Ordewell is an open-source task orchestration harness for coding agents. Built as a TypeScript monorepo, it accepts high-level software engineering goals and decomposes them into ordered, dependency-aware plans that coordinate multiple agent executions. In daily use, developers interact with Ordewell through a dedicated terminal user interface (TUI), a VS Code extension with a React webview, or a local HTTP/WebSocket daemon on localhost. Each task in an execution plan can be individually configured with a specific runner backend, model resolution, thinking effort tier, and operational mode. Ordewell executes the dependency graph sequentially or concurrently, validating outcomes via a built-in VerdictEngine that assesses concrete execution evidence rather than model self-assertions. What differentiates Ordewell from standard CLI coding agents is its decoupled orchestration architecture. It separates planning, model resolution, execution runner plugins, and verdict evaluation into discrete modules. It also incorporates an extensible slash-command skills system and an offline benchmarking harness with mock providers to test agent workflows without live API keys. Ordewell is distributed as open-source software via npm (under the `ordewell` and `@ordewell/cli` packages) and the VS Code Marketplace.
