Sync Claude preferences

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the bar is lower; the description reinforces non-mutation ('does not write to Studio', 'writes stay user-confirmed') which matters given the 'sync' name implies writes. It also previews the payload shape (claude_servers, msty_tools, note). Slight duplication of the annotation with 'Read-only' keeps it from a 5.

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?

Front-loaded with the comparison and the delta-report use case, then the exclusions and the alternative. Four short sentences, though 'does not write to Studio' and 'Read-only' say nearly the same thing and could be merged.

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 zero-parameter read-only tool with an output schema and full annotations, the description covers purpose, use case, alternative routing, and mutation safety. Nothing an agent needs in order to call it correctly is missing.

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 takes zero parameters, so the baseline is 4 and there is nothing for the description to disambiguate. It correctly avoids inventing filter options that the empty schema does not support.

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 a specific verb and resource ('Compare Claude Desktop MCP server names with tools already in Msty Toolbox') and names the artifact it produces ('a delta report'). Despite a misleading tool name ('sync'), the description makes clear this is a comparison operation, distinguishing it from siblings like import_tool_config.

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?

It gives an explicit use case ('Use this for a delta report'), an explicit exclusion ('It does not write to Studio'), and routes the write path to a named alternative ('Import missing tools with import_tool_config'). An agent has everything needed to choose between this and the import sibling.

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