The 7-Module Agent Engineering Roadmap
Study these modules in sequential order to build a rock-solid mental model of modern agentic systems:
Claude Code & Terminal Coding Agents
Core Concept: Operating autonomous CLI agents that navigate codebases, inspect diffs, execute terminal commands, and solve complex multi-file engineering problems directly in your shell.
- The CLI agent loop: perception → tool selection → execution → reflection.
- Terminal safety rails, permission boundaries, and background process management.
- Configuring
CLAUDE.mdarchitecture guides and memory files for long-horizon tasks.
Complete walkthrough of terminal agent loops and workflow architecture.
Agent Skills & Extensibility Architecture
Core Concept: How to build modular, declarative capability packages that teach agents how to perform specialized workflows without bloating the system prompt.
- The
SKILL.mdspecification: YAML frontmatter, execution instructions, and validation gates. - Progressive context loading: keeping context windows lean by dynamically loading scripts only when triggered.
- Packaging deterministic bash and python tools alongside semantic agent instructions.
Creating reusable skills and extending agent capabilities modularly.
Agent Evaluation & Eval-Driven Development (EDD)
Core Concept: You cannot improve what you do not measure. How to build rigorous eval suites that gate prompt updates and code releases with quantitative pass rates.
- The difference between deterministic unit tests and semantic LLM-as-a-judge rubrics.
- Pass@1, Pass@k, and regression benchmark tracking.
- Building synthetic golden evaluation datasets from historical production edge cases.
Setting up automated grading pipelines and eval harnesses.
LLM Foundations & Transformer Mechanics
Core Concept: Understanding the underlying mathematics and architecture of auto-regressive transformers to predict failure modes and optimize context usage.
- Self-attention mechanisms, query-key-value vectors, and positional embeddings.
- Tokenization pitfalls, needle-in-a-haystack context degradation, and KV caching.
- Sampling temperature, top-p, and logit bias mechanics.
Deconstructing attention, transformer blocks, and token dynamics.
LLMOps, Tracing & Production Guardrails
Core Concept: Taking agents from local prototypes to robust production environments with end-to-end tracing, rate-limiting, and runtime error recovery.
- Full execution tracing with LangSmith and Langfuse: inspecting latency, tokens, and prompt payloads.
- Defensive guardrails: input sanitization, JSON schema enforcement with Pydantic, and hallucination tripwires.
- Cost allocation, model tiering (fast flash models vs frontier reasoning models), and cache hits.
Tracing, observability, cost monitoring, and guardrails at scale.
LangGraph & Multi-Agent State Machines
Core Concept: Orchestrating multiple specialized agents working together in cyclic state graphs with deterministic branching, persistence, and human oversight.
- State definitions, node execution, and conditional edge transitions.
- Hierarchical patterns: Supervisor → Worker → Evaluator multi-agent clusters.
- Time-travel debugging and human-in-the-loop approval gates before high-stakes actions.
Designing complex cyclical state machines and multi-agent teams.
Machine Learning & Fine-Tuning Fundamentals
Core Concept: When prompting and RAG hit their ceilings, learn how to adapt open-weight models (Llama, Mistral, Qwen) using Parameter-Efficient Fine-Tuning (PEFT).
- High-quality dataset curation: synthetically bootstrapping training pairs with frontier reasoning models.
- LoRA (Low-Rank Adaptation) and QLoRA: training 70B parameter models on single consumer GPUs.
- Direct Preference Optimization (DPO) and RLHF alignment strategies.
Hands-on training, loss curves, dataset curation, and LoRA adapters.
