create_workbook_snapshot

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

The description says the tool creates a snapshot 'without overwriting an existing file,' yet the annotations mark it with destructiveHint=true. This is a direct contradiction: the description disclaims the destructive behavior the annotation warns about, and neither explains the 'verified' aspect further.

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, front-loaded sentence with no filler. It delivers the action, the output type, and the key safety constraint in minimal space.

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?

With 0% schema coverage, no output schema, and a contradictory destructiveHint, the definition is incomplete for safe invocation. The simple two-parameter shape makes the basics inferable, but an agent cannot learn what 'verified' means, what happens if the snapshot path exists, or what a successful call returns.

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 coverage is 0%, and the description does not define filepath or snapshot_filepath or their relationship. The only parameter-related clue is the 'without overwriting' constraint, which gives one behavioral detail about snapshot_filepath but leaves formats, source/destination roles, and failure behavior undocumented.

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 begins with a specific verb and object: 'Create a verified workbook snapshot.' The added constraint 'without overwriting an existing file' clarifies the operation's scope and distinguishes it from plain workbook creation or copying tools among the siblings.

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 implies a backup/verification use case for a workbook, but it never states when to use this tool versus alternatives or what conditions make it the right choice. No sibling tool performs snapshots, so the intent is inferable, but the guidance is only implicit.

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