Claude Cowork

Install the LUU substrate as a bundled plugin in Claude Cowork (the agentic feature in Claude Desktop, available on paid Claude plans). About 3 minutes from get-key to first tool call.

What you'll get

Cowork will have access to 27 strategic-judgment tools (claims, sources, alternatives, info gaps, probability calibration, NATO source credibility, ICD 203 memo critique, scenario analysis, fact-check, and more) plus the judgment-augment Skill — Claude auto-applies the right substrate primitive bundle based on the workflow's shape (summarization, enrichment, monitoring, decision, generation, routing, evaluation).

"Use judgment-augment on this morning briefing — it's a summarization workflow."

…calls luu_augment with the right primitive bundle and returns the augmented artifacts + audit report.

Prerequisites

  • Claude Desktop with Cowork access (any paid Claude plan: Pro, Team, Enterprise)
  • An LUU API key — generate a free one (no card)

Path A — Personal install

For individual users on Pro / Team plans.

  1. Get the plugin packet. Clone the LUU repo:
    git clone https://github.com/cberzins1973/luu-attestation-anchors.git
cd luu-attestation-anchors/packages/cowork-plugins/luu-judgment-augment
  2. Open Claude Desktop → switch to the Cowork tab (left sidebar)
  3. Sidebar → Customize → Upload local plugin
  4. Select the luu-judgment-augment/ folder
  5. Paste your nb_* API key into the luu_api_key user-config field
  6. Click Install

Path B — Enterprise (MDM)

For organizations rolling out Cowork to a fleet of users via Jamf / Intune / Group Policy. Push this managedMcpServers JSON:

{
  "managedMcpServers": [
    {
      "name": "luu",
      "url": "https://api.leadershipunderuncertainty.org/api/mcp",
      "transport": "http",
      "headers": {
        "Authorization": "Bearer YOUR_TENANT_API_KEY"
      },
      "toolPolicy": {
        "luu_augment": "allow",
        "luu_brief": "allow",
        "luu_forecast": "allow",
        "luu_note_review": "allow",
        "luu_execute": "ask",
        "luu_subscribe": "ask"
      }
    }
  ]
}

Or drop the plugin folder into the org-plugins path:

  • macOS: /Library/Application Support/Claude/org-plugins/luu-judgment-augment/
  • Windows: C:\ProgramData\Claude\org-plugins\luu-judgment-augment\

Verify

In a fresh Cowork session:

"List the LUU MCP tools you have available."

Should include luu_augment, luu_brief, luu_forecast, etc. Then test the Skill:

"Use judgment-augment on this text: 'Reuters reports Tencent reduced its OpenAI API spending by 60% over the last quarter.' Treat it as a summarization workflow."

Cost

Free tier covers 25 calls/day, 500/month, 8 free-tier tools. Above that, augmentation calls are 3-22 credits ($0.03-$0.22) depending on shape. See pricing.

Caveats (Cowork-specific)

Per Anthropic's Cowork docs, the plugin upload UX is pre-GA. Bearer-token auth via plugin .mcp.json is supported but some users have reported intermittent auth issues. If you hit "Authorization with the MCP server failed":

  1. Verify the API key is set in user config
  2. Re-paste the key
  3. Workaround: install the same MCP in Claude Desktop's regular MCP tab (non-Cowork) where the auth flow is hardened — see Claude Desktop tutorial
