swag

swag is a skill for Claude Code from jmagar/swag-mcp. It costs 118 tokens per session (1,110 once invoked), scanned A, original, MIT.

A tool for creating and managing SWAG reverse-proxy settings. SWAG is a server setup that uses nginx to route internet requests to services on another computer.

In plain words
What is it for?
Create, view, edit, list, and remove proxy configurations, including backend addresses and optional authentication settings.
Why use it?
It avoids manually editing nginx configuration files when exposing services through a subdomain or subfolder. It can also show whether proxy settings are enabled.

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

swag 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 1mo 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.

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.
