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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Recall' implies a read operation, but the description doesn't state whether it has side effects, what happens when no key is provided, or what the return value looks like.

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 concise sentence with no wasted words, and the core action is front-loaded. It is efficient but arguably too terse to fully support tool selection and invocation.

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?

With no annotations and no output schema, the description leaves important context unstated: what a recall returns, what the optional key changes, and what 'claimed owner's desk' refers to. The tool is simple, but the description is not complete enough for an agent to invoke it confidently.

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 the description needed to explain what 'key' means and how it affects the recall. It only says 'Optional key,' which mostly restates that there are no required parameters, and provides no semantic detail about whether key is an ID, a lookup value, a category, or something else.

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 ('Recall notes') and a resource ('the claimed owner's desk'), clearly identifying this as a retrieval tool for notes. It is not a tautology, and the sibling name memory_write hints at a read/write contrast, but the description doesn't explicitly differentiate from siblings.

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 about when to use this tool versus memory_write or any other alternative, no prerequisites, and no exclusions. The only contextual hint is the word 'Recall' paired with the sibling name memory_write, which is not explicit enough.

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