memory_recall

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

No annotations provided, so description carries full burden. It discloses the default namespace and parameter meaning but omits critical details: what happens if the key does not exist, the format/value type of the recalled data, any side effects (likely read-only), or error handling.

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?

Very concise: two-sentence main description followed by structured arg list. No redundant information, front-loaded with core action.

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 simple retrieval tool, the description covers the core functionality and parameter defaults. However, it lacks mention of return value (partially covered by presence of output schema) and usage context relative to other memory tools. Adequate but not comprehensive.

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%, so description compensates minimally. It adds meaning by naming 'Memory key to recall' and 'Memory namespace (default "default")'. This is basic but sufficient for parameters with no enums or complex constraints.

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?

Description clearly states 'Recall a value from agent memory' with specific verb and resource. Among sibling memory tools (memory_store, memory_search, memory_list_entries, etc.), it is distinctly the key-based retrieval operation, avoiding confusion.

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 on when to use this tool versus alternatives like memory_search or memory_query. The description does not mention prerequisites, when-not-to-use, or contrast with sibling tools.

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