get_webhook

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

No annotations are provided, so the description bears full responsibility. It mentions 'Returns webhook details' but does not disclose that this is a read-only operation, potential error conditions, authentication requirements, or rate limits. The minimal disclosure leaves the agent guessing.

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 two sentences, both front-loaded with purpose. It is concise with no extraneous words, though the second sentence listing return fields could be integrated or omitted if the output schema suffices. Still efficiently communicates core purpose.

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?

For a simple get operation with one parameter and an output schema, the description is minimally adequate. It covers the main action and return fields but lacks context on authentication, error handling, or how to obtain the webhook ID. It does not contradict annotations (none present).

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?

The input schema has 0% description coverage. The description adds that the tool retrieves 'by ID', implying the parameter is the webhook's identifier, but provides no further details on format, required properties, or valid values. This is marginally helpful but insufficient.

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 the action: 'Get a Trello webhook by ID' with a specific verb and resource. It lists the return fields (id, description, callbackURL, active), distinguishing it from sibling tools like list_webhooks (list all) and create/delete/update.

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?

No guidance on when to use this tool versus alternatives (e.g., list_webhooks), no prerequisites, and no indication of what the webhook ID should be. The description lacks any usage context or exclusions.

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