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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, but the description adds no behavioral context on top of them. It does not explain the forensic process, the payment gating visible in paymentProof, or any operational caveats. No contradiction exists, but the description is transparent only in a vacuous sense.

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?

Three words is under-specification rather than concise effectiveness. There is ample room to add a verb and critical usage context without bloat, so the brevity does not earn credit.

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?

Even with an output schema and fully described schema parameters, the description is far too thin for a complex, payment-related forensic tool. It doesn't explain what to provide in the memory dump, that a missing paymentProof yields a 402 quote, or what an autopsy result looks like. The structured fields prevent a score of 1, but the overall context is still inadequate.

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 description itself says nothing about memoryDump or paymentProof. However, schema description coverage is 100%, so the baseline is 3 despite the absence of parameter detail in the description.

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, 'Forensic breach autopsy', is a near-synonym of the title 'Post-Hack Autopsy' and the tool name 'hack_autopsy'. It lacks a verb and concrete action/resource detail, and does nothing to distinguish this tool from security.exploit_research or security.audit_agent_code.

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?

No guidance is given on when to use this tool versus alternatives, what prerequisites exist, or when a sibling should be preferred. There is also no mention of the paymentProof/402-quote flow, leaving selection entirely to inference.

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