The Python agent SDK now rejects malformed skill names that could silently disable tools, while the code action fixes inconsistent timestamp handling across GitHub event types.

Claude Agent SDK v0.2.129 ships a breaking change that validates skill names before they reach the CLI [1]. Names containing parentheses, commas, control characters, wildcards, or leading slashes now raise ValueError at connect time, closing a gap where malformed names could build rules that never match [2]. This lands alongside Claude Code v2.1.221, which adds a Focus view toggle to hide tool activity behind per-turn summaries [4]. On the automation side, claude-code-action now derives trigger timestamps for issues and pull_request events, ensuring comment and review filtering behaves consistently regardless of what triggered the run [3]. The CLI and plugin ecosystem are synchronized across all three releases, with knowledge-work-plugins rolling out five automated SHA bumps that passed validation before opening for review [5], [6], [7], [8], [9].
