analyze_widget_performance

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 only states it analyzes and returns findings, but fails to mention whether it is read-only, has side effects, requires specific permissions, or produces irreversible changes. The description is insufficient for an agent to understand the tool's behavioral footprint.

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 concise with two sentences and front-loads the core purpose. However, it could be slightly more informative without being verbose. Still, it earns a high score for minimal wordiness.

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 9 parameters, no output schema, and many sibling tools, the description lacks completeness. It does not explain the output format, severity levels, or how to use parameters like analysis_depth. The agent would struggle to invoke this tool effectively without additional context.

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 only 44%, meaning 5 out of 9 parameters lack descriptions in the schema. The tool description adds no parameter-level information beyond what is in the schema. It does not explain the meaning or impact of analysis_depth, max_script_length, or other parameters, leaving the agent with incomplete understanding.

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 'analyze' against 'widget performance' and specifies distinct analysis areas (code patterns, transaction logs, provider usage). It mentions the return type (findings with severity). This effectively distinguishes it from sibling tools that involve downloading or managing.

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?

No guidance on when to use this tool versus alternatives. With over 20 sibling tools including audit_local_sources, sn_query, and various diagnostic tools, the description fails to provide any usage context or exclusion criteria.

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