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

No annotations are provided, so the description carries the full burden. It states 'Get' but doesn't clarify if this is a read-only operation, what permissions are required, whether it returns metadata or file content, or if there are rate limits. For a tool with no annotations, this lacks essential behavioral details.

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, efficient sentence with no wasted words. It's front-loaded and appropriately sized for the tool's apparent simplicity, making it easy to parse quickly.

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 annotations, 0% schema coverage, no output schema, and two required parameters, the description is incomplete. It doesn't explain what 'Get' returns, the parameter semantics, or behavioral traits like safety or permissions, leaving significant gaps for an agent to use the tool effectively.

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%, so the schema provides no parameter details. The description mentions 'by its ID' but doesn't explain the two required parameters ('id' and 'backupFileId'), their relationship, or format. It adds minimal value beyond the schema, failing to compensate for the coverage gap.

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 'Get a specific backup file by its ID' clearly states the action (Get) and resource (backup file), but it's somewhat vague about what 'Get' entails (e.g., retrieve metadata, download content). It doesn't differentiate from sibling tools like 'GetBackup' or 'GetAllBackupFiles', which handle related backup operations.

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. The description doesn't mention prerequisites, such as needing a valid backup file ID, or contrast it with siblings like 'GetAllBackupFiles' for listing files or 'DownloadBackupMeta' for downloading metadata. This leaves usage context unclear.

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