Un-Default

io.github.NomadBuilderPublished by GitHub account NomadBuilderv0.5.6Updated Oct 24, 2026

Catch racist, sexist & ableist defaults in AI and human copy. Local rules, no account.

Overview

AI-generated overview

Reviews copy, docs, UI strings, and live pages for racist, sexist, and ableist defaults, explaining findings and suggesting clearer alternatives.

What you can do
Un-Default scans text for biased defaults, sexist assumptions, ableist metaphors, and documented dogwhistles, then explains what it noticed and offers clearer alternatives. Its MCP tools are un_default_scan, un_default_fix, and un_default_feedback. Matching runs on local open rules and does not require an AI model. It can also scan paths, changed files, and batches of URLs, and output JSON or SARIF.
When to use it
Use it after an assistant writes UI copy, documentation, or marketing text, or before publishing, to catch problematic defaults. It also fits into pull request checks and editor workflows where copy should be reviewed consistently.
Requirements
Runs locally as an npm package via npx (Node.js required). No account, API key, or environment variable is declared. The MCP server is started with the mcp subcommand. Network access is only needed for URL scanning or optional anonymous action pings.
Before you install
The fix tool can write changes to files, so preview with a dry run first. Findings are advisory and context-dependent, and ambiguous or quoted matches stay advisory. The GitHub Action sends anonymous action_run pings unless telemetry is disabled. Scanning URLs sends those pages to the local tool.

Installation

In SourceWeft

  1. Open Un-Default in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

Un-Default

One thoughtful-language check for every way you build.

Formerly Anti-Default. Same tool — the name shifted so it reads as undoing defaults, not opposing people. Old URLs under darkai.ca/anti-default redirect here. npx anti-default still works as an alias for npx -y anti-default.

Un-Default reviews copy, docs, UI strings, and live pages for racist defaults, sexist assumptions, ableist metaphors, and documented dogwhistles. It explains what it noticed and offers clearer alternatives.

No account. No AI required for matching. Open rules you can tune.

After Claude / Cursor writes UI copy

One command — skill + MCP + PR check. This is the habit that sticks:

bash
npx -y anti-default init

That also writes examples/un-default-demo.md and prints a sample scan so you see a finding immediately. Browser demo (shareable): /?demo=1.

Or install the Claude Code plugin from this repo’s marketplace:

bash
claude plugin marketplace add NomadBuilder/un-defaultclaude plugin install un-default@un-default

Paste-ready MCP JSON and Claude Project instructions:

https://darkai.ca/un-default/for-agents/

Directory checklist: docs/PUBLISH-DIRECTORIES.md

Paste MCP config (Cursor · Claude Desktop · Claude Code)

json
{  "mcpServers": {    "un-default": {      "command": "npx",      "args": ["-y", "anti-default", "mcp"]    }  }}
HostWhere it goes
Cursor.cursor/mcp.json (written by init) or Settings → MCP
Claude DesktopSettings → Developer → Edit Config → claude_desktop_config.json (merge, quit, relaunch)
Claude CodePlugin marketplace (above), or .mcp.json via init, or claude mcp add

Tools: un_default_scan · un_default_fix · un_default_feedback


Add it in under a minute

bash
npx -y anti-default .

That is the whole local setup. It prints findings and exits non-zero on clear hits. Ambiguous or quoted matches stay advisory.

To pin it in a team project:

bash
npm install --save-dev anti-default

Want the complete project setup?

bash
npx -y anti-default init

init adds an ignore file, changed-files GitHub workflow, Cursor + Claude skills, .cursor/mcp.json + .mcp.json, Claude/Cursor after-edit hooks, CLAUDE.md instructions, and inclusive-check / inclusive-fix scripts. Existing files are never overwritten. Hooks surface hard findings back to the agent after Edit/Write so Claude keeps checking even when nobody remembers.

