Restore XMemo memory

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

The description indicates the tool restores a previously deleted memory, which is a behavioral trait. Annotations already declare destructiveHint=false, and the description adds context about user intent. However, it does not detail what happens to the restored memory (e.g., ID reuse, content restoration) or any permissions needed.

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 extremely concise: two sentences with no unnecessary words. It front-loads the purpose and usage condition.

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 tool's complexity (3 parameters, annotations present, output schema exists), the description adequately covers the core purpose and usage context. The output schema handles return value details, so no further elaboration is needed.

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?

All parameters have descriptions in the schema (100% coverage). The description adds the phrase 'shown by search or recall' for memory_id, which is helpful. For 'reason' and 'metadata_json', descriptions are generic, so the added value is marginal.

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 action ('Restore') and the resource ('a previously deleted memory'). It distinguishes from sibling tools like 'forget' and 'remember' by specifying the restore operation.

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 provides explicit guidance: 'Call this only when the user explicitly asks to restore or undo a deletion.' This clearly indicates when to use the tool, though it does not explicitly mention alternatives or when not to use it.

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