sendgrid_list_templates

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

Annotations already declare readOnly, idempotent, openWorld and non-destructive, so safety is covered. The description adds only the 'dynamic' template qualifier (as opposed to legacy templates), and says nothing about pagination behavior, result count, or rate limits beyond what the schema's page_size implies.

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 front-loaded sentence of seven words with zero filler. Nothing is repeated from the name and no sentence is wasted.

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 simple read-only list tool with full schema coverage and rich annotations, this is minimally sufficient. It is missing two things an agent would want: how pagination beyond page_size is handled, and whether 'dynamic' excludes legacy templates.

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%, so both api_key and page_size (default 10, max 200) are already documented. The description adds no additional parameter guidance, which is acceptable given the schema does the work, but it is baseline only.

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 and resource ('List dynamic email templates') and qualifies the template type ('dynamic'), which is more precise than a bare 'list templates'. It does not explicitly distinguish itself from siblings like sendgrid_get_template or sendgrid_send_email, but 'list' vs 'get' is inferable.

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 indication of when to use this versus sendgrid_get_template, nor any note about paging through results before calling get_template. The agent must infer the workflow entirely from the tool name.

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