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

Annotations already declare readOnlyHint, idempotentHint and openWorldHint=false, so the safety profile is covered. The description adds one useful behavioral detail — the catalog contains only public templates — but says nothing about result size, pagination, or filtering behavior despite five filter parameters.

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?

Short and front-loaded, with the core action in the first sentence and the browsable URL as a compact trailing pointer. 'Templates are ready-made projects' is mild filler but does ground the term.

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 with no output schema and a fully documented schema, the description is adequate but thin. It omits what a result looks like and how filtering interacts, which an agent choosing between five optional filters would benefit from.

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 all five filters (tag, type, locale, search, category) are already documented in the schema, including the 'convo or poll' values for type. The description adds no additional parameter meaning; baseline 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) and resource (the public template catalog), which clearly separates it from get_template and clone_template in the sibling set. It does not explicitly name those siblings, so it stops short of full differentiation.

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 line 'Starting from one is almost always better than writing a script from nothing' nudges toward using templates, but gives no guidance on when to call list_templates versus get_template or clone_template, and no exclusions or prerequisites.

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