update_alias

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

The description only restates the operation without adding behavioral context beyond the annotations. It does not disclose update semantics, such as partial vs. full replacement, behavior with null fields, or the effect of apply_immediately. Given annotations already cover readOnlyHint=false, idempotentHint=true, and destructiveHint=false, the description adds no additional transparency.

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 a single, compact sentence that is entirely front-loaded with the key information. It contains zero redundant or unnecessary words.

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?

Despite high schema coverage and annotations, the description omits critical operational semantics for an update tool, such as how null parameters are handled, whether the update is partial or wholesale, and the implications of apply_immediately. More context is needed for correct invocation, making the description incomplete for this complexity.

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 description coverage is 100%, with all seven parameters individually described. The description itself adds no parameter-specific meaning beyond mentioning 'by ID', which reinforces alias_id but doesn't go beyond the schema's existing explanation.

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 a specific verb ('Update'), resource ('alias'), and identifier ('by ID'), which distinguishes it from create_alias and delete_alias. However, it does not explicitly differentiate from manage_alias_addresses, which could also be used to modify alias fields, so it's clear but not fully differentiated from all siblings.

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?

No guidance is provided about when to use this tool versus alternatives like create_alias, delete_alias, or manage_alias_addresses. There are no prerequisites, conditions, or exclusions mentioned, so the description offers no decision support.

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