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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, covering safety. The description adds valuable context beyond annotations: the cost ($2.50 USDC via x402) and the output nature (a report). This helps the agent understand the side effects (payment) and result format, which annotations do not convey.

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, well-structured sentence that front-loads the core action, followed by critical pricing information. Every word earns its place, with no redundant or vague 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?

Given the open schema and lack of output schema, the description covers the essential context: what the tool does, what input to provide (release notes and checks), what output to expect (a report), and the cost. It does not detail report structure or the exact meaning of 'checks', but for a generative tool this is sufficient for an agent to invoke it correctly.

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 is an open object with no defined properties, so schema description coverage is vacuously 100%. The description mentions 'release notes and checks' as expected content, giving some direction. However, it lacks specifics on structure, required keys, or formats. This is adequate but not rich, matching the baseline 3 for high schema coverage.

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 function: 'Turn supplied release notes and checks into a risk-ranked launch readiness report.' It specifies the action (turn into), the input (release notes and checks), and the output (risk-ranked report). This distinguishes it from siblings like agent-endpoint-readiness by focusing on launch readiness with risk ranking.

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 context is implied: the tool is appropriate when you have release notes and checks to evaluate. However, it does not explicitly state when to use this tool versus alternatives, nor does it provide exclusions or mention alternative tools. This is minimal viable guidance.

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