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

The description adds deterministic behavior and paid-resource cost information beyond the annotations, which already establish read-only, non-destructive, idempotent behavior. It does not contradict the annotations and gives additional practical context about invocation cost.

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 three short sentences with no filler. It front-loads the core behavior, then adds intended-use and exclusion guidance, then cost. Each sentence contributes distinct useful information.

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 tool with no output schema and no parameter descriptions, the description leaves gaps: the meaning of verification rules, path syntax, tolerance behavior, and the exact result shape are underspecified. It is adequate for basic selection but not fully sufficient for confident invocation of all optional parameters.

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?

With 0% schema description coverage, the description carries more weight. It clarifies the roles of expected and observed values and gestures at 'caller-supplied verification rules,' but it does not explain the semantics of ignore_paths, required_paths, or numeric_tolerance. This is partial compensation, not full.

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 states a specific action—deterministically comparing expected and observed values and reporting material differences—and names the intended domain (reliability quality / vendor lock-in). It does not explicitly differentiate from sibling tools like reliability_quality_verification_dfe703fe by name, though the domain and exclusion list help narrow intent.

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 gives clear when-to-use context ('Intended for reliability quality / vendor lock in') and an explicit when-not-to-use list (legal, identity, sanctions, fraud, contractual, regulatory adjudication). It does not name alternative tools to use for those excluded cases, so it stops short of full routing guidance.

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