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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds the workspace-scoping context, which is useful, but it does not disclose behavioral details like pagination defaults, filtering semantics, or result shape. No contradiction with annotations, so a modest 3 is appropriate.

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 eight-word sentence that front-loads the verb and resource with zero filler. Every word earns its place, and the length is appropriate for a tool of this simplicity.

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 read-only list tool, the combination of readOnlyHint=true and fully documented optional parameters is mostly sufficient. The main gap is that there is no output schema and no note about what a returned template record contains or how pagination behaves, so an agent must discover the response shape by experimentation.

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% — all four parameters (page, search, per_page, account_id) are documented with meaningful descriptions, including the default behavior for account_id. The description adds no parameter-specific detail, so the baseline of 3 applies.

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 ('List'), resource ('document templates'), and scope ('available in the workspace'). The resource term inherently distinguishes it from siblings like assinafy_list_documents and assinafy_get_template, though it does not explicitly name them the way the HIGH calibration example does.

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 usage context is implied: call this when you need to see which templates exist in the workspace. However, there is no explicit when-to-use/when-not-to-use guidance or mention of alternatives, and with 13 siblings such as get_template and create_document_from_template, explicit routing would reduce ambiguity.

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