If you only look at twelve things, make it these:

| If you want to… | Start with | Why | |---|---|---| | Understand agents from first principles | [An Introduction to MultiAgent Systems](#classic-books-pre-2024) | The canonical MAS textbook | | Connect MAS to game theory | [Shoham & Leyton-Brown](#classic-books-pre-2024) | Free online; the algorithmic/game-theoretic foundations | | Learn MARL properly | [MARL: Foundations and Modern Approaches](#recent-books-2024) | Free modern textbook with code and slides | | Run reproducible MARL experiments | [PettingZoo](#marl-simulation-and-classic-mas-platforms) + [BenchMARL](#marl-simulation-and-classic-mas-platforms) | Standard environment API + standardised benchmarking pipeline | | Beat a hard cooperative benchmark | [SMACv2](#datasets-and-benchmarks) | The de-facto cooperative MARL challenge, randomised to resist overfitting | | Evaluate social generalisation | [Melting Pot](#datasets-and-benchmarks) | Tests generalisation to new co-players, not just new tasks | | Map the LLM multi-agent space | [Guo et al. survey](#recent-high-impact-papers-and-surveys) | The most practical overview of methods and open problems | | Build an LLM agent team | [Framework comparison](#which-framework-should-i-use) | Pick by use case, not by star count | | Learn from a production system | [Anthropic's multi-agent research system](#how-to-guides-and-framework-docs) | Candid engineering retrospective: when multi-agent beats single-agent | | Know why agent teams fail | [Why Do Multi-Agent LLM Systems Fail?](#recent-high-impact-papers-and-surveys) | Empirical failure taxonomy — read before shipping | | Connect agents to tools and data | [Model Context Protocol (MCP)](#agent-interoperability-protocols) | The industry-standard tool/context interface | | Make agents talk across frameworks | [Agent2Agent Protocol (A2A)](#agent-interoperability-protocols) | Cross-framework agent-to-agent communication |

Getting started: three pathways

Different readers need different entry points. Pick the pathway that matches you:

🎓 New to MAS research — start with Wooldridge's [An Introduction to MultiAgent Systems](#classic-books-pre-2024), then the [seminal papers](#seminal-papers-and-milestone-work) (Contract Net → BDI → Dec-POMDP complexity), and browse the [taxonomy](#field-guide-taxonomy-and-milestone-timeline) to find your subfield.

🤖 MARL practitioner — the [MARL book](#recent-books-2024) (free online) for foundations; [PettingZoo + BenchMARL](#marl-simulation-and-classic-mas-platforms) to run reproducible experiments; [SMACv2 and Melting Pot](#datasets-and-benchmarks) as benchmarks; MAPPO as the baseline to beat.

🧠 LLM-agent builder — start with the [Guo et al. survey](#recent-high-impact-papers-and-surveys) for the map, pick an orchestration framework from the [comparison table](#which-framework-should-i-use), wire up tools/communication via the [MCP and A2A protocols](#agent-interoperability-protocols), and read [Why Do Multi-Agent LLM Systems Fail?](#recent-high-impact-papers-and-surveys) before shipping.

Curated resources

Two-tier curation: milestones (foundational, field-shaping work) and recent (2021–2026, emphasising benchmarks, reproducibility, and LLM-based multi-agent systems). Entries follow the format Title — (Year) Authors · annotation · tags; anything not verifiable from a primary source is marked unspecified. Star counts are live badges via shields.io.
