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

No annotations are provided, so the description carries full burden. It states 'Get all scheduled downtimes', implying a read operation, but lacks details on permissions, rate limits, pagination, or return format. For a tool with zero annotation coverage, this is insufficient behavioral disclosure.

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, efficient sentence: 'Get all scheduled downtimes.' It is front-loaded with the core action and resource, with zero wasted words. Every part of the sentence contributes directly to understanding the tool's purpose.

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?

Given the lack of annotations, no output schema, and a simple read operation, the description is incomplete. It does not address behavioral aspects like what 'all' entails (e.g., pagination, filters), authentication needs, or error handling. For a tool in a complex sibling set, more context would help the agent use 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 input schema has 0 parameters with 100% coverage, so no parameter documentation is needed. The description does not add parameter information, which is appropriate given the schema completeness. Baseline is 4 for zero parameters, as no compensation is required.

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 'Get all scheduled downtimes' clearly states the verb ('Get') and resource ('scheduled downtimes'), making the purpose evident. It distinguishes from siblings like 'get_downtime' (singular) by specifying 'all', though it doesn't explicitly contrast with other downtime-related tools like 'downtimes_list' or 'create_downtimes'.

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 provides no guidance on when to use this tool versus alternatives. With siblings like 'get_downtime' (singular), 'downtimes_list', and 'create_downtimes', there is no indication of context, prerequisites, or exclusions. The agent must infer usage from the name alone.

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