

The CustomGPT.ai Agent App exposes 7 provider-backed actions for ai and productivity work. Its current contract lets an authorized agent get details and current status for a customgpt agent, create a customgpt conversation for an agent and return its session id, and list customgpt agents in the authenticated account with optional pagination. These operations are called through Working Machines as typed capabilities rather than through browser navigation or copied UI steps.

A connection uses API key. Before execution, the agent can inspect the selected action, its required fields, declared scopes, and expected output contract. Provider credentials remain inside the Working Machines runtime; the calling agent receives the capability and its structured result, not the underlying secret.

For reliable operation, start with the narrowest action that satisfies the task, resolve stable provider identifiers before changing state, and validate the returned object or status after execution. Availability still depends on the connected CustomGPT.ai account, granted provider permissions, workspace policy, region, plan, and upstream API behavior.

PROVIDER-SPECIFIC WORKFLOWS

Jobs this Agent App can support

Inspect Get Agent

Get details and current status for a CustomGPT agent. Use this as a bounded discovery step, retain the returned identifier, and avoid expanding the read beyond the task's stated scope.

get_agent

Control Create Conversation

Create a CustomGPT conversation for an agent and return its session ID. Resolve the target first, present material changes for confirmation, and make retries idempotent where the provider supports it.

create_conversation

Verify with List Agents

List CustomGPT agents in the authenticated account with optional pagination. Compare the returned provider state with the intended outcome and preserve stable IDs or canonical links in the run record.

list_agents

SAFETY BOUNDARY

Operate CustomGPT.ai with explicit limits

  • Authorize CustomGPT.ai with API key and grant only the provider access required by the selected actions.
  • 2 actions are change-capable by name. Confirm the target identity and material parameters before allowing a write.
  • Do not infer permission from catalog visibility. Workspace policy, connection identity, and upstream authorization still govern execution.
  • No provider scope string is declared on the sampled actions. Verify the connected account's actual permissions in CustomGPT.ai rather than assuming unrestricted access.
  • After a call, inspect the structured result and execution record before reporting that the CustomGPT.ai task completed successfully.

CONNECTION MODEL

API key

CustomGPT API key sent as an Authorization Bearer token. Create it in the CustomGPT profile API tab: https://app.customgpt.ai/profile#api.

Working Machines stores provider credentials behind the execution boundary. An agent can use an authorized connection identity, but catalog discovery alone does not reveal OAuth tokens, API keys, or provider secrets.
