elizaOS

elizaOS is the plugin-based agent runtime that Eliza builds on top of.

Read These References First

• references/core-abstractions.md for the runtime mental model and message flow
• references/plugin-development.md for plugin extension points and implementation patterns

Use This Skill When

• a change touches eliza/
• you need to reason about AgentRuntime
• you are implementing or debugging actions, providers, evaluators, services, or model handlers
• you need the correct plugin lifecycle instead of guessing from Eliza wrappers

Working Rules

• Treat the TypeScript runtime in eliza/packages/core/src/ as the primary reference implementation.
• Prefer elizaOS-native abstractions over product-specific wrappers when reasoning about upstream behavior.
• Remember the split between persistent Memory and ephemeral State.
• Remember that plugins are the main composition mechanism.
