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

With no annotations, the description carries the full burden. It usefully discloses that the tool is stateless, does not write to D1, and does not touch lures. However, it omits return format, classification labels, thresholds, and any auth or rate-limit behavior.

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 a single dense sentence with no wasted words and is front-loaded with the core purpose. However, the jargon-heavy phrasing reduces clarity, and a slightly more structured breakdown would help an agent parse the key facts.

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 an 8-parameter classifier with no annotations and no output schema, the description is incomplete. It lacks return value information, parameter semantics for half the inputs, and usage guidance that would help an agent select and invoke it correctly.

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 coverage is 0%, so the description must compensate. It names five of the eight parameters (system_prompt, user_message, endpoint_path, max_tokens, and image payload length), but adds no semantic detail such as expected formats, required status, or the roles of vision_width, vision_height, and software_family_guess.

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 states a specific action ('classifier') and resource ('K-12 cheating wire') and lists the inputs it checks (system prompt, user message, endpoint path, max_tokens, image payload length). However, 'wire' is jargon and the description does not explicitly differentiate this classifier from the sibling query_k12_cheating_forensics tool.

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 gives no explicit when-to-use guidance, no alternatives, and no conditions that select this tool over siblings. It only implies a stateless classification context through behavioral constraints.

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