secret-shield
Keeps secrets out of the transcript and out of the repo: redacts API keys, tokens, private keys and password URLs from tool results before Claude reads them, and refuses a Write, Edit or Bash command that embeds one.
What it does
- Draws a band above the prompt, toasts
- Adds /secrets
- Watches Bash calls and can refuse them
- Hooks session.append, session.start, turn.start
Good points
- No network calls
- Starts no processes
- Small: 210 lines
- Written in TypeScript
Code to start from
Two kinds: a starter modscode writes from the design above, and the lines of the mod's own code that draw it.
Starter (register.tsx)
import type { Register } from 'claude-code'
// Drawn like secret-shield by slopshopper (band, toast), as modscode read it from the mod's code:
// https://modscode.com/gallery/ryx2-secret-shield/
// Written by modscode from that reading, not copied from the mod: use it as you like.
// Each value below stands for one the mod works out at run time; put in your own.
export const register: Register = on => {
// the band above the prompt; what else goes there is drawn under it
on('ui.render', { component: 'AbovePrompt' }, async ($, e, next) => {
const { Box, Text, Button } = $.ui.resolve(e)
const redacted = '…'
const refused = '…'
const kind = '…'
const tool = '…'
return (
<Box flexDirection="column">
<Box flexDirection="row" columnGap={2} paddingX={1}>
<Text color="green" bold>
⛨ secret-shield
</Text>
<Text>
{redacted}
{" redacted"}
</Text>
<Text color="yellow">
{refused}
{" refused"}
</Text>
<Text dimColor>
{"latest: "}
{kind}
{" in a "}
{tool}
{" "}
result
</Text>
<Button label="Hide" hotkey="h" plain dimColor />
</Box>
{await next(e)}
</Box>
)
})
on('session.start', async ($, e, next) => {
const tool = '…'
const shortPath = '…'
const kind = '…'
await $.ui.toast(`Refused a ${tool} to ${shortPath}: it contains a ${kind}`)
await $.ui.toast(`Refused a Bash command that embeds a ${kind}`)
return next(e)
})
}

What its code calls
tool calls
The design, read from code
Drawn from the mod's source at the commit read, not from a run: a list is drawn three times, a condition takes its first branch that draws in the desktop app, and a value only the run time knows is shown as a made-up sample (dotted underline) or left out. Colours and type are this site's.
What its code shows
Read from the source at commit 7e163bd54648 on 2026-10-06. The first group decides whether a mod is listed; the rest is for you to weigh. A later commit is not read until the next crawl.
| Decides the listing: code you can check | |
|---|---|
| Entry read | Every module hooks/hooks.json names was read.mods/secret-shield/hooks/register.tsx |
| Parses | Every file parses as TypeScript or JavaScript.1 files parsed |
| All its code is in the mod | Every import is a file of the mod or the engine's own module; no packages, no require.all its code is in the mod |
| Readable | No minified lines, no eval or new Function, no import of a computed path, no encoded blobs.no minified code, no eval, no encoded blobs |
| Calls in the open | Network and programs are reached as $.http.fetch and $.process.run in place, never passed around.every call outside goes through $ in the open |
| For you to weigh before installing | |
| Where it draws | The terminal, the desktop app, both, or nothing (hooks only: a guard or a prompt rewriter), as its code says. Shown, never a reason to leave a mod out.draws in the terminal and the desktop app, the same in both |
| Install line | Whether its repository's own .claude-plugin/marketplace.json lists it, so it installs from that marketplace with the lines on its page.listed in its repository's .claude-plugin/marketplace.json: installs from there |
| Programs on Windows | Whether every program it starts through $.process exists on Windows (tail, date, open, osascript, /usr/… do not).runs no program a Windows PC lacks |
| Network | Whether every fetch names its https host in the code.no network |
| Programs | Whether every program it starts is named in the code and is not a shell, an interpreter or a network tool.starts no programs |
| Reads and sends | Whether it both reads files or environment variables and reaches the network.reaches no network |
| Keys in the source | Whether the source holds what looks like an API key or a private key.no keys in the source |
| Licence | An open licence (MIT, Apache-2.0, BSD, ISC, Unlicense, 0BSD, CC0) with its text lets modscode show its code; otherwise the code is linked.MIT |
This is a reading of the code text, not a security review: it does not run the mod, and it cannot see what a program the mod starts does. The check before installing is yours. How mods are chosen
Install it
Check it yourself before you install it. Mods run unsandboxed, with your permissions, and modscode does not vouch for what this code does. Read the code below (or run claude plugin validate . in its folder), weigh what it reaches, and install the commit you read.
Its repository is its marketplace. Add that marketplace (in the terminal with these commands, or in the desktop app's plugin settings) and install the mod from it:
/plugin marketplace add ryx2/slopshopper/plugin install secret-shield@slopshopperThis installs the marketplace's latest commit, which may not be the one read here (7e163bd54648). Compare them before you install.
Ask Claude about it
With the modscode connector added, Claude can read this design, what its code reaches and its code, and build on them. Ask it like this:
