Specweave

Specweave is an AI development tool that plans work as specs, builds tasks autonomously, and syncs across coding agents.

SpecWeave is a spec-first AI development framework that helps users plan work as small specs, hand tasks between tools like Claude, Codex, and Grok, and close tasks with test evidence. It works by creating a structured folder for each increment with a spec file and an append-only ledger that tracks claims and evidence. It is designed for developers using AI coding assistants who want to switch tools, handle token limits smoothly, and maintain project memory across sessions. What sets it apart is its ability to synchronize work between different AI vendors, maintain shared project memory in the code repository, and coordinate multi-agent teams. It supports GitHub, Jira, and Azure DevOps for external synchronization.
