analyze_convergence_trend

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It merely states 'analyze convergence trend over time' without indicating whether the operation is read-only, what data it uses, what computation it performs, or any side effects. This is insufficient for an agent to anticipate tool behavior.

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, front-loaded sentence with no unnecessary words. It is concise, though the brevity sacrifices informative content that could aid in understanding.

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 annotations and output schema, the description is overly thin. It does not explain what a convergence trend is, what the return format might be, or how this tool differs from sibling get_convergence. This incompleteness undermines correct invocation.

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 50%, with window documented as 'Number of recent scores to analyze' but session_id lacking any description. The tool description does not elaborate on either parameter, particularly leaving session_id semantics implicit. The description fails to compensate for the missing 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 identifies the action (analyze) and the resource (convergence trend over time for a session). However, it does not explicitly differentiate from the sibling tool get_convergence, relying on the phrase 'trend over time' to imply a temporal analysis.

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 get_convergence or other session tools. No alternatives, prerequisites, or contextual cues are mentioned, leaving the agent without clear selection criteria.

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