vm-ease-classifier

# vm-ease-classifier

## When To Use This Skill

- Individual incident tickets need independent 0-1 EASE lever scores after clustering and ITSM classification
- An operations team needs each incident scored on all four resolution strategies (Eliminate, Automate, Shift Left, Empower Users)
- Cluster-level EASE classification is needed by aggregating per-incident scores

**Do NOT use this skill when:**
- Ticket clustering has not yet been performed (cluster first with `vm-ticket-cluster-analyzer`)
- ITSM classification has not been applied (classify first -- ITSM categories inform EASE scoring)
- The goal is to explain the EASE framework to stakeholders (the invoking agent handles that outside this skill)

## Unitary Function

**ONE RESPONSIBILITY:** Apply the EASE decision rules from `references/ease-framework.md` to each individual ticket and return independent 0-1 scores for all four EASE levers, plus a cluster-level aggregate classification.

**NOT RESPONSIBLE FOR:**
- Producing the ticket cluster array (that is `vm-ticket-cluster-analyzer`)
- ITSM domain classification (the invoking agent handles that before calling this skill)
- Temporal pattern analysis or L-3 candidacy scoring (invoking agent's workflow responsibilities)
- Defining or explaining the EASE framework to users
- Generating the final JSON report (that is `sdlc-artifact-generator`)
- Reading ticket source files
