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 | $0.00068 | $0.04275 |
| Opus 5 | $0.00034 | $0.02138 |
| Sonnet 5 | $0.00014 | $0.00855 |
| Haiku 4.5 | $0.00007 | $0.00428 |
Grade A, and why
axiom-storage 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.

iOS Storage Guide
Purpose: Navigation hub for ALL storage decisions — database vs files, local vs cloud, specific locations iOS Version: iOS 17+ (iOS 26+ for latest features) Context: Complete storage decision framework integrating SwiftData (WWDC 2023), CKSyncEngine (WWDC 2023), and file management best practices
When to Use This Skill
✅ Use this skill when:
- Starting a new project and choosing storage approach
- Asking "where should I store this data?"
- Deciding between SwiftData, Core Data, SQLite, or files
- Choosing between CloudKit and iCloud Drive for sync
- Determining Documents vs Caches vs Application Support
- Planning data architecture for offline/online scenarios
- Migrating from one storage solution to another
- Debugging "files disappeared" or "data not syncing"
❌ Do NOT use this skill for:
- SwiftData implementation details (use
axiom-swiftdataskill) - SQLite/GRDB specifics (use
axiom-sqlitedataoraxiom-grdbskills) - CloudKit sync implementation (use
axiom-cloudkit-refskill) - File protection APIs (use
axiom-file-protection-refskill)

Core Philosophy
"Choose the right tool for your data shape. Then choose the right location."
Storage decisions have two dimensions:
- Format: How is data structured? (Queryable records vs files)
- Location: Where is it stored? (Local vs cloud, which directory)
Getting the format wrong forces workarounds. Getting the location wrong causes data loss or backup bloat.
The Complete Decision Tree
Level 1: Format — What Are You Storing?
What is the shape of your data?
├─ STRUCTURED DATA (queryable records, relationships, search)
│ Examples: User profiles, task lists, notes, contacts, transactions
│ → Continue to "Structured Data Path" below
│
└─ FILES (documents, images, videos, downloads, caches)
Examples: Photos, PDFs, downloaded content, thumbnails, temp files
→ Continue to "File Storage Path" below
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-storage is a skill published in the GitHub repository ComeOnOliver/skillshub (63 stars, last pushed 2mo ago), licensed MIT. It adds 68 tokens to every session and 4,275 once invoked, about $0.0003 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.
