## Multi-Agent Arena

Multi-Agent Arena sits inside Olam Labs' broader effort to scale simulated worlds for frontier AI labs. The premise is that richer simulations drive more capable and safer models, so the team builds environments where several models interact at once and their behaviour can be measured rather than merely observed in a single chat. Games provide the shared rules and incentives that make social behaviour comparable across models.

The suite covers titles with genuinely different payoff structures: Diplomacy, where alliances and betrayals shape outcomes; Poker, which tests bluffing and reading opponents; Risk, which mixes long-horizon planning with temporary cooperation; and other negotiation scenarios. Because each game creates its own pressures, the same model can look cooperative in one and self-interested in another, and the resulting data is what the evaluations are built on. Public releases have reported metrics such as broken promise rates and relative share of spoils across model families.

Access is free, and the site publishes essays, release notes, and evaluation write-ups alongside the arena itself. Olam Labs frames the work around research throughput, arguing that infrastructure and grading capacity are the real bottlenecks in studying multi-agent behaviour, and it collaborates with labs and researchers on reinforcement learning, evaluation, and post-training use cases.

**Pricing & Plans:** Free. There is no paid tier advertised; the arena and published research material are openly available.

- **Multiple games with distinct incentives:** Diplomacy, Poker, Risk, and other negotiation scenarios each create different pressures, so a model's social behaviour can be compared across contexts.
- **Multi-agent evaluation data:** Matches generate measurable outcomes such as broken promise rates and share of spoils, turning vague impressions of model personality into comparable numbers.
- **Designed for model comparison:** Several models can be placed in the same scenario, making head-to-head differences in cooperation, deception, and negotiation visible.
- **Published research and release notes:** The team documents findings, updates, and collaborations so results can be read alongside the arena itself.
- **Free to use:** The arena is open at no cost, aimed at researchers, builders, and anyone curious about multi-agent dynamics.

**Strengths:** Free access with no account barrier described; Games give structured, comparable incentives that plain chat evaluation cannot provide; Covers both cooperative and adversarial dynamics in one environment; Backed by published research and release notes from the Olam Labs team

**Limitations:** It is a research and evaluation environment rather than a polished consumer game; Interpretation of results requires some familiarity with agent evaluation; Behaviour in a specific game does not directly predict real-world deployment behaviour

## Skillry

Skillry is a curated library of Agent Skills — reusable packages of instructions, templates and scripts that AI coding agents can install and run. The concept is straightforward: give an agent a well-designed workflow, and it can produce a complete, presentable artifact rather than a rough draft. Skillry focuses on deliverables you would actually show, spanning web pages and landing pages, slide decks, images such as OG graphics, and short videos.

The key differentiator is that Skillry designs the output first. Its team art-directs a finished piece — a page, a deck, a film — then writes the original instructions, templates and scripts that let your agent reproduce that style. Each Skill page displays a real result it made, so you can see the visual point of view before installing. Skills are maintained by the same team as agents and models evolve.

Installation is agent-first. You can browse the catalog on the web, connect via MCP so your agent can search and inspect Skills, or install from the CLI. Free Skills require only a sign-in, while Premium Skills come with a Pro subscription or a one-time lifetime purchase. Model, API and rendering costs are handled by your own environment, not by Skillry.

**Pricing & Plans:** Free Skills are available with a sign-in. Pro is $9.99/month (regularly $19.90) or $79/year (regularly $158), and a Founding Lifetime plan costs $169 one-time. All paid plans include Premium Skills, MCP/CLI/web install and ongoing updates; model and rendering costs are extra.

- **Original in-house Skills:** Every Skill is designed, written and tested by the Skillry team, with templates and scripts built from a finished piece of work.
- **Multiple output types:** Skills cover web pages, slide decks, images, video and reports, so your agent can produce a range of assets.
- **Broad agent support:** Install and run Skills inside Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI and more.
- **Preview before install:** Each Skill page shows a real result it generated, so you can judge the visual style before adding it.
- **Flexible installation:** Add Skills from the web, through an MCP connection or from your CLI, with browser-based authorization.

**Strengths:** Original Skills designed and maintained in-house; Covers websites, slides, images and video in one library; Works across Claude Code, Codex, Cursor and many other agents; Each Skill previews a real result before you install

**Limitations:** Full access to Premium Skills requires a paid plan; Model, API and rendering costs are separate from the subscription; The catalog is newest to market, so coverage keeps evolving
