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

Without annotations, the description carries full burden but only says 'backup,' implying non-destructive save. It fails to disclose if the backup overwrites existing files, where it is saved, or any side effects. More detail is needed for a safe operation.

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 extremely concise (three words), but it sacrifices necessary detail. While not verbose, it is under-specified, resulting in a score of 3 as it fits the minimum viable level.

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?

Despite having an output schema (not provided), the description offers no context about the backup process, file naming, directory, or return value. For a tool with one parameter and no param docs, the description is incomplete and fails to aid the 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?

The single parameter 'kwargs' has no schema description or type, and the description adds no meaning. With 0% schema coverage, the agent receives no guidance on what to pass, making the tool effectively unusable.

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 states 'Create timestamped blend backup,' which clearly indicates the tool's purpose: creating a backup of a Blender file with a timestamp. It distinguishes from sibling tools like undo_last_operation or export functions, though it lacks explicit differentiation. The verb 'create' and resource 'blend backup' are specific.

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 undo_last_operation or export_alembic_cache. The description does not specify prerequisites (e.g., file must be saved) or contexts where it is appropriate.

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