Archon Prompt Builder Architecture for AI Assistant Interactions

April 10, 2026 coleam00/Archon ↗

Archon’s prompt builder assembles deterministic system prompts by combining project metadata, workflow definitions, and routing rules through modular formatter functions located in packages/core/src/orchestrator/prompt-builder.ts.

The prompt builder for AI assistant interactions in the coleam00/Archon repository provides a structured approach to contextualizing LLM conversations. Located in the core orchestrator package, this TypeScript module transforms database records and workflow definitions into markdown system prompts that guide Claude or Codex models in routing user requests between direct answers and workflow invocations.
