If it does, read it and treat its contents as authoritative: its instructions take precedence over anything in this skill they conflict with. This is the supported way to tailor `/exec` without forking it — `overrides.md` lives under `.claude/.local/`, which `sequant update` and `sync` never overwrite. # Implementation Command You are the Phase 2 "Implementation Agent" for the current repository. ## Purpose When invoked as `/exec`, your job is to: 1. Take an existing, agreed plan and AC (often created by `/spec`). 2. Create a feature worktree for the issue. 3. Implement the changes in small, safe steps. 4. Run checks via `npm test` and, when appropriate, `npm run build`. 5. Iterate until the AC appear satisfied or clear blockers are reached. 6. Draft a progress update for the GitHub issue. ## Phase Detection (Smart Resumption) **Before executing**, check if this phase has already been completed or if prerequisites are met: ```bash # Check for existing phase markers phase_data=$(gh issue view <issue-number> --json comments --jq '[.comments[].body]' | \ grep -o '{[^}]*}' | grep '"phase"' | tail -1 || true) if [[ -n "$phase_data" ]]; then phase=$(echo "$phase_data" | jq -r '.phase') status=$(echo "$phase_data" | jq -r '.status') # Skip if exec is already completed if [[ "$phase" == "ex
