▸ scripy

Generate small, single-file scripts using locally hosted LLMs. Ideal when presented with repetitive terminal tasks. Available in the command line when you need it.

scripy -p "rename all my jpegs by date taken"

scripy runs an agentic loop: generate, validate, self-correct, and write entirely on your machine via Ollama or LM Studio.

---

Install

Requires Python 3.11+ and a running Ollama or LM Studio instance.

pip install scripy-cli

Or for development:

pip install -e .

---

Quick start

Note: This assumes you're running Ollama on the same machine with qwen2.5-coder:7b installed. See Configuration below for more detailed configuration steps.

# Generate a Python script
scripy -p "find duplicate files in a directory"

# Specify output file
scripy -p "find duplicate files in a directory" -o dedup.py

# Generate Bash
scripy -p "backup my home directory to /tmp" --lang bash

# Modify an existing script
scripy -p "add a --dry-run flag" --input dedup.py

# Skip all confirmation prompts (for scripting)
scripy -p "..." -y

---

Confirmation gates

scripy prompts for user input before any side-effectful action.

Before writing to disk:

  ? write to disk as dedup.py? [y/n/v] ›

Before sandboxed execution:

  ? run script to validate? [y/n/e/v/a] ›

Key	Action
y	Yes
n	No
e	Open in $EDITOR to manually edit
v	Print script to terminal, then re-prompt
a	Always yes - skip gate for all remaining iterations

Use -y / --yes to bypass all gates non-interactively.

---

Configuration

Default config works with a local Ollama instance. Override via ~/.config/scripy/config.toml:

[model]
  base_url    = "http://192.168.1.10:11434/v1"  # remote Ollama
  model       = "llama3.1:8b"
  api_key     = "ollama" # use "lm-studio" for LM Studio
  temperature = 0.2
  max_tokens  = 4096

[agent]
  force_tools      = true
  max_iterations   = 3
  default_lang     = "python"
  sandbox_timeout  = 10

CLI flags override config for a single run:

scripy --model qwen2.5-coder:7b -p "..."

Model recommendations

scripy targets models that run on small consumer hardware (~4–8GB RAM) but will obviously excel on more powerful machines. That being said, here are some recommendations for small machines.

Model	Size	Tool calling	Code quality	Notes
llama3.1:8b	~4.7GB	Native	Good	Recommended default
llama3.2:3b	~2.0GB	Native	Fair	Best ultra-low-resource option
qwen2.5-coder:7b	~4.4GB	Inline only	Excellent	Best code quality; see note below
deepseek-coder:6.7b	~4.0GB	Inline only	Excellent	Same trade-off as qwen-coder

Tool calling

scripy uses the OpenAI function-calling API to let the model invoke tools (write_file, run_script, read_file, list_directory). Models generally fall into two categories:

Native tool calling (llama3.1, llama3.2) - the model returns structured tool_calls in the API response. The agentic loop runs cleanly; run_script validation and multi-turn self-correction work as intended.

Inline tool calling (qwen2.5-coder, deepseek-coder) - these models sometimes ignore the tool-calling API and instead append a JSON blob to their text response. scripy tries to detect and strip these automatically, but the behavior is less reliable and the self-correction loop may not fire. You may see:

  ~ inline tool call detected - model is not using structured tool calling

--force-tools (tool_choice=required) is on by default. This works well with native tool-calling models and is generally the right choice. If you see errors or garbled output, which can happen with certain qwen-coder or deepseek-coder models on older Ollama versions, disable it via config:

# ~/.config/scripy/config.toml
[agent]
  force_tools = false

With force_tools off, scripy falls back to inline tool-call detection automatically. I've personally had better results using LM Studio for smaller models on small hardware (think M2 mac mini 8GB RAM). Sometimes using Ollama the model kept appending tool calls to the script output.
