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 | $0.00032 | $0.01525 |
| Opus 5 | $0.00016 | $0.00763 |
| Sonnet 5 | $0.00006 | $0.00305 |
| Haiku 4.5 | $0.00003 | $0.00153 |
Grade C, and why
k8s-helm scanned grade C with 2 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Helm Chart Management
Comprehensive Helm v3 operations using kubectl-mcp-server's 16 Helm tools.
When to Apply
Use this skill when:
- User mentions: "helm", "chart", "release", "values", "repository"
- Operations: installing charts, upgrading releases, rollbacks
- Keywords: "package", "template", "lint", "repo add"
Priority Rules
| Priority | Rule | Impact | Tools |
|---|---|---|---|
| 1 | Template before install (dry run) | CRITICAL | template_helm_chart |
| 2 | Check existing releases first | CRITICAL | list_helm_releases |
| 3 | Lint charts before packaging | HIGH | lint_helm_chart |
| 4 | Note revision before upgrade | HIGH | get_helm_history |
| 5 | Verify values after upgrade | MEDIUM | get_helm_values |
| 6 | Update repos before search | LOW | update_helm_repos |
Quick Reference
| Task | Tool | Example |
|---|---|---|
| Install chart | install_helm_chart |
install_helm_chart(name, chart, namespace) |
| Upgrade release | upgrade_helm_release |
upgrade_helm_release(name, chart, namespace, values) |
| Rollback | rollback_helm_release |
rollback_helm_release(name, namespace, revision) |
| List releases | list_helm_releases |
list_helm_releases(namespace) |
| Get values | get_helm_values |
get_helm_values(name, namespace) |
| Template (dry run) | template_helm_chart |
template_helm_chart(name, chart, namespace) |
Install Chart
install_helm_chart(
name="my-release",
chart="bitnami/nginx",
namespace="web",
values={"replicaCount": 3, "service.type": "LoadBalancer"}
)
Upgrade Release
upgrade_helm_release(
name="my-release",
chart="bitnami/nginx",
namespace="web",
values={"replicaCount": 5}
)
Rollback Release
rollback_helm_release(
name="my-release",
namespace="web",
revision=1
)
Uninstall Release
uninstall_helm_chart(name="my-release", namespace="web")
Release Management
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-helm is a skill published in the GitHub repository rohitg00/kubectl-mcp-server (956 stars, last pushed 5mo ago), licensed MIT. It adds 32 tokens to every session and 1,525 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
