What is capsule-identity?

A Rust library for managing isolated, verifiable identities and directives for AI agents within the Astrid OS ecosystem.

What does capsule-identity do?

Capsule Identity is a specialized Rust library designed for the Astrid OS platform to securely manage the identity and core directives of autonomous AI agents. It ensures that every agent possesses a distinct persona, operational class, and set of instructions, defined strictly through the `spark.toml` configuration format. The system builds and assembles the critical baseline system prompt before an agent initiates any task, guaranteeing behavioral consistency. By leveraging capsule KV isolation, it ensures that an agent's identity data remains completely scoped and secure from unauthorized access. The library also provides an interactive onboarding flow for newly instantiated agents, guiding them to establish their core identity seamlessly.

Who is capsule-identity for?

• Directive compilation: Automatically assembles and injects the baseline system prompt for an agent before task execution.
• Identity configuration: Defines an agent's specific persona, behavioral directives, and operational class using a standardized TOML file.
• State isolation: Secures agent identity data using capsule key-value isolation to prevent leakage or cross-contamination.
• Automated onboarding: Provides explicit onboarding instructions to guide new LLMs in generating and saving their identities.
• Pub-Sub communication: Integrates tightly with Astrid OS using a well-defined Inter-Process Communication protocol for status updates.
