create_file_snapshot

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

The description mentions 'direct file copying' which implies the original file is preserved, and notes speed as a benefit. However, without annotations, it fails to disclose other behavioral aspects such as permissions, storage location, overwrite behavior, or error conditions, leaving ambiguity about the snapshot's side effects.

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 two concise sentences that immediately state the purpose and a distinguishing advantage. Every word adds value, with no redundancy or irrelevant detail.

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?

Although the schema covers all parameters, the description omits critical information about return values (e.g., snapshot ID), storage of snapshots, error handling, and integration with sibling tools like restore_file_snapshot. Without annotations or an output schema, this leaves the tool incompletely specified for an AI agent.

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 are fully described in the schema (100% coverage), including prompt, filePath, metadata, and sessionId. The description adds no additional parameter-specific meaning beyond what the schema already provides, so the baseline score of 3 is appropriate.

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 tool creates a file snapshot for backup and restore, and explicitly distinguishes it from record_edit by noting it's faster and uses direct file copying. This specific verb and resource combination makes the purpose unambiguous.

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 a clear context by comparing to record_edit, indicating this tool is a faster alternative for creating backups. However, it does not explicitly mention when not to use it or enumerate other alternatives like restore_file_snapshot, so it stops short of full exclusion guidance.

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