get_backup_history

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

Annotation Contradiction: Description uses 'Get' implying read-only operation, but annotations mark destructiveHint=true without any warning about side effects or destructive behavior in the text.

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?

Appropriately concise, front-loaded with action verb, and parenthetically lists return fields efficiently.

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?

Compensates for missing output schema by listing return fields, but fails to address the destructive annotation or explain what 'last backup' means versus current status.

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?

With 100% schema description coverage, meets baseline; description implies the snapshot parameter by mentioning 'specific Duplicacy snapshot' but adds no additional semantic context beyond schema.

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?

Clearly states it retrieves last backup details with specific fields (files, bytes, duration, exit code) for Duplicacy snapshots, though doesn't differentiate from sibling get_backup_status.

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?

Provides no guidance on when to use versus alternatives or when not to use.

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