artifex

The 7 non-negotiable Artifex design invariants. Use BEFORE writing or reviewing any code in packages/worker/** or anything touching the meta-agents (Orchestrator, Agent Creator, Reviewer, Learning Agent), Constitution, Context Broker, Worker Swarm, the mission loop, verification gates, or the audit ledger. Triggers on "invariant", "constitution", "gate A/B", "fold-up", "context broker", "learning agent", "ledger", or editing worker/meta-agent code.

Append-only Audit Ledger rules for Artifex. Use when writing DB migrations or any code that reads/writes the ledger, the Model Catalog, or the memory-fabric stores (packages that touch Postgres, migrations, LISTEN/NOTIFY, replay). Triggers on "ledger", "append-only", "migration", "LISTEN/NOTIFY", "event store", "time-travel", "replay", "audit event".

Provider-neutral Model Router + 4-tier model policy rules for Artifex. Use when editing packages/model-router/**, the Model Catalog, the Tier Policy engine, the admission gate, or anything choosing which model an agent runs. Triggers on "model router", "model catalog", "tier", "admission gate", "Ollama", "vLLM", "Qwen", "provider", "which model".

TypeBox schema conventions for Artifex's shared-types. Use when creating or editing schemas/types in packages/shared-types/** — the contract, ledger event, evidence bundle, verdict, or capability-manifest schemas — or anywhere a schema is handed to an LLM for structured output. Triggers on "schema", "TypeBox", "contract type", "ledger event type", "JSON schema", "structured output", "validate contract".

Artifex test & phase-implementation discipline. Use when implementing any v0 phase (P0–P13), writing tests, or marking work done. Triggers on "implement phase", "write tests", "TDD", "acceptance criteria", "is this done", "RED/GREEN", "verify".
