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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior. The description adds useful context: requires templates:manage scope, maps to a GET endpoint, and shares PassFast billing/rate limits. There is no contradiction.

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 definition is compact and front-loaded with purpose. There is minor redundancy between 'Get a template' and 'Returns the full details...', but no material waste.

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 read operation, the schema, annotations, and description together cover scope, endpoint, idempotency, and return intent. No output schema exists, but 'full details' adequately conveys the result shape; error behavior is not specified.

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 100%, and both id and x_app_id are already explained. The description's only param contribution is showing id as the path segment via /manage-templates/{id}; baseline 3 is appropriate.

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?

States a specific verb and resource ('Get a template', 'full details of a single template'), and the GET /manage-templates/{id} mapping makes the operation unambiguous. The 'single template' wording distinguishes it from listTemplates without needing the schema.

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 explicit when/when-not guidance or named alternative tools, so an agent must infer from 'single template' that this is for fetching one template by ID. The scope and API-path notes are operational context, not selection guidance. This is adequate but not explicit.

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