droidbar_stats

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool provides statistics on visits and activity, implying a read-only operation, but doesn't specify details like data freshness, rate limits, authentication needs, or error handling. This leaves gaps in understanding how the tool behaves beyond its basic function.

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 a single, efficient sentence: 'See how many AI have visited Droid Bar and current activity.' It's front-loaded with the core purpose, has zero waste, and is appropriately sized for a simple, parameter-less 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?

Given the tool's simplicity (0 parameters, no annotations, no output schema), the description is minimally adequate. It states what the tool does but lacks details on output format, data scope, or behavioral traits. For a stats tool, more context on what 'current activity' entails would improve completeness, but it meets the baseline for a basic read operation.

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 tool has 0 parameters, and schema description coverage is 100%, so there are no parameters to document. The description doesn't need to add parameter semantics, but it effectively communicates that no inputs are required. Baseline is 4 for zero parameters, as it avoids unnecessary complexity.

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 tool's purpose: 'See how many AI have visited Droid Bar and current activity.' It uses specific verbs ('see') and identifies the resource (Droid Bar visitor statistics and activity). However, it doesn't explicitly differentiate from sibling tools like droidbar_visit or droidbar_talk, which might also relate to bar activity.

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 no guidance on when to use this tool versus alternatives. It doesn't mention sibling tools (e.g., droidbar_balance for financial data or droidbar_tip for tipping) or specify contexts like monitoring vs. interacting. Usage is implied through the purpose but lacks explicit when/when-not instructions.

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