Test-Driven Repair Loops blueprints
Engineering Loop: LangGraph Reflexion Deterministic State Machine (Actor-Evaluator-Reviser)
Deterministic implementation of the Reflexion architecture in LangGraph: Actor produces output -> Evaluator scores against ground truth/rubric -> Reviser reflects on critique -> Conditional loop back until quality threshold is met.
Engineering Loop: AlphaCodium Synthetic Edge-Test Generation & Self-Validation Stage
Stage dedicated to generating high-coverage synthetic unit tests covering edge conditions, corner cases, empty inputs, and maximum bounds.
Engineering Loop: Loop-Engine Goal-Directed Deterministic Controller
Pure-Python goal-directed loop controller demonstrating failure isolation, retry budgets, monotonic state progress, and stop conditions without LLM hallucination drift.
Engineering Loop: Loop-Engine Directed Acyclic Graph (DAG) State Transition Engine
Graph-based state machine defining nodes, typed transitions, validation predicates, and fallback edges for autonomous agent workflows.
Engineering Loop: Zeroshot Rust Autonomous Goal Supervisor & Run Ledger
High-performance Rust autonomous supervisor implementing atomic checkpoint commits, delivery gates, and hard resource limit enforcements.
Engineering Loop: SWE-Agent Competitive Programming & Edge-Case Loop
State machine optimized for competitive programming benchmarks with strict timeout bounds, edge test generation, and stdout matching.
Engineering Loop: AlphaCodium Multi-Stage Test-Driven Code Generation Flow
Full AlphaCodium multi-stage architecture: Problem Reflection -> AI Test Generation -> Public Test Run -> Iterative Code Fix on Failing Tests -> Multi-Candidate Selection.
Engineering Loop: Zeroshot Diagnostic Post-Mortem & Failure Isolation Engine
Rust failure isolation engine that analyzes crashed agent sessions, parses crash dumps and tail logs, and classifies failures into fatal vs recoverable.
Engineering Loop: OpenHands Cyclic Repetition & Loop Stagnation Breaker
Deterministic pattern analyzer that inspects the rolling history of actions and observations to detect infinite loops, repeating commands, and non-advancing edit cycles.
Engineering Loop: OpenHands AgentController Action-Observation Lifecycle Machine
Central coordinator state machine of OpenHands driving turn-by-turn agent execution, state persistence, delegate subagent coordination, and error containment.
Engineering Loop: Mini SWE-Agent Deterministic Exponential Backoff & API Retry Engine
Pure-Python deterministic retry controller implementing exponential jitter backoff, rate-limit isolation, and fatal error fast-fail.
