Update a phone provisionings

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

Annotations already declare the mutation profile (readOnlyHint=false, destructiveHint=false, idempotentHint=true). The only extra signal is the PUT verb, which vaguely implies replace-style semantics, but the description never says whether omitted body fields are cleared or preserved, nor whether any permission is required. Beyond the endpoint string it adds essentially nothing.

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?

It is short and front-loaded, so no waste in length, but the second sentence is a bare endpoint reference that adds little for an agent, and the grammar ("a phone provisionings") undermines clarity. Brevity here reflects under-specification rather than discipline.

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?

This is a 10-parameter mutation tool with no output schema, and the description says nothing about which fields are updatable, whether partial updates are allowed, or what the call returns. Annotations cover the safety profile, but the operational behavior of the update itself is left entirely to the schema and guesswork.

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 enums documented for codec, locale, encryption, and response_format, so the schema carries parameter meaning on its own. The description contributes no additional semantics (e.g., which fields are optional in practice or how lines/keys interact), so 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 restates the title almost verbatim ("Update a phone provisionings") and adds only the raw HTTP endpoint. It states a verb and resource, but conveys no scope, no updatable fields, and no differentiation from siblings such as placetel_create_provisioning or placetel_reconfigure_provisioning beyond what the tool name already implies.

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 when-to-use guidance and no mention of alternatives. An agent is not told when to call this versus placetel_reconfigure_provisioning, placetel_upsert_provisioning_custom_configuration, or placetel_get_provisioning for inspection.

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