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

Annotations already declare destructiveHint=true, idempotentHint=false and openWorldHint=false, so the safety profile is covered; the description adds the return contract (id and uuid), which annotations do not provide. It does not explain why creation is flagged destructive, whether duplicate titles collide, or anything about the shape of the map payload — gaps that matter for a non-idempotent write.

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?

Two short sentences, zero filler, with the payload source stated before the return values. Nothing needs to be removed; the only quibble is that brevity here borders on under-specification.

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?

No output schema exists, and the description helpfully names the two returned identifiers. But for a three-parameter, non-idempotent write with a free-form nested object and 0% schema coverage, the definition leaves the agent guessing about payload structure and collision behavior.

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 carries the full burden; it only restates the `seliee_templates` parameter as a "key/value map." Nothing explains what keys/values are valid in that nested free-form object, what format `seliee_template_language` expects (ISO code? locale?), or any constraint on the title.

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?

Names a specific verb+resource ("Create a new seliee_template") and qualifies the source of data ("from an explicit `seliee_templates` key/value map"), which implicitly separates it from the sibling create_template_from_base. It stops short of naming that sibling explicitly, so differentiation is inferable rather than stated.

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 explicit when-to-use or when-not guidance, but "from an explicit key/value map" implies the alternative: use create_template_from_base when starting from a base. The agent must infer that from a sibling name it can only see in the tool list.

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