toolchain.project_not_found

On this page

You ran a command that works on a project in a folder with no app.jadpo, in it or in any folder above it.

Area 14, Tools; not declinable; the next step is usually the agent's.

Why Jadpo refuses it

A project is the folder that holds app.jadpo, and commands such as jadpo check, jadpo test and jadpo config work on a whole project. Run from a folder inside it, they find it by looking up through the folders above. When none holds app.jadpo, there is no project to work on, and the command does nothing.

What it looks like

jadpo check, run in a folder that holds no project:

shell
jadpo check
jadpo check

error No Jadpo project here

reason
Jadpo looks for app.jadpo in this folder and every folder above it, and found none.
next
Run jadpo check inside a project, or give a file or folder: jadpo check <path> (agent)
rule
toolchain.project_not_found
help
https://jadpo.dev/docs/errors/toolchain.project_not_found

(agent) at the end of the next: line means your coding agent can make the fix itself.

How to fix it

If the project is in another folder, run the command there, or give its path:

shell
jadpo check todo-app

The command checks the project in todo-app.

If there is no project yet, make one:

shell
jadpo new todo-app
output
Created todo-app    jadpo  X.Y    route  POST /hello    files  14 writtennext: cd todo-app && jadpo dev  serves it on http://localhost:3000

cd todo-app, and every command finds the project from there.
