tengu_pale_kestrel ◇ Permission prompts for inline shell commands such as bash -c now depend on whether the command contains rm or rmdirv2.1.299 → v2.1.308 ◆in the build AND v2.1.299

origin to tell whether a plugin's own tool call was rewritten by another hookv2.1.300 → v2.1.308 ◆in the build AND v2.1.300 tengu_plain_sorrel ◇ When checking a shell command before running it, Claude Code now handles assignment-style arguments to dd under a separate rulev2.1.307 → v2.1.308 ◆in the build AND v2.1.307 tengu_playful_hare ◇ /recap now refuses requests relayed from Slack, Teams,

marketplace refreshes report skipped built-in marketplaces separatelyv2.1.138 or earlier → v2.1.308 ◆in the build AND v2.1.290 tengu_polished_tulip ◇ The git and commit instructions Claude receives can now include an extra line about checks before shipping, depending on which skills are loadedv2.1.286 → v2.1.308 ◆in the build AND v2.1.296 tengu_print_ceiling_stop_agents ◇ Behind a flag, exceeding the print-mode background wait ceiling can also stop the running agents, not just report them.v2.1.257 → v2.1.308 ◆in the build AND v2.1.295 tengu_proactivity_selector ◇ A --proactivity flag
