Skill-Compressor

Compress a skill file to reduce token count while preserving all technical information. Use whenever the user drops in a SKILL.md, skill file, system prompt, or agent instruction document and asks to "compress", "shrink", "densify", "reduce tokens", "tighten", or "make smaller" — or when they mention a skill is "too long", "bloated", or "costs too much to load". Applies structural compression (collapsing repeated prefixes, telegraphic tables, symbolic notation) to English-prose skills. Target 40-55% token reduction with zero information loss on technical content.
