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 | $0.00000 | $0.02528 |
| Opus 5 | $0.00000 | $0.01264 |
| Sonnet 5 | $0.00000 | $0.00506 |
| Haiku 4.5 | $0.00000 | $0.00253 |
Grade A, and why
k8s-core 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 4d 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 — 550 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill: k8s-core
Comprehensive read-first Kubernetes reference using RootCause MCP tool names.
Use this skill when the task is to inspect, query, explain, and trace core resources.
Mission
Deliver high-signal cluster state with minimal noise.
Default flow:
- verify context and connectivity
- scope namespace and selectors
- list/get/describe resources
- correlate logs and events
- summarize facts and open questions
Core Resources Covered
- Pods
- Deployments
- Services
- ConfigMaps
- Secrets
- Namespaces
- Nodes
Core Tool Set

Priority Rules
| Priority | Rule | Reason |
|---|---|---|
| P0 | Run k8s.context then k8s.ping before data collection |
prevent wrong-cluster conclusions |
| P1 | Start broad with k8s.overview for unknown scope |
quick health baseline |
| P2 | Prefer k8s.list with selectors before k8s.get loops |
less API chatter, cleaner outputs |
| P3 | Use k8s.describe for state transitions and owner chains |
richer operational context |
| P4 | Use k8s.events_timeline for chronology, k8s.events for raw detail |
time ordering matters |

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-core is a skill published in the GitHub repository yindia/rootcause (42 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,528 tokens. 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.
