Supabase test harness patterns including local Supabase setup, test user creation via Auth Admin API, RLS testing, migration testing (db_reset), seed sequences, rate limiting, and environment detection. Use when setting up Supabase testing infrastructure, creating test users, troubleshooting Supabase test failures, or implementing RLS validation. Triggers on: supabase test setup, test user creation, supabase local testing, RLS testing, migration testing, supabase test harness, auth test helpers.
Supabase operational knowledge for migrations, RLS optimization, MCP tool benchmarks, and ADR-003 compliance. Use when validating database migrations, optimizing Row-Level Security policies, checking MCP tool performance, or ensuring Supabase operational standards. Triggers on: migration validation, RLS patterns, Supabase benchmarks, ADR-003, database state tracking, schema governance.
LLM-native structured communication format. Teaches OCTAVE syntax rules, canonical forms, and warning prevention for zero-error .oct.md authoring.
Advanced semantic vocabulary, holographic contracts, and structural patterns for OCTAVE. REQUIRES octave-literacy. Extends literacy with mythology, archetype annotation, v6 contracts, and anti-pattern rules.
Workflow for transforming prose into semantic OCTAVE structures. Covers tier selection, transformation phases, loss accounting, and decision rules. REQUIRES octave-literacy.
Strategic oversight mode for the Holistic Orchestrator. Episodic State Machine pattern with ho-liaison advisory (via pal_clink), run_debate escalation, and oa-router delegation. REPLACES holistic-orchestration when loaded.
