elizaos

name: elizaos description: "Use when the task involves elizaOS core runtime concepts, plugins, actions, providers, evaluators, services, memories, state composition, or upstream elizaOS development. Covers the main abstractions and the TypeScript runtime mental model."

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/typescript/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.
