retro

# Engineering Retrospective ## Product-aware helper ```bash # Claude Code ESCALATE_STATS_RUNNER="$HOME/.claude/src/scripts/escalate-stats.ts" CC_STATE_ROOT="$HOME/.claude" # Standalone Codex would resolve the helper as: # ESCALATE_STATS_RUNNER="${CODEX_HOME:-$HOME/.codex}/darkroom/source/src/scripts/escalate-stats.ts" ``` Codex must skip this Claude escalation telemetry entirely because the plugin does not expose a reliable manual state path. Do not infer or report an act-rate in Codex. **Claude-only marker:** standalone Codex must skip this command. `mkdir -p ~/.claude/tmp && echo "retro" > ~/.claude/tmp/heavy-skill-active && date -u +"%Y-%m-%dT%H:%M:%SZ" >> ~/.claude/tmp/heavy-skill-active` **This skill is self-contained.** Do not read CLAUDE.md or agent definitions. ## Arguments - `/retro` — last 7 days (default) - `/retro 24h` or `/retro 14d` or `/retro 30d` — custom window - `/retro compare` — current 7d vs prior 7d - `/retro compare 14d` — current 14d vs prior 14d **Validation:** Only accept arguments matching `\d+[dhw]`, `compare`, or `compare \d+[dhw]`. Reject anything else with usage instructions. --- ## Step 1: Gather Raw Data Fetch latest from remote, then run 5 parallel git commands: ```bash # Fetch latest git fetch origin main 2>/dev/null # 1.
