Trinity Compress (Skill)

Pre-run prompt compression for iterative AI dev loops.

Goal: reduce input tokens every iteration by compressing prompt files before your loop runs.

• Works with Ralph-style loops, agent/skill directories, and most token-billed providers.
• Runs as a local script (no model calls).
• Creates .bak backups and supports instant undo.

What it installs into a repo

• trinity-compress.config.json — rules + targets
• scripts/trinity-compress.sh — compression script
• Makefile snippet (optional): optimize-prompts, optimize-undo, etc.
• .gitignore snippet: ignore *.bak
• Installers:
• scripts/install.ps1 (Windows)
• scripts/install.sh (bash)

Requirements

Use

1) Install into your repo (copy assets or use the included installer scripts)

2) Run:

• bash scripts/trinity-compress.sh balanced

Undo

• Restores all *.bak backups from the last run.

Notes

• This tool does not rewrite code blocks, URLs, file paths, or variable names.
• Aggressive mode may reduce clarity; review before committing.
