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

Annotations already declare readOnlyHint=true, openWorldHint=false and destructiveHint=false, so the safety profile is covered. The description adds workspace scoping and the returned field set, but says nothing about volume, pagination, or whether archived/unpublished templates appear.

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 with no filler; the list of returned fields is compact and earns its space.

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, the description compensates by naming the fields returned and the workspace scope, which is enough for a parameterless list tool. Minor gap: no mention of ordering, pagination, or whether only published versions are returned.

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?

Zero parameters, so per the baseline the schema carries no semantics to clarify. The description still usefully frames the output fields (id, name, trade, published version), going slightly beyond the no-param baseline.

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 resource (workspace estimate templates) and enumerates the returned fields, which distinguishes it from the many sibling list_*_templates tools. It does not name those siblings explicitly, but the resource noun is unambiguous.

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 parenthetical hint that published templates 'can price a job from measurements' faintly implies a downstream use, but there is no explicit when-to-use, prerequisite, or routing to alternatives such as list_document_templates or list_proposal_templates.

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