figure_library_network_test

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the agent knows this is a safe outbound read. The description adds useful context that the test is 'bounded' and hits a fixed endpoint (no arbitrary target), but it doesn't disclose timeouts, failure modes, or whether it mutates server state.

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 sentence with zero waste; the scope-limiting detail ('only against the fixed SFL GitHub releases endpoint') is front-loaded.

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 zero-parameter, annotation-covered utility, the description gives enough to call it correctly. It could add what a successful/failed test returns, but with no output schema that is a minor omission rather than a blocker.

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 no parameters, so the baseline is 4. The description correctly implies nothing is configurable — the endpoint is fixed — which is consistent with the empty 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?

States a specific verb+resource: running a bounded connectivity test against the fixed SFL GitHub releases endpoint. This is more specific than the sibling 'network_status' by making clear it's a test of one fixed endpoint, though it doesn't explicitly name the differences from that sibling.

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?

The 'only against the fixed... endpoint' phrasing implies usage is narrowly scoped and non-configurable, but there is no explicit when-to-use versus 'figure_library_network_status' or other status tools. The guidance is implied rather than stated.

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