users_get_user_subscription_request_history

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

With no annotations, the description must carry the full behavioral burden. It usefully discloses that results are capped at the recent 24 records and the GET/path implies a read-only operation, but it omits return shape, whether older history is retrievable elsewhere, and any auth/permission requirements.

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 description is short and front-loaded, leading with the endpoint and the core action. The trailing 'Tags: Users Controller' is boilerplate that adds no selection value, but overall the text is compact rather than verbose.

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 single-parameter read tool with no output schema, the definition is only minimally complete: it conveys the resource and the 24-record cap but says nothing about the response contents or how to retrieve older history, which an output-schema-less tool arguably should.

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?

There is 1 parameter with 0% schema description coverage, so the description must compensate. The embedded path template ({userId}) does tell the agent that userId is a path parameter identifying the target user, which is modest added value, but no format, type, or constraint details are provided.

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 and resource: fetching a user's subscription request history, and even adds scope ('recent 24 records'). It is clear what the tool does, but it does nothing to distinguish itself from the sibling tools user_subscription_request_history_get_subscription_re_1r7914 / _31zydo, which appear to cover overlapping ground.

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 explicit guidance on when to use this tool versus the near-identical sibling history tools, nor any stated preconditions. The only implicit context is the 'recent 24 records' scope, which hints at a bounded/tail view but is never framed as a usage rule.

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