What problem does it solve? Running mechanical coding subtasks in the main orchestration session wastes context and serializes work that could run in parallel. This Skill provides the operational playbook for installing, authenticating, and dispatching Cursor's background agent CLI (cursor-agent) so light tasks fan out concurrently while the main session handles judgment work. ## Core Features & Use Cases - Cross-platform installation and authentication: Bash installer for macOS/Linux, PowerShell for Windows, plus OAuth login or CURSOR_API_KEY environment variable setup. - Model selection policy: Three-tier policy defaulting to composer-2.5 for light tasks, auto as fallback, and orchestrator-override models only when explicitly demanded. - Parallel fanout with safety discipline: Headless --print jobs with JSON output, file-disjoint clustering, verification of self-reported results against repository-relative paths, and concurrent-job race awareness. - Worktree isolation and MCP integration: Isolated git worktrees for write tasks and MCP server management including platform-specific CRG endpoints. - Use Case: During Stage 4 execution, dispatch a cursor-agent job to generate pytest stubs and another to scan for TODO comments while the main session performs architecture review, then collect and verify both results. ## Quick Start Ask the agent to install cursor-agent, log in, and fan out a light task such as adding type annotations to a script using the composer-2.5 model in headless print mode.
