analytics_report_segments_get_instance

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

No annotations are provided, so the description carries the full burden of behavioral disclosure, and it discloses nothing. It does not state auth requirements, whether the operation is read-only (only inferable from 'GET'), rate limits, or error behavior for a missing id.

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, but the content is a verbatim endpoint path printed twice in parentheses, which is redundant noise rather than front-loaded signal. Brevity here reflects under-specification, not efficient communication.

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?

The tool is a simple single-resource GET with full schema coverage and no output schema, so it needs little, but the description still fails to say what an analytics report segment is or why an agent would fetch one. Naming only the HTTP route leaves the resource semantically opaque.

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%, so both the required 'id' and the optional 'fields_analyticsReportSegments' are fully documented in the schema itself. The description adds no additional syntax, format, or filtering meaning, so the baseline of 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 is just the raw endpoint path 'GET /v1/analyticsReportSegments/{id}' repeated twice, which restates the tool name rather than explaining what the resource is or what a 'segment' contains. It does convey a read of a single analytics report segment by id, but provides no purpose beyond what the 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 guidance on when to use this tool versus the many sibling 'get_instance'/'get_to_many' analytics tools, no prerequisites, and no indication of when it should not be used. The agent is left to infer everything from the URL.

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