drive_read

Read a file from this line's Drive folder. Text and PDF come back as text. Large files return one part and next.

B3/5.0
Behavior3/5

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

With no annotations, the description carries the full load and does disclose useful return behavior: text and PDF are converted to text, and large files are chunked across calls. However, it says nothing about permissions, error conditions, or whether reads are side-effect free.

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

Conciseness4/5

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

Three short sentences, front-loaded with the core action and no filler. The phrasing 'return one part and next' is slightly clipped but still readable.

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?

There is no output schema, so the description does well to describe the return shape (text, PDF-to-text, chunking). Still missing are parameter semantics and any note on failure modes for a three-parameter file-reading tool with zero schema documentation.

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?

Schema description coverage is 0%, so the description must compensate and largely doesn't. 'One part and next' hints at paging via start/limit, but it never explains what file_id means, what units limit uses, or how to request the next chunk.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource ('Read a file from this line's Drive folder'), which clearly separates it from drive_list and drive_put. It stops short of naming a sibling explicitly, but the action is unambiguous.

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

Usage Guidelines2/5

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

It gives no when-to-use or when-not-to-use guidance and never points to drive_list, drive_put, or drive_sync as alternatives. The only scoping cue is the vague phrase 'this line's Drive folder'.

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