Every AI agent writes the same code from scratch every time. It generates a REST handler for the tenth time as if it has never seen one before. It writes the same error handling boilerplate, the same pagination logic, the same auth middleware -- from zero, every time, with no memory of what worked before.
The current fixes do not work. Template engines produce rigid output that breaks when requirements deviate. Snippet libraries store text, not patterns -- they cannot adapt to new variable names, types, or structures. Fine-tuning is expensive, slow, and locked to one model.
Current AI: Cold start on every build. No reuse. No learning. No acceleration. AgenticEvolve: Crystallizes verified patterns from successful builds and matches them to new contexts, so the first build takes a minute and the hundredth takes fifteen seconds.
cargo install agentic-evolve-cli
evolve --help- Problem: AI agents regenerate identical patterns from scratch on every project. Solved: pattern crystallization extracts reusable patterns from verified code, indexed by signature, domain, and context -- the agent remembers what worked.
- Problem: there is no confidence signal for generated code quality. Solved: every pattern tracks success rate, usage frequency, and decay score -- the agent knows which patterns are battle-tested and which are speculative.
- Problem: code reuse requires exact matches, which rarely happen across projects. Solved: four matching strategies (signature, context, semantic, fuzzy) find applicable patterns even when variable names, types, and structures differ.
- Problem: combining multiple patterns into coherent code is manual and error-prone. Solved: pattern composition with gap filling and adapter generation assembles multiple patterns into working code with consistent types and interfaces.
- Problem: pattern libraries grow stale as languages and frameworks evolve. Solved: decay management and promotion engines automatically deprecate unused patterns and elevate frequently successful ones.
# Crystallize what works, reuse what is proven -- three commands
evolve crystallize --file src/handlers/user.rs --function create_user
evolve match signature "pub async fn create_user(input: CreateUserInput) -> Result<User>"
evolve compose --patterns p1,p2,p3 --output src/handlers/task.rs
