cluster-creator

End-to-end OpenShift cluster creation using Red Hat Assisted Installer. Handles Single-Node OpenShift (SNO) and HA multi-node clusters on baremetal, vsphere, oci, nutanix. Use when: - "Create a new OpenShift cluster" - "Install OpenShift on my servers" - "Set up a single-node cluster for edge deployment" - "Deploy a production HA cluster" Complete workflow: cluster definition, ISO generation, host discovery/validation, role assignment, network configuration (VIPs, static networking), installation monitoring, credential retrieval. NOT for: - Listing existing clusters → Use `/cluster-inventory` skill - Modifying running clusters → Out of scope (Day-2 operations require direct cluster access) - Cluster upgrades (not yet supported)

77%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A thorough, well-sequenced workflow for an inherently complex, destructive operation, with strong validation checkpoints and excellent progressive disclosure into a real reference bundle. Its main weakness is conciseness — prerequisite/tool/scope information is duplicated across several sections and could be consolidated.

Suggestions

Consolidate the MCP tools list, which currently appears in allowed-tools, the Prerequisites 'Required MCP Tools' block, and the Dependencies 'Required MCP Tools' block — keep a single authoritative list and reference it.

Merge the repeated cluster-type scope / 'NOT for' guidance (Prerequisites, Step 2 context, and 'When to Use This Skill') into one location to avoid stating it three times.

Inline the exact credential-retrieval tool call in Step 17 rather than deferring entirely to 'Follow download procedure' in credentials-management.md, so the common case is executable without a reference hop.

DimensionReasoningScore

Conciseness

The core 18-step workflow is lean and instructional, but the same information is repeated: the MCP tools list appears three times (frontmatter, Prerequisites, Dependencies) and the cluster-type scope / NOT-for guidance is restated two to three times, so it could be tightened by consolidation. Not below 3 because there is no padding explaining concepts Claude already knows; not above 3 because the duplication is more than minor.

3 / 5

Actionability

Highly concrete where it counts — a copy-paste bash block with a URL allowlist guard and curl safety flags, plus explicit tool + parameter blocks (e.g. create_cluster {name, version, base_domain, single_node, platform, cpu_architecture, ssh_public_key}) — but a few steps defer exact commands to reference docs ('Follow download procedure' in credentials). Not 5 because not every common case is spelled out inline; not 3 because the inline guidance is genuinely executable.

4 / 5

Workflow Clarity

A clearly sequenced 18-step process with explicit validation checkpoints (Steps 5 and 13 marked CRITICAL), feedback loops ('fix/wait/abort', error → consult troubleshooting → retry/abort), and a task checklist; the destructive-operation validation cap does not apply because validation is extensive (prereqs, host-count SNO=1/HA≥3, cluster readiness, irreversible-start warning).

5 / 5

Progressive Disclosure

The body is an overview that delegates detail via well-signaled one-level-deep references (troubleshooting.md, networking.md, input-validation-guide.md, providers.md, host-requirements.md, credentials-management.md, etc.), all of which exist in references/, organized into a categorized 'Reference Documentation' section plus an INDEX.md hub — matching the 'clear overview with well-signaled one-level-deep references' anchor.

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, well-structured description that concisely states what it does, when to use it with natural trigger phrases, supported platforms, and explicit out-of-scope boundaries. It cleanly matches the top anchors across all four dimensions and uses third-person voice throughout.

DimensionReasoningScore

Specificity

Names the domain and a comprehensive set of concrete actions ('cluster definition, ISO generation, host discovery/validation, role assignment, network configuration (VIPs, static networking), installation monitoring, credential retrieval') plus supported platforms, matching the 'multiple specific concrete actions; comprehensive coverage' anchor.

5 / 5

Completeness

Explicitly answers 'what' ('End-to-end OpenShift cluster creation using Red Hat Assisted Installer') and 'when' (a 'Use when' block with concrete trigger phrases) plus a 'NOT for' boundary, matching the anchor that requires both with concrete triggers.

5 / 5

Trigger Term Quality

Four natural trigger phrases a user would actually say ('Create a new OpenShift cluster', 'Install OpenShift on my servers', 'Set up a single-node cluster for edge deployment', 'Deploy a production HA cluster') cover the main action verbs and cluster types; not below 5 since no natural variations are meaningfully omitted for this domain.

5 / 5

Distinctiveness Conflict Risk

Clear niche (self-managed OpenShift creation via Assisted Installer) with explicit redirects to the sibling skill ('Listing existing clusters → Use /cluster-inventory'), giving minimal conflict risk.
