Run parallel, token-efficient code generation pipelines with hosted Cerebras LLMs: explore 2-5 architectures simultaneously, spawn competing runners to implement designs from specs, score candidates on fitness/readability/robustness/maintainability via tests, and write winning multi-file code (e.g., Python/FastAPI) directly to disk—saving ~60% tokens.
npx claudepluginhub 2389-research/claude-pluginsExplore different architectural approaches in parallel using hosted LLM for code generation. No restrictions on approach - fastest path to comparing real implementations. Part of speed-run pipeline.
Scoring framework for speed-run showdown and any-percent. Invoked at Phase 4 to evaluate implementations using 5-criteria scoring. Do not invoke directly - called by showdown/any-percent.
Same design, multiple parallel runners compete using hosted LLM for code generation. Each runner creates own plan, generates code via Cerebras, pick the best. Part of speed-run pipeline.
Direct code generation via hosted LLM (Cerebras). Write a contract prompt, generate code, fix surgically. Part of speed-run pipeline.
