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

No annotations are provided, so the description carries the burden. It discloses the return shape and hints that get_spell holds the 'freshest' detail, implying get_talents may be less current, but it omits permissions, rate limits, or whether the list is complete for a class/spec.

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?

Three short sentences, front-loaded with the purpose and return fields, then sequencing and a related-tool pointer. No wasted text.

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?

There is no output schema, but the description compensates by enumerating the returned fields. For a no-annotation read tool the main remaining gap is parameter value formatting, which neither schema nor description covers.

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% for both required params, so the description must compensate. It only says 'for a class/spec', which restates the parameter names without giving expected value format (class name vs id) or valid values. Minimal added meaning.

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 (selectable talents) scoped to class/spec, and enumerates the returned fields (id, name, effect, spell id, sub-tree, hero tree, choices). It is clearly distinguishable from generate_build and get_spell, which it names.

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?

Gives explicit sequencing guidance ('Call this before generate_build so you know the talent names') and routes spell-level detail to get_spell. It's clear context for use, though it states no when-not-to-use conditions.

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