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.

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