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

No annotations are provided, so the description carries the full burden. It discloses both the primary effect (stop scheduled runs) and an important behavioral trait (the operation is reversible via enable_monitor). It does not state whether currently executing runs are affected or whether any confirmation is required, but the core behavior is transparent.

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 with no filler. The primary purpose is first, and the reversibility note is second. Every word 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?

For a single-required-parameter, simple mutation tool with an output schema, the description covers the necessary context: what it does, and how it relates to enable_monitor. Nothing essential is missing for an agent 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%, so the schema already documents monitor_id and api_key. The description adds no new parameter-level semantics, which is acceptable given the schema's completeness. Baseline 3 is appropriate.

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 clearly states the action: disabling a monitor to stop its scheduled runs. It also anchors the tool relative to its obvious inverse sibling 'enable_monitor', removing ambiguity about what disabling means versus deleting or updating.

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 description communicates when to use the tool: when the monitor's scheduled runs should stop but the monitor should remain available for later use. It does not explicitly contrast with delete_monitor or list conditions, but the reversible framing provides sufficient context for an agent to choose this over destructive alternatives.

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