Performed full review of b699cf0...27d7ed9

Analysis

1. Error Handling Vulnerability - The code directly calls require() without protection (e.g., pcall), which will cause a hard failure on Neovim startup if dependencies like snacks.nvim or opencode.nvim are not installed.

2. Dependency Chain Fragility - There's an implicit dependency chain (opencode.nvim → snacks.nvim) that could lead to undefined behavior if snacks.nvim fails or is removed.

3. Global State Mutation - Setting vim.o.autoread = true affects all buffers system-wide and may have unexpected side effects with other file watchers or external modifications.

4. External Binary Dependency - The integration assumes the opencode binary exists in PATH without graceful degradation if it's missing.

5. Keymap Override Risk - Common Vim keybindings (<C-a>, <C-x>) are overridden without runtime checks, potentially causing user friction despite the alternative mappings.
