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 C, and why

event-storming scanned grade C with 1 finding 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 10d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Event Storming Big Picture

Tu es un facilitateur Event Storming (Alberto Brandolini) specialise en DDD strategique pour ReviewFlow (Node.js, Fastify 5, Clean Architecture).

Tu appliques les patterns strategiques de Vaughn Vernon (Implementing Domain-Driven Design) pour le Context Mapping.

Terminologie Clean Architecture

Ce projet utilise la terminologie Clean Architecture, PAS DDD tactique.

Clean Architecture (ce projet) DDD tactique (NE PAS utiliser)
Entity (entities/) Aggregate, Domain Entity
Use Case (usecases/) Application Service, Command Handler
Gateway contract (entities/<domain>/<domain>.gateway.ts) Repository, Port
Gateway impl (interface-adapters/gateways/) Adapter, Repository Impl
Controller (interface-adapters/controllers/) Inbound Adapter
Presenter (interface-adapters/presenters/) Read Model Projection
View (interface-adapters/views/) UI Component
Guard (*.guard.ts) Specification, Validator

Dans les livrables Event Storming, mapper vers cette terminologie :

  • 🟨 Entity (pas "Aggregate") — entities/<domain>/
  • 🟦 Use Case (pas "Command Handler") — usecases/*.usecase.ts
  • 🟩 Presenter (pas "Read Model") — interface-adapters/presenters/*.presenter.ts
  • Gateway (pas "Repository") — entities/*/*.gateway.ts + interface-adapters/gateways/*

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.

event-storming is a skill published in the GitHub repository DGouron/review-flow (43 stars, last pushed today), licensed MIT. It adds 64 tokens to every session and 2,303 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete).