AI-copy habit (definition of done)

bash
npx -y anti-default fix .          # safe 1:1 autofixes onlynpx -y anti-default .              # remaining findings

Agents should not mark UI/docs work done until hard findings are cleared or explicitly marked fine in context. Soft/coded hits stay advisory.

bash
# Preview autofixes without writingnpx -y anti-default fix . --dry-run
# Intentional language — suppress locally + share structured feedbacknpx -y anti-default feedback --kind fine_in_context \  --rule guys-generic --match "guys" --context "…snippet…" \  --note "Quoted lyric" --open-issue

MCP server

bash
npx -y anti-default mcp

See for-agents for host-specific paste steps.

Scan the way you work

bash
# Pathsnpx -y anti-default ./src ./docs README.md
# CI formatsnpx -y anti-default . --format json  -o report.jsonnpx -y anti-default . --format sarif -o results.sarif
# Batch URLs — no Review UInpx -y anti-default --urls https://example.com https://example.com/aboutnpx -y anti-default --urls-file urls.txt --format json
# Only files changed in this branchnpx -y anti-default . --changed-from origin/main
# Keep existing findings quiet; report only new onesnpx -y anti-default baseline .

Ignore what doesn’t matter

Commit a .undefaultignore so day-two noise doesn’t drown the team (example):

node_modules/vendor/*.min.jsrule:guys          # turn off one rule for this repo

GitHub Action

Keep racist, sexist & ableist defaults out of the PR loop. This scans only changed files, fails on clear new findings, and leaves a checklist comment:

yaml
# .github/workflows/un-default.ymlname: Un-Defaulton: [pull_request]permissions:  contents: read  pull-requests: write  security-events: write
jobs:  scan:    runs-on: ubuntu-latest    steps:      - uses: actions/checkout@v4        with:          fetch-depth: 0      - uses: NomadBuilder/un-default@v1        with:          changed-from: ${{ github.event.pull_request.base.sha }}          format: json          comment-on-pr: "true"          # telemetry: false   # opt out of anonymous action_run pings

Prefer SARIF for Code Scanning? Set format: sarif and output-file: un-default.sarif. Full inputs: action.yml.

Anonymous Action pings (no repo name or findings) feed public totals at darkai.ca/un-default/usage. Badge:

Agent skill

npx -y anti-default init installs .cursor/skills/un-default/SKILL.md — the definition-of-done workflow for AI-generated copy: fix → scan → ask or feedback → re-scan.

Use it as a library

The npm package has no runtime dependencies and exposes the same analyzer used by the CLI and web app:

ts
import { analyzeText, LANGUAGE_RULES } from "anti-default";
const result = analyzeText("Welcome, you guys.");console.log(result.findings);

Chrome extension

Same rules as the app — on the page you’re already looking at.

Add to Chrome →

Runs offline from a bundled rule list. No tracking. No AI calls.
Dev / unpacked: npm run extension:pack → Load unpacked → extension/ · details in extension/README.md

Web app — try, learn, tune

darkai.ca/un-default

  • Review — paste, upload, or scan a URL; export Markdown, CSV, or a checklist
  • Swap — turn one phrase into clearer alternatives
  • Dogwhistles — learn what a phrase can signal and when context matters
  • Rules — tune the open rule catalog for your project
bash
npm install && npm run dev   # localhost:3000

Why teams reach for it

  • Before publish — catch defaults in marketing, docs, and product copy
  • In the PR — Action + SARIF/JSON so machines and humans both get a signal
  • On the live page — extension for writers who never open a terminal
  • Without a lecture — suggestions are invitations; context always wins

Every suggestion cites the style guides and references behind it → /sources


Customize & self-host

  • Tune in the UI: /rules · edit code: src/lib/rules.ts
  • Practice corpus: npm run corpus
  • Static export: npm run build → out/
    Subpath (DarkAI): STATIC_EXPORT=true BASE_PATH=/un-default npm run build

Production lives at darkai.ca/un-default and is also vendored in DarkAI.
