device_info

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

With no annotations at all, the description bears the full behavioral burden and delivers very little: it does not confirm this is a safe, side-effect-free read, nor does it state whether results are cached, per-session, or what the response contains. "Describe" hints at a read but nothing is disclosed explicitly.

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 short, front-loaded clause with no filler or repetition. Its brevity is not the problem — the missing content is, which contextual completeness captures.

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 zero-parameter tool with no annotations and no output schema, the description is the only place to explain what information comes back and when to reach for it. It says nothing about return contents (hardware, OS, workspace path, connectivity) or read-only safety, leaving real gaps for an agent deciding whether to call it.

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?

The tool takes zero parameters and the schema is empty, so there is no parameter meaning to add; the baseline of 4 applies. The description correctly implies no input is required.

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?

"Describe" plus the resource "connected local computer and workspace" signals an informational read about the device/environment rather than a file operation, which does separate it loosely from the file-centric siblings. But "describe" is vague about what is actually produced (OS/arch? paths? workspace root?), so an agent cannot tell concretely what this returns.

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?

No when-to-use guidance, no stated trigger, and no mention of how it relates to siblings such as run_workspace_command or file_info. The agent must guess that this is the tool for learning about the execution environment.

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