nexo_recent_context_capture

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

No annotations are provided, so the description must disclose behavioral traits. It mentions state modification ('capture/update') and event appending, but lacks details on side effects, destructiveness, or error conditions. The minimal description is insufficient for safe invocation.

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 very concise at two sentences with no fluff, and front-loads the key action. However, for a tool with 13 parameters, it could have included more critical context without being verbose.

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 the high complexity (13 parameters, no annotations, no output schema, many siblings), the description is extremely incomplete. It omits parameter roles, return values, and differentiation, making it inadequate for correct usage.

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% for 13 parameters, yet the description adds no explanation for any parameter beyond the required title. It fails to compensate for the poor schema documentation.

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 clearly states the verb 'Capture/update' and the resource 'recent 24h context item', and mentions 'append an event'. However, it does not differentiate from siblings like nexo_recent_context or nexo_recent_context_resolve, so it loses a point.

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?

The description provides usage context ('for important ongoing threads that should stay mentally fresh across sessions/clients') but does not specify when not to use it or offer alternatives. The guidance is implied rather than explicit.

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