What its author says it does

Copied from the file, not written here

Use when a repo has a legacy AIBOARDING.md (v1 layout) and should move to the standard AGENTS.md + CLAUDE.md layout with the .aiboarding/state.json sidecar. One-shot, preview-first migration that preserves the existing onboarding content and rewires the hooks.

Migrating AIBOARDING.md → AGENTS.md + CLAUDE.md

One-shot migration from the v1 custom-injection layout to the standard-files layout. The onboarding knowledge in AIBOARDING.md is an investment - carry it over; never regenerate from scratch and never delete anything without approval.

Announce at start: "Using migrate-aiboarding to move this repo to the AGENTS.md layout."

Precondition: AIBOARDING.md exists at the repo root. If it does not, stop and suggest create-agent-onboarding. If AGENTS.md also already exists, stop and ask the user which file is authoritative before writing anything.

Step 1: Carry over state

Read the AIBOARDING.md frontmatter (aiboarding_version, generated, last_synced_commit). These seed .aiboarding/state.json:

aiboarding_version: 2
generated: today's date
last_synced_commit: carried over verbatim (empty stays empty - the repair semantics of an empty pointer are preserved).

Step 2: Map the body

Map the three v1 H1 sections onto the v2 schema (see create-agent-onboarding's Shared contracts for the exact section list and order):

v1 source	v2 target sections
`# 1. Engineering Basics`	`Stack and Runtime`, `Build, Test, Run`, `Architecture Map`
`# 2. Domain & Business Logic`	`Project Purpose`, `Domain Model`
`# 3. AI-Specific Context`	`Agent Guardrails`, `Known Failure Modes`

Preserve the compressed density of the source text; split it, don't rewrite it. Backtick-quote any command, identifier, path, or error string that isn't already.

Two v2 sections have no v1 source: Verification Before Completion and Escalation - Ask the User When. Run a short, scoped grilling pass (the one-question-at-a-time style from create-agent-onboarding) ONLY for these gaps.

Step 3: Generate the wrapper and lifecycle files

Follow create-agent-onboarding Phase 6: CLAUDE.md (@AGENTS.md + fenced Claude-notes block), state.json, config.json, .aiboarding/.gitignore, the six hook files, and the three tools. Runtime awareness applies (hook/settings steps are Claude Code-only).

Step 4: Rewire hooks and settings (Claude Code runtimes)

In <repo>/.claude/settings.json:

Replace the SessionStart full-injection entry with the current template's entry (the modern session-start is a fallback warner, not an injector).
Delete the PreToolUse[Task] entry (pre-task is retired - SubagentStart is native now).
Replace the PostToolUse entry so it dispatches drift-check (not post-commit).
Add the SubagentStart and InstructionsLoaded entries from the template. Delete <repo>/.aiboarding/hooks/pre-task and <repo>/.aiboarding/hooks/post-commit. All edits idempotent: match aiboarding entries by command containing .aiboarding/hooks/run-hook.cmd; never duplicate; leave non-aiboarding hooks alone.

Step 5: Retire the legacy document

Ask the user to choose (default: archive):

Archive (default): move AIBOARDING.md to docs/archive/AIBOARDING.md unchanged. Git history preserves it either way; nothing at the root keeps stale onboarding discoverable by tools.
Keep as legacy: leave AIBOARDING.md in place and prepend a deprecation banner via inject-fenced AIBOARDING.md deprecation <banner-file> pointing to AGENTS.md. The drift hook keeps honoring the legacy layout only when state.json is absent, so with both present the sidecar wins. Never delete AIBOARDING.md outright unless the user explicitly asks.

Step 6: Single approval gate, then write

Before writing ANYTHING, present the full migration plan in one preview: every file to be created, modified (with the settings diff), moved, or deleted. One approval covers the whole batch; a rejection means nothing was touched.

Step 7: Exit check

Run create-agent-onboarding's Phase 7 validation gate, then audit-agent-onboarding if available. Report the file-by-file outcome, and remind the user to commit the new layout (the drift hook stays silent for onboarding-only commit ranges).
