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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world). The description adds genuinely useful context beyond them: the call goes to 'a future release,' so the agent learns it produces no immediate capability and should not block on it, and should keep working with existing tools.

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, no filler, with the trigger condition front-loaded and the follow-up behavior second. Every clause earns its place.

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?

No output schema exists, yet the description adequately covers the trigger and the post-call instruction, and the schema handles the conversation_id threading. A brief note on what happens to the request (tracked vs. answered immediately) would close the remaining gap.

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%, so the schema already explains 'capability', 'context', and the conversation_id reuse rule. The description adds no parameter-level detail (e.g., how detailed 'capability' should be), 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 action (request a missing tool/capability) on a specific resource, and is unmistakably distinct from all infrastructure siblings like deploy_application or list_servers. An agent can tell instantly this is the meta-tool for unsatisfiable requests.

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?

Gives an explicit trigger condition: 'whenever the user's request cannot be satisfied by the available tools.' It also instructs to continue helping afterwards, which implicitly defines the fallback behavior. What's missing is guidance on repeated/batched calls, but the when-to-use is clear.

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