bulk_update

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

With no annotations, description should disclose more behavioral details like atomicity, error handling, or response format. Only mentions limit, missing key traits for a mutation tool.

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 that front-load essential info: purpose and constraint. No verbose filler.

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?

Covers basic usage but lacks return value details and fails to address what happens on partial failure. For a batch mutation tool, more completeness expected given no output schema.

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?

Input schema has full descriptions for all properties (100% coverage), so description adds minimal value beyond stating structure. Baseline 3 holds.

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 'Update multiple memories at once' with specific resource (memories) and action (update), distinguishing from sibling tools like update_memory and bulk_delete.

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?

Implies usage for batch updating memories but lacks explicit guidance on when to use versus single update_memory or other bulk operations. Mentions max 50 items as constraint.

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