Agents driving agents

The fyolo sessions CLI turns the fleet into an API: any agent — or your own scripts — can start siblings, answer their prompts, and supervise the whole project without touching a GUI.

fyolo

main

fyolo://session/9b3e11d0  [done]  7 steps -> PLAN.md
fyolo://session/7c1f2a4e  [done]  +412 -128, tests pass
fyolo://session/5a77c0e2  [done]  2 nits, 0 blockers
fyolo://session/d4e6b209  [done]  clean, tagged v0.22.0

Your agents get the same commands you do: spawn a session, answer its prompt, read its reply.

What's inside

Built for agentic coding

Several agents going at once, most of them fine without you, one of them stuck — Fyolo keeps the whole fleet in view.

A fleet you can read

Every session reports a live status — working, finished, or blocked on you — and the same three states aggregate into the menu-bar tray.

Command palette

⇧⌘P runs any action, and Open Quickly jumps to any session, project, or file. Themes preview live as you browse them — Enter keeps, Esc puts it back.

Files beside the terminal

Browse the project, open files in a syntax-highlighted editor, read the git diff, search contents — a side panel that never pulls you out of the terminal.

Markdown you can actually read

Open a README or a plan and Fyolo renders it — GFM tables, task lists, math, Mermaid diagrams — in your terminal theme, beside the agent writing it.

Your other machines

Fyolo runs sessions on the hosts in your own ~/.ssh/config, each wearing its machine's mark. System OpenSSH does the connecting — no embedded client, no relay.

A worktree per agent

Worktrees are read straight from git and nested under the project, so two agents can work the same repo without ever touching each other's files.

Also in the box: your Claude and Codex plan limits read from your own credentials, hundreds of terminal themes with light, dark, and glass window looks, and Ghostty-style split panes.
