soundex_code

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

No annotations are provided, so the description carries full burden for behavioral transparency. It describes the core function (generating a Soundex code) but omits details about input constraints (e.g., should 'text' be a single word?), output characteristics (string format, length), and any side effects or performance considerations. The description lacks sufficient behavioral context beyond the basic operation.

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 at 4 sentences, front-loading the main purpose, then usage context, then parameter details. Every sentence adds information without redundancy. It is well-organized and easy to parse quickly.

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?

For a simple tool with one parameter and an output schema, the description covers the essential aspects: what it does, when to use it, and what input to provide. However, it lacks detail on the output format (though the output schema exists, the description doesn't describe the return value). Given the low complexity, this is mostly complete but could include output format hints.

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?

The input schema has one parameter 'text' with no description. The tool description adds meaning by specifying 'the word to encode with Soundex', clarifying that the input should be a single word and indicating its purpose. This exceeds the bare schema information. Without schema descriptions, this added context is valuable.

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 generates a Soundex phonetic code for a word and explicitly mentions its use in name matching and phonetic indexing. It distinguishes itself from siblings like nato_phonetic by focusing on encoding entire words for similarity rather than representing letters. However, it doesn't specify the output format (e.g., length 4), which slightly reduces clarity.

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 a clear intended use case ('name matching and phonetic indexing') and explains that it's useful for finding similar-sounding names. However, it does not mention when not to use this tool nor discuss alternatives (e.g., levenshtein_distance for edit distance, nato_phonetic for letter-by-letter encoding). The guidance is present but basic.

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