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

Annotations declare idempotentHint=true and destructiveHint=false, so the description's value is in the operational details it adds: a hard rate limit of one call per 5 minutes, and per-call payment via x402 when payments are enabled with a pointer to quantum_pricing. It does not say what the rebuilt watchlist looks like or what happens to entries that are dropped.

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: the action and its scope first, then the operational constraints. Every clause carries information an agent needs before calling.

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, non-destructive, idempotent maintenance trigger with annotations covering the safety profile, the description supplies cadence, throttling, and cost. The only gap is the absence of any hint about the response shape, which matters somewhat since there is no output schema.

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 no parameters at all, so there is nothing for the description to disambiguate; the baseline for a zero-parameter schema applies. The rate-limit and payment context is arguably the only 'input' an agent must reason about, and that is covered.

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+resource: 'Re-check every enrolled agent now and rebuild the watchlist.' The scope ('every enrolled agent', 'rebuild the watchlist') implicitly distinguishes it from single-agent siblings like inspector_check and read-only siblings like inspector_watchlist, though neither is named explicitly.

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 clear context on when this fires (manual trigger, plus the automatic hourly cadence) and the constraint that selects its viability ('At most once every 5 minutes'). It stops short of naming the alternative to use when a single agent re-check is wanted, which is the main remaining ambiguity.

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