A small local VS Code extension that makes opencode aware of the editor.
Features
Right-click menu (editor/context): add the selection, selection + code, current line, or the whole file to the opencode prompt.
Live selection tracking (onDidChangeTextEditorSelection): the current @file#Lx-y is shown in the status bar and written to ~/.config/opencode/selection.json.
Keybindings: Ctrl+Alt+K adds the selection, Ctrl+Alt+Shift+K adds the selection with its code.
Bridge for the AI: the selection opencode custom tool reads selection.json, so the agent can look at your live selection on demand.

Settings
opencodeContext.autoShare (default false): forward selection changes to the prompt automatically.
opencodeContext.autoShareMode: reference or referenceWithText.
opencodeContext.debounceMs: debounce for auto-share.
opencodeContext.port: override the opencode server port (0 = auto-detect).
opencodeContext.writeBridge: write the live selection for the selection tool.
Notes
The opencode server port is discovered from the opencode terminal's _EXTENSION_OPENCODE_PORT
environment variable, so this works together with the official sst-dev.opencode extension.
