Tabularis is an open-source desktop application for connecting to and working with databases through SQL, including PostgreSQL, MySQL/MariaDB, SQLite, DuckDB, ClickHouse, Redis and Firestore. It is used for database exploration, querying, SQL notebooks and visual query-plan analysis, and includes an MCP server that lets Claude, Cursor and Devin access schemas and run queries.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00110 | $0.01624 |
| Opus 5.5 | $0.00044 | $0.00650 |
| Sonnet 5.5 | $0.00022 | $0.00325 |
| Haiku 4.5 | $0.00011 | $0.00162 |
Grade A, and why
tabularis-run-macos scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Run and drive Tabularis on macOS
Drives the real app the way the e2e suite does (e2e/, tauri-wd + WebDriverIO), but interactively: one session stays open and you send it small snippets, look at screenshots, and check files or databases between steps. No spec files.
macOS only. It relies on screencapture, osascript, CoreGraphics (swiftc) and the WKWebView WebDriver server. On Linux/Windows use the e2e setup in CI instead.
Scripts live in .claude/skills/tabularis-run-macos/scripts/. Below, SK is that directory and RUN_DIR is ${TMPDIR}/tabularis-run unless you set it (use the session scratchpad when you have one).
Prerequisites
tauri-wd:cargo install tauri-webdriver-automation --version 0.1.3 --locked- Xcode command line tools (
swiftc,screencapture) - The terminal needs Screen Recording permission for window captures, and Accessibility for real keystrokes via
osascript. - For databases other than SQLite, start them first (Docker/OrbStack). SQLite needs nothing.
1. Check out and launch
gh pr checkout <N> # or stay on the branch you changed
# optional: test the result of the merge, not the stale PR base
git merge --no-edit origin/main # local only, never push it
bash $SK/scripts/up.sh # build + tauri-wd + session (~1-2 min incremental)
up.sh backs up config.json and connections.dev.json (debug builds use the real config dir), builds with pnpm tauri build --debug --no-bundle -- --features e2e-testing, starts tauri-wd on :4444 and opens a session. Rebuild after every branch switch: the frontend is embedded in the binary. SKIP_BUILD=1 reuses the last build.
2. Act, look, verify
Write a snippet and run it from e2e/ (webdriverio resolves from there). The snippet is the body of an async function; return prints:
cat > $RUN_DIR/a.js <<'EOF'
await clickText('Add Connection'); await browser.pause(1200);
return await dump();
EOF
(cd e2e && node .drv-act.mjs $RUN_DIR/sid $RUN_DIR/a.js)
bash $SK/scripts/shot.sh $RUN_DIR/s1.png # then Read the png
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

tabularis-run-macos is a skill published in the GitHub repository TabularisDB/tabularis (5,265 stars, last pushed yesterday), licensed Apache-2.0. It adds 110 tokens to every session and 1,624 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-18.
