cli vs crystalline

cli: Archcore CLI provides a Git-native context layer for AI coding agents, storing project knowledge like architecture decisions and rules within a `.archcore/` directory, versioned with your code. This ensures agents load relevant, structured context at session start, improving their ability to follow conventions and decisions, and enabling new decisions to be recorded as durable context.; crystalline: Crystalline provides AI agents with crystallized intelligence, allowing them to accumulate and retain knowledge across sessions, unlike an LLM's fluid intelligence. It acts as a local search index on plain markdown files, enabling agents to onboard curated knowledge and capture new learnings, evolving from a stranger to a peer.

Use Cases

cli logocli
↳Ensuring AI agents follow established architecture decisions and coding conventions.
↳Recording new technical decisions or rules as durable, versioned context for future sessions.
↳Documenting incidents and their prevention steps, making them accessible to agents during relevant tasks.
↳Providing specific contextual information (e.g., relevant ADRs, rules) to agents before they modify a module.
crystalline logocrystalline
↳Onboard AI agents with curated domain-specific knowledge at the start of each session.
↳Enable AI agents to capture and persist new observations, decisions, and lessons learned from their work.
↳Facilitate team knowledge sharing and collaboration on a continually growing and evolving knowledge base.
↳Reduce redundancy and repeated explanations by providing agents with access to accumulated 'crystallized intelligence'.
↳Efficiently retrieve specific facts or context from a large collection of knowledge units based on task routing.
