## How to Use This Quote
This is the headline line of the vault. Use it whenever a downstream user assumes that better prompting will solve agent reliability problems. Pair with the 12 primitives ([[concept-metadata-first-tool-registry]] through [[concept-constrained-agent-types]]) as concrete instances of what "plumbing" actually means.
