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

No annotations are provided, so the description carries the full burden. It does not explicitly state that this is a read-only operation, whether it has side effects, or what happens when no memories match. The phrase 'for the current agent' adds scope but is insufficient for an operation with 8 parameters and no annotation safety profile.

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, which is concise, but it is under-specified rather than efficiently concise. It front-loads the core idea but omits essential details, making it less useful than a longer, well-structured description.

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 8 parameters, no annotations, and no insight into the output schema, the description is grossly incomplete. It fails to explain how to retrieve a specific memory, how filters combine, what the default behavior is, or what the returned data looks like. For a tool of this complexity, this is inadequate.

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%, meaning no parameter descriptions exist in the schema. The description mentions 'tag', 'search', 'category', etc., but does not explain any of them. For a tool with 8 parameters, the description should at least clarify how filtering works, the meaning of 'limit', and the special role of 'memory_id' for single retrieval.

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 states the verb 'Recall' and the resource 'memories' for the current agent, which is clear enough to distinguish it from siblings like arcade_remember (store) and arcade_forget (delete). However, it doesn't hint at the filtering or retrieval modes (single vs list) beyond the words 'one memory or a filtered list', which is somewhat ambiguous given the 8 parameters.

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 arcade_history or arcade_state. No mention of prerequisites, exclusions, or typical use cases. The agent must infer from the name alone that this retrieves memories.

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