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

No annotations are provided, so the description bears the behavioral burden. It usefully discloses that the log returns ids, times, and reasons but never content, and that a prepare step is required. It does not state authentication requirements beyond the signature fields, rate limits, or whether results are paginated.

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 front-loaded with the tool's purpose and the prepare prerequisite, then lists args compactly. The four argument lines are brief and earn their place, though a little more format detail could be useful without bloating.

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 4 required parameters, 0% schema description coverage, and an output schema that documents returns, the description covers the essential prepare flow and audit-log contents. It omits error behavior, retry semantics, and how to handle an expired nonce or timestamp, which are relevant for a security-sensitive signed call.

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?

Schema description coverage is 0%, so the description must compensate. It explains that wallet is the agent's 0x wallet address, and that timestamp, nonce, and signature come from memory_prepare. It does not clarify formats, single-use enforcement beyond nonce, or signature message scope, leaving some ambiguity.

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?

States a specific verb+resource: it is a deletion audit log returning ids, times, and reasons but never content. This distinguishes it from siblings like memory_history and memory_delete. The scope is clear, though it does not explicitly name which sibling to prefer for related queries.

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?

Explicitly instructs the agent to call memory_prepare with operation "deletions" first, which is a concrete usage prerequisite. It does not, however, describe when to use this log versus memory_history or memory_search, so alternatives are not exhausted.

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