AI-DLC: adaptive workflow steering rules for coding agents

AWS Labs open-source (5k+★): one harness-neutral core turns Claude Code/Codex/Cursor/Copilot/Kiro/opencode into structured, verifiable delivery workflows via `aidlc config --harness` + doctor—install script, not a new agent.

Claustrum: harness-neutral architect that delegates to any coding agent via MCP

Claustrum (alpha, .NET NativeAOT) is a harness-neutral conductor: an architect in Claude Code, Cursor, Copilot CLI, opencode, or desktop delegates builds/reviews/tests to agents on any other harness/model and gets one normalized JSON receipt. Two doors — `claustrum run` CLI and `claustrum mcp` stdio server. Parallel builders on git worktrees, budget ledger, backends doctor. Role-based routing (strong model for architect/reviewer, cheap for builders) without locking the pipeline to one vendor.

Kerno: local runtime QA that verifies agent changes against your stack

MCP-connected runtime QA maps critical flows and entry points, then re-tests the blast radius of each Claude Code/Cursor/Codex change against live Postgres/Kafka/APIs/MCP tools—contracts, authz, OWASP, errors—before merge, with self-heal when behavior changes on purpose.

NVIDIA RTX Spark: decision models + local/cloud HydraFusion for coding agents

NVIDIA (Oct 16) details RTX Spark as a single-machine coding-agent workstation: decision models in llama.cpp/Unsloth choose next actions up to ~200x faster than long reasoning loops; HydraFusion prompt router escalates only when local models aren’t enough; GitHub Copilot gains Windows ML + llama.cpp local backend; Junie Local and Pi optimized. Pair with open Nemotron Bolt 74B-A9B 24GB for on-device agents via Ollama/vLLM/LM Studio.
