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

Annotations only declare destructiveHint=true, so the description carries the rest of the burden. It discloses the mutating nature and the backing endpoint (POST /v1/tasks) and enumerates the optional relationships it can establish, but says nothing about permissions, idempotency, or what is returned on success. Useful context, but not rich 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?

Two sentences, front-loaded with purpose and examples, then the endpoint reference. Efficient with no wasted filler, though the endpoint note earns less than the first sentence.

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 15-parameter mutation with no output schema and only a single annotation, the description gives a decent map of what can be set but omits the required 'title' emphasis, handling of the mutually relevant listing/reservation pairing, and any failure behavior. Adequate but with clear gaps given the tool's complexity.

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 all 15 parameters are already documented in the schema (including the category code mapping and date formats), which sets the baseline at 3. The description's summary of tie-to-listing/reservation, assignee, time window, category and cost adds orientation but no semantics beyond what the schema provides.

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 ('Create an operational task') and immediately grounds it with concrete examples (cleaning after checkout, maintenance job). This distinguishes it cleanly from the sibling hostaway_update_task and hostaway_list_tasks.

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 examples ('cleaning after a checkout or a maintenance job') imply when the tool is appropriate, and the optional scoping to a listing/reservation signals the intended context. However, there is no explicit routing guidance, e.g. when to use create_task versus update_task, or prerequisites like needing an existing listingMapId.

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