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

Annotations already declare readOnly, idempotent, non-destructive, closed-world behavior, so the safety profile is covered. The description adds useful payload depth (subtasks, comments, history are included), but the trailing 'Free.' is ambiguous and unexplained, leaving cost/quota behavior unclear.

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?

One compact sentence that front-loads the core purpose and enumerates return content with zero filler. The standalone 'Free.' fragment is unexplained and slightly undermines an otherwise tight phrasing.

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?

With no output schema, the description carries the burden of describing return content, and it names the included sections (description, links, subtasks, comments, history). It stops short of noting pagination or error behavior for a missing task, but is otherwise adequate for a simple getter.

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?

There is a single parameter with 100% schema description coverage; the schema already documents the 'WEB-12' style identifier or task_id. The description adds no additional meaning about the parameter, 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?

The description states a specific action ('One task in full') and enumerates the payload (description, links, subtasks, comments, history), which distinguishes it from write siblings like tasks_update. It does not explicitly contrast with tasks_list, though 'one task' implies the singular counterpart.

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 implied by the singular framing ('One task'), suggesting it's the tool for fetching a single task rather than a list or mutation. There is no explicit when-to-use statement or named alternative (tasks_list) to route the agent.

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