mise integration not working with mise activated and fnox not installed. #300

I tried to use the mise integration with mise 2026.2.23 and fnox and with mise activated in my shell.
I tried the example from the fnox doc:

[plugins]
fnox-env = "https://github.com/jdx/mise-env-fnox"

[tools]
fnox = "latest"

[env]
_.fnox-env = { tools = true }

I receive the following error when entering the directory where the .mise.toml is:

mise [fnox-env] [fnox] warning: `fnox config-files` failed: runtime error: Command failed with status exit status: 127: sh: fnox: not found

stack traceback:
        [C]: in field 'exec'
        ...local/share/mise/plugins/fnox-env/hooks/mise_env.lua:6: in function <...local/share/mise/plugins/fnox-env/hooks/mise_env.lua:5>
        [C]: in function 'pcall'
        ...local/share/mise/plugins/fnox-env/hooks/mise_env.lua:5: in upvalue 'get_config_files'
        ...local/share/mise/plugins/fnox-env/hooks/mise_env.lua:26: in function 'PLUGIN.MiseEnv'
        (...tail calls...)

Seems mise is ignoring the tools = true arg and call the plugin before the tool is installed.

You need to run mise install first so the fnox binary is available before the env plugin runs. hook-env does not auto-install tools.

If fnox is already installed and you're still seeing this error, try mise cache clear — the env cache may be stale.

I can’t install tools before entering the directory because that’s the actual goal of mise hooks to setup an env including all tools for a specific dir when entering it.
fnox doc (https://fnox.jdx.dev/guide/mise-integration.html#installation) specifically mentions using tools = true to solve this issue.

This error is now happening on the latest mise version even when the plugin is installed... Interestingly though, running mise env shows that the fnox env variables are being inserted into mise?

warning

mise all tools are installed
