split_table_cell

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

No annotations are present, so the description carries the full burden of explaining side effects. It only restates the split action and parameter labels; it does not disclose whether the original cell is replaced, whether cell contents are preserved or distributed, what happens to merged regions, or any constraints on split counts.

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 compact and front-loaded with a one-sentence purpose followed by a clear argument list. There is no redundant prose, though the argument list could be tightened or augmented with constraints without becoming verbose.

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 mutating table operation with six parameters and no annotations, key operational details are missing: 0-based vs 1-based indexing, what happens to existing cell content, whether split_rows or split_cols can be 1, and how the result is returned. The description is minimally usable but not sufficiently complete for confident correct invocation.

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%, and the description compensates by defining all six parameters, including the useful note that doc_id comes from open_document and the meanings of row, col, split_rows, and split_cols. It stops short of specifying index bases, valid ranges, or the consequences of default values, but it adds real meaning beyond the bare schema titles.

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 states a specific action and resource — split a table cell into multiple cells — which is clear and distinct from siblings like merge_table_cells. It does not explicitly name alternative tools, but the verb 'split' and the resource 'table cell' make the core purpose unambiguous.

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?

There is no guidance about when to use this tool versus the closely related merge_table_cells, add_table_column, delete_table_row, or set_table_cell_text. The intended use must be inferred from the tool name and the short description, with no exclusions or alternative routing.

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