Test Tool

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

No annotations are provided, so the description carries the full behavioral burden. It does not say whether the call is read-only, what happens to the supplied message, whether it logs or echoes, or what a success/failure result looks like — all relevant for even a trivial test endpoint.

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?

A single short sentence, front-loaded with the purpose and free of waste. It is not a 5 because at this length the sentence has no room for a qualifying clause that would add real value.

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 structurally simple (one required string, no nesting, no output schema), so the description is close to sufficient. The remaining gap is behavioral: with no annotations and no stated result semantics, an agent still cannot predict what the call does beyond 'it's a test'.

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?

There is a single parameter with 100% schema description coverage ('Test message'), so the schema already documents it. The description adds nothing about the message's role (echoed back, ignored, logged), which is the baseline-3 outcome for a fully covered schema.

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 purpose — verifying MCP integration — which goes slightly beyond the name 'Test Tool', so an agent understands it is a smoke-test/connectivity check. However, 'test tool' is a weak verb+resource pairing and nothing distinguishes it from the many other mcp_m7_* siblings, none of which is named as an alternative.

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?

Usage is only implied: the phrase 'to verify MCP integration' suggests calling it as a setup/sanity check. There is no explicit when-to-use, when-not-to-use, or comparison against sibling tools such as mcp_m7_validate or mcp_m7_doctor, which could plausibly be confused with a verification step.

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