01

What it is

A mod that judges mods.

modwall hooks the moment another mod loads, reads what Claude Code's own scanner found in its code, and turns it into reach labels such as prompts, tool-gate, network and processes, with a risk level.

02

Why we built it

Mods run with your permissions.

A mod can read every prompt, approve tool calls and reach the network, and nothing on screen tells you which ones do. Within a week of launch there were well over a hundred, most barely reviewed.

03

How to use it

Audit, then allowlist.

  • Install it and run /modwall scan to see every mod's footprint.
  • Start in audit mode for a week.
  • Move to allowlist and approve the mods you rely on with /modwall allow.
04

Why it is a smart idea

An allowlist, not a blocklist.

Anything modwall does not recognise counts as high risk, so a new API in next week's release is treated as dangerous until someone looks at it. It even rates itself high, and says so.

05

What it changes

Mods treated like dependencies.

Teams can adopt mods without guessing: a clear footprint for each one, and a policy that decides what loads.
