Inbox API: Inbox details

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is carried by structured data. The description adds real value beyond that with the endpoint path (confirming a single-resource fetch) and the note that Persian/Arabic-Indic digits may appear in IDs and numbers unchanged, which is useful for input normalization. It still says nothing about response content or error behavior.

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 purpose is front-loaded in the first clause, followed by the endpoint and a compact encoding note. It is appropriately short and every sentence carries some information, though the Persian/Arabic-Indic digit note reads as boilerplate and slightly dilutes focus.

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 remains the only source for return-shape information, and it never says what "details" an inbox returns. For a single-parameter read tool whose annotations already cover the safety profile, this is adequate but leaves a real gap around what the caller receives.

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% for the single inbox_identifier parameter, so the baseline is 3. The endpoint path in the description implicitly confirms it is a path parameter, but no additional syntax, format, or sourcing guidance is provided beyond what the schema already states.

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 states a specific verb+resource ("Get the details of an inbox") and even pins the underlying endpoint, so the operation is unambiguous. However, the sibling list contains gapify_get_inbox as well as gapify_list_inboxes, gapify_create_inbox, and gapify_update_inbox, and nothing in the description distinguishes this "client" variant from the platform-side get. The purpose is clear but sibling differentiation is absent.

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, no stated prerequisites, and no named alternative. The description does not tell an agent when to prefer gapify_client_get_inbox over gapify_get_inbox or gapify_list_inboxes, which is exactly the ambiguity a sibling-heavy toolset creates.

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