hwp_smart_fill

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

Description discloses automatic detection and preservation of font, size, letter spacing, and character width, and that format info is returned. However, it does not explicitly state that existing cell content is overwritten, though 'fill' implies replacement. With no annotations, this is a minor gap.

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?

Three efficient sentences: purpose, contrast, usage guidance, and return info. Front-loaded and free of redundancy.

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?

Covers key differentiator and return value, but lacks details on output format structure and error handling. For a tool with no output schema, slightly more detail on returned format info would be beneficial.

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 parameters are already documented. Description does not add new semantics beyond the context of format detection, which is already implied. Baseline 3 is appropriate.

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?

Description clearly states it fills table cells with automatic format detection and preservation, and explicitly distinguishes itself from hwp_fill_table_cells by highlighting the format handling.

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?

Explicitly says to use this tool when formatting is important (like public institution documents), implying the alternative hwp_fill_table_cells for cases where format preservation is not needed.

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