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

The readOnlyHint=true annotation already establishes this is a safe, side-effect-free read, so the description's added detail about what gets reported (version, standards, commands, integrations) is modest incremental value. It does not mention any cost, auth requirement, or whether the payload is large/static, but for a zero-param read-only call that is acceptable.

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 no filler, and the enumeration of reported content is packed efficiently into the verb phrase.

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-param, read-only, no-output-schema tool, the description names the categories of information returned, which is what the agent needs to decide to call it. It could be slightly stronger by stating this is the entry-point call, but it is essentially complete.

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 there are no parameter semantics to explain; the baseline for a parameterless tool is 4. Nothing in the description misleads about inputs.

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 (Report) and enumerates the resources returned: tool version, supported standards, commands, and available integrations. An agent can tell this is a self-descriptive introspection tool, though it never contrasts itself with potentially overlapping siblings like inspect or blackbox.

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?

There is no guidance on when to call this versus the sibling introspection tools (inspect, blackbox), and no prerequisites or exclusions are stated. The agent must infer that this is a discovery/version call.

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