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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive, so the safety profile is covered. The description does add one genuinely useful behavioral fact — that the bulky template body field is omitted from results — but says nothing about pagination behavior, result ordering, or empty-result handling despite exposing page/per_page.

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 that leads with the action and then the filters, with no filler. It loses a point for the awkward self-referential 'seliee_templates (without the bulky seliee_templates field)' phrasing that reads as an unresolved template artifact.

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?

With no output schema, 0% schema coverage, and four optional parameters, the description should explain pagination and the shape of returned items. It covers filters and the omitted field but leaves paging behavior and the scope of 'templates' unexplained, so an agent cannot fully predict results.

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 0%, so the description must carry the load. It usefully explains title_query as a substring match and language as an exact match with a tr_TR example, but page and per_page (half the parameters) get no mention at all, leaving pagination semantics undocumented anywhere.

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 (templates) plus filtering capability, so the basic purpose is unambiguous. However, among siblings like list_wp_templates, list_sms_templates, and list_customer_invoice_templates, the description never says which template family this covers; the odd 'seliee_templates' token reads as a placeholder rather than disambiguation.

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 phrase 'optionally filtered by title substring and/or exact language' implies the browsing/filtering use case, but there is no explicit when-to-use guidance, no exclusion of alternatives (get_template for a single record, the other list_* template tools), and no note on when filtering vs paging is appropriate.

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