Boycott Filter

Manage a personal boycott list conversationally. Users complain about brands, the agent adds them to a local list with their reason, and a Chrome extension warns them on any page from those brands — displaying their own words back to them.

Overview

This skill is the conversational layer of a 3-part system:

  1. This skill (Claude Code) — understands user intent, calls the local API
  2. Local sync server (scripts/server.js, port 7847) — stores the list, serves it to the extension
  3. Chrome extension (extension/) — scans pages, shows the warning banner

The user's value: they complain ONCE, they're reminded FOREVER — in their own voice, with their own reason. No more accidental clicks on brands they'd decided to stop supporting.

Prerequisites

  • Node.js 18+ installed
  • Chrome (or any Manifest V3 browser) with the bundled extension loaded manually (see README)
  • The local sync server must be running on port 7847

Check with:

curl -s http://127.0.0.1:7847/health

If not running, ask the user to run setup once in a terminal (the skill itself only has curl permission, by design — see README for security rationale):

bash ${CLAUDE_PLUGIN_ROOT}/scripts/setup.sh

Tell the user: "The boycott server isn't running. Open a terminal and run: bash ${CLAUDE_PLUGIN_ROOT}/scripts/setup.sh — that starts the local server and shows you how to load the Chrome extension. Then ask me again."

Instructions

When the user wants to ADD a brand

Detect phrases like:

  • "I'm done with X"
  • "Never buying from X again"
  • "Boycott X"
  • "Add X to my boycott list"
  • "Sick of X"

Extract:

  • Brand name (the thing they want to avoid)
  • Reason (their own words — critical, this is what will be shown back to them)
  • Aliases (optional — if you know subsidiaries, offer them: Nestlé → Nespresso, KitKat, Purina, etc.)

Then call:

curl -s -X POST http://127.0.0.1:7847/add \
  -H 'Content-Type: application/json' \
  -d '{"name":"BRAND","reason":"USER_REASON","aliases":["alias1","alias2"]}'

Keep the reason in the user's voice — don't paraphrase into corporate language. If they said "cheap garbage everywhere", store "cheap garbage everywhere" — not "low quality products with aggressive advertising".

If the user didn't give a reason, ask: "Got it. Any specific reason you want to remember why you decided to boycott?"

When the user wants to REMOVE a brand

Detect phrases like:

  • "Remove X from my boycott list"
  • "Unban X"
  • "Actually I'm fine with X now"

Call:

curl -s -X DELETE http://127.0.0.1:7847/remove \
  -H 'Content-Type: application/json' \
  -d '{"name":"BRAND"}'

When the user wants to SEE their list

curl -s http://127.0.0.1:7847/list

Display the brands and reasons nicely:

  • "You're currently boycotting N brands:"
  • - Temu: "Cheap garbage everywhere"
  • - Shein: "Fast fashion, not supporting"
  • - Nestlé (+ Nespresso, KitKat): "Water extraction in drought zones"

When the user asks about the extension

Explain that the Chrome extension needs to be loaded manually once:

  1. Open chrome://extensions
  2. Enable Developer mode
  3. Click "Load unpacked"
  4. Select: ${CLAUDE_PLUGIN_ROOT}/extension/

After that, it auto-syncs every 30 seconds from the local server.

Output

  • Confirmation messages for add/remove actions — include the exact reason captured
  • List displays grouped by company with reasons visible
  • Server status if asked

For add, confirm like:

"Added Temu to your boycott list. Reason: cheap garbage, ads everywhere. You'll see a red banner next time you land on temu.com or any page mentioning Temu."

API reference (the local server)

Method Endpoint Body Returns
GET /list — {"companies":[...], "updated_at":"..."}
POST /add {"name","reason","aliases":[]} {"ok":true, "list":{...}}
DELETE /remove {"name"} {"ok":true, "list":{...}}
GET /health — {"status":"ok", "companies":N}

Error Handling

  • Server not running (connection refused on port 7847): run the setup script. Don't silently fail — tell the user.
  • Brand already on list: server returns 409, tell the user gracefully ("Already on your list, reason: ...").
  • Brand not found on removal: server returns 404, tell the user it wasn't on the list.
  • Invalid JSON: server returns 400. Should not happen if the skill constructs the body correctly.

Examples

Example 1: Add with reason (most common)

User: "Ugh, another Shein ad. Never buying from them, fast fashion is killing everything."

Agent action:

curl -s -X POST http://127.0.0.1:7847/add \
  -H 'Content-Type: application/json' \
  -d '{"name":"Shein","reason":"fast fashion is killing everything","aliases":["shein.com","SHEIN"]}'

Response: "Added Shein. Next time you land on a page mentioning them, you'll see your reason: 'fast fashion is killing everything'."

Example 2: Parent + subsidiaries

User: "Boycott Nestlé, their water extraction practices in drought zones are criminal."

Agent action:

curl -s -X POST http://127.0.0.1:7847/add \
  -H 'Content-Type: application/json' \
  -d '{"name":"Nestlé","reason":"water extraction practices in drought zones are criminal","aliases":["Nestle","Nespresso","KitKat","Purina","Perrier","San Pellegrino"]}'

Response: "Added Nestlé with their main subsidiaries (Nespresso, KitKat, Purina, Perrier, San Pellegrino). The extension will match any of these. Want me to add more? Nestlé owns ~2,000 brands."

Example 3: List view

User: "What's on my boycott list?"

Agent action:

curl -s http://127.0.0.1:7847/list

Response formatting:

You're currently boycotting 3 brands:

  • Temu — "Cheap garbage, ads everywhere"
  • Shein — "Fast fashion is killing everything"
  • Nestlé (+ Nespresso, KitKat, Purina, Perrier) — "Water extraction practices in drought zones are criminal"

Example 4: Remove

User: "Actually remove Temu, I need something urgent from there."

Agent action:

curl -s -X DELETE http://127.0.0.1:7847/remove \
  -H 'Content-Type: application/json' \
  -d '{"name":"Temu"}'

Response: "Removed Temu from your list. You won't get the warning anymore. (No judgment — but you can always add it back later.)"
