Property	Value
Best for	Exact signature plus AKS operation
Output	Cause, fix, and Learn citation

When to Use This Skill

Named catalog signatures only. Generic AKS → aks-troubleshooting; non-AKS → no AKS skill.

If every qualifier for a catalog row is not present, do not use this skill. This catalog has no quota-error rows; route AKS quota incidents to aks-troubleshooting.

MCP Tools

None required. Use advertised read-only Azure tools or CLI queries.

Workflow

Capture exact code, nested message, operation, and AKS resource.
Require every qualifier; codes are not substrings.
Give cause, fix, citation, and read-only verification.
State what ran; require explicit approval before every mutation.

Error Handling

Input	Response
Bare wrapper/number	Request nested signature and CSE context
Generic AKS	`aks-troubleshooting`
Non-AKS	No AKS skill

About this skill

Trigger

Lookup documented AKS fixes only when the prompt includes an exact catalog signature and all of its qualifiers: VMCannotFitEphemeralOSDisk; NodePoolMcVersionIncompatible; 'NodeImageVersion is not accepted'; AKS SkuNotAvailable with size, location, and zone; ZonalAllocationFailed with insufficient zone capacity; OverconstrainedAllocationRequest with listed constraints; nested AKS vmssCSE/CSE VMExtensionError_OutboundConnFail, VMExtensionError_K8SAPIServerConnFail, or VMExtensionError_K8SAPIServerDNSLookupFail; or AllocationFailed with the full cataloged internal-error or insufficient-regional-capacity message. Never use for quota errors, code-only or bare wrappers, generic symptoms, incomplete signatures, or failures outside AKS; use aks-troubleshooting or azure-diagnostics.

How this issue was made

Source

github.com/microsoft/azure-skills, branch main, last pushed 6 November 2026.

Licence

MIT — the text of every skill is reproduced unmodified, frontmatter included, under the upstream licence.

Discovery

53 skills found by walking the repository tree for SKILL.md, not by matching a directory convention. 11 distinct layouts observed: .github/plugins/aks-skills/skills/*/SKILL.md, .github/plugins/azure-advisor/skills/*/SKILL.md, .github/plugins/azure-cost/skills/*/SKILL.md, .github/plugins/azure-kusto-graph-skills/skills/*/SKILL.md, .github/plugins/azure-local-skills/skills/*/SKILL.md, .github/plugins/foundry-iq-skills/skills/*/SKILL.md, skills/*/SKILL.md, skills/azure-kubernetes/*/SKILL.md, skills/microsoft-foundry/*/SKILL.md, skills/microsoft-foundry/models/deploy-model/*/SKILL.md, skills/microsoft-foundry/models/*/SKILL.md.

Duplicates collapsed

35 mirror copies folded into their canonical skill — republished for GitHub. Copies match on content hash and on position once a leading per-agent prefix is stripped, because the same skill is routinely shipped under a dozen agent directories with a dozen different hashes.

Issue colours

Resolved from a curated brand profile — hue 251°, chroma 0.167. Two accent tones are generated per issue and each is proven against its own ground before it ships: a single accent that passes AA on both light and dark paper is arithmetically impossible.

Heading repairs

1 repair applied to this skill so the document has one h1 and no skipped levels:

Removed “AKS Known Issues”, a leading h1 that duplicated the skill title.

Spec compliance

Every skill satisfies the Agent Skills specification’s frontmatter rules.

Images

Images inside a skill come from the upstream repository. Where the author gave no alternative text we mark the image decorative rather than inventing a description — a plausible caption we made up is worse than none for the reader who depends on it.

Marketplace

A plugin manifest is published at .claude-plugin/marketplace.json by Microsoft, declaring 7 plugins. It is read for editorial metadata only — never as the skill index, which is always the repository tree.

Signal

Install counts come from skills.sh. They measure downloads, not quality, and an unranked repository is not an unread one.

Agent surfaces

The whole issue is available as one markdown document at /microsoft/azure-skills.md, and each skill at its own .md URL.

Publication

Set by Skills Docs from the source repository. Body text is Literata at the reader’s chosen size and measure; code is Geist Mono. Nothing on this page was written by us except this paragraph.
