a workshop OS for agents
build the agent only_you_need
A local-first macOS workspace bringing your coding agents, tools, memory, and apps together — extensible through plugins as your work changes.
§ 01 the_pain
Most AI tools don't know your project.
They run in a separate tab, start fresh every session, and need you to explain yourself from scratch. You end up bridging the gap manually — copying context, switching windows, repeating yourself.
→ Sero puts the agent inside your workspace, where it can see your files, run tools, and remember what matters.
§ 02 self_extension_loop
Need something Sero doesn't do yet? You can add it.
// Ask. Build a plugin. Use it straight away.
01
Ask · chat → describe the capability
Tell Sero what you need: “I want a weekly planner for this project.”
02
Build · plugins/weekly-planner/{manifest, tool.ts, App.tsx}
Sero helps you scaffold a plugin — a manifest, some tools, and optionally a UI panel.
03
Activate · Admin → Plugins → Local · status: live
Load it in Admin → Local Plugin Development. It’s live inside Sero immediately.
04
Use · sidebar.app: weekly-planner · tool: planner.add_task
The new tool, panel, command, or widget appears in the workspace.
05
Keep improving · diff: planner@0.2 → planner@0.3
Next week, ask Sero to extend it. The capability stays.
§ 03 what_can_it_become
build the agent you actually want.
--assistant Personal assistant
Reminders, recurring prompts, profiles, personal memory.
- + Scheduler plugin
- + Memory plugin
- + Web plugin

> “Remind me each Friday to log expenses, then file them.”
--research Research desk
Search, sources, bookmarks, summaries, saved context.
- + Web plugin
- + MCP plugin
- + Custom skills + agents
example ask
> “Build a paper-tracker plugin that watches arXiv categories.”
--ops Operations console
Dashboards, monitors, routines, external APIs, jobs.
- + Plugin UIs + widgets
- + Background runtimes
- + Provider plugins
example ask
> “Make a deploy console that pings my staging cluster.”
§ 04 what_it_can_do
a few things worth knowing.
Three projects on port 3000. No conflicts.
Each workspace runs in its own container. Dev servers listen on isolated network addresses, so projects never step on each other’s ports. Containers start in seconds and switch instantly.
Built-in specialists. Or make your own.
Scout, reviewer, test-writer, and more ship by default. Each is a plain Markdown file you can edit, customise, or duplicate. You can also ask Sero to create a new specialist agent from scratch.
The agent can see your running app.
Sero has a built-in browser that opens dev servers and any URL. The agent can take screenshots, record short clips, and check its own work visually — without you having to describe what you see.
§ 05 starting_abilities
useful from the start. yours over time.

§ 06 honest_alpha
early, useful, built in public.
source-only OSS alpha · macOS · apple silicon · profile-scoped state · container-backed workspaces when available · host-mode fallback otherwise · plugin/runtime contracts will evolve.
