get_sync_status

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

Beyond the annotations (readOnlyHint, destructiveHint, openWorldHint), the description adds meaningful behavioral details: the output JSON structure, that 'errors' contains non-fatal error strings, and that the runs list is empty when no sync has been run. This provides context about edge cases and return semantics that annotations do not cover.

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 concise, well-structured, and front-loaded with the main purpose. It uses a clear hierarchy: summary sentence, then details about timestamps and errors, then an explicit return format. Every sentence adds information without redundancy.

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?

This tool has no parameters, a read-only annotation, and an output schema, yet the description still covers key edge cases (empty runs list, non-fatal errors, timestamp units). It is complete and self-contained, enabling the agent to understand exactly what to expect without needing additional context.

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 tool has no parameters, and the schema coverage is trivially 100%. The description still adds value by explaining the output fields and their meanings, though parameter-level semantics are not applicable. Given the zero-parameter baseline of 4, this score is appropriate.

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 starts with a clear, specific verb and resource: 'Report the last sync run for each standards body.' This distinguishes it from sibling tools that handle papers, books, standards, or tasks, and leaves no ambiguity about what the tool does.

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 clearly states the tool's function and output scope ('One row per body'), making the intended use context obvious. It does not explicitly mention alternatives or exclusions, but given the unique subject matter among siblings, the usage context is clear enough to earn a 4.

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