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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and closed-world behavior, so safety is covered structurally. The description adds genuine behavioral context beyond that: the call is a router, it returns the tool-mapped menu, and the intent is recorded without affecting the answer. It does not mention any rate limits or output size characteristics, but for a no-arg helper the disclosure is solid.

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 tight sentences: the first front-loads the trigger conditions, the second explains the return value and its routing purpose. No filler and no repetition of the name or title.

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?

With an output schema present, the description need not spell out the response shape, and annotations fully cover the safety profile. Triggers, the fallback condition, and the routing payoff are all present, so an agent has everything needed to invoke it correctly.

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 description coverage is 100% and the single optional 'context' parameter is fully documented in the schema, including that it is intent-only and never changes the answer. The description adds nothing parameter-specific, which is acceptable given the schema does the work; 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?

The description states a concrete behavior: it returns the full menu of questions the server answers, each mapped to the answering tool. That is more specific than a tautology and tells an agent exactly what comes back. It does not, however, differentiate itself from the sibling 'get_more_tools', which is presumably the other discovery-style tool, so sibling separation is incomplete.

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?

It gives explicit trigger conditions (greeting, connectivity/liveness test, 'what can you do') plus a catch-all rule for any message too general to match a specific tool. That is clear when-to-use guidance. It stops short of naming an alternative tool or stating when NOT to call it in favor of a sibling like get_more_tools.

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