+## Summary
+
+- Updates \`claude-agent-sdk\` minimum version from \`>=${CURRENT}\` to \`>=${LATEST}\`
+- Files changed: \`pyproject.toml\` and \`uv.lock\`
+
+## Release Info
+
+PyPI: https://pypi.org/project/claude-agent-sdk/${LATEST}/
+
+## Test Plan
+
+- [ ] Runner tests pass (\`runner-tests\` workflow)
+- [ ] Container image builds successfully (\`components-build-deploy\` workflow)
+
+> **Note:** PRs created by \`GITHUB_TOKEN\` do not automatically trigger \`pull_request\` workflows.
+> CI must be triggered manually (push an empty commit or re-run workflows) or the repo can be
+> configured with a PAT via \`secrets.BOT_TOKEN\` to enable automatic CI triggering.
