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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered without the description. The description adds that the response carries status and reason and that only the caller's own requests are visible, but says nothing about behavior for missing or foreign request IDs.

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 sentence, front-loaded with the verb and resource, with the ownership scope and ID provenance folded in without padding. Nothing is wasted and nothing needs reordering.

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 annotations covering safety and an output schema covering return shape, the description only needs to establish scope and ID provenance, which it does. The remaining gap is error behavior for unknown or non-owned request IDs, which is minor for a simple read.

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?

The single request_id has 0% schema description coverage, so the description carries the burden, and it does the most important part by telling the agent where the ID originates (space_create or space_request_channel). The ID format is only conveyed by the schema's regex pattern, which the description does not restate.

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 (read) and a precisely scoped resource (status and reason of your own Space or channel request), and it names the two producing tools (space_create, space_request_channel), which separates it from space_get and the listing tools. It stops short of naming an alternative tool an agent might confuse it with, so it is clear but not sibling-differentiating in the strongest sense.

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?

'Your own ... request' implicitly excludes requests belonging to other actors, giving a real usage boundary. It does not state what to do if the request is not yours or is still pending, and it names no alternative tool, so guidance is clear but not exhaustive.

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