System Prompts Leaks timeline

System Prompts Leaks, maintained under the GitHub account asgeirtj, collects documents it describes as verbatim prompts from AI products. The repository was created on May 3, 2025. It includes material attributed to multiple vendors; inclusion is a community provenance claim rather than vendor authentication.

On November 3, 2026, the repository added a document labeled as Claude Code’s auto-mode safety classifier prompt. Readers can inspect the pinned file and its introducing commit without installing a plugin or supplying credentials. This is a document collection, not a coding-agent harness, model provider or verified reproduction of every product’s current behavior.
