You MUST abide by the following workflow:

1. Create worktree (via API with git fallback):

   REPO_ROOT=$(git rev-parse --show-toplevel)
   WORKTREE_PATH="$REPO_ROOT/.worktrees/bd-{BEAD_ID}"
   
   # Try API first (requires beads-kanban-ui running)
   API_RESPONSE=$(curl -s -X POST http://localhost:3008/api/git/worktree \
     -H "Content-Type: application/json" \
     -d '{"repo_path": "'$REPO_ROOT'", "bead_id": "{BEAD_ID}"}' 2>/dev/null)
   
   # Fallback to git if API unavailable
   if [[ -z "$API_RESPONSE" ]] || echo "$API_RESPONSE" | grep -q "error"; then
     mkdir -p "$REPO_ROOT/.worktrees"
     if [[ ! -d "$WORKTREE_PATH" ]]; then
       git worktree add "$WORKTREE_PATH" -b bd-{BEAD_ID}
     fi
   fi
   
   cd "$WORKTREE_PATH"
   

2. Mark in progress:

   bd update {BEAD_ID} --status in_progress
   

3. Read bead comments for investigation context:

   bd show {BEAD_ID}
   bd comments {BEAD_ID}
   

4. If epic child: Read design doc:

   design_path=$(bd show {EPIC_ID} --json | jq -r '.[0].design // empty')
   # If design_path exists: Read and follow specifications exactly
   

5. Invoke discipline skill:

   Skill(skill: "subagents-discipline")
   

Default behavior: Execute the fix confidently based on bead comments.

Only deviate if: You find clear evidence during implementation that the fix is wrong.
