Retrieve a phone provisionings custom configurations

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=true, so 'Read-only' in the description is pure repetition and adds no value. Nothing is said about whether an empty result is an error, whether the payload is paginated, or what the configuration objects contain — the actual behavioral questions an agent would have.

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?

Two short sentences, front-loaded with the operation and no wasted preamble. The trailing 'Read-only.' is redundant with the annotations but costs little.

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?

With no output schema, the description is the only place return shape could be conveyed; the plural 'configurations' hints at a collection but nothing more is said about structure or emptiness. For a simple, fully documented GET this is marginally adequate, but it leaves the return contract unstated.

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% with only two parameters, including an enumerated response_format, so the schema carries the semantics. The description adds nothing about the id path parameter (e.g. whether it is the provisioning ID from placetel_list_provisionings), so the baseline 3 applies.

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 names a specific verb (Retrieve) and resource (a provisioning's custom configurations), so the purpose is discernible. However, it is a verbatim restatement of the title plus an HTTP path, and it does nothing to distinguish this read from the closely named siblings placetel_get_provisioning, placetel_upsert_provisioning_custom_configuration, and placetel_delete_provisioning_custom_configuration.

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?

There is no guidance on when to call this versus placetel_get_provisioning (which may already embed configurations) or the upsert/delete variants on the same sub-resource. The agent must infer usage entirely from the tool name.

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