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

No annotations are supplied, so the description carries the full burden. 'Get' implies a read, but nothing states whether results vary by room_type, whether omitted room_type returns defaults or all rooms, or whether the returned formulas are prescriptive or informational. For a lookup tool with zero annotation coverage, this is thin.

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?

A single front-loaded sentence that lists the returned data types with no filler. Every clause earns its place and nothing is buried.

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 one-parameter read tool with full schema documentation and no output schema, the description covers what the tool yields. It omits how room_type changes the output and where this sits relative to sibling guide tools, which an agent would still need to guess.

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%: the single room_type enum is fully documented in the schema, including that it targets light/circadian and acoustic optimization. The description does not add meaning beyond that baseline, so a 3 is appropriate.

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?

Names a specific verb ('Get') and resource ('residential circadian wellness window specifications') and enumerates the data returned: fabric GSM, blackout percentage, acoustic dampening, fullness sizing formulas. An agent knows exactly what content comes back, though it is not differentiated from siblings such as get_curtain_guides, which an agent could plausibly confuse with it.

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 when-to-use guidance at all. The description never says whether this is the right call versus get_curtain_guides or the other guide lookups, and gives no exclusion or prerequisite conditions.

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