hwp_auto_fill_from_reference

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

No annotations are provided, so the description shoulders full responsibility. It mentions '서식 보존 채우기' (format-preserving fill) and '일괄 수행' (batch perform), but does not disclose whether the tool modifies the document in-place, creates a new one, or what happens on failure (e.g., mapping errors, file access issues). For a composite tool, more behavioral context is needed.

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 two sentences and front-loads the key functionality. However, it could be more structured with bullet points or separation of purpose from usage context. Still, it is appropriately sized and clear.

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 composite nature and many sibling tools, the description lacks information on workflow steps, output format, and prerequisites (e.g., file must exist, document must be open). It also does not specify that it likely modifies the current document. With no output schema, more context is needed for complete understanding.

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% and all parameter descriptions are present in the schema. The description adds no additional parameter details beyond the schema, so it meets the baseline without adding extra value.

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 it's a one-stop tool for automatic mapping and format-preserving filling from Excel/CSV, integrating three sub-tools. It provides a concrete example request, and the verb '수행' (perform) combined with '원스톱 도구' (one-stop tool) distinguishes it from sibling tools that are more granular.

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 explicitly mentions it integrates hwp_smart_fill, hwp_read_reference, and hwp_auto_map_reference, implying it should be used when all three are needed. However, it does not explicitly state when NOT to use it or provide alternatives for simpler tasks, leaving some ambiguity.

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