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

With no annotations and no output schema, the description carries the full disclosure burden, and it delivers little. It implies a gated operation ("subscription required") and a change-driven trigger model, which are useful hints, but says nothing about whether the check mutates state, what happens on failure, or what a caller receives back.

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?

The description is a single short fragment with no padding, so it is concise, but it is under-specified rather than efficient. There is nowhere for the reader to go after the parenthetical, and no front-loaded statement of action.

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 tool with zero annotations, no output schema, and an undocumented required parameter, the description would need to explain invocation context, return behavior, and the subscription gate in detail. It supplies only a fragment and an access caveat, leaving the agent without enough to call 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?

The single parameter agent_id has 0% schema description coverage, so the description must clarify it and does not — no word on whose agent, in what format, or whether it identifies the checked target or the subscriber. A one-line note would have closed this gap entirely.

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?

"One change-driven alerting check" gestures at the resource (an alerting check) but never states a verb or what the tool actually does — evaluate, trigger, fetch, or list. Compared with siblings like verify_attestation or verdict_query, which have clear verbs, this reads closer to a label than a purpose. An agent cannot confidently determine the action.

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 only guidance is the parenthetical "(subscription required)", a prerequisite rather than a when-to-use rule. There is no indication of when to pick this over alert-adjacent siblings like panel_status or verdict_query, and no statement of what it does not cover.

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