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

Only destructiveHint=true is provided, so the description must carry behavioral weight — and it does add real context beyond the annotation: that this 'can clear or trigger alerts' and that pings hit a specific telemetry endpoint. It stops short of explaining the effect of individual states (e.g. that 'pause' halts monitoring) or auth needs.

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 compact sentences that front-load purpose, then behavior, then the endpoint template. Slightly dense but every clause (states, alert side-effects, URL shape) 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?

With 6 parameters, no output schema, and only a destructiveHint annotation, the description covers purpose but omits per-state semantics (what 'pause'/'fail' do to alert state) and any auth/URL-key requirement. Adequate to invoke, but thin for a state-driven alerting mutation.

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 every parameter including host, metric, series, and message is already documented. The description only restates the state enum and the state= query fragment, adding no syntax or format meaning beyond the schema — 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 verb and resource ('Reports a telemetry event ... for a monitor'), enumerates the exact state values, and the telemetry-ping role is clearly distinct from the CRUD siblings (create/get/list/update/delete_monitor). An agent can select this over any sibling without opening the schema.

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?

Usage is implied by 'records job/heartbeat activity' and the state list, but it never states when to choose this over cronitor_update_monitor or that it is the only tool for reporting runtime events. No explicit when-not or alternative routing is given.

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