nexo_startup

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

The description discloses that it cleans stale sessions, which implies a destructive action, and states it returns session ID and alerts. Since no annotations are provided, the description carries the burden, but it lacks details about side effects, authentication needs, or rate limits. It covers essential behavioral traits minimally.

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 extremely concise, consisting of only two sentences that each convey critical information: the tool's function and usage guidance. No extraneous words or redundancy.

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 complexity of the server with many siblings and no output schema, the description is minimally complete. It covers purpose and usage but does not explain what happens on multiple calls, the exact return structure beyond SID, or how parameters like session_token affect behavior. It is adequate but lacks depth.

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 has 100% coverage with descriptions for all 5 parameters. The tool description adds no additional parameter-specific information beyond what the schema provides. The baseline score of 3 is appropriate because the schema already describes parameters.

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 it registers a new session, cleans stale ones, and returns active sessions plus alerts. It uses specific verbs and resource. However, it does not explicitly differentiate itself from the sibling 'nexo_smart_startup', which may have a similar purpose.

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 explicitly instructs to call this once at the start of every conversation. This provides clear context for when to use the tool. However, it does not mention when not to use it or contrast with alternatives.

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