Decispher automatically captures engineering decisions from your pull requests and serves them to AI coding agents via MCP. When a PR is opened, Decispher analyzes the diff, links it to your team's existing decision history, and comments with relevant context, before anyone merges. Approved decisions generate CLAUDE.md, .cursorrules, and AGENTS.md committed directly to your repo, giving Claude Code, Cursor, and Copilot the full why behind your codebase.
