ping

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

No annotations provided. Description only hints at 'report analysis status' without detailing behavior, side effects, or output. For a ping tool, more context on what 'analysis status' means would help.

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?

Single sentence is concise and front-loaded, but could be slightly more structured to mention output. Still efficient.

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?

Tool is simple with one param and output schema exists (but not shown). Description missing explanation of what 'analysis status' entails, which could be important for usage.

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?

Parameter 'message' already well-described in schema ('Message to echo'). Description adds no new meaning beyond schema, so baseline 3 is appropriate.

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 echoes a message and reports analysis status, which is a specific verb+resource. It distinguishes from unrelated 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?

No explicit guidance on when to use or alternatives, but the simplicity and distinct purpose make it adequate. Sibling tools are all different, so minimal confusion.

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