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

With no annotations, the description bears the full disclosure burden. It adds one useful data caveat (the judge field is as in the source), but says nothing about behavior for an unknown doc_id, the returned metadata structure, or whether the call is purely read-only beyond what the name implies.

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 with the purpose front-loaded and no padding. The judge caveat is tersely worded but earns its place as real domain context.

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?

This is a simple one-parameter getter with no output schema, so the description only needs to cover purpose, input format, and return meaning. Purpose and input format are handled, but 'metadata' is left vague and error behavior is unaddressed.

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% and the schema allows either string or integer, so the description usefully constrains doc_id to an integer of digits 0-9. It does not clarify how a string input is treated or where a valid doc_id comes from.

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 verb and resource: retrieve the metadata of a single decision by doc_id. That clearly separates it from the retrieval-by-search siblings such as search_decisions, though it never names those siblings explicitly.

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?

It implies you need a doc_id in hand, but gives no explicit when-to-use or when-not-to-use guidance and never points to search_decisions for the case where the caller does not already have an ID. The agent must infer the routing itself.

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