memory_snapshot_create

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

Annotations already indicate readOnlyHint=false, destructiveHint=false. Description adds 'backup' implying safe save, but does not disclose if overwriting occurs, performance impact, or any locking. No contradiction with annotations.

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?

Single sentence clearly stating action and resource, front-loaded with 'Create a snapshot'. No wasted words.

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 no output schema and 3 well-described params, the description conveys core purpose. However, for a create tool, it could mention if snapshots are incremental, if they affect current state, or prerequisites (like space existence). Minimal but adequate.

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 coverage is 100% with descriptions for all 3 parameters. The tool description adds no extra meaning; the example in name description is helpful but already in schema. Baseline 3.

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?

Description uses specific verb 'create' and resource 'snapshot (backup) of the current memory state'. It clearly distinguishes from sibling snapshot tools like list, delete, restore.

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?

Implies usage for backing up memory, but no explicit when/when-not guidance or mention of alternatives like memory_export. Sibling tools like memory_export suggest export options, but no comparison is made.

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