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

Without annotations, the description explains the output (NPC packet) and the intended behavior (improvise dialogue from it). It does not mention side effects or permissions, but for a read-like tool this is acceptable.

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?

The description is concise with two sentences, front-loading the key output. However, the first sentence is dense and could be clearer for the parameter.

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 dialogue tool with one parameter and no output schema, the description covers the core purpose and how to use the output. It lacks input parameter explanation but is otherwise sufficient.

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?

The description does not explain the 'npc_key' parameter at all, leaving the AI to guess its meaning. With 0% schema description coverage, the description fails to compensate for this gap.

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?

The description clearly states the tool's purpose: it provides an NPC packet (personality, sanity, etc.) for improvising dialogue. This distinguishes it from sibling tools like 'attack' or 'buy' which have different actions.

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 description instructs the AI to improvise dialogue FROM the packet and never against it, providing clear usage guidance. However, it does not explicitly mention when not to use this tool or suggest alternatives.

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