python-error-handling SKILL.md skillA
python-error-handling from wshobson/agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add wshobson/agents/python-error-handling@git:20260522.be57c0bPins git:20260522.be57c0b in mdr.lock. Pin the fingerprint instead.

Python error handling patterns including input validation, exception hierarchies, and partial failure handling. Use when implementing validation logic, designing exception strategies, handling batch processing failures, or building robust APIs.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Python Error Handling
Build robust Python applications with proper input validation, meaningful exceptions, and graceful failure handling. Good error handling makes debugging easier and systems more reliable.
## When to Use This Skill
- Validating user input and API parameters
- Designing exception hierarchies for applications
- Handling partial failures in batch operations
- Converting external data to domain types
- Building user-friendly error messages
- Implementing fail-fast validation patterns
## Core Concepts
### 1. Fail Fast
Validate inputs early, before expensive operations. Report all validation errors at once when possible.
### 2. Meaningful Exceptions
Use appropriate exception types with context. Messages should explain what failed, why, and how to fix it.
### 3. Partial Failures
In batch operations, don't let one failure abort everything. Track successes and failures separately.
### 4. Preserve Context
Chain exceptions to maintain the full error trail for debugging.
## Quick Start
```python
def fetch_page(url: str, page_size: int) -> Page:
if not url:
raise ValueError("'url' is required")
if not 1 <= page_size <= 100:

How to install
mdr add wshobson/agents/python-error-handling@sha256:796346a50615010cThe line at the top of this page pins the label git:20260522.be57c0b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
