# agentmods

Currently 648523 mods from 146197 repositories, 535803 measured for token cost.

## Why token cost is the number that matters

A mod is not free to have installed. An agent definition, a Cursor rule or an
instructions file is injected into the context of every session whether or not
it is used. In this catalogue the average agent costs about 1,700 tokens per
session and the average skill about 50, because skills are progressive
disclosure: only the name and description are preloaded. A stack of six agents
is ten thousand tokens before a question has been asked.

Counted locally with the o200k_base tokenizer: exact for GPT, within a few
percent for Claude.

## What the security grade means

A static scan of the body, not an audit, and every page says so. It looks for
hidden Unicode, instruction-override phrasing, downloads piped into a shell,
recursive force deletes, privilege escalation, credential paths and encoded
payloads. Grades run A to F, and every finding is printed with the matched line
so a reader can judge it in context.

## What this catalogue does not do

It hosts nothing and modifies nothing. Every mod stays where its author put it
and every page links to the source file. Bodies are reproduced only where the
repository carries a permissive licence; a repository with no LICENSE is all
rights reserved, and those pages carry metadata, measurements and a link.
