A jadpo toolchain command names an action it doesn't have, or a release that isn't kept.

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

Why Jadpo refuses it

jadpo toolchain lists the releases kept for projects, remove deletes one, and pin and unpin write the release a project runs with into jadpo.lock. Deleting is done to the version you name, never another.

What it looks like

The release named isn't kept:

shell
jadpo toolchain remove 0.0.9
jadpo toolchain

error Jadpo 0.0.9 isn't kept

reason
The cache holds only the releases projects needed, and this isn't one of them.
next
Run jadpo toolchain list to see the releases kept (agent)
rule
cli.toolchain_arguments
help
https://jadpo.dev/docs/errors/cli.toolchain_arguments

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

An action it doesn't have is refused with the ones it does:

shell
jadpo toolchain clean
jadpo toolchain

error clean isn't a toolchain action

reason
jadpo toolchain lists the kept releases, remove deletes one, and pin and unpin write the release a project runs with into jadpo.lock.
next
Use list, remove, pin or unpin (agent)
rule
cli.toolchain_arguments
help

How to fix it

If you meant a kept release, list them first, then remove one by its version:

shell
jadpo toolchain listjadpo toolchain remove <version>

A project that needs a removed release fetches it again when it runs.
