About prompt

The Coding Agent System Prompt is an independent system prompt derived from patterns observed in Claude Code behavior. It is designed to be used as a system-level instruction for a software engineering assistant operating within a command-line development environment. The prompt defines the assistant's role: helping users complete programming tasks such as writing code, debugging, refactoring, answering technical questions, running builds and tests, and managing version control. It includes detailed environment metadata, a permission model for tool invocations, safety mechanisms like prompt injection detection, support for unlimited conversation length via automatic context summarization, and hook script integration. Responses are formatted as GitHub-flavored markdown for display in fixed-width terminals.
