Behavior2/5

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

With no annotations provided, the description must carry the full burden of behavioral disclosure. It only states 'List dynamic email templates' but does not reveal any behavior: whether it is read-only, rate limits, pagination, or what happens if no templates exist. This is insufficient for an agent to understand the tool's behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very short (one sentence) and contains no unnecessary words. However, it is too terse and lacks important details that could be added without increasing length significantly. Still, it earns points for being concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 2 parameters and no output schema, the description is minimally acceptable but incomplete. It does not specify return format, pagination, error handling, or any other contextual details. A more complete description would at least hint at what the agent can expect as a response.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% description coverage, so the baseline is 3. The description does not add any additional meaning beyond what the schema already provides for api_key and page_size. No defaults or constraints beyond schema are explained.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool lists dynamic email templates in SendGrid. It identifies the resource and action, and distinguishes it from siblings like sendgrid_get_template (single template) and sendgrid_list_contacts (contacts). However, it does not specify details like whether it returns all templates or paginated results.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. For example, it does not mention that sendgrid_get_template should be used for retrieving a single template by ID, or that this tool is for listing all dynamic templates. The description is standalone without context on usage.

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