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

Annotations already cover the safety profile (not read-only, idempotent, non-destructive, open-world), and the description adds meaningful context beyond them: what comes back (updated report, 3D link, corrective Dynamo script) and the crucial constraint that sending names does not alter networks, parts, or corrections. It stops short of describing error behavior or how partial/omitted names are validated, so not a 5.

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?

Front-loaded with the core action and the return value, then workflow instructions. Slightly repetitive: 'you are naming what the tool measured; you are not changing what it measured' restates the later 'Nothing you send here alters a network, a part, or a correction.'

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?

No output schema exists, and the description fully covers what is returned (updated report, 3D link, Dynamo script) plus the required follow-up read. Nothing an agent needs to call this correctly is missing.

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% and both params have clear schema descriptions, so the schema does the heavy lifting. The description reinforces that names are proposals rather than mutations but adds no syntax or format detail beyond the schema.

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?

States a specific verb and resource ('Apply the names you propose, and get back the updated report') and immediately frames the tool against its read counterpart. An agent can tell this is the naming/write step of an IFC workflow without opening the schema.

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?

Explicit workflow guidance: give the user the 3D link, disclose which names are proposals, and after the user has been in the 3D view call read_ifc_networks again with the same token. It names the alternative tool and the condition that selects it.

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