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

With no annotations, description carries burden. Discloses cost and data returned, implying read-only behavior. Does not mention authentication or rate limits, but for a simple parameterless tool, transparency is adequate.

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?

Single sentence, no waste. Front-loaded with action and resource. Every word earns its place.

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?

Tool is simple with no parameters. Description covers purpose, data returned, and cost. Missing details on per-chain behavior (since no chain parameter) and response structure. Without output schema, description partially addresses return values.

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?

No parameters exist, schema coverage is 100%. Description adds no parameter info, baseline for zero parameters is 4.

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?

Clearly states the action 'Get', the resource 'SequenceMiner model health and training stats per chain', and specific data returned (sequence count and last retrain time). Cost information adds clarity. Distinguishes from siblings through unique resource focus.

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?

Provides cost as usage guidance but no explicit when-to-use or alternatives. Siblings are listed but not differentiated. Lack of exclusions limits guidance.

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