## Definition

A GitHub AI agent is an autonomous system that reads issues, pull requests, and repository content, then takes actions — commenting, committing, merging — inside GitHub Actions without a human approving each step. It runs on models like Claude, GPT, or Gemini through GitHub's own orchestration layer, not just editor autocomplete.

GitHub's own engine for this, [GitHub Agentic Workflows](https://github.blog/changelog/2026-06-11-github-agentic-workflows-is-now-in-public-preview/), entered public preview on June 11, 2026: teams write agent instructions as Markdown, which GitHub compiles into hardened Actions YAML for issue triage, CI-failure analysis, and documentation upkeep across repositories, orchestrated by Claude, Copilot, Codex, or Gemini.

## Example

Noma Security's July 7, 2026 "GitLost" disclosure showed the risk concretely: a public GitHub Issue containing the word "Additionally" tricked an org's agentic workflow into fetching a private repository's README and posting it as a public comment, with no credentials required.

## Analogy

Think of it as an eager intern with a master key, reading every note left in the public mailbox and obeying the last one.

## Why it's emerging now

GitHub pushed Agentic Workflows into public preview on June 11, 2026, then a week into July, Noma Security's GitLost disclosure showed the same agents could be tricked by a public GitHub Issue into leaking private repository data — turning a developer-productivity feature into a live security story.
