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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds that templates carry arguments with defaults and option tiers, which is useful context, but it says nothing about workspace scoping, pagination, or filtering behaviour.

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 compact sentence with no filler, and the resource is front-loaded before the field list. It is efficient, though being a fragment it lacks the crisp verb-first framing that would make it self-contained.

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 parameterless read-only list tool with no output schema, the field enumeration (id, title, description, arguments with defaults, option tiers) largely substitutes for the missing return schema. The remaining gap is the absence of any routing guidance relative to sibling list tools.

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 clarify beyond the empty schema, and it correctly does not invent parameters.

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 names the resource ('the workspace's proposal templates') and enumerates the fields it exposes, so the agent knows what it returns. However, it is a bare noun phrase with no verb, relying on the 'list_' prefix in the name, and it does nothing to distinguish itself from close siblings like list_proposals, list_estimate_templates or list_document_templates.

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, no prerequisite, and no mention of alternatives. An agent cannot tell from the text when to call this rather than list_proposals or list_estimate_templates, so it must infer usage purely from the name.

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