pt_update_device

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

The only annotation is openWorldHint=false, so the description carries nearly the full behavioral burden. It implies a mutation but does not state what happens when optional fields are omitted, whether the operation is partial or full replacement, permission requirements, or what the response contains. For a mutating tool with sparse annotations, this is a significant gap.

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 that front-loads the key verbs and resource. It is efficient, though its brevity is partly achieved by omitting necessary detail rather than by careful editing.

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?

This is a five-parameter mutation tool with no output schema and only an openWorldHint annotation. The description does not cover null-default behavior, partial update semantics, or side effects, leaving the agent under-informed about how to call it correctly.

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 0%, so the description must compensate for five undocumented parameters. It loosely maps rename to new_name, move to x/y, and power to the power flag, but does not explain null defaults, coordinate semantics, whether name is the current identifier, or what happens to position when x/y are omitted.

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 gives specific verbs (rename, move, power on/off) and a clear resource (a device), so the agent can tell it modifies an existing device rather than adding or deleting one. It distinguishes reasonably from siblings like pt_add_devices and pt_delete_devices, though it doesn't name alternatives.

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?

There is no guidance on when to use this versus pt_add_devices, pt_delete_devices, or pt_device. No exclusions, prerequisites, or alternative routes are mentioned.

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