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

The readOnlyHint annotation already establishes this is a safe read, so the description's burden is light. It contributes the API endpoint mapping, which helps with error interpretation, but says nothing about behavior on a missing or malformed id, nor what the returned payload contains. Adequate with annotations, but no extra behavioral depth.

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 primary statement of purpose front-loaded. The endpoint reference is compact and diagnostically useful rather than redundant padding.

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 single-parameter read tool whose safety profile is carried by annotations and whose parameter is fully documented in the schema, this is close to complete. The only meaningful omission is a note on what the response contains or what happens when the id does not resolve.

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?

With one required parameter and 100% schema description coverage, the baseline of 3 applies. The description adds no semantics for task_id beyond echoing it in the endpoint path, and the schema already tells the agent where to obtain the value.

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 names a specific verb and resource ("Get one task by id") and adds the underlying API route, so there is no ambiguity about what the tool returns. It is clear it fetches a single record, which implicitly separates it from doorloop_list_tasks, but it never names that sibling or any other to make the contrast explicit.

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?

Usage is only implied: fetch a task when you have its id. The description gives no explicit guidance on when to prefer this over doorloop_list_tasks, and no prerequisite or failure condition (e.g. an unknown id) is mentioned. The only real routing hint, "from the matching list tool", lives in the schema rather than the description.

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