Sorry, something went wrong.
std::println(stderr, ...) fails under `import std` (stderr/stdout/fflush are <cstdio> macros/functions not reachable without the header) — caught when building a project generated from llmapi@0.2.7:openai. Use std::cerr/std::cout stream overloads instead, and flush the chat prompts explicitly. tools/template_smoke.sh renders every template the way `mcpp new` does and builds it against this checkout (path dependency), so template code is compile-gated in CI before any release ships it. Version → 0.2.8 (0.2.7's default template is broken and will not be indexed).
mktemp dirs live outside the repo, where the `mcpp` shim has no workspace .xlings.json to resolve — CI failed with "'mcpp' is not installed". Render/build under target/template-smoke instead.

Building a project generated from llmapi@0.2.7:openai fails:
stderr/stdout/fflush come from <cstdio> and are not reachable under pure import std. All four templates now use std::cerr / std::cout stream overloads (and the chat template flushes its prompts).
Regression gate: tools/template_smoke.sh renders each template exactly like mcpp new ({{project.name}}/{{self.name}}/{{self.version}}), swaps the version dep for a path dep on the checkout, and mcpp builds it — wired into CI after the library build. All 4 templates compile locally (gcc 16.1.0, mcpp 0.0.53).
Version → 0.2.8; 0.2.7 will not be indexed (broken default template). mcpp-index PR will point at 0.2.8.
