local codegen workflow
Generate production code with a local LLM on the GPU you already own. Spec-driven codegen via LM Studio/Ollama/vLLM, with auto model-loading, a 13-bug review checklist, and a working genfile script — all model-agnostic.

local codegen workflow
Example session with this skill installed
I need a Python module for an LRU cache. It should use the standard library only, support a max_size, and have get/put methods. Save it to lru_cache.py using the local Qwen model.
- Read your context and instructions
- Compiled the local codegen workflow
I have generated the lru_cache.py module using the local qwen2.5-coder-14b-instruct model. The model was pre-loaded at a 32k context window to ensure VRAM stability.
Generated LRU Cache Module
from collections import OrderedDict
class LRUCache:
"""
A simple LRU Cache using OrderedDict.
"""
def __init__(self, max_size: int = 128):
if max_size <= 0:
raise ValueError("max_size must be positive")
self.cache = OrderedDict()
self.max_size = max_size
def get(self, key):
if key not in self.cache:
return None
self.cache.move_to_end(key)
return self.cache[key]
def put(self, key, value):
if key in self.cache:
self.cache.move_to_end(key)
self.cache[key] = value
if len(self.cache) > self.max_size:
self.cache.popitem(last=False)
if __name__ == "__main__":
# Smoke test
lru = LRUCache(2)
lru.put(1, "a")
lru.put(2, "b")
print(lru.get(1)) # a
lru.put(3, "c") # evicts 2
print(lru.get(2)) # None

About this skill
The problem
Paying per-token API costs for repetitive boilerplate and large-scale code generation is expensive. Local LLMs often fail during generation due to OOM errors because they are loaded with default context windows that exceed available VRAM.
What it does
- Automates the spec-driven generation of production code using local LLM servers.
- Manages VRAM-safe model loading via LM Studio v1 REST API to prevent OOM "terminated" errors.
- Enforces a senior-level review checklist to catch common local model fumbles like connection leaks and empty-list SQL crashes.
- Implements a 2-strike rule to prevent time-wasting loops on low-quality generations.
- Generates both the implementation module and its corresponding test suite from a single source-of-truth spec.
Frameworks & tools
Python 3.11, httpx, LM Studio, Ollama, vLLM, Qwen2.5-Coder, DeepSeek-Coder.
Why this beats prompting it yourself
Standard prompting often results in code blocks wrapped in conversational prose that break automation scripts. This skill includes a specialized extraction layer and a model-management handshake that ensures the model is actually loaded at a stable context length before the first token is even generated.
Use cases
- Generating large volumes of boilerplate for new microservices without incurring API fees.
- Prototyping internal tools where data privacy prevents sending code to third-party APIs.
- Setting up a repeatable generate-review-test-commit pipeline for junior-level tasks.
Known limitations
Not recommended for surgical edits to existing complex files. Requires a GPU with at least 8GB VRAM for 7B models or 16GB for 14B models.
