insert_hwp_table

Insert a table into an HWPX document by providing headers and row data in JSON format. The table is added at the end of the document body.

Instructions

Insert a real OWPML table at the end of an .hwpx body (proper hp:tbl/hp:tr/hp:tc). headers and rows are both JSON string arrays — headers is a single-row array of strings, rows is an array of row arrays. Args: file_path, headers, rows, output_path (optional).

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Behavior2/5

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 disclosure. It explains the JSON format for headers and rows but omits critical details such as error handling, overwriting behavior, permission requirements, or what happens if the file does not exist. It does not state whether the table is appended to existing content or requires an empty document.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Description is two sentences and front-loads the core purpose. The second sentence is a bit run-on with 'Args:' but conveys necessary parameter info concisely. Could be more scannable with bullet points, but overall efficient.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema and no annotations, the description should cover inputs, behavior, and output. It covers input formats but omits what the tool returns (success indicator, error messages, created table details). Behavior for optional output_path is not described. Missing behavioral constraints for a tool that modifies files.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0% (properties have only type string, no descriptions). The description adds significant meaning by explaining file_path as path to .hwpx file, headers as JSON array of strings (single-row), rows as array of row arrays, and output_path as optional. It clarifies the expected JSON structure for parameters, compensating for the schema's lack of detail.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the action ('Insert'), resource ('real OWPML table at the end of an .hwpx body'), and specifies the structural elements (<hp:tbl>/<hp:tr>/<hp:tc>). This differentiates it from siblings like append_hwp_table_row (which adds rows to existing tables) or insert_hwp_image (different resource).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description does not provide explicit guidance on when to use this tool versus alternatives like append_hwp_table_column or merge_hwp_cells_horizontal. It mentions inserting 'at the end' but lacks direction on prerequisites, conditions for use, or when not to use it.

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