slint package ' ' outside of the repository?

Error message

slint package '{}' outside of the repository?

What it means

In check_dependencies, every dependency named `slint*` or `i-slint*` inside repository crates must be declared with a `path` to an in-repo crate (plus the pinned version). A CargoDependency::Full entry with an empty path means the dependency resolves from crates.io instead of the local workspace, which would mix released and in-development slint versions. The check rejects this with a rhetorical 'outside of the repository?' message.

Solutions

1. Add the `path` key pointing at the local crate, e.g. `slint = { version = "=1.x.y", path = "../../api/rs/slint" }`.
2. If the dependency genuinely is external, use `CargoDependency::Workspace` (workspace inheritance) rather than a version-only entry.
3. Check whether the dependency should be listed under `[dependencies]` at all, or whether it belongs in the workspace root's dependency table.

Example fix

// before
slint = "1.8"
// after
slint = { version = "=1.8.0", path = "../../api/rs/slint" }

const dep = toml.parse(fs.readFileSync('Cargo.toml')).dependencies.slint;
if (typeof dep === 'string' || !dep.path) throw new Error('slint dep needs a path');

When it happens

Trigger: Adding `slint = "1.x"` (version-only, no `path`) to a Cargo.toml of a crate that the license/Cargo.toml xtask check covers; copying a dependency line from the published slint examples into an internal crate.

Common situations: Adding a new example or tool crate and pasting the crates.io dependency snippet from docs; forgetting that internal crates must use path + version; an edit that dropped the `path = "..."` key during refactoring.
