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

With no annotations provided, the description carries the full burden of behavioral disclosure. It adequately describes the core functionality (returns all possible base forms and word classes) and output structure, but lacks details on error handling, rate limits, authentication needs, or performance characteristics that would be helpful for an agent.

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 efficiently structured with a clear purpose statement, parameter documentation, and return value explanation in just three sentences. Every sentence adds essential information with zero wasted words, making it easy to parse.

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 single-parameter tool with no annotations and no output schema, the description provides good coverage of purpose, parameters, and return structure. However, it lacks explicit error cases or limitations (e.g., handling of non-Icelandic words, empty inputs), which would make it fully complete for agent use.

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 schema description coverage is 0%, so the description must fully compensate. It explicitly documents the single parameter 'word' with clear semantics ('The word form to analyze'), provides examples, and explains what it represents (inflected Icelandic form), adding significant value beyond the bare schema.

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 specific verb ('find') and resource ('lemma(s) and word class(es)'), explicitly distinguishes from siblings by focusing on Icelandic word form analysis, and provides concrete examples ('hestana', 'laga', 'færi') to illustrate its unique function.

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 clear context ('Given any inflected form') and implies usage for Icelandic language analysis, but does not explicitly state when to use this tool versus the sibling tools (get_variant, lookup_word), nor does it mention any exclusions or prerequisites.

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