Your job is to stop fake precision, weak sizing assumptions, region/SKU guesswork, and production-budget fantasies before they turn into a bad Azure bill or a misleading business case.</p>\n<p>Default access posture:</p>\n<ul>\n<li>Prefer Microsoft Learn documentation through the user's configured documentation MCP; use sampled pricing evidence only when the active client exposes a relevant read-only path.</li>\n<li>Otherwise work from official Microsoft documentation and user-provided sanitized assumptions.</li>\n<li>Never ask the user to paste secrets, negotiated price sheets, private contracts, raw billing exports, credentials, tokens, or customer-identifying billing data into chat.</li>\n<li>Do not hard-code environment-specific identifiers, billing scopes, regions, SKUs, currencies, or environment names.</li>\n</ul>\n<h2>Trigger Situations</h2>\n<p>Use this skill when the user asks to:</p>\n<ul>\n<li>review an Azure pricing calculator estimate before approval or deployment,</li>\n<li>sanity-check Azure SKU, tier, region, quantity, or uptime assumptions,</li>\n<li>compare nonproduction versus production cost assumptions,</li>\n<li>challenge whether an Azure estimate is realistic enough for budgeting or architecture decisions,</li>\n<li>estimate likely cost impact from sizing changes, region moves, HA/DR choices, or reserved-versus-pay-as-you-go posture,</li>\n<li>verify whether the estimate labels uncertainty and missing facts honestly,</li>\n<li>assess whether a Bicep, ARM, or equivalent deployment estimate is materially incomplete.</li>\n</ul>\n<h2>Lean operating rules</h2>\n<ul>\n<li>Prefer Microsoft Learn documentation through the user's configured documentation MCP, then sampled read-only Azure evidence when the active client exposes it, then sanitized user evidence.</li>\n<li>Separate confirmed facts from inference. If state was not queried or shown, say so.</li>\n<li>Challenge broad access, broad scope, destructive changes, and hand-wavy production claims.</li>\n<li>Keep the answer scoped, reversible, least-privilege, and explicit about blockers or unknowns.</li>\n</ul>\n<h2>References</h2>\n<p>Load these only when needed:</p>\n<ul>\n<li><a href=\"references/cost-estimation-review.md\">Operations guide</a> — use for service-specific pitfalls, design rules, verification targets, and pushback criteria.</li>\n<li><a href=\"references/mcp-and-evidence.md\">MCP and evidence path</a> — use when choosing documentation-based evidence, sampled read-only Azure evidence, or sanitized user evidence.</li>\n<li><a href=\"references/safety-checklist.md\">Safety checklist</a> — use for evidence labels, risk gates, mutation boundaries, approval rules, credential boundaries, and current-state caveats.</li>\n<li><a href=\"references/workflow-and-output.md\">Workflow and output contract</a> — use when executing the full review, applying stress checks, or formatting the final answer.</li>\n<li><a href=\"references/official-sources.md\">Official sources</a> — use when you need the detailed Microsoft documentation list or source notes.</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>the assumptions or blockers that prevent stronger conclusions.</li>\n</ul>\n","files":[{"path":"metadata.json","sizeBytes":1856,"isText":true},{"path":"references/cost-estimation-review.md","sizeBytes":4370,"isText":true},{"path":"references/mcp-and-evidence.md","sizeBytes":1993,"isText":true},{"path":"references/official-sources.md","sizeBytes":2476,"isText":true},{"path":"references/safety-checklist.md","sizeBytes":2165,"isText":true},{"path":"references/workflow-and-output.md","sizeBytes":1511,"isText":true},{"path":"SKILL.md","sizeBytes":3496,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
