v0.10.3

v0.10.3 — Claude Fable 5

Features

• Claude Fable 5 is here — Anthropic's most capable widely released model (GA 2026-06-09) is now available in Craft Agent on the Claude Agent SDK path, with a full 1M-token context window. It works across direct Anthropic connections and AWS Bedrock (us/eu/global inference-profile variants), with the model description localized in all 7 languages. Opus 4.8 remains the default — Fable is offered alongside it, not in front of it — and it is added to the Pi → Anthropic auth-bridge preferences below Opus. Because Fable 5 (and the Mythos 5 class) run with adaptive thinking always on and reject an explicit disabled thinking option, the thinking resolver now maps the "off" and minimize-thinking cases to low-effort adaptive thinking for these models; Opus, Sonnet, and Haiku behavior is byte-for-byte unchanged.

Improvements

• Claude Agent SDK uplifted to 0.3.170 — @anthropic-ai/claude-agent-sdk moves from 0.3.154 → 0.3.170 (root plus the core and shared peer dependencies, lockfile refreshed). No API breakage; the full typecheck passes clean. (22c7ae99)
