Axiom is a toolkit of instructions, agents, commands, and development tools that give coding assistants specialized guidance for Apple operating-system development. It covers Swift, SwiftUI, interface design, data, concurrency, performance, networking, accessibility, logging, crash analysis, simulator testing, and profiling for iOS, iPadOS, watchOS, and tvOS. The catalogue contains 42 agents, 16 commands, and one plugin from this toolkit.
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.

What it costs to keep this loaded
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 | $0.00048 | $0.05650 |
| Opus 5 | $0.00024 | $0.02825 |
| Sonnet 5 | $0.00010 | $0.01130 |
| Haiku 4.5 | $0.00005 | $0.00565 |
Grade A, and why
axiom-shipping 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 6d 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 — 478 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Shipping & App Store
You MUST use this skill when preparing to submit ANY app, handling App Store rejections, or working on release workflow.
Not on Claude Code? Where this router says "Launch
some-auditoragent", read that auditor's file in this suite and follow it inline — the same procedure, needing only file search and read.Homed in another suite:
axiom-integration/skills/iap-auditor.md,axiom-security/skills/security-privacy-scanner.md.Agents that need Bash — builds, tests, simulators, crash symbolication — stay Claude Code-only; there is no inline equivalent for those.
When to Use
Use this skill when you encounter:
- Preparing an app for App Store submission
- App Store rejection (any guideline)
- Metadata requirements (screenshots, descriptions, keywords)
- Privacy manifest and nutrition label questions
- Age rating and content classification
- Export compliance and encryption declarations
- EU DSA trader status
- Account deletion or Sign in with Apple requirements
- Build upload and processing issues
- App Review appeals
- WWDC25/WWDC26 App Store Connect changes
- First-time submission workflow

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.
- 6d ago First seen · 478 lines · 48 tokens per session scan A c88010e8aa51
axiom-shipping is a skill published in the GitHub repository CharlesWiltgen/Axiom (1,155 stars, last pushed 3d ago), licensed MIT. It adds 48 tokens to every session and 5,650 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 2026-09-06.
