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

No annotations are provided, so the description carries the full disclosure burden. It implies a read operation via 'Full detail', but says nothing about permissions, whether the endpoint must belong to the caller, error handling for unknown IDs, or rate limits. For a tool with zero annotation coverage this is a meaningful gap.

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?

Two short sentences, front-loaded with the purpose and followed by the one piece of operative guidance. Nothing extraneous.

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-param lookup with no output schema and no annotations, the description covers enough to call the tool but not enough to set expectations — it does not indicate what 'full detail' contains or what happens on a bad ID. Adequate but with clear gaps.

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 0% for the single endpoint_id parameter, and the schema gives no description. The description partially compensates by telling the agent where to obtain the ID (list_my_endpoints()), but adds no format, naming, or validity details for the value itself.

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: 'Full detail for one endpoint.' It clearly distinguishes itself from list_my_endpoints by contrasting singular vs. listing, and from create/delete/update siblings by implication. It stops short of naming a sibling alternative in an exclusionary way, but the purpose is unambiguous.

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?

Provides a prerequisite/workflow hint — obtain the ID from list_my_endpoints() — which is genuinely useful routing. However there is no explicit when-to-use vs. when-not guidance, and no mention of error behavior for invalid or foreign IDs.

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