Athena Flow is a workflow runtime that wraps Claude Code via its hooks system. It receives the event stream, applies workflow and plugin logic, and renders everything in an interactive terminal UI with a live event feed.

Instead of writing throwaway prompts or one-off scripts to automate complex multi-step tasks, you define a workflow once — with prompt templates, loops, plugin bundles, and structured lifecycle hooks — and run it against any project.

The first workflow I shipped is e2e-test-builder. It navigates your app like a human, writes structured test case specs with preconditions, steps, and expected outcomes, then generates Playwright code from them.

The browser layer is handled by a separate MCP server I built called agent-web-interface, which produces semantic page snapshots instead of raw DOM — ~19% fewer tokens and ~33% faster task completion in early benchmarks against Playwright MCP.

The stack is three repos: athena-flow is the runtime (hooks -> UDS -> event pipeline -> TUI), agent-web-interface is the MCP server for token-efficient browser interaction, and athena-workflow-marketplace is where workflows and plugins live, resolved by ref like e2e-test-builder@lespaceman/athena-workflow-marketplace.

Workflows are composable — a workflow bundles plugins and can be shared via any Git repo. Writing your own is just a workflow.json and a prompt file.

Currently Claude Code only, but Codex support is in progress. Free if you already have a Claude Code subscription, no separate API key needed. MIT licensed.

Would love feedback, especially from anyone building on Claude Code hooks or thinking about workflow portability across agent runtimes.","url":"item?id=47254449","comments":[],"comments_count":0}
