nexo_closure_snapshot

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

With no annotations, the description must disclose behavioral traits. It mentions 'write and return' but does not explain side effects (e.g., whether previous snapshots are overwritten), authentication requirements, rate limits, or what 'Operational Closure Plane' entails. This lack of detail significantly limits transparency.

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 short sentence that is concise and not verbose. However, it could be more informative without sacrificing brevity, earning a middle score.

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 lack of output schema and parameter descriptions, the description is too brief to be complete. It does not explain what a snapshot contains, how it is used, or how the tool fits into the broader workflow. More detail is needed for effective use.

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 input schema has 3 parameters (refresh, snapshot_date, limit) with defaults but no descriptions. The description provides no additional meaning, leaving the agent to infer their purpose from names alone. This is insufficient for correct invocation.

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 'Write and return an Operational Closure Plane daily snapshot' clearly states the action (write and return) and the resource (daily snapshot), and it distinguishes from sibling tools like nexo_closure_close or nexo_closure_status by focusing on snapshot creation. However, it does not explicitly differentiate from other snapshot tools like nexo_continuity_snapshot_write, so it is not a 5.

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 provided on when to use this tool versus alternatives. There is no mention of prerequisites, context, or situations where it should not be used. The description only states the function without any usage context.

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