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

Beyond annotations, the description discloses important behavior: every word must match, results are ordered with title matches first, and each result includes title, URL and category. It also warns that UNOFFICIAL links are third-party sites rather than Air Force-run sites, which is valuable context an agent would not get from annotations alone.

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 three compact sentences, front-loaded with the core purpose and searchable fields. Every sentence contributes useful information, including matching behavior and the UNOFFICIAL caveat.

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 read-only search tool with an output schema, full schema coverage, and clear annotations. The description supplies everything an agent needs to invoke it correctly, including matching semantics and the meaning of UNOFFICIAL results.

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 100%, so the schema already documents both parameters. The description still adds meaningful query semantics by explaining that searches can target name, acronym, URL, category or purpose, and that every word must match.

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: search aflink.us for Air Force and DoD websites. It also specifies the searchable dimensions (name, acronym, URL, category, purpose) and gives concrete example queries, so an agent can immediately tell what the tool does.

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?

Usage is clear: search by words as typed into the aflink.us search box, with examples such as "mypay" and "travel voucher." There are no sibling tools or alternatives to distinguish from, but the description does not explicitly state when not to use the tool.

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