# Analyze Agent Tool Interfaces

Agent frameworks often hide how tools are registered, validated, and retried. This skill guides a structured review of tool abstractions, schemas, built-in tools, and error feedback.

## Capabilities

- Maps how a framework represents tools through classes, protocols, functions, or Pydantic models.
- Compares schema generation methods such as introspection, Pydantic models, decorators, and manual definitions.
- Documents registration and discovery patterns, including declarative lists, registries, factories, and toolkits.
- Reviews tool execution, validation, error formatting, retry behavior, and LLM self-correction loops.
- Produces a structured Markdown analysis with code references and implementation tradeoffs.

## Use Cases

- Review a new agent framework: Identify how the framework defines tools, validates arguments, and exposes tools to the model.
- Compare tool-calling designs: Build consistent notes across frameworks before selecting patterns for a new implementation.
- Improve retry and error feedback: Trace how failures are returned to the model and where self-correction can be strengthened.

## Prompt Templates

### Map tool basics

```
Analyze this framework with tool-interface-analysis. Start with tool modeling, schema generation, registration, execution, and error feedback.
```

### Compare schema methods

```
Use tool-interface-analysis to compare how this framework generates tool schemas. Note introspection, Pydantic, decorator, and manual patterns with file references.
```

### Audit retry behavior

```
Use tool-interface-analysis to trace validation failures, execution errors, retry rules, and LLM self-correction feedback in this codebase.
```

### Create architecture recommendations

```
Analyze these frameworks with tool-interface-analysis and produce recommendations for a new agent tool layer, including tradeoffs and anti-patterns.
```

## Limitations

- Requires access to the target framework source code for useful results.
- Does not execute or test the target framework by itself.
- May need manual judgment when frameworks mix several tool patterns.
- Focuses on tool interfaces, not provider wire formats or streaming protocols.

## Best Practices

- Start with the framework files that define base tools, schemas, registries, executors, and validation.
- Record file and line references for each claim in the output document.
- Separate interface design findings from provider protocol findings.

## Anti Patterns

- Do not infer schema behavior from examples without checking implementation code.
- Do not mix tool interface analysis with unrelated provider message-format analysis.
- Do not treat missing retry behavior as confirmed until execution paths are traced.

## Security Audit

- Audited at: 2026-07-06T12:27:10.122\+00:00
- Summary: All static findings reviewed were false positives caused by Markdown code fences, inline code formatting, placeholder api\_key examples, and illustrative Python snippets. I found no prompt injection, credential exposure, command execution, or system reconnaissance intent in SKILL.md.
