Ping REAPER

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

No annotations are provided, so the description carries the burden. It discloses that the tool checks connectivity and returns the version, implying a non-destructive read-only operation. While it doesn't explicitly state 'no side effects', the nature of a ping makes this obvious and the description is honest about its outputs.

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?

Two sentences, no wasted words. The core purpose ('check that the bridge is alive') is front-loaded, followed by the return value and usage directive. Ideal brevity for a trivial tool.

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 zero-parameter health check, the description is fully sufficient: it states the operation, the return value, and the recommended ordering relative to other tools. Nothing an agent needs to invoke it correctly is missing.

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 according to the rubric the baseline is 4. There is nothing for the description to add beyond what the schema already implies (an empty parameter set).

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 tool checks that the REAPER bridge is alive and returns the version. It uses a specific verb ('check') and resource ('REAPER bridge'), distinguishing it from the other REAPER tools which perform state changes or queries.

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?

Explicitly states 'Call this first to confirm the connection', providing clear when-to-use guidance. It doesn't mention when not to use it, but for a health check this is self-evident and not necessary.

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