list_endpoint_manifest

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

No annotations are present, so the description carries the full burden of behavioral disclosure. It only says 'list,' which implies read-only, but does not disclose whether this reads a persisted manifest, requires authentication, or returns live vs. cached coverage data. It also doesn't describe any failure or side-effect behavior beyond the verb itself.

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?

A single compact sentence with no filler. The actionable verb is front-loaded and every remaining word contributes meaning, making it easy to scan.

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 zero-parameter list operation with an output schema present, the definition is nearly complete. The main gap is the ambiguity of 'scaffold,' which leaves room for uncertainty about what exactly is being enumerated and how it relates to drift tracking.

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?

The tool has zero parameters and schema description coverage is 100%, so there is no parameter burden for the description to carry. Baseline of 4 is appropriate because the description doesn't need to explain arguments that don't exist.

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 ('List') and resource ('endpoint coverage scaffold') with a clear purpose ('for drift tracking'). However, 'scaffold' is somewhat jargon-y and the description does not contrast it with sibling listing tools such as list_capabilities or list_tool_catalog, so it falls short of a 5.

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 phrase 'for drift tracking' implies when the tool is useful, giving some contextual guidance. But it provides no explicit when-not-to-use guidance or alternatives, and with several list-style siblings available, the agent must infer which tool is appropriate.

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