Create snapshot

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

The description 'Create a file manifest snapshot' implies a write operation, but annotations mark readOnlyHint as true, indicating a read operation. This is a direct contradiction, making the description misleading. No additional behavioral traits are disclosed.

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 concise (one sentence) but lacks critical detail. It is not overly verbose, yet it sacrifices informativeness for brevity.

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 parameter descriptions, an existing output schema, and a misleading annotation/description mismatch, the description is incomplete. It does not adequately prepare an agent to use the tool correctly.

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%, and the description does not explain the purpose or format of either parameter (workspaceId, reason). It only mentions 'open workspace' implicitly, which is insufficient for understanding parameter usage.

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 (Create) and resource (file manifest snapshot), along with the context (for an open workspace). It is specific enough to distinguish from general tools, but does not explicitly differentiate from sibling 'checkpoint_create', which could be similar.

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 like checkpoint_create or other snapshot-related tools. The description lacks any 'when to use' or 'when not to use' information.

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