Write a text file

overleaf_write_file

Create or overwrite text files in Overleaf projects. Missing parent folders are created automatically, enabling direct file management.

Instructions

Create or overwrite a text file in the project. Missing parent folders are created.

Behavior4/5

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

With no annotations provided, the description carries the burden of behavioral disclosure. It explicitly mentions 'overwrite' and that missing parent folders are created, which are the key behavioral facets. It doesn't discuss permissions, return values, or content restrictions, but the most critical behaviors are disclosed.

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

Conciseness5/5

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

The description is two sentences with no wasted words: it states the core purpose and a key additional detail. The information is front-loaded and easy to parse.

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

Completeness3/5

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

For a simple write tool, the description covers the primary operations adequately. However, it does not explicitly distinguish itself from sibling tools, does not mention project context/current project selection, and relies on the agent to infer content semantics and behavior with insufficient detail. These gaps reduce completeness.

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

Parameters2/5

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

The input schema has zero description coverage. The description adds a small amount of semantic for filePath by noting that missing parent folders are created, but it does not clarify content (beyond being a text string) or the role of projectId. Complete coverage for parameters is required because the description is the only source, and it is insufficient.

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?

The description clearly states the action: 'Create or overwrite a text file in the project.' This is a specific verb-plus-resource with scope, and it distinguishes itself from siblings like overleaf_edit_file (targeted edits) and overleaf_upload_file (file uploads) by focusing on full-file text writes.

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

Usage Guidelines3/5

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

The description implies its usage by describing create/overwrite semantics and automatic creation of parent folders, but it does not explicitly say when to use this tool instead of alternatives such as edit_file or upload_file. Usage context is present but not overt.

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