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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, covering the safety profile. The description adds the useful detail that each template exposes its arguments and option tiers (implying a nested return shape), but does not describe scope (workspace-wide), pagination, ordering, or whether inactive templates are included.

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 that front-loads the resource and then enumerates the salient fields. Nothing is wasted, though it reads as a noun phrase rather than an imperative and lacks a terminating verb describing the action.

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 zero-parameter read-only list tool with full annotation coverage, the description is close to sufficient but omits ordering and scope (whether the list spans the whole workspace or a default subset). It also fails to help disambiguate from template-list siblings, which an agent choosing among many list_* tools would need.

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 zero parameters, so per the rubric the baseline is 4. The schema is empty (100% coverage trivially), and the description correctly adds no parameter detail because there are none to describe.

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 clear verb implicit (list/retrieve) and resource (the workspace's proposal templates), and enumerates the fields returned (id, title, description, arguments with defaults, option tiers). It is distinguishable from siblings like list_proposals or list_document_templates by naming 'proposal templates' specifically, though the sibling list has several near-neighbors (list_estimate_templates, list_document_templates) that it does not explicitly differentiate from.

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?

No when-to-use guidance, no mention of alternatives, no prerequisites or exclusions. The description only names what is returned, leaving the agent to infer that this is the tool for discovering proposal templates without any routing cues relative to list_document_templates or list_estimate_templates.

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