depyler: Command for Claude Code

Overnight: Reach 80% Single-Shot Compile

Autonomous improvement loop designed to run all night. Handles ANY starting condition.

Pre-Flight: Handle Any State

cd /home/noah/src/depyler

# Check for uncommitted work - commit it first
if [ -n "$(git status --porcelain)" ]; then
    echo "Found uncommitted changes - committing first"
    cargo test -p depyler-core --quiet
    if [ $? -eq 0 ]; then
        git add -A
        git commit -m "wip: Uncommitted changes from previous session (Refs #193)"
    else
        echo "Tests fail with uncommitted changes - stashing"
        git stash push -m "overnight-stash-$(date +%H%M%S)"
    fi

# Ensure we have latest code

Setup

export LOG="/tmp/depyler-overnight-$(date +%Y%m%d).log"

Main Loop (max 50 iterations)

for iteration in 1..50:
    1. Measure
    2. If >= 80%: SUCCESS, stop
    3. Find highest-impact error pattern
    4. Implement minimal fix
    5. Validate (tests + clippy)
    6. If fail: rollback, try different approach or skip pattern
    7. Measure delta
    8. If improved: commit
    9. If stuck 3x on same pattern: skip, move to next
    10. Log everything

Phase 1: Measure State

cd /home/noah/src/reprorusted-python-cli
make corpus-retranspile 2>&1 | tail -5
RESULT=$(uv run python scripts/measure_compile_rate.py --json)
RATE=$(echo $RESULT | jq -r '.rate')
echo "[$(date)] Rate: $RATE%" >> $LOG

if (( $(echo "$RATE >= 80" | bc -l) )); then
    echo "SUCCESS at $RATE%" >> $LOG
    exit 0
fi

Phase 2: Identify Top Error (Smart Selection)

# Get error frequency with file counts
uv run python scripts/measure_compile_rate.py --json | \
  jq -r '.failing[] | .error' | \
  sed 's/error\[E[0-9]*\]: //' | \
  sort | uniq -c | sort -rn | head -10
