create_sync_history_remove

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

The description adds little beyond the operation name and endpoint; it doesn't describe side effects, response behavior, or why the operation is idempotent. The annotations already indicate idempotentHint and destructiveHint, but the description itself contributes no further behavioral context.

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 short, front-loaded, and every line serves a purpose. The HTTP path and prerequisite are useful, though the path partly repeats the tool name without adding much.

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 an open-world body schema, the pointer to the matching GET and /schema endpoint is essential and present, and an output schema exists so return values are covered. Still, it omits what kind of history items are expected and any authentication or prerequisite details, leaving it short of fully self-contained.

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?

With 0% schema description coverage, the description needed to compensate, but it only labels body as 'Request payload' and points to the GET/schema endpoint. This is actionable but doesn't explain expected fields, structure, or item identifiers, so the agent still must perform an external lookup.

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 the specific action 'Remove items from history' and includes the HTTP path, which distinguishes it from generic CRUD tools. However, it doesn't explicitly connect the tool to sync history or contrast it with sibling removal tools like create_sync_collection_remove or create_sync_watchlist_remove.

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 gives a clear context for use—removing history items—and provides a prerequisite: read the matching GET or /schema endpoint first. It does not explicitly explain when to choose this tool over its many sibling remove tools, leaving some selection inference to the agent.

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