Added an \"Organization policy\" line to `/status` and `claude doctor` that says why your organization's policy could not be loaded, such as a proxy not passing the endpoint through - Added `bashOutputMaxChars` and `taskOutputMaxChars` settings to raise how much command and background-task output Claude receives inline before it is saved to a file, up to 128K characters - Added `--append-subagent-system-prompt-file` to read the subagent system prompt from a file, for prompts too large to pass on the command line - Added `/skill-doctor` to show which loaded skills go unused and what they cost in context, so you can prune them - Fixed typed or pasted characters occasionally landing out of order or being dropped during fast input or key repeat - Fixed `/add-dir ` printing a false \"couldn't be resolved\" error when the working directory is on a `/net` automount - Fixed the Bedrock setup wizard hanging when AWS or an AWS credential helper never responds (it now times out with a clear error), and its model checks failing behind a TLS-inspecting proxy -..."},"evidence_pages":[],"related_signals":[{"id":"6767a27d-298c-47b1-8484-2a088041be49","url":"https://onlylabs.fyi/signals/6767a27d-298c-47b1-8484-2a088041be49","source_url":"https://github.com/anthropics/claude-code-action/releases/tag/v1.0.219","title":"anthropics/claude-code-action v1.0.219","context":"anthropics/claude-code-action","kind":{"key":"release","label":"Release"},"org":{"slug":"anthropic","name":"Anthropic","category":"frontier-lab"},"occurred_at":"2026-09-08T23:57:14+00:00","first_seen_at":"2026-09-09T07:00:41.590485+00:00","date_source":"source"},{"id":"6be57f94-a397-47ea-b5d8-911175715079","url":"https://onlylabs.fyi/signals/6be57f94-a397-47ea-b5d8-911175715079","source_url":"https://github.com/anthropics/claude-agent-sdk-typescript/releases/tag/v0.3.266","title":"anthropics/claude-agent-sdk-typescript v0.3.266","context":"anthropics/claude-agent-sdk-typescript","kind":{"key":"release","label":"Release"},"org":{"slug":"anthropic","name":"Anthropic","category":"frontier-lab"},"occurred_at":"2026-09-08T23:55:30+00:00","first_seen_at":"2026-09-09T07:00:41.590485+00:00","date_source":"source"},{"id":"86612c85-a7c9-4b8a-b61f-49d5f939ea36","url":"https://onlylabs.fyi/signals/86612c85-a7c9-4b8a-b61f-49d5f939ea36","source_url":"https://github.com/anthropics/claude-code/releases/tag/v2.1.266","title":"anthropics/claude-code v2.1.266","context":"anthropics/claude-code","kind":{"key":"release","label":"Release"},"org":{"slug":"anthropic","name":"Anthropic","category":"frontier-lab"},"occurred_at":"2026-09-08T23:55:14+00:00","first_seen_at":"2026-09-09T07:00:41.590485+00:00","date_source":"source"},{"id":"44bc9997-63ba-4696-ad9c-695403d5a6e2","url":"https://onlylabs.fyi/signals/44bc9997-63ba-4696-ad9c-695403d5a6e2","source_url":"https://github.com/anthropics/claude-code-action/releases/tag/v1.0.218","title":"anthropics/claude-code-action v1.0.218","context":"anthropics/claude-code-action","kind":{"key":"release","label":"Release"},"org":{"slug":"anthropic","name":"Anthropic","category":"frontier-lab"},"occurred_at":"2026-09-08T20:39:25+00:00","first_seen_at":"2026-09-09T07:00:41.590485+00:00","date_source":"source"},{"id":"64a4ff2e-0089-4497-ae20-6eee0a6307d8","url":"https://onlylabs.fyi/signals/64a4ff2e-0089-4497-ae20-6eee0a6307d8","source_url":"https://github.com/anthropics/claude-agent-sdk-typescript/releases/tag/v0.3.265","title":"anthropics/claude-agent-sdk-typescript v0.3.265","context":"anthropics/claude-agent-sdk-typescript","kind":{"key":"release","label":"Release"},"org":{"slug":"anthropic","name":"Anthropic","category":"frontier-lab"},"occurred_at":"2026-09-08T20:37:33+00:00","first_seen_at":"2026-09-09T07:00:41.590485+00:00","date_source":"source"},{"id":"aa1bcca4-e3bf-4e5f-8977-fe7b4d684a77","url":"https://onlylabs.fyi/signals/aa1bcca4-e3bf-4e5f-8977-fe7b4d684a77","source_url":"https://github.com/anthropics/claude-code/releases/tag/v2.1.265","title":"anthropics/claude-code v2.1.265","context":"anthropics/claude-code","kind":{"key":"release","label":"Release"},"org":{"slug":"anthropic","name":"Anthropic","category":"frontier-lab"},"occurred_at":"2026-09-08T20:37:31+00:00","first_seen_at":"2026-09-09T07:00:41.590485+00:00","date_source":"source"}]}
