What problem does it solve? Teams adopting Google AI Studio Agents patterns risk unsafe setups: unmanaged tool access, open network egress, unbounded token loops, and unverified outputs. This Skill evaluates AGENTS.md and SKILL.md templates, tool allowlists, network restrictions, sandbox isolation, and termination conditions before any agent harness is considered ready. ## Core Features & Use Cases - Harness File Evaluation: Checks that AGENTS.md and SKILL.md persona and workflow templates are properly mounted. - Tool and Network Allowlisting: Validates explicit tool toggles and domain allowlists instead of all-tools-on or open egress. - Termination and Sandbox Checks: Enforces named stop conditions, worktree isolation, and verified execution with read-back before claiming done. - Use Case: Before deploying an agent workflow, run the harness script with your allowed tools, permitted domains, and stop condition; proceed only when every JSON check returns ok and the process exits 0. ## Quick Start Ask the AI to evaluate your agent harness by running scripts/studio_agent_harness.py with your AGENTS.md, SKILL.md, allowed tools, permitted domains, and stop condition, then confirm every check passes.
