RTL Pipeline Orchestrator

This skill IS the plan �� execute each stage immediately using Read/Write/Bash tools. Do NOT plan before executing.

Project directory path: $ARGUMENTS

If $ARGUMENTS is empty, ask the user for it.

Step 0: Initialization

Execute immediately:

PROJECT_DIR="$ARGUMENTS"
ls -la "$PROJECT_DIR/requirement.md" || { echo "ERROR: requirement.md not found"; exit 1; }
cd "$PROJECT_DIR" && mkdir -p workspace/docs workspace/rtl workspace/tb workspace/sim workspace/synth .veriflow logs

echo "[INPUT] requirement.md: $(test -f requirement.md && echo YES || echo NO)"
echo "[INPUT] constraints.md: $(test -f constraints.md && echo YES || echo NO)"
echo "[INPUT] design_intent.md: $(test -f design_intent.md && echo YES || echo NO)"
echo "[INPUT] context/: $(ls context/*.md 2>/dev/null | wc -l) file(s)"
ls context/*.md 2>/dev/null || true
