Evaluating AI Coding Tools: Blind A/B Tests on Real Tickets

Run blind A/B evaluations across Cursor, Claude Code, and Copilot on real production tickets measuring time-to-merge, revert rate, and review comment severity—not vanity accept rates.

Bedrock Agents Memory: Session Scratchpads Versus Long-Term Stores

Separate Bedrock agent session scratchpads from long-term memory stores, redact secrets and PII before persistence, and expire session state aggressively to prevent cross-user memory leakage.

AI Node.js

Node SDK Generation: OpenAPI-Driven Clients LLMs Cannot Hallucinate

Generate typed Node clients from OpenAPI with schema validation gates and compile-time checks so hallucinated endpoints and fields never make it into application code or pull requests.

AI Debugging

AI On-Call Copilots: Suggest Runbooks Without Mutating Production

Deploy read-only on-call copilots that propose kubectl and AWS CLI remediations with dry-run flags and change tickets, never executing writes until an on-call engineer explicitly approves.

Prompt Caching Pitfalls: Stale Coding Rules After Major Repo Moves

Detect when Bedrock prompt caches serve outdated coding standards after large refactors—invalidate by content hash rather than TTL alone so agents stop enforcing deleted patterns for days.

AI AWS System Design

Secure AI Sandboxes: Ephemeral ECS Tasks for Agent Tool Execution

Execute agent shell and test tools inside short-lived ECS tasks with no long-lived credentials, disk quotas, and egress allowlists so a compromised session cannot reach production data stores.

AI Machine Learning

Code RAG Rerankers: Cross-Encoders After Cheap Vector Recall

Add a cross-encoder rerank stage after OpenSearch kNN recall so the final top-k code snippets actually answer the developer question instead of merely sharing embedding neighborhood proximity.

AI-Written Terraform: Plan Diff Gates Before Any Apply Runs

Require terraform plan artifacts, OPA policy checks, and human approval whenever models propose infrastructure—never auto-apply IAM, network, or KMS changes from an unattended coding agent.

Lambda Authorizers: Bedrock Policy Explanations With Hard IAM Denies

Prototype LLM-assisted explanations inside Lambda authorizers while keeping hard allow and deny decisions in deterministic IAM and Cedar policies—never let the model be the final gate alone.

Cursor Notepads: Living Architecture Constraints Agents Must Obey

Maintain Cursor notepads for bounded contexts, event schemas, and forbidden libraries so agent edits respect architecture intent instead of inventing cross-domain coupling seniors must unwind later.
