Create Logins

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

Given minimal annotations (only readOnlyHint=false, destructiveHint=false), the description adds valuable behavioral context: continueOnError keeps going after failure, returned items are redacted by default, and per-item ok/error results are provided. No contradiction with annotations.

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 sentences, front-loaded with purpose. Every sentence adds value: first states purpose, second adds usage guidance and behavioral details. No 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?

No output schema exists. Description mentions redacted returns and per-item results but lacks detail on the exact return structure (e.g., IDs, error format). It references create_login for behavior, but for a complex batch tool, more specificity would improve completeness.

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?

Schema coverage is 100%, so baseline is 3. The description adds meaning beyond schema by explaining the items parameter as 'each item follows create_login fields' and continuesOnError behavior. This extra context raises the score to 4.

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 clearly states the tool's purpose: 'Create multiple login items in one call.' It uses a specific verb (create) and resource (login items), and distinguishes it from the sibling 'create_login' by highlighting batch capability.

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?

Provides explicit usage context: 'Use this when you need several independent credentials at once.' References behavior of create_login for consistency. Mentions continueOnError for handling failures, offering guidance on error handling. No explicit when-not-to-use, but the batch vs single distinction is clear.

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