Compress one or more SKILL.md files so they consume less context on load while preserving 100% of their value — same triggers, capabilities, guardrails, thresholds, and output. Use when the user says 'compress this skill', 'optimize skills for context', 'make skills use less context', 'slim down the skills', 'reduce skill token usage', 'shrink SKILL.md', or wants a skill or whole skill suite trimmed without losing behavior.
