Use the per-skill facts and sampled live evidence in <code>references/official-sources.md</code>; when the user has configured read-only AWS MCP access, use exposed read-only tools for current-state evidence instead of guessing.</li>\n<li>Separate confirmed facts from inference. If state was not queried or shown, say so.</li>\n<li>Challenge broad access, public exposure, destructive automation, untested recovery, hidden cost, and vague production claims.</li>\n<li>Keep the answer scoped, reversible, least-privilege, and explicit about blockers or unknowns.</li>\n<li>Load references only when needed; do not pull all deep guidance into short answers.</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 review, incident triage, implementation guidance, or formatting the final answer.</li>\n<li><a href=\"references/safety-checklist.md\">Safety checklist</a> — use before privileged, destructive, traffic-changing, cost-changing, compliance-impacting, or production-impacting recommendations.</li>\n<li><a href=\"references/official-sources.md\">Official sources</a> — use when grounding AWS service behavior or checking the detailed source list.</li>\n<li><a href=\"references/rds-aurora-performance-evidence.md\">RDS and Aurora Performance Evidence Guide</a> — use for domain-specific failure modes, safe workflow, verification targets, and pushback criteria.</li>\n</ul>\n<h2>Response minimum</h2>\n<p>Return, at minimum:</p>\n<ul>\n<li>the scoped target and evidence level,</li>\n<li>the main risks or control gaps,</li>\n<li>the safest next actions,</li>\n<li>validation or rollback notes where relevant,</li>\n<li>the assumptions or blockers that prevent stronger conclusions.</li>\n</ul>\n","files":[{"path":"metadata.json","sizeBytes":1240,"isText":true},{"path":"references/official-sources.md","sizeBytes":2026,"isText":true},{"path":"references/rds-aurora-performance-evidence.md","sizeBytes":3352,"isText":true},{"path":"references/safety-checklist.md","sizeBytes":1436,"isText":true},{"path":"references/workflow-and-output.md","sizeBytes":2230,"isText":true},{"path":"SKILL.md","sizeBytes":2864,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
