Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 5 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00029 | $0.07747 |
| Opus 5 | $0.00015 | $0.03874 |
| Sonnet 5 | $0.00006 | $0.01549 |
| Haiku 4.5 | $0.00003 | $0.00775 |
Grade A, and why
k8s-yaml-validator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Kubernetes YAML Validator
Overview
This skill provides a comprehensive validation workflow for Kubernetes YAML resources, combining syntax linting, schema validation, cluster dry-run testing, and intelligent CRD documentation lookup. Validate any Kubernetes manifest with confidence before applying it to the cluster.
IMPORTANT: This is a REPORT-ONLY validation tool. Do NOT modify files, do NOT use Edit tool, do NOT use AskUserQuestion to offer fixes. Generate a comprehensive validation report with suggested fixes shown as before/after code blocks, then let the user decide what to do next.
Trigger Phrases
Use this skill when prompts look like:
- "Validate this Kubernetes YAML before deploy."
- "Lint these manifests and report what is broken."
- "Check this CRD manifest and explain schema issues."
- "Run dry-run checks on this manifest."
- "Find line-level errors in this multi-document YAML."
When to Use This Skill
Invoke this skill when:
- Validating Kubernetes YAML files before applying to a cluster
- Debugging YAML syntax or formatting errors
- Working with Custom Resource Definitions (CRDs) and need documentation
- Performing dry-run tests to catch admission controller errors
- Ensuring YAML follows Kubernetes best practices
- Understanding what validation errors exist in manifests (report-only, user fixes manually)
- The user asks to "validate", "lint", "check", or "test" Kubernetes YAML files
Read-Only Boundary (Mandatory)
This skill is strictly report-only:
- Do NOT modify any user files.
- Do NOT run Edit for fixes.
- Do NOT ask for permission to apply fixes.
- Do provide before/after snippets as suggestions in the report.
Deterministic Path Setup
Run with explicit paths so commands are repeatable:
REPO_ROOT="$(git rev-parse --show-toplevel 2>/dev/null)"
SKILL_DIR="$REPO_ROOT/devops-skills-plugin/skills/k8s-yaml-validator"
TARGET_FILE="$REPO_ROOT/<relative/path/to/file.yaml>"
Path checks:
- If
REPO_ROOTis empty, stop and ask for repository root. - If
SKILL_DIRdoes not exist, stop and report path mismatch. - If
TARGET_FILEdoes not exist, stop and ask for the correct file.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

k8s-yaml-validator is a skill published in the GitHub repository akin-ozer/cc-devops-skills (307 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 29 tokens to every session and 7,747 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
