Pattern: Agent CLIs Are Converging on an Identical Set of Session-Control Verbs

GitHub Changelog / Claude Code Docs / Antigravity Changelog·medium signalXBlueskyLinkedInCopy link

Within a week, Copilot CLI shipped `/tasks`, `/rewind`, prompt queueing, and `/app` context handoff; Claude Code already has `/rewind`, `/fork`, agent view, and cross-session messaging; Antigravity CLI retains Agent Skills, Hooks, Subagents, and plugins after its migration from Gemini CLI. The verbs — rewind, fork, hand off, manage subagents, queue input mid-turn — are now table stakes rather than differentiators. The differentiation has moved to what's underneath: cache behavior on fork, whether rewind touches git, and how far context survives a handoff.
