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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds the negative clarification 'Does not start a timer,' which is useful context. It does not describe the return content beyond 'short feature and limits summary,' but with annotations and an output schema, a 3 is appropriate.

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, front-loaded with the core action and immediately followed by the key parameter guidance and a negative clarification. No waste.

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?

An output schema exists, so return values need not be explained. The description covers purpose, the detail parameter usage, and a key behavioral boundary. Minor gap: it doesn't explicitly differentiate from sibling info tools.

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 coverage is 0%, so the description should compensate. It mentions the 'detail=full' value and identifies summary as the default, which adds some meaning over the enum in the schema. However, it doesn't explain what 'full' contains versus 'summary' beyond 'complete reference.'

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 ('Get a short feature and limits summary') and clarifies what it is not ('Does not start a timer'). It is distinguishable from siblings like get_integrations and get_preset, but the description doesn't explicitly position itself against those siblings.

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?

Implies the default is summary and that detail=full should only be used for the complete reference. This gives some usage context, but there is no explicit when-to-use vs alternatives among siblings like get_integrations.

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