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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=true, so safety is covered. The description adds only the fixed-endpoint framing and that ChannelOAuthId is resolved internally; it never says what happens if the AI task is still running (pending result vs. error), which is the single most important behavioral fact for a 'get task result' tool.

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?

The scope statement and endpoint identity are front-loaded and useful, but several sentences are pure boilerplate ('HGRApi functional documentation:', 'Search terms: ai gettaskresult') and the Purpose/Use when pair is redundant with itself. Roughly a third of the text could be deleted without losing information.

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?

An output schema exists, so return-value documentation is not required. However, for an async task-result retrieval the description omits completion/pending semantics and the pairing with the creating tool, leaving a real gap an agent must guess around; the rest (auth channel, body shape) is adequately covered.

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 baseline is 3, but the description adds information the schema lacks: the body is a GetTaskResultRequest whose main fields are TaskId (int) and ListingId (int), and 'Send the exact request payload in body' clarifies the calling convention. This meaningfully extends the generic 'HGRApi POST /api/AI/GetTaskResult request body' schema description.

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+resource: the 'get task result operation in AI optimization task management', and explicitly disclaims being a generic endpoint caller, which separates it from arbitrary POST callers. It does not, however, distinguish it from closely related siblings such as hgr_post_ai_createtask or hgr_get_ai_gettasks, so an agent still has to infer which one to reach for.

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 'Use when' sentence is circular, repeating 'use it when a client needs to run the get task result operation'. There is no guidance on when to call this versus hgr_get_ai_gettasks or hgr_post_ai_createtask, and no mention of the typical prerequisite (a TaskId returned by a prior create call) or of polling behavior.

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