Context (Rust + Flutter)

Context session manager for Codex, Kimi Code, OpenCode, and Qwen Code. Offers account switching and pacing on Codex as well.

Screenshot

• Flutter (UI)
• Rust (backend) via Rinf
• Codex recent sessions from ~/.codex/state_5.sqlite
• Kimi recent sessions from ~/.kimi-code/session_index.jsonl

Run (Linux dev)

flutter run -d linux

Build Context.appx (Windows)

From a Windows machine (PowerShell), in this project folder:

powershell -ExecutionPolicy Bypass -File .\scripts\bootstrap_windows_appx.ps1

Or double-click:

• Build_APPX.bat

• BUILD_WINDOWS_APPX_POWERSHELL.md

APPX tooling

The APPX kit is included under appx/scripts/, so this clone is self-contained for packaging scripts. The wrappers in scripts/ invoke only this local kit; no additional APPX kit checkout or environment override is needed.

The kit does not vendor Flutter, Rust, Visual Studio, certificates, generated APPX files, or caches. By default, the scripts keep Flutter and Rust-related dependencies in the external local %LOCALAPPDATA%\\AppxKit\\deps cache. APPX_DEPS_ROOT and APPX_DEPS_ROOT_LOCAL can override the dependency roots; see the Windows APPX build guide for the cache and prerequisite details.

Regenerate Dart bindings (Rinf)

Signals sent between Dart and Rust are implemented using signal attributes. If you modify Rust signal structs, regenerate bindings:

rinf gen

Refresh and save behavior

Codex accounts and recent sessions refresh in the background. Setting, editing, or removing a manual reset saves local metadata without waiting for the usage API. Refresh responses preserve newer reset edits. Without a manual override, each account uses its own API-reported reset.

Account usage reads run concurrently (up to three at a time), after serial credential preparation and snapshot writes. The refresh interval remains 30 seconds. UI updates rebuild only the affected sections; unchanged account and recent-session payloads are reused, and themes rebuild only when changed.

Account cards highlight on hover and keyboard focus. Pressing an inactive card shows a subtle edge pulse while switching, followed by a short confirmation on success. These effects preserve the usage chart and respect reduced-motion settings.

Session autosave waits 500 ms after an edit. Background refreshes do not replace unsaved edits, and edits made during a save remain pending for the next save. Saving the sessions markdown does not trigger an extra account refresh.

Regression checks (Windows)

With the build prerequisites installed and Dart bindings generated (rinf gen):

powershell -ExecutionPolicy Bypass -File .\scripts\test_refresh.ps1

This runs Rust tests, Dart formatting checks, Flutter analysis, and refresh/save UI tests using temporary fixtures, without live credentials or API requests. Coverage includes bounded usage-read concurrency, isolated request failures, and section rebuild isolation. Flutter checks use a temporary NTFS directory so the command also works from a WSL path. Logs, exact commands, and SHA256 evidence are written under .buildlog/refresh-validation/. Use -FlutterDir if your Flutter SDK is elsewhere, or -EvidenceDir to keep a separate validation report.
