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

With no annotations, the description carries the full burden, and it does disclose one useful trait: "No keys requested," implying no authentication is needed. However it says nothing about whether the call is read-only, what it returns, or any rate limits, so the disclosure is partial.

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 with no filler, but the telegraphic phrasing ("Free menu of paid consults") makes the front-loaded clause harder to parse than a plain statement would be.

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-param tool with no output schema, the description should clarify what the caller receives. It names three content categories (consults, A2A tasks, connect how-to) but leaves the return shape and the relationship to the paid siblings ambiguous.

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 takes zero parameters, so there is nothing for the description to disambiguate. Baseline of 4 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?

"Free menu of paid consults, A2A tasks, and connect how-to" gestures at the resource (a pricing/menu listing) but the phrasing is telegraphic and never states a clear verb like 'list' or 'get'. It is distinguishable from siblings such as oracle_ask or oracle_health only by inference, not by explicit contrast.

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 call this versus oracle_ask, oracle_diagnose_402, or any other sibling. The word "Free" hints it is a discovery entry point, but no condition, prerequisite, or alternative is stated.

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