find_material_match

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

The description discloses the fuzzy-matching behavior, case-insensitivity, and color-based preference for tie-breaking. However, it does not specify the output format (e.g., returns a single entry or list), behavior on no match, or whether the operation is read-only. With no annotations, these gaps reduce transparency.

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 and well-structured: a purpose line followed by parameter details in a clear list. Every sentence adds value, and the most critical information appears first.

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 tool's complexity (fuzzy matching with tie-breaking) and the absence of an output schema, the description falls short by not explaining the return value (e.g., matched catalog entry object). It covers input behavior but not output structure, which is essential for an agent to use the result.

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?

With 0% schema description coverage, the description adds significant value by explaining each parameter with examples (e.g., vendor: 'Hatchbox', material_type: 'PLA', color: optional for tie-breaking). However, it does not clarify that all parameters are optional or that at least one may be expected for meaningful matching.

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's purpose: fuzzy-match a catalog entry from spool metadata, matching against vendor and material type as case-insensitive substrings, with optional color tie-breaking. It distinguishes itself by focusing on spool metadata matching, but does not explicitly differentiate from siblings like find_material_substitute.

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 this tool versus alternatives. It does not mention prerequisites, when not to use it, or point to other tools for different scenarios.

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