touchlink_identify

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

With no annotations provided, the description must carry behavioral disclosure. It does state the observable effect (the device blinks), but it does not mention whether the command is safe, whether the device must be in physical proximity, what failures may occur, or what the output represents beyond the schema.

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?

The description is compact and front-loaded: one clear sentence explains the tool's action, followed by a minimal parameter note. Every word earns its place with no repetition of the schema.

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?

The tool is simple, has a single required parameter, and has an output schema, so the description does not need to explain return values. The missing guidance about when to use touchlink_identify versus touchlink_reset or scan is a minor gap, but overall the description is adequate for a focused 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 schema has 0% parameter description coverage, but the description compensates by explaining that touchlink_id is the 'Device ID from get_touchlink_results.' This gives useful provenance for the parameter even though it does not describe the exact format or constraints of the ID.

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 clearly states the action and resource: 'Make a Touchlink device blink to identify itself.' This distinguishes it from the other touchlink sibling tools (scan, reset, get_results) by its observable outcome, though it does not explicitly contrast itself with those siblings.

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?

The description implies usage context by specifying that touchlink_id should come from get_touchlink_results, indicating this runs after a scan/results step. However, it does not explicitly say when to use this tool versus the other touchlink operations or provide exclusions.

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