find_wrapper_callers

Identify wrapper classes that call methods of a driver class to understand adapter/wrapper architecture. Clarifies which wrapper methods invoke which driver methods.

Instructions

Read-only. Find wrapper classes that call methods of a driver class.

Returns wrapper methods grouped by wrapper class, showing which driver methods each wrapper calls. Useful for understanding the adapter/wrapper architecture (e.g. UART wraps UART_DRIVER).

Input Schema

limitNoMaximum wrapper method results (default 50).

Behavior3/5

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

With no annotations, the description carries full burden. It declares the tool is read-only and describes the grouping behavior, which adds value. However, it lacks details on prerequisites, error handling, or potential side effects.

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 three concise sentences with the purpose front-loaded. Every sentence contributes value without fluff.

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?

Given the tool's complexity, high schema coverage, and presence of an output schema, the description provides sufficient context about purpose and return grouping. It could benefit from mentioning limitations or index requirements, but overall complete.

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

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the description adds no additional meaning beyond what the input schema provides for each parameter. Baseline 3 applies.

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 finds wrapper classes that call methods of a driver class, using a specific verb ('find') and resource ('wrapper callers'). It distinguishes from sibling tools like find_callers by focusing on the adapter/wrapper pattern.

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 provides clear context for when to use the tool ('understanding the adapter/wrapper architecture') and includes an example, but does not explicitly state when not to use or mention alternatives among siblings.

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