dmm_read

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

With no annotations, the description carries the full behavioral burden. It usefully discloses that the tool triggers the instrument and then reads a new measurement. However, it does not mention whether the call blocks until the measurement is stable, what happens on trigger failure, or any other 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?

The description is a single concise sentence with a useful parenthetical clarification. There is no wasted text, though it is brief enough that some usage and behavior details are left out.

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 description is adequate for a zero-parameter tool with an output schema. However, the presence of siblings such as dmm_measure, dmm_fetch, and dmm_trigger means an agent could still struggle to select the correct tool without explicit routing or differentiation.

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 has zero parameters, so the schema already fully covers parameter semantics. The description does not need to add parameter details, and the no-parameter baseline of 4 applies.

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 states a specific action and resource: 'Take a new measurement reading from the multimeter', and clarifies that it 'triggers and reads'. It is clear about what the tool does, but does not explicitly distinguish it from closely related siblings like dmm_measure or dmm_fetch.

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 parenthetical 'triggers and reads' implies when this tool should be used: when a fresh, triggered reading is needed. However, there is no explicit guidance about alternatives or when not to use it, which matters given the many similar DMM sibling tools.

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