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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is fully covered without the description. The description adds only domain framing (holidays/special hours) and says nothing about ordering, pagination, or what an override contains, so it is adequate but thin once annotations are accounted for.

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?

A single well-formed sentence that leads with the verb and resource and embeds the clarifying example compactly. No filler, though it is almost too terse to be maximally useful.

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 read-only list tool whose annotations carry the safety profile and whose schema fully documents parameters, the description is minimally sufficient. It omits return-shape expectations and pagination behavior, and with no output schema present, a little more context on the returned overrides would have helped.

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 calendarId, from, and to are all documented in the schema itself, making 3 the baseline. The description's mention of 'date-specific' hints at the from/to filtering but adds no syntax or semantics beyond what the schema already states.

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 (List) and resource (date-specific availability overrides for a calendar), and the parenthetical clarifies the domain with concrete examples (holidays, special hours). It does not explicitly contrast with siblings like neuron_set_override or neuron_delete_override, but the read semantics are unambiguous.

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?

There is no guidance on when to use this versus alternatives such as neuron_get_availability, neuron_get_available_slots, or neuron_team_availability, nor any stated prerequisites beyond the required calendarId. Usage must be inferred 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.
