Claude Code v2.1.221-v2.1.226 cluster repo
Claude Code shipped five releases (v2.1.221 through v2.1.226, Aug 4-8 2026) as a tight cluster. Headline features across the cluster: (1) self-hosted runner beta — register your own machine or container as a Claude Code runner for Team and Enterprise plan sessions; (2) archive plugin source — install plugins from an HTTPS zip with optional SHA-256 pinning, no git or npm registry required; (3) workspace trust for agents — agent CLAUDE.md hooks in untrusted directories now require the agent file folder to have accepted workspace trust before running; (4) gateway spend-limit display — the limit-reached error now names the cap, reset time, and operator message; (5) cross-session messaging settings (crossSessionInbound and dialogExpiry) for multi-agent conversations; (6) 401 fix — the transient 401 that appeared when a long-lived CLAUDE_CODE_OAUTH_TOKEN was replaced by a stored login short-lived token no longer kills headless sessions.
What it does for you: The 401 headless-session fix in v2.1.225 directly resolves the intermittent auth error YY hits when the Axion Telegram bridge restarts — the same symptom that previously required a manual bridge restart to clear. The self-hosted runner converts YY's Windows machine into a registered Claude Code runner, meaning Team or Enterprise web and mobile sessions can spawn on this box instead of Anthropic cloud — the exact pattern Hermes already implements manually. Archive plugin source with SHA-256 pinning gives a reproducible, git-free way to ship Axion skills as versioned zip files to the runner. Upgrade is one CLI command: npm update -g @anthropic-ai/claude-code.
In practice: runtime-cluster-critical-fixes-and-infra
For: Claude (Axion). Claude Code CLI itself — the runtime Axion and the Telegram bridge sit on.
Verdict: build now. The 401 headless-session fix resolves a documented Axion bridge symptom; self-hosted runner formalizes what Hermes does manually; archive plugin source enables versioned skill distribution; upgrade is one command.
