Why structured specifications matter more than code for AI agent reliability
Original: Your AI Agent Doesn't Have a Code Problem. It Has a Specs Problem.
Short summary
The article argues that AI agent failures stem from poor specifications, not code. It traces the evolution from ad-hoc specs to markdown PRDs to modular spec files, identifying problems like spec drift, contradictions, and lack of ownership. It then pitches CrystalSpec, a tool that treats specs as declarative contracts connected to existing project workflows.
- •AI agents need well-structured specs because they read tokens, not vibes
- •Markdown-in-repo specs eventually drift, contradict, and become unowned
- •CrystalSpec is pitched as a declarative spec tool designed for the agentic era
Generated with AI, which can make mistakes.
