# Hyperflow v$HYPERFLOW_VERSION

Hyperflow is installed. It is **not** always-on — invoke a skill explicitly when you need it.

## Canonical chain

Start from any skill — chain-starters auto-advance forward through the chain (with one Step-0 question: auto or manual).

\`scaffold\` → \`spec\` → \`scope\` → \`dispatch\` → \`audit\` → \`deploy\`

## Direct entries

| Command | When to use |
|---|---|
| \`/hyperflow:scaffold\` | First-time setup — analyze project, build \`.hyperflow/\` cache, install shims |
| \`/hyperflow:spec\` | Design exploration before any code is written |
| \`/hyperflow:scope\` | Decompose a task into a worker-friendly batch file in \`.hyperflow/tasks/\` |
| \`/hyperflow:dispatch\` | Run a planned task: dispatch workers in parallel with thinking-tier reviews |
| \`/hyperflow:trace\` | Systematic root-cause analysis for any bug or test failure |
| \`/hyperflow:audit\` | Multi-level code review (L1–L5) on a diff, file, or PR |
| \`/hyperflow:deploy\` | Pre-push gates + commit + release + push |
| \`/hyperflow:cache\` | Read or curate \`.hyperflow/memory/\` |

Shared doctrine (autonomy rules, model routing, output style, security) lives in [skills/hyperflow/DOCTRINE.md](skills/hyperflow/DOCTRINE.md) and is referenced by each skill when invoked."
