Configuration

On first run, the app creates a config file at:

~/.config/schwi/config.json

The config uses a schema version for safe upgrades. Example:

{
  "schema_version": 1,
  "last_seen_app_version": "0.1.0"
}

Sessions

Each run creates a JSONL session file scoped to the current project. Sessions are stored under:

~/.config/schwi/sessions/<project_id>/<session_id>.jsonl

Use /session to view the active session ID, /sessions to list sessions for the current project, and /resume <session_id> to continue a past session.

Versioning

The displayed version is resolved from the installed package metadata. If the package metadata is unavailable, the version falls back to 0.0.0.

Lint

uv run ruff check src
