Confirm QGIS is responsive and report its version, ensuring the connection works before map generation or export.
Check that QGIS answers and report its version.
This tool declares no required parameters. Add optional parameters from the input schema as needed.

v0.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries the burden, but for a zero-parameter probe the risk surface is minimal. It discloses that it reports a version, implying a safe read, but does not state what happens on failure or the exact response shape.
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 front-loaded sentence with zero waste, stating both the action and the expected output.
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 trivial connectivity probe with no params and no output schema, the description says enough: it checks liveness and returns version info. Minor gaps around failure behavior, but nothing essential 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 takes zero parameters, so the baseline is 4. There is nothing to document and the description correctly implies a no-argument call.
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 gives a specific verb+resource ('Check that QGIS answers') plus a return hint ('report its version'), which is more than a tautology. It doesn't differentiate itself from siblings, though the uniqueness of the name makes confusion unlikely.
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 implied: this is a connectivity/health-check tool to confirm QGIS is responsive before other operations. No explicit when-to-use, when-not-to-use, or named alternatives are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
