+## What this is
+
+A curated set of 38 builder skills + 38 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)
+- **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.
+
+## Quickstart
+
+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
+
+```bash
+# Example: install the HARA builder, then ask Claude
+"Build a HARA for a new ECU project — Electronic Stability Control"
+```
+
+## The chain
+
+```
+Item Definition → Safety Plan → DIA
+        ↓
+      HARA → FSC → TSC
+        ↓                ↓
+   HW Lane         SW Lane
+   ↓ ↓ ↓ ↓         ↓ ↓ ↓ ↓
+HW-SR  Arch  HSI  FMEDA   SW-SR  Arch  FMEA  HSI
+        ↓                ↓
+            Safety Case (capstone)
+
+Parallel chains:
+TARA → CS Goals → CS Concept → CS Architecture → IR Plan + Secure Coding   (ISO/SAE 21434)
+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.

+## Why
+
+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).
+
+## Common patterns across the suite
+
+- 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

+## Installation
+
+Each `.skill` file in `skills/` is independently installable. Skills declare triggering descriptions in their frontmatter, so the agent picks them up based on user phrasing (e.g., "build me a HARA" triggers `hara-builder`).
