Sister Script
Document-first development. Automate only what's proven.
The document is the source of truth. Scripts are its children.
[!TIP] LIFT stage of play-learn-lift. Proven procedures become automation.
The Pattern
graph TD
D[📄 Document] -->|manual test| C[💻 Commands]
C -->|document| P[📋 Procedure]
P -->|automate| S[🤖 Sister Script]
S -->|improve| D
- Start with natural language (PLAY)
- Add manual commands (PLAY/LEARN)
- Document working procedures (LEARN)
- Generate automation (LIFT)
Bidirectional Evolution
- Document → Script: Proven procedures become automated
- Script → Document: Automation insights improve docs

Sniffable Python: The Structure
Sister scripts should follow sniffable-python/ conventions:
#!/usr/bin/env python3
"""tool-name: One-line description.
Docstring becomes --help AND is visible to LLM.
"""
import argparse
def main():
"""CLI structure — sniff this to understand the tool."""
parser = argparse.ArgumentParser(description=__doc__.split('\n')[0])
# ... CLI tree here ...
args = parser.parse_args()
_dispatch(args)
# Implementation below the fold
Why sniffable Python for sister scripts?
- LLM can read
main()and understand the CLI - Human can run
--helpfor the same info - Single source of truth for documentation
- One sniff and you smell success
