Toggle SimpleLogin Alias

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

Describes that disabling blocks incoming mail without deleting the alias record, adding behavioral detail beyond annotations (readOnlyHint, destructiveHint, idempotentHint). No contradiction with annotations, though idempotency is not explained.

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: first states the function, second explains the effect. No extraneous words, front-loaded with action. Highly efficient.

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?

Given a simple toggle with annotations covering idempotent/non-destructive and an output schema present, the description explains core behavior. Could mention prerequisites (e.g., alias must exist) or explicitly note idempotency, but overall adequate.

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?

Description does not mention any parameters. Schema has 2 parameters with 50% coverage (only account_id described in schema). The description adds no additional meaning, failing to compensate for the incomplete schema documentation.

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?

Clearly states 'Enable or disable a SimpleLogin alias', identifying the action (toggle) and resource (alias). Distinguishes from deletion by explaining that disabling blocks mail without deleting, differentiating it from sibling alias_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?

Provides a use case ('useful when a service starts abusing an alias') but does not explicitly state when not to use or compare with alternatives like alias_update or alias_delete. The context is clear but lacks exclusions.

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