+The “One-Tool Mousetrap” is a concise manifesto for adopting CUE (Configure-Unify-Execute) as the single source of truth for configuration and policy.  
+It attacks the common multi-stage YAML stack:
+
+1. YAML hand-edited by humans  
+2. Jinja2/Go-template rendering → JSON  
+3. Some external validator (Kubeval, OPA, custom scripts)  
+4. If validation fails, loop back and edit again (runtime surprise)
+
+The anti-pattern is that you only discover type/syntax/semantic errors after rendering, when the cost of repair is highest.
+
+CUE inverts the flow:
+
+- CUE schema + data (both expressed in CUE’s own language)  
+- `cue export` (a single binary)  
+- Immediately emits valid YAML/JSON/Dockerfile/INI, already linted against the schema.
+
+Thus the same surface (CUE) is:
+
+• The linter (static analysis)  
+• The schema (type & constraint def)  
+• The template (data transformation)
+
+Zero runtime surprises because validation and generation happen in one atomic step.
+
+In short: “CUE collapses the stack.”
