get_prop_drilling

Detect prop drilling by tracing parameter names through function chains. Use optional limits or summary-only output to control analysis detail.

Instructions

Detects parameter threading (prop drilling) by finding parameter names passed through chains of functions. Use limit/summary_only to control output.

Behavior3/5

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

No annotations are provided, so the description carries the full burden. It explains the detection method and offers output control hints, but it does not disclose return format, scanning behavior, or potential side effects. This is moderate transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loaded with the purpose and followed by a concise usage hint. There is no filler or redundant information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 10 parameters and no output schema, the description provides a clear core purpose and a key control hint. However, it leaves out details about return values and parameter interplay beyond the schema. It is reasonably complete but not exhaustive.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

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 highlighting limit and summary_only as output control parameters, which helps an agent select them appropriately. This goes slightly beyond the individual schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool detects parameter threading (prop drilling) by finding parameter names passed through function chains. This is a specific verb and resource, and it clearly distinguishes this tool from siblings like get_functions or get_complexity_metrics.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives clear context on the tool's purpose and advises using limit/summary_only to control output. It does not explicitly mention alternatives, but the unique focus on prop drilling makes its use case obvious among the sibling detection tools.

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