Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint and idempotentHint, and the description adds topical context (free request validation, recipes, limits, paid MCP path) that clarifies what the tool exposes. It does not contradict annotations, though it does not detail additional behavior like return format or whether any computation occurs.
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 a single sentence, front-loaded with the verb 'Describe' and efficiently lists all covered topics in a comma-separated list. There is no wasted verbiage or repetition.
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 informational tool with no output schema, the description adequately covers the essential context: when verification is or isn't useful, validation, recipes, limits, and the premium paid path. The sibling tools provide operational context, and this description stands alone as 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 input schema has zero parameters, so a baseline of 4 applies. The description does not need to explain parameters since none exist, and no additional semantics are missing.
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 uses the specific verb 'describe' and clearly identifies the resource: the Agent Verification Utility. It enumerates distinct facets (usefulness, non-usefulness, validation, recipes, limits, paid MCP path), distinguishing it from operational siblings like verify_evidence and commercial ones like quote_verify_evidence.
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 implies its use for learning about deterministic verification, but it does not explicitly state when to choose it over the sibling tools (e.g., 'use verify_evidence to verify, use this tool for guidance'). No exclusions or alternative tool recommendations are given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

The tools mostly have distinct purposes, but there is overlap between quote_verify_evidence and prepare_verify_evidence_purchase, both involving quotes, and describe_verify_evidence also mentions validation. This could cause some confusion for agents deciding which tool to call.
All tool names follow a verb_noun pattern in snake_case, which is consistent. The only minor deviation is get_revenue_goal_status, which is longer but still verb_noun. Overall, the naming is predictable.
Five tools is well-scoped for a verification utility with a payment flow. Each tool serves a distinct step in the workflow without unnecessary bloat.
The tool set covers the full lifecycle from description and status checks through quoting, purchase preparation, and final verification. No obvious gaps exist for the stated purpose.
