A native Mac workshop for Claude Code - every session, chat, MCP and skill in a real interface instead of hand-edited JSON.
Every primitive - sessions, agents, loops, harnesses, hooks, skills, MCP, plugins - in one real interface. No hidden state, no config you can't see.
Run six side by side in one window - same binary, same files.
Build and route to custom agents - isolated context, per-agent model and tools.
Set a goal, a verifier and a turn budget; watch it run to a finish line.
Wrap long tasks in a disciplined cycle with a progress file and checkpoints.
Deterministic control at every event - toggle PreToolUse, Stop and more, no JSON.
Install, pin per project, or fork a skill into its own context.
Add, edit and toggle servers in a real UI instead of parsing JSON.
Browse marketplaces; bundle your setup to share with the team.
Every past chat indexed - find where you solved it the first time.
Rewind a session to any point; set model, dir and permissions per task.
Give Claude a goal it can check, a verifier to grade the work, and a turn budget so it can't run away. Atelier builds the loop, watches every turn, and stops at the finish line.
For longer work, wrap it in a harness - a plan → work → review cycle with a progress file and checkpoints, so a fresh context picks up exactly where the last left off.
Build custom agents - a reviewer, an explorer, a test runner - each with its own prompt, model and tool access. Atelier gives /agents a real editor.
Each runs in its own context and reports back a summary - the exploration noise never lands in your main session. Delegate the heavy work, keep your window clean.
Atelier drives the claude binary already on your machine, reads and writes the same files, and uses the auth you already set up.
No lock-in, no hidden state, no cloud middleman. Your config stays yours - you can still edit it by hand whenever you want.
Free for macOS. Windows and Linux are on the bench.
