The Agent Persona Explorer workflow measured tooling availability rather than recommendation quality when the Copilot CLI was missing — there was no documented path for this failure mode and no standard way to record tool-unavailable outcomes comparably across runs.
.github/aw/github-agentic-workflows.mdCopilot CLI not installed, timeout, empty response), and a four-step tool-unavailable fallback pattern (record structured outcome, derive inferred recommendation from reference files, publish aTooling Availabilitysection).github/aw/create-agentic-workflow.md.github/workflows/agent-persona-explorer.md"Are you available?") before running any scenario{ "status": "tool-unavailable", "reason": "..." }, derives inferred recommendations from.github/aw/*.md, skips agent invocations, sets quality score toN/A### Tooling Availabilityfield so tool-unavailable runs are structurally comparable to normal runs
