ade-bench-cross-db-tasks

ade-bench-cross-db-tasks is a skill for Claude Code, Codex from dbt-labs/ade-bench. It costs 40 tokens per session (1,985 once invoked), scanned A, original, Apache-2.0.

Guidance for creating or debugging ADE-Bench tasks that work with DuckDB and Snowflake, two database systems with different SQL behavior.

In plain words
What is it for?
Use it when writing migrations, task setup scripts, database-specific patches, or solution patches for cross-database benchmarks.
Why use it?
It prevents setup and solution patches from being applied in the wrong order or against the wrong database state.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

ade-bench-cross-db-tasks 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 12d 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.

ADE-Bench Cross-DB Task Authoring

Overview

Tasks in ade-bench can target DuckDB (default) or Snowflake. A task's files go through a deterministic four-stage lifecycle. Patches that ignore this order produce context mismatches or "reversed patch" prompts that block execution.

Container Lifecycle (in order)

1. MIGRATION   shared/migrations/<name>/migration.sh + migration.patch
               — Converts shared project files from DuckDB to Snowflake syntax
2. SETUP       tasks/<id>/setup.sh  +  tasks/<id>/setup/changes.patch
                                       tasks/<id>/setup/changes.snowflake.patch (optional)
               — Creates the puzzle state the agent must solve
3. AGENT       (agent works here)
4. SOLUTION    tasks/<id>/solution.sh  +  tasks/<id>/solutions/changes.patch
                                          tasks/<id>/solutions/changes.snowflake.patch (optional)

Critical: Migration runs before setup and solution. Any line migration touches is in its post-migration state when patches run.

Patch File Pattern

Always apply the base patch, then conditionally apply the snowflake delta. This applies to both setup.sh and solution.sh:

patch -p1 < /app/setup/changes.patch           # always (use /sage/solutions/ for solution.sh)

if [[ "$*" == *"--db-type=snowflake"* ]]; then
    patch -p1 < /app/setup/changes.snowflake.patch  # additive delta only
fi

Never use if/else to choose between two alternative patches. The base patch handles DuckDB; the snowflake patch stacks on top for Snowflake.

changes.snowflake.patch is a delta — it only contains changes that differ from the DuckDB result. It never replicates what migration already did.

Migration Guidelines

Migration's job: Convert DuckDB-specific syntax to Snowflake equivalents across all tasks sharing a project.

  • Schema names: schema: mainschema: public
  • Date functions: STRPTIME(...)TO_DATE(TO_TIMESTAMP(...))
  • Generator functions, STRFTIME, etc.

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.

ade-bench-cross-db-tasks is a skill published in the GitHub repository dbt-labs/ade-bench (123 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 40 tokens to every session and 1,985 once invoked, about $0.0002 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.
