Feature & Specification Comparison

Specification	Glm MCP djerok Coding Agents	Preflight preflight-dev Coding Agents
Summary	Run GLM (Zhipu/Z.ai) as a real sub-agent inside Claude Code or GitHub Copilot. GLM gets its own agent loop (read/write/edit/run) on your repo — not a single LLM call — with peak-aware Opus-vs-GLM routing, diff/dry-run/git-revert oversight, and a usage ledger. 10x cheaper than Opus. Requires a Z.ai GLM Coding Plan key.	24-tool MCP server for Claude Code that catches vague prompts before they waste tokens. Includes 12-category prompt scorecards, session history search with LanceDB vectors, cross-service contract awareness, correction pattern learning, and cost estimation.
