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

No annotations provided, so description carries full burden. Discloses intelligent spelling correction and phonetic fallbacks beyond basic prefix matching. Could mention case sensitivity or empty prefix behavior, but current disclosure is good for a simple recommendation tool.

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, main purpose first, then additional features. No redundant words or filler. Highly efficient.

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?

Tool is low-complexity with 2 params and no output schema. Description covers core behavior and distinctive features. Could mention default max or ordering of results, but adequate overall.

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 baseline is 3. Description does not add extra meaning to 'prefix' or 'max' beyond the schema. No parameter-specific elaboration.

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?

Clear verb 'Get word suggestions' and resource 'partial input'. Description distinguishes from siblings by mentioning spelling correction and phonetic fallbacks, which are not found in synonym/rhyme tools.

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?

Implied usage from 'for a partial input' but no explicit when-to-use or when-not-to-use. Does not name alternatives from sibling list, although context makes it obvious this is for general completion.

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