colab_download

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

No annotations are provided, so the description carries the full behavioral burden. It states the transfer direction (VM to local working directory) but omits session requirements, overwrite/exists behavior on the destination, failure modes, and any rate or size limits for a file-transfer mutation.

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?

A single front-loaded sentence with no filler. It is efficient, though arguably too sparse for a tool with a required remote/local path pair and an unlabeled session parameter.

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?

An output schema exists, so return-value explanation is not required. However, with no annotations, 0% parameter coverage, and no usage routing, the definition leaves key invocation details (session selection, overwrite behavior, destination semantics) unstated.

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 0% across three parameters. The description only loosely implies remote_path (the VM file) and local_path (local destination) and says nothing about the optional session parameter, so it does not compensate for the empty schema.

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?

States a specific verb (Download) and resource (one file from the VM into the working directory). The word 'one' implicitly distinguishes it from the colab_download_dir sibling, though it does not name that alternative explicitly.

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?

Usage is only implied: the singular 'one file' hints at when to prefer this over colab_download_dir, but there is no explicit when-to-use, when-not-to-use, or named alternative. An agent must infer the routing from the sibling name alone.

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