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

With no annotations, the description carries the burden and does surface the key operational constraint: a registered-user JWT access_token is required. It does not say whether an unknown or unauthorized task_id produces an error versus an empty result, nor does it mention any rate limits or side effects (though the operation reads as non-mutating).

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 with zero filler; the primary action appears first and the auth requirement second. Nothing is redundant.

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 two-parameter read tool with no output schema and fully described parameters, the description covers purpose, return fields, and the authentication prerequisite. Only error behavior for invalid or missing task ids remains unspecified, which is minor.

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 100%, and the schema already documents both task_id and access_token including the registered-user JWT requirement. The description's parenthetical restates that constraint rather than adding format or acquisition details, so the baseline 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?

The description gives a specific verb and resource ('Get task detail by id') and names the returned fields (status, result, error), so an agent knows exactly what it retrieves. It is distinguishable from the sibling list_tasks, but it does not explicitly contrast itself with list_tasks or create_task.

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: by-id retrieval suggests you need an existing task_id, which list_tasks would supply. No explicit when-to-use or when-not-to-use guidance, and no named alternative for cases like looking up many tasks.

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