The evidence supports product-context gates for agent PRs, automated audits for execution-based benchmarks, and staged serverless migration checks that keep generated code and infrastructure aligned. ## Decision-compliance checks for coding-agent pull requests Product and engineering teams should add a decision-compliance check to agent-authored PRs when required behavior lives outside the repository. The check can turn product decisions into task-level acceptance criteria covering approved UI components, auth wrappers, feature flags, audit logging, ORM choices, and deprecated patterns. A lightweight scorer can inspect git diffs with regex checks, then route uncertain cases to human review. The reason to test this now is practical: codebase access alone can miss decisions stored in specs, wikis, product tools, or audit documents. In Context-Augmented Code Generation, Claude Code with codebase access reached 46% weighted decision compliance on 8 Next.js tasks. Adding Brief, which retrieved recorded decisions and guided spec generation and mid-build consultation, raised compliance to 95%, eliminated blocking violations, and produced merge-ready results on all 8 tasks in the study. A local pilot could use 10 recent tickets with known cross-document requirements. Run the same agent once with repository access only and once with retrieved decisions plus acceptance criteria. Compare blocking violations, deprecated pattern use, tests added, and reviewer rework. The published result is small and clean-room, so the local test should focus on whether the team’s own hidden rules are being followed. ### Sources - [Context-Augmented Code Generation: How Product Context Improves AI Coding Agent Decision Compliance by 49%](../Inbox/2026-04-27--context-augmented-code-generation-how-product-context-improves-ai-coding-agent-decision-compliance-by-49.md): Defines decision compliance, reports 46% to 95% improvement with Brief, and lists the workflow and benchmark limits. - [Context-Augmented Code Generation: How Product Context Improves AI Coding Agent Decision Compliance by 49%](../Inbox/2026-04-27--context-augmented-code-generation-how-product-context-improves-ai-coding-agent-decision-compliance-by-49.md): Explains why team decisions in product tools and wikis are invisible to codebase-only agents. ## Automated artifact audits for execution-based agent benchmarks Benchmark maintainers and teams running internal agent evaluations should add an audit step before using scores for model selection. The audit should compare each task’s instruction, reference program, evaluator script, and environment configuration, then flag contradictions such as underspecified outputs, evaluator logic that rejects valid answers, broken reference code, and environment assumptions. BenchGuard gives a concrete template for this workflow. It checks the full task artifact stack with a structured LLM audit, deterministic static checks, and optional agent programs or execution logs. On ScienceAgentBench, it found 12 author-confirmed defects across 102 tasks. On BIXBench Verified-50, a five-model audit exactly matched 20 of 24 expert-identified atomic issues and partially matched 23 of 24. The reported audit cost was $14.38 for 50 BIXBench tasks and $22.72 for 102 ScienceAgentBench tasks in definition-only mode. The adoption path is small: run the audit on a 50-task slice of any execution benchmark used in procurement, regression testing, or leaderboard reporting. Fix fatal task errors and evaluator mismatches first, then rerun the affected model comparisons. This protects teams from selecting tools based on broken tests. ### Sources - [BenchGuard: Who Guards the Benchmarks?

For a monolith-to-serverless migration, a static-analysis report should capture HTTP entry points, file ownership, call edges, asynchronous behavior, and schema candidates. A separate architecture artifact should map endpoints to Lambda functions and cloud resources before any Lambda handlers or AWS SAM templates are generated. Mono2Sls shows this pattern in a narrow but useful setting: Flask and Express applications migrated into AWS SAM applications. Its pipeline writes `analysis_report.json`, then `blueprint.json`, then Lambda code and `template.yaml`, followed by 11 cross-artifact consistency checks. On 6 benchmark applications with 10,478 lines of code and 76 observable business endpoints, it reported 100% deployment success without manual fixes, 66.1% end-to-end correctness, and 98.7% API-coverage F1. The ablation study attributed 23.4 percentage points of end-to-end correctness to static-analysis-guided architecture planning. A team can test the approach on one low-risk internal service by asking the agent to produce these artifacts and by failing the run when routes, handlers, IAM resources, DynamoDB tables, or SAM declarations disagree. The first success criterion should be deployability and API coverage, followed by business-behavior tests. ### Sources - [Mono2Sls: Automated Monolith-to-Serverless Migration via Multi-Stage Pipeline with Static Analysis](../Inbox/2026-04-27--mono2sls-automated-monolith-to-serverless-migration-via-multi-stage-pipeline-with-static-analysis.md): Lists Mono2Sls stages, extracted facts, cross-artifact checks, benchmark size, deployment success, correctness, and API coverage. - [Mono2Sls: Automated Monolith-to-Serverless Migration via Multi-Stage Pipeline with Static Analysis](../Inbox/2026-04-27--mono2sls-automated-monolith-to-serverless-migration-via-multi-stage-pipeline-with-static-analysis.md): Explains the need to align function boundaries, API definitions, handler implementations, and infrastructure declarations across generated artifacts.
