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 | $0.00918 | $0.00918 |
| Opus 5.5 | $0.00367 | $0.00367 |
| Sonnet 5.5 | $0.00184 | $0.00184 |
| Haiku 4.5 | $0.00092 | $0.00092 |
Grade A, and why
tabularis AGENTS.md 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 24d 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.

GitNexus — Code Intelligence
This project is indexed by GitNexus as tabularis (10537 symbols, 25156 relationships, 300 execution flows). Use the GitNexus MCP tools to understand code, assess impact, and navigate safely.
Index stale? Run
node .gitnexus/run.cjs analyzefrom the project root — it auto-selects an available runner. No.gitnexus/run.cjsyet?npx gitnexus analyze(npm 11 crash →npm i -g gitnexus; #1939).
Always Do
- MUST run impact analysis before editing any symbol. Before modifying a function, class, or method, run
impact({target: "symbolName", direction: "upstream"})and report the blast radius (direct callers, affected processes, risk level) to the user. - MUST run
detect_changes()before committing to verify your changes only affect expected symbols and execution flows. For regression review, compare against the default branch:detect_changes({scope: "compare", base_ref: "main"}). - MUST warn the user if impact analysis returns HIGH or CRITICAL risk before proceeding with edits.
- When exploring unfamiliar code, use
query({search_query: "concept"})to find execution flows instead of grepping. It returns process-grouped results ranked by relevance. - When you need full context on a specific symbol — callers, callees, which execution flows it participates in — use
context({name: "symbolName"}). - For security review,
explain({target: "fileOrSymbol"})lists taint findings (source→sink flows; needsanalyze --pdg).
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 AGENTS.md is an instructions file published in the GitHub repository TabularisDB/tabularis (5,223 stars, last pushed yesterday), licensed Apache-2.0. It adds 918 tokens to every session, about $0.0037 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 2026-08-30.
