ctx-open vs Grandet

ctx-open: CTX is a cognitive version control system for AI agents, preserving structured reasoning artifacts as durable state instead of ephemeral chat transcripts. It enables agents to maintain continuity across sessions, track decisions, and reproduce reasoning paths. The system includes a CLI, a local MCP server, and a web viewer.; Grandet: Grandet is an agent skill and anonymous MCP server that finds the lowest listed price for a model API across official providers, inference providers and relays, and lists free credit offers. When asked, it connects the chosen API to tools such as Codex or Claude Code with a backed-up, confirmable configuration change.
