AI & LLM Resources

Awesome AI Coding Lists

Twelve community-maintained GitHub awesome lists for AI/LLM coding in 2026 — tools, prompt collections, MCP servers, frameworks, and learning resources, with named maintainers.

LLM Coding Techniques

Agentic Coding Levels (Shapiro Five Levels)

Dan Shapiro's five-level autonomy ladder for AI coding, from spicy autocomplete to the dark software factory — modeled on NHTSA's driving levels.

LLM Coding Techniques

Harness Engineering for AI Coding Agents

Build everything around the LLM — tools, MCP, hooks, evaluators, memory, sandboxes — so an agent ships code instead of just generating it.

LLM Coding Techniques

Agentic Coding Workflows

Design effective workflows for autonomous LLM coding agents. Planning, execution, and verification patterns.

AI Prompts & Templates

System Prompts for Agentic Coding

Effective system prompts for LLM coding agents. Structure, constraints, and output formatting for reliable code generation.

LLM Coding Techniques

Context Management for AI Coding

Manage LLM context windows for AI coding — token budgets, file pruning, summarization, and retrieval patterns that keep Claude, GPT-4, and Gemini focused on the task.
