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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds the content areas and the once-per-conversation usage pattern, but does not describe the response structure or any additional behavioral caveats. With strong annotation coverage, this is adequate but not rich.

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 short sentences with no waste. The content areas are listed first and the usage directive follows immediately, making the definition front-loaded and easy to scan.

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, read-only capability tool, the description covers what the tool returns and when to call it. The absence of an output schema means the description could say more about response shape, but the listed content areas are sufficient for an agent to invoke it correctly.

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 there is no parameter semantics to explain. Baseline for zero-parameter tools is 4, and nothing in the description creates confusion 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?

The description names the specific content the tool returns: workflows, languages, inputs, outputs, lifecycle states, and limits. Combined with the tool name get_capabilities, an agent can understand this is a capability-reference tool rather than a production action. It does not explicitly distinguish itself from every sibling, but the meta nature is clear.

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 gives a clear usage directive: 'Call once per conversation to ground your advice.' This tells the agent both when to call it and how frequently. It does not name alternatives, but the intended role is obvious among production-oriented siblings.

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