9<Update label="2.1.294" description="October 8, 2026">
10 * Fixed `prompt` and `agent` hooks written as instructions (such as "Block commands that...") allowing what they should block
11 * Improved how `prompt` hooks on Stop and SubagentStop written as instructions (such as "Carry on if the build is broken") are judged, so Claude is less likely to stop early

1015 * Added Claude Haiku 5.5 (`claude-haiku-5-5`), now the default Haiku model on the Anthropic API — 1M context, $0.10/$0.50 per Mtok ($0.50/$2.50 for prompts over 100K)
1116 * Added `agentType` to the `subagentStatusLine` payload, so scripts can tell custom subagent types apart

17461751 * Improved `/autofix-pr`: when `gh pr view` fails it now shows gh's own error (sign-in, SAML, rate limit) instead of a generic exit-code line
17471752 * Improved `/autofix-pr` to say why GitHub webhook delivery couldn't be set up for the PR (for example, no linked GitHub account) instead of a generic warning
17481753 * Improved `/web-setup` errors: a refused GitHub token now lists the likely reasons and the fix, and a connection failure names a configured proxy or TLS certificate problem
1749 * Improved the in-session SSL certificate and proxy connection errors to name the error code and what to fix, such as `NODE_EXTRA_CA_CERTS` for an untrusted corporate CA
1750 * Improved the error when a cloud session can't be created because your Claude login expired or was revoked: it now tells you to run `/login`
1751 * Improved the error shown when an MCP server's sign-in expires mid-session to say how to re-authentic
1754 * Improved the in-session SSL certificate and pr
