Questions & Answers

As answered by people managing OpenAI Codex CLI and Session Orchestrator.

How would you describe the primary audience of your product?

Session Orchestrator's answer:

One developer running Claude Code, Codex CLI, Cursor or Pi on their own repositories. It protects your own concurrent sessions, not a shared team workspace.

What makes your product unique?

Session Orchestrator's answer:

Each agent gets a declared list of files it may change, and overlapping lists are rejected before dispatch. A guard blocks 12 destructive command patterns, tests and typecheck run after each implementation wave, and STATE.md lets the next session resume where the last one stopped.

Why should a person choose your product over its competitors?

Session Orchestrator's answer:

Choose it if you want your existing agent to follow an agreed plan rather than switch to a new agent. It runs on top of Claude Code, Codex CLI, Cursor or Pi, drives issues on GitLab and GitHub, and keeps everything as plain text in your repository with no build step, account or server. Learnings only become rules after you approve them. Measured comparisons with other orchestrators are in docs/components.md.

What's the story behind your product?

Session Orchestrator's answer:

Bernhard Götzendorfer kept 20 to 30 prompts in a Notion page and, before each session, copied the right one and explained his way of working again. That routine gradually became Plan, Go, Close, which he now uses on his own Macs. Session Orchestrator is the tool that grew out of it.

Which are the primary technologies used for building your product?

Session Orchestrator's answer:

Skills, commands and agents are Markdown files with YAML frontmatter. The code that dispatches, validates and records runs as Node.js ES modules on Node.js 24 or later, with no build step. Tests run on Vitest. It installs through the Claude Code plugin marketplace, npm for Pi, or an installer script for Codex CLI and Cursor.
