gitops-cluster-debug

Debug and troubleshoot Flux CD on live Kubernetes clusters (not local repo files) via the Flux MCP server — inspects Flux resource status, reads controller logs, traces dependency chains, and performs installation health checks. Use when users report failing, stuck, or not-ready Flux resources on a cluster, reconciliation errors, controller issues, artifact pull failures, image automation not updating tags, alerts or webhooks not being delivered, or need live cluster Flux Operator troubleshooting.

Quality

Content

100%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 lean, highly actionable debugging skill with clearly sequenced workflows, explicit validation checkpoints and feedback loops, and well-signaled one-level-deep references all verified to exist.

DimensionReasoningScore

Conciseness

The body assumes Claude's Kubernetes/Flux competence throughout — no 'what is a HelmRelease' padding — and stays procedural; the only bulk is a functional CRD lookup table that explicitly directs grep-by-prefix instead of reading whole files.

5 / 5

Actionability

Every workflow names exact MCP tools (get_flux_instance, get_kubernetes_resources, get_kubernetes_logs, apply_kubernetes_manifest) and precise field paths (chartRef/sourceRef, valuesFrom, .spec.suspend, .spec.git.push.branch, $imagepolicy markers), giving fully executable guidance.

5 / 5

Workflow Clarity

Seven numbered workflows plus an installation check are clearly sequenced with explicit validation gates ('verify the exact field names and nesting', 'Verify the FluxInstance reports Ready: True') and feedback loops (failing managed resources → logs → RCA); the destructive apply path carries a 'do not apply unless explicitly requested' guard, so the batch/destruction cap does not bind.

5 / 5

Progressive Disclosure

SKILL.md is a clean overview pointing one level deep to references/flux-crds.md and references/troubleshooting.md (both verified present) plus per-CRD field-index files in assets/schemas/ (all 18 verified present), with a dedicated 'Loading References' section signaling when to load each.

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 tightly written description with concrete actions, comprehensive natural-language triggers, both 'what' and 'when' explicitly answered, and a clear distinctive niche, all in third-person voice.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'inspects Flux resource status, reads controller logs, traces dependency chains, and performs installation health checks' — giving comprehensive coverage rather than the 1-2 actions of the score-4 anchor.

5 / 5

Completeness

Explicitly answers 'what' (the four inspection/tracing/health-check actions) and 'when' ('Use when users report failing, stuck, or not-ready Flux resources...') with concrete trigger phrases, matching the score-5 anchor exactly.

5 / 5

Trigger Term Quality

The 'Use when users report...' clause enumerates natural user phrases (failing/stuck/not-ready resources, reconciliation errors, artifact pull failures, image automation not updating tags, alerts or webhooks not being delivered) with broad synonym coverage.

5 / 5

Distinctiveness Conflict Risk

The Flux-CD-on-live-clusters-via-Flux-MCP niche is sharply scoped and even disambiguates from local-repo work ('not local repo files'), giving minimal overlap with other skills.
