Agent architectures have a six-month half-life as prompts and models keep changing

The thread argues that an agent architecture has a half-life of about six months because prompts change weekly and models change monthly.
The key complaint is that many teams couple too many layers together, so every new best practice or pattern forces a rewrite. The suggested takeaway is to design for change rather than for a single model or prompt stack.
This makes the post relevant to agent architecture, workflow abstraction, and long-lived engineering patterns in fast-moving AI systems.
