About each tool
Claude 4.6 Sonnet
Claude 4.6 Sonnet represents the absolute best compromise of speed, cost, and high-level reasoning for most production software workloads. It delivers intelligence that rivals previous-generation Opus models while running at a fraction of the cost and at much faster execution times.Extremely popular among developers, a…
ITHZ MCP
ITHZ MCP helps AI-assisted development projects keep durable project memory next to the repo. It gives agents context packs, decisions, gates, risks, scoped claims, reviewer notes and explicit end-of-task checkpoints in project-owned files. Git remains the code history and transport; ITHZ MCP is not a Git replacement,…
