-# queue
+# mosaic-queue
 
+Valkey/Redis-backed task queue with:
+
+- Atomic task lifecycle operations (`claim`, `release`, `heartbeat`, `complete`, `fail`)
+- CLI commands for queue management
+- MCP server tools for agent integrations
+
+## Requirements
+
+- Node.js `>=20`
+- pnpm `10.x`
+- Valkey/Redis URL in one of:
+  - `VALKEY_URL`
+  - `REDIS_URL`
+
+No default Redis URL is hardcoded. Startup fails loudly when neither env var exists.
+
+## Install
+
+```bash
+pnpm install
+pnpm build
+```
+
+## CLI Usage
+
+The package ships a `mosaic` binary.
+
+```bash
+mosaic queue create <project> <mission> <taskId> --title "..." [--priority high] [--lane coding]
+mosaic queue list [--project X] [--mission Y] [--status pending]
+mosaic queue show <taskId>
+mosaic queue claim <taskId> --agent <agentId> --ttl 3600
+mosaic queue release <taskId> [--agent <agentId>]
+mosaic queue complete <taskId> [--agent <agentId>] [--summary "..."]
+```
+
+Example:
+
+```bash
+export VALKEY_URL="redis://localhost:6379"
+mosaic queue create queue phase1 MQ-001 --title "Implement core queue"
+mosaic queue claim MQ-001 --agent codex --ttl 3600
+```
+
+## MCP Server
+
+The package also ships a `mosaic-queue-mcp` binary exposing:
+
+- `queue_list`
+- `queue_get`
+- `queue_claim`
+- `queue_heartbeat`
+- `queue_release`
+- `queue_complete`
+- `queue_fail`
+- `queue_status`
+
+Run over stdio:
+
+```bash
+export VALKEY_URL="redis://localhost:6379"
+mosaic-queue-mcp
+```
+
+## Development
+
+```bash
+pnpm lint
+pnpm test
+pnpm build
+```
+
+## Publish Prep
+
+`packages/queue/package.json` includes:
+
+- `bin` entries for `mosaic` and `mosaic-queue-mcp`
+- `exports` + `types` for ESM package consumption
+- `prepublishOnly` quality gate (`lint`, `test`, `build`)
+- `publishConfig.access = public`
