@closurenetwork/ide

Closure Agent Pack for your IDE. Published on npmjs.org under the closurenetwork org — never clone this repo.

This package is a thin installer. AGENTS.md, Cursor rules, and Closure-way skills are fetched from Closure Platform Knowledge (GET /api/public/ide/pack) — not hardcoded here.

The authoring contract

Your IDE agent doesn't just get tools — it gets a runtime that holds up its half of the loop:

1. The runtime teaches. platform_docs_search grounds paradigm answers in the docs, the book The Last Application, and the whitepaper. platform_taxonomy serves the live vocabulary — every schema, component kind, workflow node type, and composition rule, straight from the registries that will execute them.
2. The runtime checks before you write. platform_validate dry-runs any DataObject, Experience graph, or workflow graph and returns the exact violations.
3. The runtime gates what ships. Creativity is welcome; the ship bar is not negotiable. platform_experience_verify runs the same server-side craft gates a governed build enforces (design system, taxonomy-pure components, i18n, discoverability, accessibility). Gate keys are server-owned — clients can't mark their own work as passing.
4. The runtime delegates. Governed builds (platform_build_start) hand creative planning nodes to your agent's context on waiting_ide — original IA, copy, and brand voice, inside the gates.
5. The runtime ships. Dev is the live graph; Test and Prod serve pinned versions. platform_experiences_health shows pin state, platform_experiences_promote snapshots Dev and pins Test/Prod, and platform_release_snapshot / platform_release_promote cut org-wide releases — with the same role, policy, and quality-gate checks the console enforces.
6. The runtime learns. Anonymous friction telemetry (failed calls, unanswered docs searches, gate failures — never prompts, code, or identity) auto-opens platform Issues with recommended fixes. Opt out with CLOSURE_TELEMETRY=0.

Install

Run this in a normal terminal (Cursor’s integrated terminal or iTerm/Terminal.app) — not via the Agent’s Shell tool:

npx @closurenetwork/ide@latest init

Then reload MCP → Connect → call platform_status → platform_knowledge_skills_pull.

Why not from the Agent?

Cursor sandboxes agent shell commands. init needs outbound network (registry.npmjs.org + Closure) and writes .cursor/mcp.json. Cursor hard-protects .cursor/*.json from the agent (by design — so agents can’t silently rewrite MCP/auth config). A real terminal has neither restriction. After init, the agent can still refresh rails via npx @closurenetwork/ide sync (rules/skills live under writable .cursor/ subdirs) and work through Connect.

On-prem / local Studio

STUDIO_URL=http://localhost:3021 npx @closurenetwork/ide init
# or
CLOSURE_IDE_PACK_URL=http://localhost:3021/api/public/ide/pack npx @closurenetwork/ide init

Commands

| Command | Purpose | |---------|---------| | init | Fetch pack, write rails, register MCP | | sync | Re-fetch pack (Knowledge updates) | | status | Local + remote pack health | | doctor / update | Aliases of status / sync |

Auth — prefer Connect

{
  "mcpServers": {
    "closure": {
      "url": "https://mcp.closureapps.com",
      "type": "http"
    }
  }
}

Fallback — stdio + API key

The stdio shim exposes the core authoring subset (status, scaffold, craft, collect, build, workflows, agent task/submit). The full authoring contract above — grounding, taxonomy, validation, verification, promotion, feedback — is served by the hosted HTTP MCP; prefer Connect.

npx @closurenetwork/ide init --stdio

{
  "mcpServers": {
    "closure": {
      "command": "npx",
      "args": ["-y", "@closurenetwork/ide", "mcp-stdio"],
      "env": {
        "STUDIO_URL": "https://closureapps.com/console",
        "STUDIO_API_KEY": "csk_…"
      }
    }
  }
}
