MySQL SOUNDEX

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the agent knows it's a safe read operation. The description adds that it uses phonetic matching (SOUNDEX), which is helpful but does not disclose any other behavioral traits like performance implications or result characteristics.

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 concise (one sentence) and front-loaded with the purpose. However, it could be more informative about usage without sacrificing brevity.

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?

Given the high parameter count (12) and many alias parameters, the description is too brief to provide adequate context. It does not explain the role of aliases, required parameters, or behavior when includeSourceColumn is true. An output schema exists but is not described.

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 description coverage is 100%, with each parameter having a short description (e.g., 'Alias for column'). The tool description does not add further meaning beyond the schema, so it meets the baseline but does not compensate for the complexity of 12 parameters including many aliases.

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 clearly states the tool finds rows with phonetically similar values using SOUNDEX. However, it does not differentiate from sibling tools like mysql_like_search or mysql_regexp_match, which also search for similar values but via different algorithms.

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 provides no guidance on when to use SOUNDEX versus alternative search tools (e.g., LIKE, REGEXP). It neither names conditions for use nor mentions when not to use this tool.

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