nexo_startup

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

No annotations are provided, so the description bears full burden. It discloses that it registers sessions and cleans stale ones (mutation), but doesn't detail authentication requirements, rate limits, or the exact nature of 'alerts.' Some behavioral aspects are implied but not fully explicit.

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?

Two concise sentences that front-load the core function and then provide critical usage instruction. No wasted words.

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 absence of output schema, the description adequately covers key return values (active sessions, alerts, SID). However, it could specify the format or structure of 'active sessions' and 'alerts' for clarity.

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 100%, so the baseline is 3. The description adds value by explaining the importance of the session ID (SID) for other tools, but doesn't significantly expand on parameter semantics beyond what the schema already provides.

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?

Clearly states it registers a new session, cleans stale ones, and returns active sessions plus alerts. The verb 'register' and resource 'session' are specific. Distinguishes itself from sibling tools like nexo_smart_startup by being the primary initialization tool.

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?

Explicitly instructs to call it once at the start of every conversation. Tells the agent to store the returned session ID for use in all other nexo_ tools, providing clear when-to-use guidance and action items.

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