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.

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 | $0.00043 | $0.02169 |
| Opus 5 | $0.00022 | $0.01085 |
| Sonnet 5 | $0.00009 | $0.00434 |
| Haiku 4.5 | $0.00004 | $0.00217 |
Grade A, and why
kustomize 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 455 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Kustomize
Customize Kubernetes resources declaratively without templating.
When to Use This Skill
Use this skill when:
- Managing Kubernetes configs across environments
- Patching existing manifests without modification
- Creating configuration variants from bases
- Customizing third-party manifests
- Preferring declarative over templating approach
Prerequisites
- kubectl 1.14+ (includes kustomize)
- Or standalone kustomize CLI
- Basic Kubernetes manifest knowledge

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.

kustomize is a skill published in the GitHub repository BagelHole/DevOps-Security-Agent-Skills (1,037 stars, last pushed 3mo ago), licensed MIT. It adds 43 tokens to every session and 2,169 once invoked, about $0.0002 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.
