tinyurl_analytics_report

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

With no annotations, the description usefully discloses the read-only GET nature, the required 'Analytics' token permission, and that optional parameters are 'validated and bounded'. It stops short of return shape, pagination, error behavior, or rate limits, which matter for an analytics endpoint with no output schema.

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?

Three compact sentences, front-loaded with the verb, resource, and endpoint. The dense phrasing ('to, interval, alias, domain, tag and location region are validated and bounded') is efficient, though slightly telegraphic.

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?

Covers endpoint, auth scope, required inputs, and validation, which is solid for a request-side definition. However, with eight parameters, no annotations, and no output schema, an agent still has no picture of what a report returns or how large it might be.

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 coverage is 100%, so all eight parameters are already documented in the schema, including the 'Timeline bucket size only' and 'Location report only' scoping notes. The description largely restates that scoping rather than adding new meaning, 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?

States a specific verb and resource ('Read one fixed TinyURL analytics report over GET /analytics/*') and enumerates the seven concrete report types, which separates it from sibling tinyurl_analytics_raw_logs and tinyurl_analytics_status. It does not name those siblings explicitly, so differentiation is implicit rather than spelled out.

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?

The description establishes that report is the selector and that from is required, and it hints at per-report applicability ('location region'). But it never says when to pick this over tinyurl_analytics_raw_logs or tinyurl_analytics_status, nor what happens when an inapplicable parameter is supplied.

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