"why use many token when few do trick"

✨ Features

• 🎚️ Runtime mode: Reshape assistant output via a persistent compression level (/uc <level>). Auto-Clarity override falls back to prose for destructive/security/ordered turns.
• 📝 File mode: Compress markdown files (skills, agents, memory docs) via /uc-file <path> <level>. Deterministic pre-pass → LLM rewrite → structural validator → targeted repair loop.
• 🪜 Five levels: off, lite, standard, ultra, symbolic — from no change to Greek/math notation.
• 💾 Safe by default: File mode backs up originals to <path>.original.md; /uc-revert restores them.
• 📚 Library API: Importable helpers for other PI extensions to apply the same compression rules.

🪜 Levels

| Level | Effect | |---|---| | off | No modification. | | lite | Drop filler, hedging, pleasantries. Keep articles. | | standard | Drop articles + connectives. Fragments OK. Substitutions. | | ultra | Abbreviations (DB, auth, req, res, fn, impl). Arrow causality. | | symbolic | Math/logic notation (∀ ∃ ∧ → ⟺). Greek vars for repeated concepts. |

📦 Installation

PI discovers the extension automatically once installed as a pi package.

From npm:

pi install npm:@the-forge-flow/ultra-compress-pi

From GitHub:

pi install git:github.com/MonsieurBarti/ultra-compress-pi

Then reload PI with /reload.

🚀 Usage

Commands

| Command | Description | |---|---| | /uc <level> | Set the active level for this project. Autocomplete over the 5 levels. Persists in .pi/ultra-compress.json. | | /uc-file <path> <level> [--yes] | Compress a markdown file. Without --yes, prints a preview. With --yes, writes and backs up to <path>.original.md. | | /uc-status | Show active level, session stats, and recently compressed files. | | /uc-revert <path> | Restore a file from its .original.md backup. |

Library API (for other PI extensions)

import {
  compressText,
  compressTextLexical,
  buildLevelPromptFragment,
  validateCompression,
  getActiveLevel,
} from "@the-forge-flow/ultra-compress-pi";

// In your extension's command/hook handler:
const result = await compressText(markdownBody, "ultra", ctx);

All LLM-backed methods require an active PI ExtensionContext (for model registry access).
