How to Run
Start the dev server:
npm start
# Visit http://localhost:8888
Run all tests:
npm test
Run KidLisp tests:
npm run test:kidlisp
# Or filter: npm run test:kidlisp -- --filter=<spec-name>
Development Environment
Terminal Workflow (IMPORTANT):
- Use Emacs MCP + fishy terminal for all command execution
- DO NOT use Bash tool for running commands - use fishy via Emacs MCP instead
- The fishy terminal (
π-fishy) is the primary shell for all development commands
Emacs Terminal Buffers:
The development environment uses Emacs with named terminal buffers. Use Emacs MCP tools (mcp_emacs_*) to interact with them:
π-fishyβ Main fish shell (use this for all commands!)π-siteβ Site/web server logsπ-sessionβ Session server logsπ§ͺ-kidlispβ KidLisp test runnerπ΄-redisβ Redis logsπ-topβ System monitoringπ-tunnelβ Tunnel logs- (See AGENTS.md.backup for full list)
How to run commands in fishy:
- Use
mcp_emacs_emacs_switch_bufferto switch toπ-fishy - Use
mcp_emacs_emacs_send_keysto send the command - Send newline to execute

Host Access (Docker)
When running inside a Docker container on Jeffrey's MacBook (or any local Docker host), SSH to the host machine via:
ssh jas@host.docker.internal
- "SSH into my macbook" or "SSH into my host" means: connect to
host.docker.internalfrom within the container ac-hostlists all machines fromvault/machines.jsonand can SSH to them- The host machine resolves via
host.docker.internalβ do NOT use the LAN IP from machines.json when running in Docker
