clear_all_bookmarks

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

Since no annotations are provided, the description carries the full burden. It transparently states the action is destructive and irreversible. Could add details about lack of confirmation or effects on personalization, but covers the essential behavioral trait.

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?

Single sentence with a warning symbol. Front-loaded with the cautionary indicator, efficient and to the point.

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 0-parameter destructive action with an output schema, the description is complete. It clearly conveys the scope and irreversibility, leaving no ambiguity for the agent.

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?

No parameters in schema, so no need for param details. The description adds value by emphasizing the destructive nature, which is the only relevant semantic context for calling this tool.

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?

Description clearly states 'Delete ALL bookmarks' with verb (delete) and resource (bookmarks). Distinguishes from siblings like 'unbookmark_tweet' or 'delete_tweet' by specifying all bookmarks at once.

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 warning '⚠️ DESTRUCTIVE' and 'Cannot be undone' tells the agent when to use (only if they intend to delete all bookmarks) and implies when not to (if they want to keep any). However, it does not explicitly mention alternatives for deleting individual bookmarks.

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