vibe-sync

name	vibe-sync
description	Sync vibe-doctor harness/template updates while preserving project-owned code and rules.

/vibe-sync updates harness-owned files from upstream according to .vibe/sync-manifest.json. It must preserve project-owned source, product context, local provider settings, and PROJECT:* marker blocks.

When To Run

• Session start or statusline reports that a harness update is available.
• The user explicitly asks for /vibe-sync or npm run vibe:sync.
• Preflight reports a harness version mismatch.

Flow

1. Run npm run vibe:sync -- --dry-run and inspect the plan.
2. Explain any conflict rows to the user unless they already authorized forceful sync.
3. Run npm run vibe:sync.
4. Let post-sync verification run:
   • harness-only typecheck via .vibe/harness/tsconfig.harness.json
   • bootstrap preflight via .vibe/harness/scripts/vibe-preflight.mjs --bootstrap
5. If sync fails, use .vibe/sync-backup/<timestamp>/ for recovery context.

Options

Flag	Purpose
--dry-run	Print the plan only.
--force	Replace all conflicted harness files with upstream versions.
--from <path>	Use a local upstream checkout instead of cloning.
--ref <tag>	Override the upstream git ref for this run.
--no-backup	Skip backup creation.
--no-verify	Skip post-sync typecheck/preflight.
--json	Print the plan as JSON.

Legacy Bootstrap

For old projects that cannot run the normal sync path yet, run the standalone bootstrap once from the project root. It understands current glob-based manifests and copies .vibe/harness/** before normal /vibe-sync is available.

Local clone:

git clone --depth 1 https://github.com/mir3626/vibe-doctor /tmp/vibe-doctor
node /tmp/vibe-doctor/.vibe/harness/scripts/vibe-sync-bootstrap.mjs

Compatibility raw URL, kept for legacy docs:

curl -sL https://raw.githubusercontent.com/mir3626/vibe-doctor/main/scripts/vibe-sync-bootstrap.mjs | node --input-type=module -

The root scripts/vibe-sync-bootstrap.mjs file is only a compatibility bridge. The canonical harness runtime lives under .vibe/harness/**.

Upstream Ref Contract

• exact vX.Y.Z or X.Y.Z: hard pin
• caret ^vX.Y.Z or ^X.Y.Z: floating compatible range
• branch names such as main: use as-is
• missing upstream.ref: use cached latest when newer than installed, then current harnessVersion, then main

Default templates use caret refs so plain /vibe-sync advances to the latest compatible harness version. Use exact refs only when an intentional pin is needed.

Boundaries

• Root src/**, scripts/**, test/**, app/**, components/**, and lib/** are project-owned after v1.7.0.
• Harness runtime, tests, migrations, and configs live under .vibe/harness/**.
• Root Markdown files stay hybrid through marker blocks.
• package.json sync owns scripts.vibe:* and engines; product scripts such as test, build, typecheck, and test:ui are project-owned.
