Goose moved to the Linux Foundation, OpenCode relocated to the anomalyco org and now cites 160K+ stars, 900+ contributors, and 7.5M monthly developers (Morph). On capability, Codex CLI with GPT-5.5 still leads Terminal-Bench at 83.4%, while Google retired the consumer Gemini CLI (access ended June 18) and folded it into the Antigravity platform. The open-source tier is stabilizing around a few governed harnesses rather than fragmenting further, which is good news if you've been afraid to bet on a CLI agent that might get abandoned.

June head-to-heads show a clear shape: OpenCode crossed ~150K–172K GitHub stars and ~6.5M monthly active developers to become the default open-source choice, Codex CLI on GPT-5.5 took the benchmark performance lead, and Aider is visibly slowing, last repo push May 22 against d...
xAI launched Grok Build on May 14. With that, every major AI lab now ships a coding agent that lives in your terminal. The competition isn't "can we build one" anymore. That question is settled. The lineup: Anthropic has Claude Code. OpenAI has Codex CLI. Google has Gemini CLI...
sickn33/agentic-awesome-skills (~42,800 stars) packages more than 1,900 skills for Claude Code, Cursor, Codex CLI, Gemini CLI, Antigravity, and others, with curated bundles. That scale arrived days after Cisco open-sourced skill-scanner and shipped it into an IDE extension. No...
Announced at Google I/O on May 19 and detailed here, the harness added parallel-task subagents, cross-platform terminal sandboxing, credential masking, and hardened Git policies. In early June, Google reset Gemini quota counters to zero for everyone and shipped a refreshed Gem...
