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

No annotations are provided, so the description carries the behavioral burden. It discloses that the call is fire-and-forget, not shown to the end user, and only records feedback for maintainers. This is important behavioral context. It doesn't mention error handling or rate limits, but for a simple feedback submission that's acceptable. No contradictions with annotations (none exist).

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 paragraph but front-loaded with the primary purpose and exclusions. It provides actionable guidance without excessive length. It's slightly verbose but every sentence contributes meaning. It could be trimmed slightly, but it's well-structured.

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 feedback submission tool with no output schema, it fully explains what happens (fire-and-forget, recorded for maintainers), when to use it, and what to include. There are no hidden behaviors or expectations an agent would need beyond what's described. It's complete for its purpose.

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 100% with descriptions for all six parameters. The description adds value by instructing the agent to be specific and actionable, naming the tool_name, and describing expected vs actual outcomes — which guides how to fill the parameters. This is more than just repeating schema fields, so it earns a 4 above the baseline 3.

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 a specific verb and resource: 'Report feedback about the robot-actions MCP device-control tools THEMSELVES.' It explicitly distinguishes from app-under-test feedback and is unambiguous about its purpose. It's a meta-tool among many device-control siblings, and the description makes that distinction obvious.

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?

It explicitly tells when to use it ('when a tool was confusing, missing a capability you needed, behaved like a bug, or worked well and confirmed something'), and explicitly excludes the app under test. It also gives concrete guidance on what to include (tool_name, situation, expected vs actual). No alternatives are needed since this is a unique feedback channel.

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