skill-zipper

What problem does it solve?

Skills degrade as they grow: bloated always-loaded content wastes tokens on every invocation, vague rules lead to inconsistent model behavior, and poor frontmatter descriptions cause mis-triggering or complete failure to load. This skill performs a lossless restructuring that trims size, tightens instructions, and fixes triggering without changing what the skill does.

Core Features & Use Cases

• Lossless Restructuring: Compresses and reorganizes skill content while preserving every line of behavior and instruction, verified by diff scripts.
• Token Efficiency: Moves content to on-demand files and removes model-known redundancy to reduce always-loaded token cost.
• Trigger Accuracy: Rewrites the frontmatter description using a rubric to ensure the skill loads on the right turns and skips irrelevant ones.
• Portability Audit: v2.0 includes a checklist to align skills with the open standard's portable core fields for cross-runtime compatibility.

Quick Start

Use the skill-zipper skill to restructure the attached skill directory for better token efficiency and trigger accuracy.
