helm-chart-builder

Helm chart development agent skill and plugin for Claude Code, Codex, Gemini CLI, Cursor, OpenClaw — chart scaffolding, values design, template patterns, dependency management, security hardening, and chart testing. Use when: user wants to create or improve Helm charts, design values.yaml files, implement template helpers, audit chart security (RBAC, network policies, pod security), manage subcharts, or run helm lint/test.

Quality

Content

78%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.

The body is a highly actionable, opinionated checklist-driven skill with executable template patterns and validation commands, and it commendably avoids tutorial filler. Its main weaknesses are its monolithic structure — no reference files, and referenced scripts missing from the bundle — plus some redundant trigger/proactive sections and missing error-recovery loops in the workflows.

Suggestions

Move the Template Patterns, Values Design Principles, and Dependency Management sections into one-level-deep reference files (e.g., references/templates.md, references/values-design.md) and keep SKILL.md as a workflow overview with clearly signaled links, per progressive disclosure.

Ship the referenced scripts (scripts/chart_analyzer.py, scripts/values_validator.py, scripts/convert.sh) in the bundle or remove the Tooling and Installation sections that depend on them — currently the skill instructs Claude to run files that do not exist.

Add explicit feedback loops to the workflows (e.g., after helm lint/chart_analyzer findings, fix and re-run until clean before proceeding) and cut the duplicated 'When This Skill Activates' and 'Proactive Triggers' content, which repeats the frontmatter description and the review/security tables.

DimensionReasoningScore

Conciseness

The body is mostly dense, decision-oriented checklists and copy-paste templates with almost no tutorial padding ("Not a Helm tutorial — a set of concrete decisions"). It falls short of score 5 because of trimmable redundancy: the "When This Skill Activates" section restates the frontmatter description's triggers, "Proactive Triggers" reiterates rows already in the review/security tables, and the Installation/Related Skills sections are off-task for skill operation.

4 / 5

Actionability

Guidance is fully executable: complete copy-paste-ready templates for _helpers.tpl labels, conditional Ingress, and a security-hardened pod spec, plus concrete CLI invocations with flags ("python3 scripts/chart_analyzer.py mychart/ --output json", "helm lint mychart/", "helm template mychart/ --debug") and severity-rated fix tables. Score 5 rather than 4 because the examples cover the common cases end-to-end with no pseudocode.

5 / 5

Workflow Clarity

Each command has a clearly numbered sequence, and /helm:create ends in explicit validation (chart_analyzer.py, helm lint, helm template) while review/security use structured severity checklists. It stops short of score 5 because there is no explicit error-recovery feedback loop (what to do when lint/analyzer findings fail) and the review/security workflows produce a report without a re-check step.

4 / 5

Progressive Disclosure

The file is well-sectioned and navigable, but everything lives inline in a single ~450-line SKILL.md — the Template Patterns, Values Design Principles, and Dependency Management sections are exactly the deep material that belongs in one-level-deep reference files, and no references/ or scripts/ bundle files exist despite the body citing scripts/chart_analyzer.py, scripts/values_validator.py, and scripts/convert.sh. This fits the score-3 anchor (some structure, content that should be separate is inline) better than score 2, since section headers make it navigable and the structure itself is good.

Description

92%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 description: it pairs a comprehensive, concrete capability list with an explicit and specific "Use when" trigger clause, and it is written in third-person voice. The only weakness is a few missing natural synonyms (e.g., "Kubernetes" packaging) that keep trigger coverage just short of comprehensive, and a slightly buzzwordy opening clause about supported agent tools.

DimensionReasoningScore

Specificity

The description enumerates multiple concrete, specific actions spanning the full chart lifecycle: "chart scaffolding, values design, template patterns, dependency management, security hardening, and chart testing". Coverage is comprehensive with no noticeable gaps, matching the anchor for multiple specific concrete actions rather than the score-4 anchor (which requires minor gaps).

5 / 5

Completeness

It explicitly answers both questions: the "what" is the concrete capability list, and the "when" is a fully spelled-out "Use when: user wants to create or improve Helm charts... or run helm lint/test" with concrete trigger phrases. This mirrors the score-5 example structure exactly; score 4 would require a less explicit or less specific "when" clause.

5 / 5

Trigger Term Quality

Natural trigger terms are strong and include real user phrasing plus file/command names: "create or improve Helm charts, design values.yaml files, implement template helpers, audit chart security (RBAC, network policies, pod security), manage subcharts, or run helm lint/test". It falls short of score 5 because a few natural synonyms are missing — notably "Kubernetes", Chart.yaml, and generic phrases like "package Kubernetes manifests" — while clearly exceeding the score-3 anchor (some keywords, missing variations).

4 / 5

Distinctiveness Conflict Risk

The Helm-chart niche is unambiguous and its triggers (values.yaml, subcharts, helm lint/test, RBAC for charts) are unlikely to fire for any other skill. Only trivial overlap risk exists with generic DevOps skills, matching the clear-niche/minimal-conflict anchor rather than the minor-overlap score-4 anchor.
