feat(agent): add Cursor Agent CLI runtime support#1057
Conversation
Add cursor-agent as a new agent backend, following the same pattern as existing providers. The implementation spawns cursor-agent CLI with stream-json output, parses JSONL events into the unified Message type, and supports session resume, usage tracking, and auto-approval (--yolo). Changes: - server/pkg/agent/cursor.go: cursorBackend implementation - server/pkg/agent/cursor_test.go: unit tests for args, parsing, errors - server/pkg/agent/agent.go: register "cursor" in New() factory - server/internal/daemon/config.go: probe cursor-agent in PATH - server/internal/daemon/execenv/context.go: cursor skill discovery path - server/internal/daemon/execenv/runtime_config.go: AGENTS.md injection - packages/views/.../provider-logo.tsx: cursor logo in UI Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

1. Fix token usage double-counting: usage is now taken exclusively from "result" events (session totals). Per-message usage in "assistant" events is intentionally ignored. "step_finish" usage is only used as fallback when no "result" usage is available. 2. Remove dead code: isCursorUnknownSessionError() and its regex were defined but never called. Removed along with corresponding test. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
