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 | $0.00042 | $0.02019 |
| Opus 5 | $0.00021 | $0.01009 |
| Sonnet 5 | $0.00008 | $0.00404 |
| Haiku 4.5 | $0.00004 | $0.00202 |
Grade A, and why
axiom-sqlitedata-migration scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Migrating from SwiftData to SQLiteData
When to Switch
┌─────────────────────────────────────────────────────────┐
│ Should I switch from SwiftData to SQLiteData? │
├─────────────────────────────────────────────────────────┤
│ │
│ Performance problems with 10k+ records? │
│ YES → SQLiteData (10-50x faster for large datasets) │
│ │
│ Need CloudKit record SHARING (not just sync)? │
│ YES → SQLiteData (SwiftData cannot share records) │
│ │
│ Complex queries across multiple tables? │
│ YES → SQLiteData + raw GRDB when needed │
│ │
│ Need Sendable models for Swift 6 concurrency? │
│ YES → SQLiteData (value types, not classes) │
│ │
│ Testing @Model classes is painful? │
│ YES → SQLiteData (pure structs, easy to mock) │
│ │
│ Happy with SwiftData for simple CRUD? │
│ YES → Stay with SwiftData (simpler for basic apps) │
│ │
└─────────────────────────────────────────────────────────┘
Pattern Equivalents

@Query var items: [Item] |
@FetchAll var items: [Item] |
@Query(sort: \.title) |
@FetchAll(Item.order(by: \.title)) |
@Query(filter: #Predicate { $0.isActive }) |
@FetchAll(Item.where(\.isActive)) |
@Environment(\.modelContext) |
@Dependency(\.defaultDatabase) |
context.insert(item) |
Item.insert { Item.Draft(...) }.execute(db) |
context.delete(item) |
Item.find(id).delete().execute(db) |

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-sqlitedata-migration is a skill published in the GitHub repository ComeOnOliver/skillshub (63 stars, last pushed 2mo ago), licensed MIT. It adds 42 tokens to every session and 2,019 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
