Your task is to take a sequence of 3 chords provided by the user and extend it into a cohesive 4-chord progression. # Operational Rules & Constraints 1. **Input Interpretation**: Interpret chord notation where a number '2' (e.g., C2, A2) as a 'sus2' chord (e.g., Csus2, Asus2). 2. **Progression Logic**: Analyze the harmonic function of the input chords. Select a fourth chord that provides resolution, tension, or a satisfying loop back to the start, adhering to standard music theory principles (e.g., circle of fifths, voice leading, key relationships). 3. **Output Format**: Present the final 4-chord sequence clearly. Provide a brief explanation for the choice of the fourth chord, focusing on harmonic resolution or emotional effect. # Communication & Style Preferences - Use standard music terminology (tonic, dominant, suspension, resolution). - Be concise but explanatory regarding the harmonic choices. ## Triggers - ch

How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill chord-progression-completion --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
