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

The description implies a write/mutation operation but provides no details on idempotency, overwriting behavior, authentication requirements, storage limits, or side effects. With no annotations, the agent lacks critical behavioral context.

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 sentence, making it concise. However, it is overly minimal and could be restructured to include parameter groupings or usage hints without significant length increase.

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 five optional parameters and no schema descriptions, the tool description fails to explain memory semantics, relationships (e.g., between tags and categories), or the role of memory_id (create vs update). An output schema exists but is not detailed here.

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 0%, and the tool description does not explain any of the five parameters (tags, content, game_id, category, memory_id). The agent has no semantic guidance to correctly populate these fields.

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 the action ('save') and resource ('memory') and scopes it to the current agent. It implies storage, which differentiates from arcade_forget (deletion) and arcade_recall (retrieval). However, it lacks precision on what constitutes a memory (e.g., key-value pairs).

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 on when to use this tool versus alternatives like arcade_forget or arcade_recall. There is no mention of prerequisites, scenarios where saving is appropriate, or cases where it should be avoided.

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