copilot-instructions k8s.instructions.md

copilot-instructions k8s.instructions.md is an instructions file for GitHub Copilot from ThiagoGuislotti/copilot-instructions. It costs 2,123 tokens per session, scanned A, original, MIT.

A set of Kubernetes instructions for running containerized applications with security, resource, health-check, configuration, and network rules. Kubernetes is a system for deploying and managing containers across servers.

In plain words
What is it for?
Use it when writing or reviewing Kubernetes settings for pod security, permissions, secrets, networking, scaling, availability, and health checks.
Why use it?
It helps teams avoid insecure containers, missing resource limits, weak access controls, and unreliable deployments.

Token cost

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.

Security

Grade A, and why

copilot-instructions k8s.instructions.md 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.

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.
