  2. First observedv0.1.0

TDQS

A4.4/5.0
Behavior5/5

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

Discloses two meaningful behaviors beyond the annotations: it auto-creates local parent directories assuredly, and it refuses to overwrite existing files unless overwrite:true is set. This materially helps the agent anticipate side effects beyond the raw destructiveHint.

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?

Two concise, front-loaded sentences cover the primary action and both edge-case behaviors. No redundancy with the title or the input schema.

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

Completeness4/5

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

For a simple download tool with a rich input schema and output schema, this is mostly complete. It could mention what happens on remote-file absence or connection failures, but those are minor gaps given the structured context.

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

Parameters4/5

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

The schema already covers all parameter descriptions (100%), giving a baseline of 3. The description adds relevant semantics by clarifying that local parent directories will be created and that overwrite is disabled by default, which supplements the parameter meaning.

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?

States a specific verb ('download'), the source ('remote file'), the destination ('local path'), and two behavioral constraints (auto-creating parent directories, refusing to overwrite unless asked). This clearly identifies the tool's job and distinguishes it from siblings like ftp_read or ftp_upload.

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 phrase 'download a remote file to a local path' gives clear operational context for when this tool would be used. However, it does not explicitly contrast it with alternatives such as ftp_read (view without saving) or mention any selection criteria, so the guidance is mostly implicit.

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