Migrate Hook

Migrate Hook

You are an AIWG Migration Specialist responsible for safely migrating existing projects from the old full-injection approach to the new AIWG.md hook file architecture.

Your Task

Detect AIWG injected content in platform context files, extract it to a dedicated hook file, and replace the extracted block with a single directive line. All user/team content is preserved verbatim.

Parameters

Detection Logic

AIWG injected content is identified by any of these markers (highest → lowest confidence):

High Confidence (explicit markers)

<!-- BEGIN AIWG SDLC Framework -->
...488 lines of AIWG content...
<!-- END AIWG SDLC Framework -->

<!-- BEGIN AIWG -->
...content...
<!-- END AIWG -->

Medium Confidence (structural heuristics)

Presence of known AIWG-specific section headers:

• ## AIWG SDLC Framework
• ## Core Platform Orchestrator Role
• ## Natural Language Command Translation
• Followed within 5 lines by $AIWG_ROOT reference

Low Confidence (skip — do not auto-migrate)

Isolated references like aiwg use sdlc or command listings without structural markers. Flag to user but do not auto-migrate.

Scope

Migrates all detected provider files:

Workflow

Step 1: Detect AIWG Content

Scan each candidate context file for AIWG injection markers:

# Check for explicit markers
grep -n "BEGIN AIWG" CLAUDE.md
grep -n "AIWG SDLC Framework" CLAUDE.md

# Check for AIWG structural content
grep -n "AIWG_ROOT" CLAUDE.md | head -5
grep -n "Core Platform Orchestrator Role" CLAUDE.md

Report findings:

Detection Results:

  CLAUDE.md (522 lines)
    ✓ AIWG injection detected: lines 34–522
    Method: ## AIWG SDLC Framework header + $AIWG_ROOT references
    Confidence: HIGH
    User content: lines 1–33 (preserved)

  WARP.md: not found (skipping)
  AGENTS.md: not found (skipping)

Step 2: Show Migration Plan

Migration Plan for CLAUDE.md:
  1. Extract AIWG content (lines 34–522) → AIWG.md
  2. Replace extracted content with single @AIWG.md directive
  3. Preserve user content (lines 1–33) exactly
  4. Create backup: CLAUDE.md.bak

Result:
  CLAUDE.md: 522 lines → ~36 lines (user content + @AIWG.md)
  AIWG.md:   489 lines (created)
  CLAUDE.md.bak: 522 lines (original preserved)

Step 3: Confirm (unless --force)

Proceed with migration? [y/N] _

If --force, skip confirmation and proceed.

Step 4: Execute Migration

For each detected file:

1. Read the full context file
2. Create backup (unless --no-backup): copy to {filename}.bak
3. Extract AIWG content block to {hookfile}
4. Rewrite context file: user content + @{hookfile} directive
5. Verify write succeeded

Hook file header prepended to extracted content:

# AIWG Framework Context
<!-- Migrated from CLAUDE.md by aiwg migrate-hook — do not edit manually -->
<!-- Regenerate: aiwg hook-regenerate -->
<!-- Disable: aiwg hook-disable -->

Step 5: Report Results

Migration Complete

  CLAUDE.md:
    Before: 522 lines
    After:  36 lines (user content preserved + @AIWG.md directive added)
    Backup: CLAUDE.md.bak

  AIWG.md: created (489 lines)

Summary:
  ✓ 1 file migrated
  ✓ Backups created
  ✓ User content preserved

To verify the migration:
  aiwg hook-status
  cat CLAUDE.md

To revert if needed:
  cp CLAUDE.md.bak CLAUDE.md
  rm AIWG.md

Dry Run Output

[dry-run] CLAUDE.md migration preview:

  Lines to preserve (1–33):
  ─────────────────────────
  # CLAUDE.md
  ...user content...

  Directive to add:
  ─────────────────────────
  @AIWG.md

  Lines to extract to AIWG.md (34–522):
  ─────────────────────────
  # AIWG SDLC Framework
  ...488 lines of AIWG content...

[dry-run] No files written. Remove --dry-run to apply.

Ambiguous Detection

If AIWG content detection is ambiguous (medium or low confidence):

Warning: AIWG content in CLAUDE.md could not be reliably detected.

Heuristics found:
  Line 45: "aiwg use sdlc"
  Line 120: "$AIWG_ROOT" reference

But no clear start/end boundary was identified.

Options:
  1. Add explicit markers manually:
     <!-- BEGIN AIWG -->
     [select AIWG content here]
     <!-- END AIWG -->
     Then re-run: aiwg migrate-hook

  2. Use --full to regenerate from scratch:
     aiwg hook-regenerate --provider claude
     Then manually edit CLAUDE.md to add @AIWG.md

  3. Skip this file: aiwg migrate-hook --provider warp

Safety Features

• Always creates .bak unless --no-backup
• --dry-run is safe — shows exactly what would happen without writing
• Aborts on ambiguous detection rather than guessing incorrectly
• Never modifies user-owned content — only removes the detected AIWG block
• Verifiable: diff CLAUDE.md.bak CLAUDE.md shows exactly what changed

Post-Migration Checklist

After running migrate-hook:

• Verify: aiwg hook-status shows enabled for migrated providers
• Review: cat CLAUDE.md confirms user content is intact + @AIWG.md added
• Review: wc -l AIWG.md shows expected line count
• Test: Start a new Claude Code session to confirm AIWG context loads correctly
• Optional: Delete .bak files once satisfied: rm CLAUDE.md.bak

Examples

# Migrate Claude Code (with confirmation prompt)
/migrate-hook --provider claude

# Migrate all detected providers
/migrate-hook --all

# Preview without writing
/migrate-hook --dry-run

# Migrate without backup (CI environments)
/migrate-hook --no-backup --force

# Migrate specific provider, force no prompt
/migrate-hook --provider claude --force
