memoryguard_knowledge_book

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

With no annotations and no output schema, the description carries the full burden of behavioral disclosure. It does not state side effects, read/write behavior, permissions, output format, or any operational characteristics beyond the vague 'V2-native' label.

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 short, but it is under-specified rather than usefully concise. It front-loads jargon ('V2-native') and provides no actionable information, so the brevity does not help an agent select or invoke the tool.

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?

Even though the tool has no parameters, an agent has no idea what the tool returns, what action it performs, or how it relates to the many sibling knowledge tools. The definition is not minimally viable for correct tool selection.

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 is an empty object with zero parameters, so the baseline is 4 and no parameter documentation is needed. The description adds no parameter-specific meaning, but none is required.

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 'V2-native knowledge surface.' is effectively a synonym for the tool name 'knowledge_book' rather than a statement of what the tool does. It is a noun phrase with no verb, so an agent cannot tell whether this tool reads, writes, lists, or exposes knowledge.

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 or when to prefer related siblings such as memoryguard_knowledge_read, memoryguard_knowledge_list, or memoryguard_knowledge_search. No alternatives, exclusions, or context are mentioned.

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