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

With no annotations, the description carries full burden. It usefully discloses that the response contains an app-wide key and cipher (sensitive material), but says nothing about whether the call is read-only, what permissions are required to retrieve secrets, or any side effects.

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?

One short sentence fragment with no padding, and the key information (single slug, returns key and cipher) is front-loaded. It is efficient but under-specified rather than genuinely concise.

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 one-parameter tool with an output schema, the description covers the essential idea: it fetches one device entry by slug and includes key/cipher fields. The main missing piece is how to obtain a valid slug and whether secret retrieval needs authorization, which is a moderate gap rather than a fatal one.

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 coverage is 0% for the single parameter, and the description only says "one slug" without explaining the format, case sensitivity, or where a slug comes from (e.g., list_devices output). It adds a hint about the parameter's role but does not compensate for the undocumented schema.

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 phrase "the device library entry for one slug" identifies the resource and scopes it to a single item, which implicitly contrasts with list_devices/classic_devices. However, it is a noun fragment describing the return value rather than stating the action, so the agent must infer the verb from the tool name.

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 guidance on when to call this versus list_devices, classic_devices, or connect. There is no mention of prerequisites (e.g., obtaining a slug first) or exclusions, leaving selection entirely to inference from the name.

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