Create Random SimpleLogin Alias

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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the description's 'Create' aligns. The description adds no extra behavioral traits beyond what annotations provide (e.g., rate limits, reversibility, or side effects). With annotations present, the description adds minimal transparency value.

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 two sentences, front-loaded with the action, and every sentence adds value. No unnecessary repetition or fluff.

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 tool with 4 parameters and an output schema, the description covers the key usage (modes, note). It does not mention hostname or account_id, but those are documented in the schema. The description is sufficient for an agent to use the tool correctly, though a brief mention of hostname/account_id could enhance 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?

The description adds meaning for 'mode' (explaining uuid vs word) and 'note' (tagging for audit), which are not fully described in the schema. Schema covers hostname and account_id with descriptions, so the description compliments rather than repeats. Overall, it enriches parameter understanding beyond the schema.

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 it creates a new random SimpleLogin alias, and distinguishes it from siblings by mentioning 'random' and the two modes (uuid/word). Siblings like alias_create_custom are for custom aliases, so purpose is specific and unique.

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 advises when to use each mode: uuid for sensitive signups (hard to guess), word for easier typing. It also mentions optional note for tagging. However, it does not explicitly state when NOT to use this tool vs other alias creation tools like alias_create_custom, missing exclusion guidance.

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