CharlesWiltgen/Axiom v27.5.0

Release v27.5.0

on GitHub

Released October 13, 2026

New

• Support for claude.ai and the Claude Desktop app – Axiom can now be installed from either, and there’s a new guide to walk users through it.
• Core ML and Speech – The axiom-ai skill suite now includes four new skills:
  • coreml-deployment – Loading, caching and running models safely under Swift 6
  • coreml-ref – The Core ML API reference
  • coreml-diag – Load errors, slow predictions, memory growth and accuracy lost to compression
  • speech – File and live transcription with SpeechAnalyzer

Updated

• Accessibility – Accessibility guidance now rests on Accessibility Nutrition Labels (declare a feature only when every common task works with it), legal obligations, and the people who rely on it.
• Touch targets – Follow the HIG: a 44×44 pt hit region (60 pt on visionOS) and a 28×28 pt minimum control size.
• Foundation Models freezes – Traces a freeze to synchronous main-actor work around generation, since awaiting a session suspends rather than blocks. It also covers isResponding and concurrent requests on one session, which foundation-models-auditor now flags.
• App Store Connect triage – Better catalogs what the App Store Connect API provides: TestFlight crash reports, plus hang, launch and disk-write diagnostics for App Store builds. The change covers app-store-connect-ref, testflight-triage, production-triage and triage-analyzer.
• asc-mcp – Updated coverage for asc-mcp 4.1.6: 502 tools across 35 workers, snake_case parameters, worker presets, the confirmations destructive calls require, retry and read-only behavior, and TestFlight feedback with include_pii.
• App Store screenshot sizes – Updated to follow Apple’s current display classes.
• Also updated – Core Location availability on all five platforms, which SwiftUI navigation failures SwiftUI logs, CarPlay simulation under Xcode 27, Apple-docs lookups through the SDK’s Swift interfaces and headers, and smaller updates in GRDB, CryptoKit, SpriteKit, RealityKit, Network framework, MapKit, watchOS and Instruments templates.

Fixed

• MCP server – In development mode, the server process now exits when its client disconnects.
• Pi – Sessions now list xcproject with the other bundled tools, so the assistant knows it’s available.
• Cursor – Generated build and test instructions now find axbuild before running it.

Changed

• Bundled tools – Moved from bin/ to tools/ in the plugin, which lets Axiom install from claude.ai and the Claude Desktop app.
• Documentation – Adds pages for Speech, Foundation Models guardrails and the Core ML skills, including conversion, compression and training. The storage, asc-mcp and xcsym pages each merge into one, with their old addresses redirecting.
