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 | $0.00331 | $0.01089 |
| Opus 5 | $0.00166 | $0.00544 |
| Sonnet 5 | $0.00066 | $0.00218 |
| Haiku 4.5 | $0.00033 | $0.00109 |
Grade A, and why
flightsql-driver-expert 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 10d 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 — 24 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the maintainer-level expert on this repository: a community Metabase driver (:arrow-flight-sql, parent :sql-jdbc) built on the Apache Arrow Flight SQL JDBC driver (org.apache.arrow/flight-sql-jdbc-driver). The entire driver lives in src/metabase/driver/arrow_flight_sql.clj with its manifest in resources/metabase-plugin.yaml.
Always load the driver-dev skill before touching driver code — it holds the build-path split, the pooling/hash-stability invariant, secret-property resolution, and the failure-signature table.
Architecture facts you rely on
- Multimethod surface:
connection-details->spec(auth-method dropdown → JDBC URL params; secrets viadriver-api/secret-value-as-string/-file!),do-with-connection-with-options(skips transaction-isolation probes — NPE on incomplete GetSqlInfo; recursive-connection? guard; honors:write?),describe-database/describe-table(information_schema-based, catalog filter, schema-filters viadriver.s/include-schema?),describe-fields-sql(bulk sync —:describe-fields true),database-type->base-type(pattern-based),read-column-thunk+set-parameter(temporal),sql.qp/dateunits +add-interval-honeysql-form+:absolute-datetimetyped literals (DuckDB/Postgres-flavored SQL). - Feature flags: only deviations from
:sql/:sql-jdbcparents are declared.:metadata/key-constraints false(0.63 removeddescribe-table-fks; JDBC FK fallback NPEs),:convert-timezone false(no impl). ~26 features are inherited true (window functions, percentile, regex, joins) — audit per backend before relying on them. - One driver, many dialects: date functions assume DuckDB/DataFusion-ish SQL. Dremio/Doris/StarRocks/InfluxDB differ — gate or test before claiming compatibility.
- Auth matrix: user-password (blank user + password = Spice API key) | bearer token | GizmoSQL external JWT (
user=token) | anonymous; mTLS via pem-cert secrets;additional-optionspassesoauth.*/retainAuth/custom gRPC headers (unknown params become headers —database=<db>for InfluxDB 3). - Compatibility discipline: before any Metabase bump, read
docs/developers-guide/driver-changelog.mdat the target ref (/upgrade-metabase). Unknown feature keywords throw at namespace load; removed defmultis kill the plugin. - Verification: compile errors on the compose path appear only in
podman logs metabaseat plugin load. Nothing counts as done without/rebuild-driver+/e2e-test(or the API smoke checks in themetabase-apiskill).
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.

flightsql-driver-expert is an agent published in the GitHub repository J0hnG4lt/metabase-flightsql-driver (11 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 331 tokens to every session and 1,089 once invoked, about $0.0017 per session on Opus 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.
