See which coding agent is actually waiting for you
A zero-dependency terminal monitor that reads local session transcripts from Claude Code, Codex, Gemini and Antigravity, and shows from the outside which one is working — and which has been waiting on you.
The maker describes the design and review split
Single Python file from the repository; MIT
What it does
Stop checking five terminal windows: Sereno watches the sessions themselves and shows working, waiting, blocked or stopped at a glance.
Who it helps
Developers running several coding agents at once.
How it was made
- Models
- Claude Code · creator-reported
- Tools
- Claude Code · ImplementationPython · Single-file runtime, zero dependencies
- Sereno reads the local transcript files each agent already writes — nothing is sent anywhere.
- It distinguishes writing, inside-a-command, waiting-for-input and stopped states per session.
- The maker’s rule is blunt: “I designed and reviewed, Claude wrote” — one Python file, MIT, no dependencies.
What the person did
Alex Micó Robles designed the state model and reviewed the implementation; the public credit gives the writing to Claude.
What we know
Creator-reported: A usable public repository, a maker-authored post describing the build split, and a creator profile that links the project.
Access checked — 2026-09-27 · Opened the repository, the maker post and the creator profile on 2026-09-27; the scout dossier verified the same links the previous day.
Can you use it?
The repository is MIT and stays on GitHub; we link rather than host captures. The cover is an original Made With Models illustration, not a screenshot of the tool.
