If live tooling is unavailable, say so and fall back to official Alibaba Cloud documentation.</li>\n<li>Separate confirmed facts from inference. Label each finding explicitly.</li>\n<li>RAM role binding to FC functions is mandatory — AccessKey ID/Secret in function environment variables is a critical security finding that blocks production approval.</li>\n<li>Never ask for AccessKey IDs, function environment variable values containing secrets, or customer data.</li>\n<li>Distinguish FC3 (v3) from FC2 (v2) before giving recommendations — the invocation models differ fundamentally.</li>\n</ul>\n<h2>Key serverless production readiness guidance</h2>\n<ul>\n<li><strong>FC3 cold start</strong>: cold start duration varies by runtime (Node.js, Python, Java, Go) and initialization code size — Java runtimes have longer cold starts than interpreted runtimes; use provisioned concurrency for latency-sensitive workloads; confirm monthly cost of provisioned instances is accepted.</li>\n<li><strong>VPC binding</strong>: FC3 functions require VPC binding to access private RDS, Redis (Tair), or internal service endpoints; VPC binding adds approximately 100ms to cold start latency; confirm this overhead is within SLA budget.</li>\n<li><strong>RAM role binding</strong>: FC3 functions should be assigned a RAM role with least-privilege permissions; AccessKey ID/Secret hardcoded in environment variables or function code are accessible to anyone with <code>fc:GetFunction</code> permission — treat as a critical finding.</li>\n<li><strong>SAE resource limits</strong>: SAE applications without memory and CPU limits allow resource contention across all applications in the same namespace; set explicit limits on every application in production namespaces.</li>\n<li><strong>ARMS tracing</strong>: ARMS distributed tracing must be enabled for all production FC and SAE services; without it, cross-service latency attribution and error root cause analysis requires log correlation, which is significantly slower.</li>\n<li><strong>FC2 vs FC3</strong>: FC2 uses trigger-based invocation with event objects; FC3 uses HTTP-first invocation with standard HTTP request/response; migration requires code refactoring — do not assume backward compatibility.</li>\n</ul>\n<h2>References</h2>\n<p>Load these only when needed:</p>\n<ul>\n<li><a href=\"references/workflow-and-output.md\">Workflow and output contract</a> — use when executing the full production readiness review or formatting the final assessment output.</li>\n<li><a href=\"references/official-sources.md\">Official sources</a> — use when grounding Alibaba Cloud service behavior or product feature claims.</li>\n</ul>\n<h2>Response minimum</h2>\n<p>Return, at minimum:</p>\n<ul>\n<li>the cold start and provisioned concurrency configuration assessment,</li>\n<li>VPC binding and private network access review,</li>\n<li>RAM role and credential hygiene verdict (PASS/FAIL),</li>\n<li>memory, CPU, and concurrency limits review,</li>\n<li>ARMS tracing and observability coverage,</li>\n<li>security group and network access findings,</li>\n<li>production readiness verdict with explicit blockers.</li>\n</ul>\n","files":[{"path":"metadata.json","sizeBytes":1317,"isText":true},{"path":"references/official-sources.md","sizeBytes":1225,"isText":true},{"path":"references/workflow-and-output.md","sizeBytes":3403,"isText":true},{"path":"SKILL.md","sizeBytes":4377,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
