What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-29, confidence not recorded

A Rust-based system prompt builder that assembles an AI agent's identity from workspace config (spark.toml) and persisted capsule KV state. It acts as the identity module ('/etc/profile') of Astrid OS, handling onboarding and publishing assembled prompts over an IPC event protocol.

Use cases

  • build system prompts for AI agents from config files
  • persist and recover agent identity across sessions
  • onboard users by collecting agent identity via LLM tool calls
  • assemble identity and environment context into LLM prompts
  • manage agent identity state with KV isolation

When to choose

  • you are building agents on Astrid OS or its capsule/IPC model
  • you need structured, persistent agent identity with onboarding flows
  • you want a Rust component that assembles system prompts from config and state

When to avoid

  • you need a general-purpose prompt library outside the Astrid OS ecosystem
  • you want a standalone agent runtime rather than an identity/prompt module
  • you need a framework-agnostic prompt builder with no IPC event dependencies
