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

shieldcn-badges 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 9d 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.

Great badge rows

Add a polished shieldcn badge row to my README for [owner/repo]. Include npm
version/downloads if this package is published as [package], GitHub stars,
license, CI status, and last commit. Center the row, make badges clickable, and
use a subtle shadcn style that works on GitHub light and dark themes.
Replace the existing Shields.io badges in this README with shieldcn equivalents.
Keep the same links where possible, remove stale or duplicate badges, and keep
the final row to 3-6 high-signal badges.
Migrate the existing Shields.io badges in this README to shieldcn, but undo any
split-style/two-tone badges. Use single-surface shieldcn badges instead: remove
split=true, labelColor, and other split-label styling unless a split badge is
explicitly needed for readability.
Create a compact shieldcn badge group for [owner/repo] with stars, license,
contributors, and last commit. Use one grouped image when that is cleaner than
separate badges.
Add release-quality README badges for a TypeScript library named [package]. I
want npm version, monthly downloads, license, types, GitHub stars, CI, and a
small branded static badge if it improves the visual hierarchy.

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.
