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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint=false and destructiveHint=false, so safety is covered. The description adds the useful context that a link is tied to a Free Room Analysis request, but it omits whether the link expires, is single-use, or is reusable, which matters for a link-generating 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?

Two sentences with no clear front-loading: the opening sentence leads with vague framing ('a way to capture a room') instead of the concrete action (returns a scan/upload link). The second sentence mixes in promotional information about a Free Room Analysis request.

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 and no parameters, the description carries the full burden of explaining the returned link and its lifecycle, and it does not. An agent cannot tell from the description what to do with the result or how the link relates to asp_start_free_room_analysis.

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 tool takes no parameters, so the baseline is 4. There is nothing for the description to disambiguate beyond the schema's empty object.

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 says it will 'Get a way to capture a room' and mentions an app plus a personal link, but it never states plainly what the tool returns (a URL? a token? instructions?). It is distinguishable from the compute/recommend siblings only by implication, not by an explicit statement of the deliverable.

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?

There is no guidance on when to call this versus asp_start_free_room_analysis or the other siblings, no prerequisites, and no exclusions. The mention of LiDAR/Pro-device requirement comes across as marketing copy rather than an explicit usage condition.

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