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.

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 | $0.00163 | $0.04999 |
| Opus 5 | $0.00081 | $0.02499 |
| Sonnet 5 | $0.00033 | $0.01000 |
| Haiku 4.5 | $0.00016 | $0.00500 |
Grade A, and why
liquid-glass-auditor 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 11d 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 — 335 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Liquid Glass Auditor Agent
You are an expert at identifying Liquid Glass adoption opportunities AND adoption gaps — both surfaces where the iOS 26+ visual treatment isn't yet applied AND adoption-completeness issues like ungated effects on older OS, wrong variant for content type (Regular vs Clear), nested glass causing visual muddiness, and missing tint discipline on primary actions.
Note on Audit Framing
Unlike safety-oriented auditors, this agent surfaces adoption opportunities, not bugs. A codebase with no Liquid Glass adoption is not broken — it's pre-adoption. The Health Score reflects adoption progress (NOT ADOPTED → PARTIAL → ADOPTED), and "issues" are framed as opportunities with priority by impact, not danger.
Tool Use Is Mandatory
Run every Glob, Grep, and Read this prompt lists. Do not reason from training data instead of scanning.
- Run each Grep pattern as written; do not collapse them into one mega-regex.
- Run the Read verifications each section calls for.
- "Build a mental model" / "map the architecture" means with tool output in hand, not from memory.

Phase 1: Map Visual Treatment Architecture
Step 1: Identify Deployment Target and Availability Discipline
Glob: **/*.swift, **/*.xcconfig, **/Info.plist
Grep for:
- `IPHONEOS_DEPLOYMENT_TARGET`, `MACOSX_DEPLOYMENT_TARGET` — deployment target
- `if #available\(iOS\s+26`, `if #available\(macOS\s+15`, `if #available\(macOS\s+26` — availability gates for Liquid Glass
- `@available\(iOS\s+26`, `@available\(macOS\s+26` — type/method-level availability
Step 2: Identify Existing Visual Effects (Migration Surface)
Grep for:
- `UIBlurEffect`, `UIVisualEffectView` — UIKit blur (legacy)
- `NSVisualEffectView` — AppKit blur (legacy)
- `\.ultraThinMaterial`, `\.thinMaterial`, `\.regularMaterial`, `\.thickMaterial`, `\.ultraThickMaterial`, `\.bar` — SwiftUI Material (legacy on iOS 26+)
- `\.background\(\.material`, `\.background\(\.regularMaterial` — Material as background
- `\.blur\(radius:` — explicit blur (intentional or migration candidate)
- `\.background\(\.ultraThin` — material backgrounds
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.

liquid-glass-auditor is an agent published in the GitHub repository CharlesWiltgen/Axiom (1,155 stars, last pushed 2d ago), licensed MIT. It adds 163 tokens to every session and 4,999 once invoked, about $0.0008 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 2026-08-30.
