    Start([What do you want to do?]) --> Q1{Intent?}

    Q1 -->|Capture new work —<br>bug, feature idea, observation| Create["/dh:create-backlog-item<br>Modes: guided intake, quick title, --auto title<br>Writes to ~/.dh/projects/{slug}/backlog/"]

    Q1 -->|Prepare an item for planning —<br>verify claims, map impact, estimate effort| Groom["/dh:groom-backlog-item {title|section|all}<br>RT-ICA + parallel swarm: fact-checker,<br>impact-analyst, rtica-assessor, classifier, groomer<br>Requires: item exists in backlog"]

    Q1 -->|Plan AND execute a backlog item<br>end-to-end through closure| Work["/dh:work-backlog-item {title|#N|--auto}<br>Handles: auto-groom, RT-ICA gate, SAM planning,<br>GitHub sync, close, resolve<br>STOPS if item already has a Plan field"]

    Q1 -->|Plan a feature — produce SAM artifacts<br>without executing| Plan["/dh:add-new-feature {feature description}<br>Phases: discovery → codebase analysis →<br>architecture spec → task decomposition →<br>validation → context manifest<br>Output: feature slug + P{NNN} task plan"]

    Q1 -->|Execute an existing plan —<br>task plan already produced| Execute["/dh:implement-feature {plan path or slug}<br>Loops ready tasks, dispatches agents,<br>calls complete-implementation when all tasks COMPLETE"]

    Q1 -->|Work a single specific task<br>inside an existing plan| Single["/dh:start-task {plan path} --task {task-id}<br>Used by implement-feature per-task dispatch —<br>invoke directly to target one task"]

    Q1 -->|Run quality gates after<br>all tasks are COMPLETE| QG["/dh:complete-implementation {plan path|#N}<br>6-phase SAM path (with plan) or<br>3-phase proportional path (issue only):<br>code review → verification → integration →<br>doc drift → doc update → context refinement"]

    Q1 -->|Work a full milestone<br>in parallel isolated worktrees| Milestone["/dh:work-milestone<br>Wave-based parallel execution — each item<br>gets its own worktree. Use /dh:groom-milestone first."]
