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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds only the underlying endpoint (GET /template) and the optional type narrowing; it says nothing about pagination behavior or auth, which is a modest addition on top of the annotations.

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 short sentence followed by the endpoint, with the core purpose front-loaded and no filler. The raw HTTP verb/path adds little for an agent and is the only slightly expendable element.

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?

All four optional parameters are documented in the schema and annotations carry the safety profile, so the essential call mechanics are present. However, with no output schema the description never indicates the shape of the returned template list or how paging metadata (next_skip) surfaces, leaving that gap.

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%, with skip, sort, type and limit all self-documented including the next_skip pagination hint, so the baseline is 3. The description restates the type filter but adds no syntax, format, or default 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 (List) and resource (message/email templates) scoped to the account, and notes an optional type filter. It clearly contrasts with the singular sibling tokeet_get_template by virtue of 'list' vs 'get', though it never names siblings explicitly.

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 and no reference to alternatives such as tokeet_get_template for fetching a single template. 'Optionally of one type' is a filtering hint, not usage guidance, so the agent must infer when this tool is appropriate.

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