# IJFW Compress

IJFW Compress reduces prose in memory or context files while preserving headings, code blocks, URLs, paths, commands, dates, versions, and technical terms. Use it when you need to cut tokens without changing code or meaning.

**Install:**

```bash
npx degit https://github.com/FerroxLabs/ijfw/tree/main/claude/skills/ijfw-compress ~/.claude/skills/ijfw-compress
```

## README

Compress the target file. Preserve all meaning. Reduce tokens.

Rules:
- Drop: articles (a/an/the), filler (just/really/basically), hedging, pleasantries.
- Fragments OK. Short synonyms (big not extensive, fix not implement a solution).
- Arrows for causality (X → Y).
- Abbreviate common terms (DB/auth/config/req/res/fn/impl/env/deps).
- Preserve EXACTLY: code blocks, URLs, file paths, commands, headings, dates, versions, technical terms.
- Only compress prose. Never touch code.

Process:
1. Back up: cp <file> <file>.original.md
2. Compress prose sections.
3. Validate: all headings preserved, all code blocks intact, all URLs unchanged.
4. Report savings as measured per-artifact: "Compressed: <before> -> <after> tokens (<percent>% saved on this artifact)". Report the MEASURED number from wc -w / token-count on the actual files. Do NOT claim a fixed percentage — savings vary widely by input shape (verbose handoffs compress further than dense memory files). v1.5.0 audit removed the legacy hardcoded "50% / 40-50%" framing from this skill in favor of measured-per-receipt reporting.
