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

Annotations already indicate non-read-only and non-idempotent behavior, and the description adds useful context: the tool costs $0.15 and requires an API key. It also outlines the internal process (Hive scans, Groq synthesizes), giving transparency beyond the annotations.

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?

The description is compact and front-loaded: it states the action, the process, the benefit, the cost, and the requirement in three sentences. Every sentence adds value with no redundancy or filler.

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?

With two parameters (one required), no output schema, and existing annotations, the description covers the essential context: what the tool does, how it works, the cost, and the API key requirement. It could elaborate on the exact return format, but the description is adequate for a text-in/text-out tool of this complexity.

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 input schema covers 100% of parameters with descriptions. The tool description adds marginal meaning by elaborating on the 'performance issue' concept (failure log) and mentioning the optional agent_type example, but it does not deeply augment parameter semantics beyond the 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?

The description clearly states the tool's purpose: submit a performance issue/failure log and receive an evolved execution plan. It uses specific verbs ('Submit', 'scans', 'synthesizes') and distinguishes itself from siblings by focusing on agent evolution rather than acting, seeing, or reputation.

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 description provides clear context on when to use the tool: when you have a performance issue or failure log and want an optimized plan for that failure mode. It does not explicitly mention alternatives or exclusions, but the use case is well-defined.

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