delete_file_content

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

The description discloses that substring deletion only removes the substring within the row, not the entire row. However, with no annotations, it fails to mention destructive nature, error handling, or index behavior (e.g., shifting after deletion).

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 structured with Args and Returns, and each parameter is explained in a single line. It is not overly verbose, though it could omit 'Args:' and 'Returns:' for brevity.

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 destructive tool with no annotations and no output schema, the description omits important details: error cases (e.g., invalid row), behavior when both row and rows are provided, and return value. This leaves significant gaps for an agent.

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 0%, but the description adds full meaning: row is 0-based integer, rows is list, substring optional for partial deletion. This compensates entirely for the missing schema explanations.

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 tool deletes content at specific rows from a file, using a specific verb and resource. It distinguishes from siblings like update_file_content and insert_file_content by focusing on deletion.

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?

No explicit guidance on when to use this tool versus alternatives such as update_file_content or write_file. The description lacks context for choosing between row deletion and substring deletion.

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