memory_alias_add

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

With no annotations provided, the description carries the burden of behavioral disclosure. 'Add or update' usefully signals upsert behavior rather than a simple create, but it does not explain whether existing aliases are replaced, whether the canonical entity must already exist, how tags are handled, or what side effects occur.

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 one short sentence with no filler and the action verb is front-loaded. It is appropriately concise for a simple CRUD tool, though it is terse enough that some semantic burden falls on the schema.

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 no annotations, minimal parameter descriptions, and a simple but nonzero input schema, the description is too thin to fully guide correct invocation. It leaves ambiguous what a canonical entity is, how aliases are stored or updated, and whether tags are merely metadata or affect behavior.

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 schema has 0% description coverage and only title-level parameter names. The description adds some meaning by framing 'entity' as canonical and 'alias' as the associated synonym, but it says nothing about the 'tags' parameter, required vs optional roles, formatting, or allowed values.

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 names a specific action ('Add or update') and a specific resource ('an alias for a canonical entity'), so an agent can tell this is alias-management rather than generic memory writes. It does not explicitly differentiate from related tools like memory_alias_list or memory_update, but the resource focus is clear.

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?

There is no guidance on when to use this tool versus alternatives such as memory_alias_list or memory_add. The description implies the purpose but provides no context about prerequisites, exclusions, or the preferred situation for calling this tool.

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