contract-consistency

contract-consistency is a skill for OpenCode from cruzs85/opencode-multiagente-local-37-iterations. It costs 0 tokens per session (572 once invoked), scanned A, original, MIT.

A checklist for keeping the interfaces between dependent project files consistent.

In plain words
What is it for?
Use it before writing a file that imports or calls another file, such as a component using a service or a service implementing an interface.
Why use it?
It prevents components, services, models, and interfaces from disagreeing about names, types, method signatures, or parameters.

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 A, and why

contract-consistency scanned grade A with 0 findings 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 12d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

SKILL: contract-consistency

Propósito

Antes de implementar un archivo que dependa de otro, verificar que los contratos (tipos, métodos, propiedades) sean consistentes entre ambos.

¿Cuándo usarla?

Siempre que code-writer vaya a implementar:

  • Un componente que llama a un servicio
  • Un servicio que implementa una interfaz
  • Un servicio que usa tipos definidos en un modelo
  • Cualquier archivo que importe de otro archivo del proyecto

Reglas obligatorias

Regla 1: Leer antes de escribir

Antes de escribir un archivo A que depende de un archivo B:

  1. LEER el archivo B completo
  2. Identificar TODOS los nombres de métodos, propiedades, tipos e interfaces que A va a usar
  3. Usar EXACTAMENTE esos nombres — sin cambios, sin "alias", sin "variantes"

Regla 2: Consistencia de tipos literales

Si el modelo define: type: 'cactus' | 'pterodactyl' El servicio DEBE usar EXACTAMENTE: 'cactus' o 'pterodactyl' NO usar: 'bird', 'cactus2', 'CACTUS'

Regla 3: Firmas de métodos

Si el servicio define: jump(): void El componente DEBE llamar: service.jump() NO llamar: service.doJump(), service.jumpDino(), service.saltar()

Regla 4: Parámetros

Si el servicio define: updateGameLoop(deltaTime: number) La llamada DEBE incluir: service.updateGameLoop(deltaTime) NO: service.updateGameLoop() (sin el parámetro requerido)

Regla 5: Retorno de métodos

Si un servicio devuelve un tipo, el componente debe tratar el retorno según ese tipo:

  • Si devuelve ReadonlySignal<GameData>, leer con service.gameData()
  • Si devuelve DinoState, acceder a sus propiedades directamente

Cómo usar esta skill

  1. Cargar esta skill ANTES de escribir cualquier archivo
  2. Identificar el archivo del que se depende
  3. Leer ese archivo con la herramienta read o cat
  4. Escribir el nuevo archivo usando EXACTAMENTE los mismos nombres y tipos

Anti-patrones

❌ Escribir un componente que llama a gameService.jump() sin verificar que jump() existe en GameService ❌ Definir un tipo 'pterodactyl' en el modelo y usar 'bird' en el servicio ❌ Llamar a un método sin pasar los parámetros requeridos ❌ Asumir que un método existe sin leer primero el archivo que lo define

contract-consistency is a skill published in the GitHub repository cruzs85/opencode-multiagente-local-37-iterations (5 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 572 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
