python-resource-management SKILL.md skillA
python-resource-management from jartan-llc/grimoire is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add jartan-llc/grimoire/python-resource-management@git:20260731.f6add68Pins git:20260731.f6add68 in mdr.lock. Pin the fingerprint instead.

Python resource management with context managers, cleanup patterns, and streaming.
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 Resource Management
Manage resources deterministically using context managers. Resources like database connections, file handles, and network sockets should be released reliably, even when exceptions occur.
## Core Concepts
### 1. Context Managers
The `with` statement ensures resources are released automatically, even on exceptions.
### 2. Protocol Methods
`__enter__`/`__exit__` for sync, `__aenter__`/`__aexit__` for async resource management.
### 3. Unconditional Cleanup
`__exit__` always runs, regardless of whether an exception occurred.
### 4. Exception Handling
Return `True` from `__exit__` to suppress exceptions, `False` to propagate them.
## Quick Start
```python
from contextlib import contextmanager
@contextmanager
def managed_resource():
resource = acquire_resource()
try:
yield resource
finally:
resource.cleanup()
with managed_resource() as r:
r.do_work()
```
## Fundamental Patterns
### Pattern 1: Class-Based Context Manager
Implement the context manager protocol for complex resources.
```python
class DatabaseConnection:
"""Database connection with automatic cleanup."""

How to install
mdr add jartan-llc/grimoire/python-resource-management@sha256:9274f4507c06b5d9The line at the top of this page pins the label git:20260731.f6add68, 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.
