What problem does it solve? When a project pins a vendored copy of the plumbline linter, its version can drift behind the version carried by the installed ok front-door plugin. This Skill surfaces both versions side by side so you can see whether the project lints at an older pinned version than the payload offers. ## Core Features & Use Cases - Dual version report: Runs the vendored binary at .ok-plumbline/bin/plumbline and the carried payload binary, printing each version on its own labeled line. - Drift detection: A mismatch between the two lines signals that the front door has moved ahead and the project has not yet converged. - Graceful absence handling: Reports none when the project has no vendored binary or when the ok front door is not installed on the machine, and explains the 0.0.0-unvendored placeholder stamped on unvendored payload copies. - Use Case: After updating the ok plugin, run /version in a project to confirm whether its pinned linting version still matches the newly carried payload before deciding to converge. ## Quick Start Invoke the /version slash command to print the project's vendored plumbline version next to the carried payload version.
