DB Browser

Install DB Browser for SQLite via Homebrew if it isn't already installed, then open a given .sqlite file in it. Macos only — uses brew --cask + open -a.

Usage: /db-browser <path-to.sqlite>

ARGUMENTS: $ARGUMENTS

Steps

1. Resolve the path argument. If empty, default to $(bash scripts/sutando-config.sh workspace)/data/conversation.sqlite (the M0 helper — reads sutando.config.local.json, defaulting to <repo>/workspace/data/conversation.sqlite; $SUTANDO_WORKSPACE no longer honored as of v0.8 / #1440). Bail with an error if the file doesn't exist.
2. Check whether DB Browser for SQLite is installed: mdfind "kMDItemKind == 'Application'" 2>/dev/null | grep -qi 'DB Browser for SQLite' (or [ -d /Applications/DB\ Browser\ for\ SQLite.app ]). If installed, skip step 3.
3. Install via Homebrew: brew install --cask db-browser-for-sqlite. Requires brew. If brew is missing, stop and ask the user to install brew first.
4. If DB Browser is already running on a DIFFERENT db file (its cached snapshot of THAT db won't auto-refresh when you switch files), quit it first: osascript -e 'tell application "DB Browser for SQLite" to quit'; sleep 2. Skip if not running.
5. Open the file: open -a "DB Browser for SQLite" "<resolved-path>". Sleep ~2s so the window is up before reporting back.
6. Confirm: print the resolved path + verify DB Browser has the file open via lsof -c "DB Browser" 2>/dev/null | grep "<resolved-path>".

Notes

• DB Browser caches the schema + first page of data at open time. If the on-disk db file changes underneath (e.g. a migration drops tables, a writer adds rows), the open DB Browser window keeps showing the stale view until you re-open it. That's why step 4 quits first when re-opening — same-file re-open is also a valid refresh trigger.
• WAL flush: if the db is in WAL mode and recent writes haven't merged into the main file, the .sqlite-wal sidecar holds them. DB Browser reads both — no checkpoint needed. (Run sqlite3 <db> 'PRAGMA wal_checkpoint(TRUNCATE);' only if you want a single-file dump.)
• This skill does NOT screenshot, query, or modify the db. Just install + open. Anything else (screenshot for a PR, run a SQL via Execute SQL, export CSV) is the operator's job in the GUI.
