get_device_config

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

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is fully covered. The description adds only that versions were 'collected for a device instance', which is mildly informative but doesn't disclose ordering, pagination behavior, or error semantics. No contradiction; it just adds minimal value beyond annotations.

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 eight-word sentence with no filler. The core verb, resource, and scope are front-loaded, and every word earns its place.

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 simple list tool with a well-documented schema and strong safety annotations, the minimal description is adequate. However, with no output schema, the description doesn't clarify what fields a config version contains, what ordering is applied, or how limit/offset affect results beyond the schema defaults. These gaps are non-fatal but make it only minimally complete.

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 100%, so the schema already documents all five parameters. The description doesn't add any parameter-level meaning beyond what the schema provides, matching the baseline of 3.

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 uses a specific verb (List) and resource (config versions) with a scoping qualifier (collected for a device instance). It clearly identifies the operation, though it doesn't explicitly differentiate from the sibling get_device_config_version; the plural 'versions' implies a list operation but leaves the distinction implicit.

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 explicit guidance is given about when to use this tool versus alternatives like get_device_config_version (singular fetch) or collect_device_config (trigger collection). The only hint is the word 'List', which implies a query operation, but no exclusions or alternative-selection criteria are stated.

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