jactus_get_version_info

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

No annotations provided, but the description fully carries the burden by stating it returns version info, implying a safe read operation. It could add more context (e.g., speed, availability), but it is sufficient for a simple version query.

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 that immediately state the purpose and list the returned information. No wasted words.

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 parameterless tool with an output schema, the description fully covers the purpose and return content. No gaps remain.

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?

No parameters exist in the input schema, so the description does not need to add parameter meaning. Baseline 4 is appropriate given zero params.

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 retrieves version information for JACTUS and MCP server, plus Python version and compatibility. This is a specific verb+resource that distinguishes it from all sibling tools, which focus on contracts, risk, simulations, etc.

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 is obvious when to use this tool (to get version info). There are no alternatives or exclusion reasons needed since this is a unique purpose among siblings, but it does not explicitly state when not to use it.

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