AI Agent GitHub Digest — 2026-10-06
**replica-skill** (469 stars) is eleven chained Claude skills that reverse-engineer an app, rebuild it, test it, read what its users actually hate and fix that, then deploy your clone live. **qiaomu-codex-imagegen** (91 stars) wraps Codex's built-in image generation — normally usable only inside Codex — into an MCP server, CLI, and skill any agent can call. **mesh-avatar-studio** (228 stars) has a coding agent read an illustration, auto-slice it into layers and rig it, then a local editor lets you fine-tune it into a 2D avatar that blinks, talks, and turns its head. **easyread** (803 stars) is a local paper reader that translates English PDFs into Chinese page by page, keeps equations typeset with KaTeX, and lets you flip back to the original text anytime. On the framework side, Mastra shipped @mastra/core@1.74.0 on 10/5, letting tools read the full conversation mid-execution and reshaping the Playground UI's trace pagination API (a breaking change).
