vshulcz/deja-vu

Vshulcz has developed a tool called Deja Vu, which enables retroactive search and recall of session logs for coding agents. This tool can help improve the efficiency and accuracy of coding tasks. Vshulcz has made Deja Vu open-source and available on GitHub.

Why it matters

Deja Vu is important because it addresses a common problem in coding agent development, which is the inability to recall previous interactions. By providing a solution to this problem, Deja Vu can enhance the overall performance of coding agents.

Try thisDownload and install Deja Vu, then experiment with using it to improve the recall of your coding agents.
