# Issue Worker Autonomous issue resolver. Picks up one ready issue, delegates implementation to `mbe agent run` (worktree-isolated), and manages the label lifecycle. ## Workflow ### Step 0: Governor Check Before picking up work, check the adaptive cadence governor: ```bash node plugins/acmm/scripts/cadence-governor.js ``` If the governor exits with code 1 (SKIP), exit cleanly: "Governor says SKIP (mode: \<MODE\>). No work this cycle." If the governor exits with code 0 (EXECUTE), proceed to Step 1. After completing work (Step 5a or 5b), mark that execution happened: ```bash node plugins/acmm/scripts/cadence-governor.js --execute ``` ### Step 1: Find an Issue ```bash gh issue list --label "ready" --state open --limit 5 --sort created --json number,title,body,labels ``` Filter the results to exclude issues that also have the `agent-skip` label. Pick the first issue that passes all filters (no `agent-skip`, dependencies met, etc.). If no issues remain after filtering, **exit cleanly** with a message: "No ready issues found. Nothing to do." ### Step 1b: Check Dependencies Before claiming, check if the issue has unresolved dependencies: ```bash # Extract "Depends on: #N" from issue body DEPS=$(echo "$ISSUE_BODY" | grep -oP 'Depends on: #\K\d+') for DEP in $DEPS; do STATE=$(gh issue view $DEP --json state -q '.state') if [ "$STATE" != "CLOSED" ]; then echo "Blocked: issue #<NUMBER> depends on #$DEP which is still $STATE. Skipping." # Try the next ready i
