Claude Code Handoff
The principle: never auto-invoke Claude
Claude Max quota is finite. Auto-invoking on every hard task burns it unnecessarily and removes user control. This skill ALWAYS produces a file and notifies the user — it never calls the Claude API directly.
The user reviews the handoff, decides if they want to spend quota on it, then runs Claude Code themselves. This is the contract.

# Handoff: Add SwiftData + CloudKit migration for iOS 26
## Original request
[verbatim user request]
## Why this is being handed off
**Reason**: iOS domain hard gate
Local M2.7 JANGTQ-CRACK's Swift training data is stale on SwiftData + CloudKit
migrations for iOS 26. This is a case where Claude Sonnet 4.6's more recent
training plus 1M context beats retrieved RAG snippets.
## Context gathered locally
### Files read
- `App/AppDelegate.swift` (112 lines)
- `Models/User.swift` (48 lines)
- `Models/UserDataSource.swift` (204 lines)
- `Views/ContentView.swift` (89 lines)
### Codebase patterns identified
- Project uses SwiftData with `@Model` macro
- Existing SwiftData stack in `Models/UserDataSource.swift:42`
- No CloudKit integration yet
- Deployment target: iOS 18, need to upgrade to iOS 26 first
### Relevant Apple documentation retrieved
1. [SwiftData CloudKit integration guide (iOS 26)](ref-link)
2. [iOS 26 migration patterns for SwiftData](ref-link)
3. [CloudKit schema synchronization](ref-link)
### Related Stack Overflow patterns
[if any]
## Proposed approach (from local planning)
Sub-problems identified:
1. **Update deployment target to iOS 26** (AppDelegate, Info.plist)
2. **Add CloudKit entitlement** (project settings)
3. **Migrate UserDataSource to use CloudKit-backed ModelContainer**
- Depends on sub-problem 1
4. **Add migration plan for existing local data**
- Depends on sub-problem 3
5. **Update Views to handle CloudKit sync state**
- Depends on sub-problem 3
APIs involved:
- `ModelConfiguration(cloudKitDatabase:)` — iOS 26+
- `CKContainer.applicationDefault()` — iOS 8+
- `SchemaMigrationPlan` — iOS 26+
Risks:
- HIGH: Existing local user data could be lost if migration not handled
- MEDIUM: CloudKit development vs production environment confusion
- LOW: iOS version compatibility for existing users on < 26
## What local attempted and failed
[if build_failed]
Generated code that attempted the migration. Compile errors:
- Error 1: `cannot find 'cloudKitDatabase' in scope at ModelConfiguration.swift:12`
(Fixed in iteration 2 — was missing import)
- Error 2: `'SchemaMigrationPlan' is only available in iOS 26.0 or newer`
(Unable to fix — need guidance on availability strategy)
## Suggested Claude Code prompt
Copy-paste this into Claude Code:
Read /Users/stephen/projects/myapp/.openclaw-skills/handoffs/2026-04-21T14:32:18Z-add-swiftdata-cloudkit-migration.md
Then implement the 5 sub-problems in order. You have write access to the
project. Run swift build after each sub-problem to verify.
When done, produce a summary of what changed and any remaining concerns.
Or run from terminal:
```bash
cd /Users/stephen/projects/myapp
claude "Read .openclaw-skills/handoffs/2026-04-21T14:32:18Z-add-swiftdata-cloudkit-migration.md and implement the plan"
Estimated Claude quota cost
Based on context size: ~12K input tokens + ~8K output = ~20K tokens. Sonnet 4.6: ~20K × $3/$15 per MTok = ~$0.15 in direct API equivalent. Via Max plan: draws modestly from your daily quota.

## Integration with other skills
- Invoked by `coding-orchestrator` at multiple points (hard gate, after
failed build, after failed reflection)
- Reads context from `task.scratchpad` populated by earlier steps
- Writes to project's `.openclaw-skills/handoffs/` directory
- Adds entry to global handoff log at `~/.openclaw-skills/handoff-log.sqlite`
## Handoff log for analytics
Every handoff gets logged to SQLite:
```sql
CREATE TABLE handoff_log (
id INTEGER PRIMARY KEY,
timestamp TEXT NOT NULL,
task_slug TEXT NOT NULL,
reason TEXT NOT NULL,
project_root TEXT,
estimated_tokens INTEGER,
user_ran_claude BOOLEAN, -- updated when user runs claude
claude_succeeded BOOLEAN, -- updated manually or via claude output log
notes TEXT
);
Query this log periodically to understand your escalation patterns:
- Which reasons are most common? (if "build_failed" dominates, improve your iOS system prompt or RAG)
- How often do handoffs actually get run? (if low, your escalation threshold is too aggressive)
- How often does Claude Code succeed? (if it fails too, the task genuinely needs architectural input from you)
What handoff does NOT do
- Does not execute Claude Code
- Does not read your Claude Max quota
- Does not cache or share handoffs between users
- Does not modify source code (only writes to
.openclaw-skills/handoffs/)
These are all explicit user actions. The skill's job is to prepare the best possible brief and then step aside.
