Former GitHub CEO's new project Entire open-source skills: enabling 5 types of programming agents to share memory and seamless handoff

According to Beating Monitoring, the former GitHub CEO Thomas Dohmke founded Entire, an open-source set of skills plugins for cross-programming agents called Skills. Once installed, five agents—Codex, Claude Code, Gemini, OpenCode, and Cursor—can read the same development context and seamlessly hand off tasks between different agents.

The CLI tool previously open-sourced by Entire automatically records the agent’s prompts, reasoning processes, and modified files every time a git commit, generating a “checkpoint” (a paired snapshot of code changes and the agent dialogue that produced them), stored on a separate git branch without affecting normal commits. Skills are built on these checkpoints and currently offer three features: automatically generating structured summaries when handing off work between agents to save manual context restatement; tracing any line of code back to the original agent dialogue that created it; and searching all historical checkpoints by topic, branch, author, or time period.

Dohmke served as GitHub CEO from 2021 to 2025, leading Copilot’s transition from experimental feature to mainstream tool. In February this year, he founded Entire with a seed round of $60 million (led by Felicis, valuation at $300 million), making it the largest publicly disclosed seed round in the developer tools field. The team consists of 15 members from GitHub and Atlassian.
