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

No annotations are provided, so the description carries the full burden. 'Returns' implies a read-only operation, and the description usefully discloses that fulfillment updates are appended to the record over time (a mutation-by-drift behavior) and that invoice links are included, but it omits auth requirements, rate limits, and whether status transitions are delayed or cached.

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 sentences with no filler; the return contents are front-loaded and the behavioral note about fulfillment updates follows compactly.

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?

With no output schema and no annotations, the description does the necessary work of naming the returned fields and the evolving fulfillment record. It is largely complete for a one-parameter read, though it stops short of addressing error cases (e.g., unknown order_id) or freshness of the status.

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?

A single parameter with 100% schema description coverage, so the schema already documents order_id and its origin. The description adds no syntax, format, or provenance detail beyond what the schema states, which is the baseline-3 case.

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 and resource ('get_order' returns order payment status), and enumerates the returned fields (payment state, amount, invoice link), which separates it from get_quote and accept_quote. It does not explicitly name those siblings, so differentiation is implied 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-to-use guidance. The only workflow hint ('order_id returned by accept_quote') lives in the schema, not the description, so the agent must infer that this is the post-acceptance status check.

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