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

With no annotations provided, the description carries full responsibility for disclosing behavior. It mentions session scope, which is useful, but does not state whether the operation is read-only, how results are returned, what happens when no memories exist, or how the optional skill_name parameter affects behavior.

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 very short and the session-scope detail is front-loaded. However, the word 'Storefront' is a cryptic metaphor rather than a clear action, and the description is so minimal that it sacrifices useful information for brevity.

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 no annotations, no output schema, and one undocumented parameter, this description is incomplete. It fails to explain the meaning of skill_name, the output shape, or behavioral side effects, so an agent cannot reliably select and invoke the tool correctly.

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 input schema describes skill_name only as a string with no description, and schema description coverage is 0%. The tool description never mentions skill_name or explains how it filters or scopes the recalled memories, leaving the agent without enough information to populate the parameter correctly.

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 identifies the resource as memories saved in the current session, which combined with the tool name 'recall_memories' clearly conveys a retrieval/listing operation. It is distinguishable from the sibling 'save_memory', though it does not use an explicit verb like 'get' or 'list'.

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 explicit guidance is given about when to use this tool versus alternatives. The session-scoped wording implies it is for accessing in-session memories, but there are no stated conditions, exclusions, or comparisons to sibling tools.

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