What this solves

AI agents are powerful — but they don't know 8D from PDCA, can't apply the AIAG-VDA Action Priority table, and generate generic NCR text that no auditor would accept.

Quality-Engineering-Skills packages decades of hands-on quality engineering expertise — automotive supplier quality, claims management, 8D, FMEA, PPAP, and ISO 9001 auditing — into structured skills your AI agent can load and apply immediately.

Every skill maps to specific standard clauses. Every agent validates methodology, not just format.

8 Agents

Drop these into any project and your AI becomes a trained quality professional.

/8d-coach

Guides you through a full 8D — D0 emergency response to D8 team recognition. Validates root cause depth (rejects "human error" without systemic analysis), verifies containment before moving to D4, and checks D7 prevention updates.

/8d-coach
> D0: Is this a safety or regulatory issue? [Y/N]
> D1: List team members by function (minimum: quality, production, engineering)
> D2: Describe the defect — What? Where? When? How many? ...

/fmea-reviewer

Audits an existing PFMEA or DFMEA against AIAG-VDA 2019. Returns a structured gap report: missing failure modes, incorrect AP ratings, unaddressed H-AP items, missing special characteristics.

/rca-facilitator

Runs a structured 5-Why with chain validation. Challenges each answer with evidence requirements. Detects symptomatic vs. systemic root causes. Catches circular reasoning. Produces a validated, reversible Why chain.

/ncr-writer

Takes bullet-point observations and generates professional NCR text: objective evidence language, severity classification (Critical/Major/Minor), and disposition recommendation. No more "part looks wrong."

/audit-guide

Interactive internal audit for ISO 9001 or IATF 16949. Works clause by clause, scores findings (Major/Minor/OFI), generates a structured audit report with evidence references.

/ppap-checker

Interactive PPAP completeness checker — walks through all 18 PPAP elements for the requested submission level, flags missing or incomplete items, and generates a gap report before PSW signature.

/control-plan-builder

Builds a Control Plan row by row from PFMEA failure modes and process flow steps. Validates reaction plans, sample plans, and special characteristic coverage. Supports D7 update mode after corrective actions.

/skill-auditor

Automated audit and scoring of SKILL.md and REFERENCE files against framework standards.
