nexo_local_index_roots

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

Without annotations, description must disclose behavioral traits. It mentions list/add/remove but does not explain side effects, persistence, permissions, or what 'roots' are.

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?

Single sentence is concise and front-loaded. However, it sacrifices necessary detail for brevity.

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 4 parameters, no output schema, and many sibling tools, the description is far too minimal for correct invocation. Missing parameter details and behavioral context.

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 coverage is 0%, yet description adds no parameter information. It does not explain that 'action' controls operation, 'path' is target, or what 'mode' and 'depth' mean.

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 tool lists, adds, or removes 'local memory roots' – a specific verb-resource combination. However, it does not distinguish from similar sibling tools like nexo_index_add_dir and nexo_index_remove_dir.

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 on when to use this tool versus siblings. For instance, it is unclear when to use nexo_local_index_roots vs nexo_index_add_dir for adding roots.

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