Research direction

Start with docs/internal/2026-08-12-dbt-optimization-taxonomy-research.md and map its detection areas to the planned dbt-optimizer agent behind the Optimize workflow. Define the read-only scan, candidate selection, fix application, cost/impact reporting, and PR outputs, while preserving the stated warehouse-write, equivalence, and query-history safety gates. Done means the named agent covers the agreed scope without weakening those requirements.

Written by the indexing model from the issue text.

Description

Feature

Add a new native primary agent, dbt-optimizer, that scans an existing dbt project for concrete, fixable issues and proposes targeted fixes with cost and impact reporting. This is the agent behind the planned Optimize workflow.

Input: an existing dbt project (connected repository and environment).
Output: candidates (detected issues), fixes for user-selected candidates, impact reports (batch effect incl. estimated cost change), and PRs for applied fixes.

Detection scope (from the dbt-optimization taxonomy research, docs/internal/2026-08-12-dbt-optimization-taxonomy-research.md):

  • materialization & incremental processing (strategy-aware: merge / delete+insert / insert_overwrite / microbatch, precondition-gated)
  • warehouse physical design (clustering / partitioning / sort keys, query-history gated)
  • SQL anti-patterns, DAG economics (fan-out, duplicate scans, dead models), run-level orchestration (Slim CI, threads, full-refresh overuse), tests/docs/storage

Safety requirements: scan phase is read-only; warehouse writes denied non-overridably; SQL rewrites gated on decidable equivalence; cost claims only from attributed query-history evidence.

Named dbt-optimizer (not optimizer) because more optimizer agents are planned later.
