Conciseness

The body assumes Claude's competence throughout — no concept explanations, one-line section directives ("Commands to confirm the fix worked."), tersely labeled commands, and one-liner mistake entries. Every token earns its place, matching the lean anchor rather than the 'minor over-explanation' level below.

Actionability

The timeline mode is fully copy-paste ready ("kubectl get events -A --sort-by='.lastTimestamp' | tail -50", the custom-columns restart count sort, "flux get all -A | grep -v True") and the main structure gives specific directives ("include namespace flags, resource names from the description, and output filters"; "Show before and after"). Not 5 because the primary debug path supplies instructional scaffolding only — no example evidence commands per layer.

Workflow Clarity

The main flow is a clear six-step sequence (classify → evidence → hypothesis → fix → validation → rollback) with explicit validation and a rollback error-recovery path, and the timeline mode is numbered step-by-step. Not 5 because mode dispatch is implicit — the argument-hint promises "[timeline <minutes>|symptom]" but the body never explains how to select the timeline mode from $ARGUMENTS — and there is no re-validation loop after rollback.

Progressive Disclosure

Well-organized with clear section headers and no nested or buried references (the skill ships no bundle files). Not 5 because the ~60-line timeline mode is inlined content that could live in a separate reference file for a 130-line skill, and the closing "Next" pointer references "/platform-skills:debug" (a self-reference) and "/platform-skills:product postmortem" (external to this bundle) without explanation.

Specificity

"classifies the problem layer", "collects evidence", "forms a root-cause hypothesis", and "proposes a fix with validation and rollback steps" list multiple concrete, distinct actions in third person that comprehensively cover the troubleshooting workflow, matching the top anchor rather than the 'minor gaps' level below.

Completeness

The 'what' is clear and multi-part, but there is no 'Use when...' clause or equivalent explicit trigger guidance (only weakly implied by "troubleshooting"), which per the judging guidelines caps completeness at 3. Not 4 because the 'when' is not merely underspecified — it is absent.

Trigger Term Quality

"troubleshooting", "root-cause", and "fix" are natural terms, but the description omits the phrases users would actually say — "debug", "error message", "broken", "incident" — and none of the platform names (Kubernetes, Terraform, Flux, AWS) the skill covers, matching the 'some relevant keywords but missing common variations' anchor.

Distinctiveness Conflict Risk

"Structured platform troubleshooting" narrows the domain somewhat, but no platforms or tooling are named, so it would collide with any generic debugging or troubleshooting skill rather than only closely related ones.
