consort

v0.3.97

Consort: a Spec-First Branched-Database TDD agent framework for building transactional applications on Lakebase (Databricks' serverless Postgres/OLTP database, not the Delta Lakehouse). A deterministic orchestrator drives role agents through a spec-first design lane and a test-driven build lane whose every cycle runs against a live copy-on-write branch of a real Postgres database, with human-in-the-loop gates that fail closed. For application backends on Postgres, not ETL or analytics. Run /consort:start to launch the workflow.

Included Skills3

architectural-design-principlesskills/architectural-design-principles/SKILL.md

System-level engineering canon, the architecture counterpart to software-design-principles. Layered architecture + dependency direction, ports and adapters (repository / ORM-as-adapter), the twelve-factor app for cloud-native development, evolutionary architecture with fitness functions, and evolutionary database design (schema that evolves by migration on paired branches). Imported by workflow skills (consort, lakebase-scm-workflows). Use when: shaping a system boundary, deciding what is a backing service, mapping config to the environment, or authoring the fitness functions that keep the architecture honest as it evolves.

software-design-principlesskills/software-design-principles/SKILL.md

Foundational engineering canon – SOLID, DRY, clean code, layered architecture, cross-cutting concerns, NFRs. Imported by workflow skills (consort, lakebase-scm-workflows). Use when designing a module, reviewing a PR, planning a refactor, mapping cross-cutting concerns to layers, or arguing about API shape.

ui-ux-design-principlesskills/ui-ux-design-principles/SKILL.md

Experience-level engineering canon, the UI/UX counterpart to software-design-principles (code-level) and architectural-design-principles (system-level). Usability heuristics, visual hierarchy, accessibility, interaction and feedback, information architecture, design systems and tokens, and testable UI. Imported by the consort UX Designer (authoring design-guide.{md,json} + ia.md and the adherence gate) and by the Driver building UI. Use when: shaping a design guide or information architecture, reviewing a user-facing surface, choosing a UI framework, or making the UI testable.
