@makaio/extension-opencode

Import session logs from the OpenCode AI coding tool.

Uses the logImport extension contribution to read OpenCode's JSON session files and normalise them into Makaio session events. This is the reference implementation for the logImport contribution seam — no storage, tools, UI, or triggers are needed.

Schema verified against OpenCode v1.1.x logs (2026-01-22).

Browser surface

descriptor.json currently declares entrypoints.browser: true, so src/browser.ts exists for descriptor/source alignment. The browser entrypoint default-exports a valid no-op ExtensionBrowserFactory and returns an empty contribution object. No runtime browser UI is provided by this extension.

Features

• Log importer — parses OpenCode session JSON files into Makaio messages
• Auto-detection — watches **/storage/session/*/*.json for new/updated log files
• Incremental import — file watcher triggers partial re-import on change

Log import seam

| Field | Value | |-------|-------| | adapterName | plugin:opencode | | displayName | OpenCode | | logFilePattern | **/storage/session/*/*.json | | LogImporterClass | OpenCodeLogImporter |

The canonical runtime adapter name for imported session events is plugin:opencode, defined by the executable logImport.adapterName in src/index.ts. The descriptor's contributions.logImporters entry is discovery metadata; it does not register a second runtime adapter.

Config

No configuration schema — the extension activates as-is.
