Back up memory store

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

The annotations provide readOnlyHint=false and destructiveHint=false, indicating a non-destructive write operation. The description adds the 'point-in-time' aspect, implying a snapshot-like behavior that doesn't modify the source. However, it does not disclose potential side effects like overwriting existing files, permission requirements, or what happens to the destination if it already exists. Given annotations already cover the basic safety profile, the added context is moderate.

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, focused sentence that front-loads the core action and resource. It contains no fluff and is highly efficient, achieving maximum conciseness without sacrificing clarity.

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?

For a tool with one parameter and no output schema, the description is notably incomplete. It does not explain the purpose of the destination parameter, what the tool returns (if anything), or any prerequisites like existing directory structure or permissions. The agent lacks enough information to call it correctly without additional inference or experimentation.

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 schema has zero description coverage for the only parameter 'destination', and the description does not mention this parameter at all. With a single parameter, this is a critical gap. The agent has no information about the expected format, whether it should be a file path or directory, or if it is required (though it's optional in the schema). The description fails to compensate for the missing schema descriptions.

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 verb 'Create' and the resource 'canonical local JSONL store', and adds the qualifier 'point-in-time copy', which distinguishes it from a generic copy. However, it does not explicitly differentiate from sibling tools like export_memory or get_memory_snapshot, leaving some ambiguity about the exact scope.

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?

There is no guidance on when to use this tool versus alternatives such as export_memory or get_memory_snapshot. The description only states what it does, not when it is the preferred choice or what conditions would make it inappropriate. This leaves the agent without selection criteria.

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