Workspace

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

No annotations are provided, so the description carries the full burden. It does disclose one meaningful behavioral trait — the workspace and its contents are 'created and seeded if missing,' implying a side effect on first access — but says nothing about permissions, what the seeded contents are, or idempotency.

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 short sentences with no filler, and the key resource-location fact is front-loaded. Slightly telegraphic but appropriately sized for a simple tool.

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 values need not be explained. Still, with no annotations and an ambiguous action, the description leaves the agent unsure what calling the tool actually does — a notable gap for even a zero-parameter tool.

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, so the baseline of 4 applies; there is nothing for the description to disambiguate.

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 identifies the resource ('where devices.yaml, maps/ and routines/ live') but never states the tool's action or verb — an agent cannot tell whether invoking it returns a path, performs setup, or both. It is not pure tautology (it adds file-location detail beyond the name/title), but the purpose remains vague.

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?

'Edit devices.yaml there' is an implied usage directive, giving the agent some sense of what to do with the workspace. However, there is no explicit when-to-use-vs-alternatives guidance relative to siblings like devices, list_maps, or list_routines.

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