tls-termination

tls-termination is a skill for Claude Code from sawrus/agent-guides. It costs 30 tokens per session (1,373 once invoked), scanned A, original, MIT.

HTTPS certificate and encryption setup for Kubernetes services, using cert-manager with Let's Encrypt or an internal Vault certificate authority. It also covers wildcard certificates and mTLS, which requires services to authenticate to each other.

In plain words
What is it for?
Use it to configure HTTPS, issue or rotate certificates, create wildcard certificates, and set up mutual TLS between services.
Why use it?
It removes the need to handle certificate issuance and renewal rules manually when securing services and their connections.

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

tls-termination scanned grade A with 1 finding 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 8d 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.

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.
