# The AI agent stack

Autonomous agents plan, call tools, and act over multiple steps. The stack pairs an agent runtime with model tooling, integration glue, and tracing.

## 1. AI Agents

Agent runtime - planning, tool use, and multi-step control flow.

**When not to use:** Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism.

- [ECC](/tools/affaan-m-ecc.md) - The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Code (★ 226,953)
- [hermes-agent](/tools/nousresearch-hermes-agent.md) - The agent that grows with you (★ 210,874)
- [AutoGPT](/tools/significant-gravitas-autogpt.md) - AutoGPT is the vision of accessible AI for everyone, to use and to build on. Our mission is to provide the tools, so that you can focus on w (★ 185,418)
- [ollama](/tools/ollama-ollama.md) - Get up and running with Kimi-K2.6, GLM-5.1, MiniMax, DeepSeek, gpt-oss, Qwen, Gemma and other models. (★ 175,657)

## 2. LLM Frameworks

Framework & tooling - prompt/state management and RAG the agent can call.

**When not to use:** Skip the framework layer if your agent only needs one or two hardcoded tools.

## 3. Developer Tools

Gateways & SDKs - route across model providers and expose tools (e.g. via MCP).

**When not to use:** A gateway is overkill when you're pinned to a single provider and model.

## 4. Evaluation & Observability

Tracing - see every step, tool call, and token so failures are debuggable.

**When not to use:** There is no good reason to run agents in production without tracing.
