spreadsheet_read_sheet

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

No annotations are provided, so the description bears full responsibility. It correctly implies a non-destructive read operation but does not explicitly state read-only, nor does it disclose authentication needs, rate limits, or potential edge cases like empty sheets. The mention of return structure is helpful but incomplete.

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?

Two concise sentences: first defines purpose and output, second clarifies input selection. No redundant or filler content. Front-loaded with the most critical information.

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?

For a read operation with no output schema, the description adequately states what is returned. However, it lacks details on error handling, empty results, or behavior when both file_id and name are provided. Given the tool's simplicity, it meets basic needs but leaves gaps.

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 100%, so the description adds limited value beyond the schema. It reinforces the 'file_id or name' requirement and summarizes return content, but does not explain parameter interplay (e.g., range vs. sheet_name) or provide examples.

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 it reads cell data from a Synology Spreadsheet sheet and specifies the return structure (headers, data rows, totals). It effectively distinguishes itself from sibling write/append/delete tools by focusing on read-only access.

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 mentions the need to provide file_id or name but does not provide explicit guidance on when to use this tool versus alternatives (e.g., spreadsheet_export for larger datasets). Lacks when-not-to-use or alternative tool references.

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