Give agents a deliberately limited set of operations

Start with operations that already make sense

An agent does not remove the need for a well-defined integration. It adds a caller that needs deliberate authorization, bounded inputs, and an execution budget. Invokation’s intended AI extension would expose selected application-owned operations as tools while retaining the same customer profiles and inspection model.

The platform should be useful to a conventional application without any model. Named contracts, tested mappings, credentials, approved routes, and recoverable runs are the foundation. A tool schema is another controlled interface to that foundation.

Expose a selected contract, not unrestricted credentials

A fictional vendor could expose a read operation with a schema derived from its records.list contract. The gateway around the tool would select an authorized customer profile from trusted application context. A model should not be able to switch to another customer’s production profile by inventing an argument.

{
  "name": "list_records",
  "description": "List records permitted by the current application context",
  "inputSchema": {
    "type": "object",
    "properties": {
      "resource": { "type": "string", "enum": ["customers"] },
      "limit": { "type": "integer", "minimum": 1, "maximum": 20 }
    },
    "required": ["resource"],
    "additionalProperties": false
  }
}

This is an illustrative tool schema for the vendor’s example, not a published Invokation API. The resource restriction reflects that fictional application’s permission decision. Other vendors would define their own operations, contracts, and scope rules.

Budget execution and review side effects

Planned controls include profile-scoped operation permissions, schema validation, bounded timeouts, concurrency and rate budgets, and limits on the number or cost of tool invocations. An agent loop should not be allowed to generate unlimited background work because each individual request is valid.

Separate reads from writes. A write can require explicit application or human approval before queuing, depending on its consequence. A queued run’s acceptance does not prove completion, and a retry after an ambiguous timeout can repeat an external side effect. The destination and adapter determine deduplication behavior.

Keep an inspectable trail

The same planned run history would expose trace IDs, selected profiles, mapping versions, attempt timing, delivery status, and redacted failures. Operators need to distinguish a bad model decision from a mapping failure, an authorization denial, or an unavailable target.

Audit history should record the authorization context and approval decision without unnecessarily retaining model prompts or confidential payloads. Redaction, access permissions, and retention remain design responsibilities, not automatic consequences of calling something a tool.

Model behavior still needs deliberate design

Schemas cannot guarantee that a model chooses the appropriate action or correctly interprets a result. Your application must define which users can invoke which operations, how trusted context is established, what confirmation is required, and what evidence is presented after execution.

Invokation is in development. This planned extension builds on the platform model, rather than promising that AI resolves enterprise semantics. Read the recovery guide before exposing any operation that changes external state.
