Description
Avoid common mistakes and debug issues in PydanticAI agents. Use when encountering errors, unexpected behavior, or when reviewing agent implementations.
Usage Guidance
This is a documentation-only skill that provides code examples and debugging tips for PydanticAI agents and appears internally consistent. It does not install code or request secrets. Before running any example code you copy from the doc, review it and only set required environment variables (e.g., OPENAI_API_KEY) in a safe manner; avoid pasting sensitive credentials into public or unknown places. If you plan to execute code from other sources referenced by the examples, inspect those sources first.
Capability Analysis
Type: OpenClaw Skill
Name: pydantic-ai-common-pitfalls
Version: 1.0.1
The skill bundle is a purely educational guide and reference for debugging PydanticAI implementations. It contains documentation and code snippets (SKILL.md) illustrating common developer errors, such as incorrect tool decorators, dependency mismatches, and async/sync mistakes, along with their respective fixes. No malicious code, data exfiltration, or harmful prompt injection attempts were found.
Capability Tags
Capability Assessment
Purpose & Capability
The name/description (PydanticAI pitfalls and debugging) matches the SKILL.md content: examples, fixes, and guidance for agent/tool usage. No unrelated credentials, binaries, or installs are requested.
Instruction Scope
SKILL.md contains code examples, explanations, and debugging advice for PydanticAI agents. It does not instruct the agent to read arbitrary files, exfiltrate data, or call external endpoints beyond noting common environment variables (e.g., OPENAI_API_KEY) relevant to model usage.
Install Mechanism
No install spec and no code files — instruction-only content. Nothing will be downloaded or written to disk by the skill itself.
Credentials
No required environment variables are declared. The doc references OPENAI_API_KEY and model strings only in the expected context of configuring model access — this is proportionate to the guidance being given.
Persistence & Privilege
Skill is not always-enabled and is user-invocable. It does not request persistent system presence or modify other skills; autonomy settings are default and appropriate for an instruction-only helper.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install pydantic-ai-common-pitfalls - After installation, invoke the skill by name or use
/pydantic-ai-common-pitfalls - Provide required inputs per the skill's parameter spec and get structured output
Version History
v1.0.1
- Added a new "Debugging Tips" section detailing practical troubleshooting steps to follow when failures are ambiguous or unclear.
- The new section includes a prioritized checklist ("Gates") for systematically diagnosing agent misbehavior.
- All other existing guidance, patterns, and fixes remain unchanged.
v1.0.0
Initial release: A reference guide to common mistakes and solutions for PydanticAI agent development.
- Documents decorator errors with `@agent.tool` and `@agent.tool_plain`, showing proper and improper usage of `RunContext`.
- Explains correct and incorrect patterns for tool registration, especially when using raw functions in `Agent(tools=[...])`.
- Highlights dependency type mismatches, output type validation issues, async/sync mistakes, and streaming pitfalls.
- Outlines frequent model configuration errors (e.g., API key issues, invalid model string).
- Provides debugging tips, including tracing, capturing messages, and inspecting responses.
- Includes a table of common error messages with causes and fixes.
