# Prompt Labs - Leaked System Prompts ## LLMs ### [Aider](https://www.aider.ai): AI-powered coding assistant that helps developers modify codebases efficiently through natural language prompts and context-aware code changes #### Latest - [Architect Mode](leaks/aider/2025-07-07_prompt_architect-mode.md): outlining how an AI acts as an expert architect engineer to provide clear, concise, and change-focused instructions to an "editor engineer" for modifying code within a git repository - [Ask Mode](leaks/aider/2025-07-06_prompt_ask-mode.md): as an expert code analyst AI, detailing its read-only nature for code analysis and question answering, its emphasis on brief responses, and its capability to request additional files for analysis. - [File Mode](leaks/aider/2025-07-06_prompt_file-mode.md): "file listing" format for an AI assistant, which involves returning the entire content of a file (either existing or new) within a specific fenced code block structure to propose code changes. - [Patch Mode](leaks/aider/2025-07-06_prompt_patch-mode.md): "V4A Diff Format Rules" used by an expert software developer agent, detailing how it should propose code changes, create new files, and refactor existing ones using a unified patch format with context-aware diffs for Add, Update, and Delete operations. - [System Prompt](leaks/aider/2025-07-06_prompt_system.md): AI software developer coding best practices, interaction rules, and the precise `SEARCH/REPLACE` block format for code modifications. - [Udiff Mode](leaks/aider/2025-07-06_prompt_udiff-mode.md): "udiff-mode" system prompt for an AI assistant, which instructs the assistant to output code changes in a unified diff format similar to `diff -U0`. ### [Alan](https://alan.estsoft.ai/): AI assistant developed by ESTsoft that provides advanced conversational and productivity features for users and businesses #### Latest - [Prompt](leaks/alan/2023-09-20_prompt.md): outlines the detailed rules and limitations for "Alan Assistant
Agent that generates comprehensive documentation, API references, architecture diagrams, and developer onboarding guides from existing code.
Agent configuration for systematic bug investigation that traces issues from error logs through the codebase to root cause with suggested fixes.
Agent for integrating third-party APIs including SDK setup, type generation, error handling, retry logic, and rate limit management.
Cursor's built-in autonomous coding agent that can make multi-file edits, run terminal commands, search the codebase, and iteratively build features with minimal human intervention.
Cloud-based autonomous coding agent that runs in the background on remote sandboxed environments, handling complex multi-step tasks while you continue working.
Cursor's multi-file editing agent within Composer mode that can create, edit, and delete files across your entire project in a single conversation.
