Local-first crystalline intelligence for AI agents: the knowledge that endures across sessions, taught as Markdown Domains and captured as Engrams. One Rust binary with MCP server, CLI and hybrid search.
This repository also configures its own agents. See what crystalline tells them →
Skill Claude CodeCodex
Use when durable knowledge is learned while working, when the user asks to update a Crystalline domain, or before writing or editing an engram so it is deduplicated, well-formed and linked correctly.
Skill Claude CodeCodex
Use when working in a domain that has a team origin on GitHub - checking status at session start, updating before deep work, sharing new knowledge as a proposal, settling a conflict, or connecting a new teammate.
Skill Claude CodeCodex
Use when the crystalline MCP tools are available and the task involves recalling, storing or sharing knowledge - searching domains, capturing engrams or sharing with a team.
Skill Claude CodeCodex
Use when deciding which Crystalline domain(s) to search or read for a task, especially at session start, before reading a MANIFEST directly, when answering a broad question across domains, or when a "what is true now" question needs temporal filtering.
Skill Claude CodeCodex
Use when a Crystalline domain wants structure for one of its engram types - authoring a Picoschema schema engram, running inferschema to bootstrap one from what is already captured, or validateengrams to check conformance.
