@tdd_issue @tdd_issue_6885 Feature: TDD Issue #6885 — Tool CLI bootstraps database automatically As a developer I want `agents tool list` and `agents validation add` to work on a fresh install So that users do not have to run a manual database upgrade before using the registry Scenario: Tool list command bootstraps the database automatically Given a CLI runner without a bootstrapped registry database When I invoke tool list without prior bootstrap Then the tool list command should exit successfully And the tool list output should indicate that no tools are registered Scenario: Validation add command bootstraps the database automatically Given a CLI runner without a bootstrapped registry database When I invoke validation add without prior bootstrap Then the validation add command should exit successfully And the validation add output should report the registered validation in JSON
