create_trigger

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden. It discloses that the tool returns a URL and secret for external POST requests, and that it fires the workflow. This adds behavioral context beyond the input schema. However, it does not mention potential side effects (e.g., if overwriting is allowed) or error handling.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short (three sentences plus Args list), front-loaded with the main purpose, and contains no superfluous information. Every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple with two parameters. The description covers the return value (URL and secret) and parameter semantics. While it could mention error scenarios or prerequisites, it provides enough context for correct use given the presence of an output schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must explain parameters. It describes workflow_id as 'UUID of the workflow' and name as 'Human-readable name for the trigger', adding meaning beyond the schema's titles. Brief but sufficient for simple string parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Create an inbound webhook trigger for a workflow' with a specific verb and resource. It distinguishes from sibling tools like list_triggers, which list existing triggers, and other workflow management tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explains that the tool creates a trigger for external services to POST to, but does not provide explicit guidance on when to use it versus alternatives, nor does it mention prerequisites (e.g., workflow must exist) or conditions to avoid (e.g., duplicate names).

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
