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

Annotations already declare readOnlyHint=true, so the safe-read profile is covered by structured data. The description adds the underlying REST endpoint as a traversal hint but says nothing about not-found behavior, error modes, or how the 'depth' hydration affects the response.

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, zero filler, with the core purpose front-loaded and the endpoint detail trailing. Nothing to trim.

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 simple single-record read this is mostly sufficient, but with no output schema the description does not hint at the return shape or what hydration depth yields, and it is silent on missing-id behavior. Complete enough to invoke, not complete enough to predict the result.

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%: 'id' and 'depth' (including the 0-2 range meaning) are fully documented in the schema. The description adds no additional parameter meaning beyond that, so the baseline of 3 applies.

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 ('Get') with resource ('a single task') and scoping ('by id'), which cleanly separates it from the sibling twenty_list_tasks and from the create/update task tools. The REST endpoint mapping reinforces exactly what the tool retrieves.

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?

Use is implied by the singular 'by id' phrasing and the sibling set (lists vs. single gets vs. updates), but there is no explicit statement of when to use this over twenty_list_tasks or what to do when an id is unknown. Adequate inference, no explicit guidance or exclusions.

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