Analyze a failed Azure DevOps PR build by reusing the binlog that build already produced — instead of rebuilding locally. Use when an azure-pipelines check on a GitHub PR transitions to failure and you need a structured root-cause analysis posted back as a PR review. Downloads PostBuildLogs_* / Logs_Build_* from the AzDO build artifacts, invokes the binlog MCP server (Microsoft.AITools.BinlogMcp) for build overview / errors / warnings (with deeper diagnostic capabilities — root-cause reports, property-value tracing — when the basics aren't enough), groups symptoms by root cause, and emits a single summary comment. Optionally attaches inline suggestion blocks when an error maps to a one-line fix on a diffed line. Cuts per-PR analysis cost from ~5–8 min (rebuild + analyze) to ~2–3 min (download + analyze). DO NOT USE FOR: pipelines that don't publish a binlog artifact, GitHub-Actions-only repos (no AzDO build to reuse), or general CI health dashboards (use ci-analysis).
