A curated set of 76 builder skills + 76 matching confirmation reviewer skills that automate the structured xlsx deliverables required across the automotive engineering lifecycle:

• ISO 26262 functional safety (concept → HW → SW → safety case)
• ISO/SAE 21434 cybersecurity (TARA → goals → concept → architecture → IR plan)
• ISO 21448 SOTIF for ADAS/AV (analysis → triggering conditions → validation strategy)
• AIAG-VDA quality (APQP → DFMEA → PFMEA → Control Plan → PPAP)
• Automotive SPICE (assessment → gap analysis → improvement → evidence)
• Communication protocols (DBC / LDF / ARXML / FlexRay / Automotive Ethernet / K-Matrix / bus load / gateway routing)
• Diagnostics (UDS / DTC catalog / CDD / ODX / DEM)
• AUTOSAR (Classic SWC, Composition, BSW, RTE; Adaptive applications)
• Calibration (A2L / DCM / cross-supplier exchange)
• MBSE (ARCADIA model architecture, requirements allocation, system context)
• SysML (block diagram, requirement diagram, activity diagram, state machine)
• V&V (verification plan, validation plan, test case catalog, traceability matrix, V&V execution report)
• Chain-integrated program management (risk register, gate review, WP roll-up, change impact, lessons learned)
• Continuous improvement (8D, 5-Why, fishbone, MSA Gauge R&R, SPC)

Each skill is an installable .skill file. The chain is the moat — every downstream skill consumes the upstream skill's xlsx output as a stable file-format contract.

1. Download the skill you need from skills/ (or the full bundle from Releases)
2. Click "Save skill" in Cowork / Claude Desktop to install
3. Trigger by phrasing — every skill declares its triggering description in its frontmatter

# Example: install the HARA builder, then ask Claude
"Build a HARA for a new ECU project — Electronic Stability Control"

Parallel chains:

SOTIF Analysis → Triggering Conditions → Validation Strategy                  (ISO 21448)
APQP Plan → DFMEA → PFMEA → Control Plan → PPAP Package                       (IATF 16949)
ASPICE Assessment → Gap Analysis → Improvement Plan → Process Evidence        (ASPICE PAM)

Every box above has a builder skill AND a matching reviewer skill.

Every automotive program ships an avalanche of structured deliverables. Most teams maintain them in xlsx, painstakingly hand-edited, with low audit-trail consistency and high re-keying overhead between phases. This suite turns each phase into a builder + reviewer pair where:

• The builder produces the structured xlsx output from a JSON input plus the upstream artifact
• The reviewer runs a confirmation-measures checklist on the builder's output and produces a visual dashboard with KPIs, charts, and findings

The chain compounds because phases hand off via stable xlsx contracts. A change upstream (HARA) automatically propagates to every downstream skill that consumes it (FSC → TSC → FMEDA → Safety Case).

• All builder outputs use a consistent NAVY/Calibri styling palette with ASIL/CAL color coding
• All reviewer outputs include visual dashboards (KPI tiles, pie chart, compliance bar, stacked rating breakdown by section, findings table)
• Many reviewers auto-verify quantitative thresholds:
  • FMEDA: SPFM / LFM / PMHF vs ASIL target
  • PPAP: Cpk vs threshold (1.33 standard, 1.67 special characteristics)
  • SW FMEA: residual risk vs ASIL threshold
  • MSA: Gauge R&R % vs AIAG threshold
  • SPC: Cpk vs target
• Reviewers never modify source artifacts — gaps land in Recommended Actions
• Every builder is paired with a reviewer for confirmation-measures compliance
