What problem does it solve? Validating the flagship GAIA agent is error-prone: plausible answers can hide missing tools, concurrent TUI instances corrupt each other's state, and test runs can pollute the user's real memory database. This Skill provides a proven methodology for driving the agent through the TUI and verifying results against ground truth. ## Core Features & Use Cases - Capability Ladder: A seven-rung test sequence (L1-L7) from basic arithmetic through skill loading to real GitHub triage, with pass conditions and reference timings for each rung. - Environment Isolation: Mandatory launcher configuration using GAIA_TUI_HOME, GAIA_MEMORY_DB, and GAIA_AGENT_LOG to prevent cross-session contamination and protect user data. - Permission Gate Verification: Checks that gh commands land in the correct ALLOW/CONFIRM/REFUSE tiers, including rendered-frame inspection of confirmation modals. - Use Case: After merging feature branches into the TUI, run the ladder to catch regressions like broken Enter handling that unit tests miss, then verify skill tool registration against the agent log. ## Quick Start Ask the agent to run the capability ladder against the GAIA TUI and verify each rung's output against ground truth from the gh CLI.
