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

With no annotations, the description carries the full burden of behavioral disclosure. It reveals that the tool is an independent QA notary and produces a signed pass/fail, but it omits critical details such as what 'signed' entails, whether it is read-only or writes a record, permission requirements, and what happens on failure.

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, front-loaded sentence that clearly states the tool's purpose without waste. It is appropriately concise, though the terse phrasing leaves room for additional essential details that would not violate conciseness.

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?

Given no output schema and no annotations, the description should explain the return format and how the deliverable is supplied. It fails to do so, leaving an agent without enough information to invoke the tool correctly and interpret its result beyond the high-level notion of a signed pass/fail.

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 has zero parameters, and the schema description coverage is 100% (vacuously). The description adds no parameter information, which is acceptable given the absence of parameters; however, it does not explain how the deliverable to be checked is provided, which may be a hidden input gap.

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 verb (quality-check), resource (ANOTHER agent's deliverable), and outcome (issue a signed pass/fail), making the tool's function immediately understandable. It does not explicitly differentiate itself from siblings like notarize or honesty_audit, so sibling differentiation is left to inference.

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?

Usage is implied: the tool is for independently QA-ing another agent's deliverable. However, there is no explicit guidance on when to use this tool over alternatives, no exclusions, and no mention of prerequisites or context in which it is appropriate.

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