ubuntu-helm-validator

Validate Kubernetes Helm charts backed by Canonical Ubuntu OCI images (rocks). Wraps the helm-validator skill. Use when: validating a chart, linting templates, running dry-run, checking security defaults, verifying chart structure. Trigger phrases: "validate chart", "lint chart", "check chart", "helm lint", "dry-run chart", "security check chart".

Quality

Content

87%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.

Concise and highly actionable, with concrete commands and good structure delegating to real scripts. The main gap is workflow clarity: the batch test suites lack explicit failure-handling checkpoints and a final pass/fail verification step.

Suggestions

Add explicit failure-handling checkpoints after each test suite (e.g., 'If lint fails, review the errors, fix the templates, and re-run before proceeding to render-templates').

Add a final verification step that summarizes pass/fail status across all suites before declaring the chart validated.

Specify ordering/dependencies between the suites — e.g., require render-templates to pass before running OPA policy and unit tests against the rendered output.

DimensionReasoningScore

Conciseness

Lean and efficient — it assumes Claude's competence, never explaining what Helm, OPA, Spread, or rocks are, and every line provides actionable instruction rather than padding.

5 / 5

Actionability

Gives fully executable, copy-paste-ready commands — 'npx tessl i pantheon-ai/helm-toolkit@0.1.0', 'scripts/run-test.sh lint <chart-path>', 'command -v spread' — covering each test type with specific subcommands.

5 / 5

Workflow Clarity

The sequence (prerequisites → helm-validator → lint → render → policies → unit → conditional integration) is clear, but running multiple test suites is a batch operation with no failure-handling checkpoints or feedback loops, which caps this dimension at 3 per the rubric.

3 / 5

Progressive Disclosure

A short, well-organized body (<50 lines) with clear sections (Prerequisites, Instructions) that delegates tooling to real verified scripts (scripts/run-test.sh, scripts/setup.sh) rather than inlining their logic.

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, third-person description that concisely states the domain, lists several concrete actions, and supplies both a 'Use when' clause and explicit trigger phrases. It is specific, complete, and low conflict-risk.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions — 'validating a chart, linting templates, running dry-run, checking security defaults, verifying chart structure' — giving comprehensive coverage of the skill's capabilities.

5 / 5

Completeness

Explicitly answers both 'what' ('Validate Kubernetes Helm charts backed by Canonical Ubuntu OCI images') and 'when' ('Use when: validating a chart, linting templates...') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Provides comprehensive natural trigger phrases users would actually say — 'validate chart', 'lint chart', 'helm lint', 'dry-run chart', 'security check chart' — including synonyms across validate/lint/check.

5 / 5

Distinctiveness Conflict Risk

Occupies a clear niche (Helm charts on Canonical Ubuntu OCI images/rocks) with distinct triggers, so conflict with unrelated skills is minimal.
