overleaf_download_file

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

With no annotations, the description carries the burden of behavioral disclosure. It states the tool downloads exactly one file and returns its local path, which covers the key outcome and side effect. It does not mention prerequisites like authentication or whether it overwrites existing local files, but for a read-like file download this is reasonably transparent.

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?

Two sentences with no filler. The primary purpose is front-loaded, and the second sentence provides a concise workflow. Every clause earns its place.

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 two-parameter tool with no output schema, the description is complete: it states what the tool does, where the file goes, what it returns (the path), and how to integrate it with upload for modifications. Nothing essential for a basic call is missing.

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 description coverage is 100%, so the baseline is 3. The description adds minor context by tying project_id to the target directory and emphasizing that exactly one file is downloaded, but does not substantially enhance the parameter semantics beyond the schema's own descriptions.

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 opens with a specific verb and resource: 'download exactly one Overleaf file' and clarifies its file-reading role, distinguishing it from siblings like overleaf_download_pdf and overleaf_upload_file. The scope is precise, including the underlying directory structure under OVERLEAF_DATA_DIR.

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?

It explicitly provides a workflow for modification: download, edit, then call overleaf_upload_file with overwrite: true. This clearly tells agents when and how to use the tool in a common scenario. It does not mention exclusions versus sibling tools such as overleaf_download_pdf, but the file-reading vs PDF distinction is strongly implied.

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