Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00038 | $0.02765 |
| Opus 5 | $0.00019 | $0.01383 |
| Sonnet 5 | $0.00008 | $0.00553 |
| Haiku 4.5 | $0.00004 | $0.00277 |
Grade A, and why
axiom-cloud-sync scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 404 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cloud Sync
Overview
Core principle: Choose the right sync technology for the data shape, then implement offline-first patterns that handle network failures gracefully.
Two fundamentally different sync approaches:
- CloudKit — Structured data (records with fields and relationships)
- iCloud Drive — File-based data (documents, images, any file format)
Quick Decision Tree
What needs syncing?
├─ Structured data (records, relationships)?
│ ├─ Using SwiftData? → SwiftData + CloudKit (easiest, iOS 17+)
│ ├─ Need shared/public database? → CKSyncEngine or raw CloudKit
│ └─ Custom persistence (GRDB, SQLite)? → CKSyncEngine (iOS 17+)
│
├─ Documents/files users expect in Files app?
│ └─ iCloud Drive (UIDocument or FileManager)
│
├─ Large binary blobs (images, videos)?
│ ├─ Associated with structured data? → CKAsset in CloudKit
│ └─ Standalone files? → iCloud Drive
│
└─ App settings/preferences?
└─ NSUbiquitousKeyValueStore (simple key-value, 1MB limit)
CloudKit vs iCloud Drive
| Aspect | CloudKit | iCloud Drive |
|---|---|---|
| Data shape | Structured records | Files/documents |
| Query support | Full query language | Filename only |
| Relationships | Native support | None (manual) |
| Conflict resolution | Record-level | File-level |
| User visibility | Hidden from user | Visible in Files app |
| Sharing | Record/database sharing | File sharing |
| Offline | Local cache required | Automatic download |
Red Flags
If ANY of these appear, STOP and reconsider:
- ❌ "Store JSON files in CloudKit" — Wrong tool. Use iCloud Drive for files
- ❌ "Build relationships manually in iCloud Drive" — Wrong tool. Use CloudKit
- ❌ "Assume sync is instant" — Network fails. Design offline-first
- ❌ "Skip conflict handling" — Conflicts WILL happen on multiple devices
- ❌ "Use CloudKit for user documents" — Users can't see them. Use iCloud Drive
- ❌ "Sync on app launch only" — Users expect continuous sync
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

axiom-cloud-sync is a skill published in the GitHub repository ComeOnOliver/skillshub (63 stars, last pushed 2mo ago), licensed MIT. It adds 38 tokens to every session and 2,765 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
