MySpec

MySpec is an AI senior architect generates a four-file spec bundle for AI coding agents to prevent code hallucinations.

MySpec is an AI senior architect tool designed to prevent code hallucinations in Cursor, Claude Code, and Windsurf. The platform interviews developers to uncover edge cases and drafts a deterministic four-file spec bundle containing a constitution, requirements, solution, and tasks. It guides users through four stages consisting of describe, interview, specify, and export. The workflow produces immutable rules that remain constant across agent prompts to avoid context degradation. Supported formats include markdown, mermaid editor, and zip exports, alongside an HTTP MCP server and personal API tokens for unattended MCP.
