e2e-protocol

e2e-protocol is a skill for OpenCode from cruzs85/opencode-multiagente-local-37-iterations. It costs 22 tokens per session (886 once invoked), scanned A, original, MIT.

A testing procedure for Playwright, a tool that checks complete user flows in a browser, with rules for handling repeated failures.

In plain words
What is it for?
Use it to run browser-based end-to-end tests, classify failures, assign fixes, and decide when to stop retrying.
Why use it?
It prevents the same test failure from being sent repeatedly to different agents. Each failure gets one owner, one correction attempt, and escalation if the same fingerprint returns.

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

e2e-protocol 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 2mo 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.

OBJETIVO

Garantizar validaciones E2E determinísticas evitando ciclos entre:

  • @e2e-validator
  • @code-writer
  • @decomposer

REGLAS OBLIGATORIAS

1. Ownership único del fallo

Cada fallo detectado debe generar un único responsable:

  • [ui-renderizado] → @code-writer
  • [datos-incorrectos] → @code-writer
  • [lógica-de-negocio] → @decomposer

PROHIBIDO reenviar el mismo fallo a diferentes agentes.

2. Fingerprint del fallo

Antes de delegar una corrección, generar un fingerprint:

Formato:

E2E::::::

Ejemplo:

E2E::login.spec.ts::should login::locator timeout button submit

Si el fingerprint reaparece:

  • NO volver a delegar al mismo agente.
  • Escalar inmediatamente.

LÍMITES DE ITERACIÓN

Regla estricta

Máximo:

  • 1 corrección por @code-writer
  • 1 análisis por @decomposer

Secuencia permitida:

  1. Ejecutar Playwright
  2. Detectar fallo
  3. Delegar UNA vez
  4. Reejecutar Playwright
  5. Si falla el MISMO fingerprint:
    • TERMINAR
    • Escalar
    • NO reintentar

PROTOCOLO DE ESCALADO

Escalar a @decomposer SOLO si:

  • El fallo es [lógica-de-negocio]
  • O el mismo fingerprint reaparece tras corrección

Información obligatoria para escalado

Enviar SIEMPRE:

  • archivo spec
  • nombre del test
  • mensaje completo
  • stack trace
  • screenshot exacto
  • pasos reproducibles
  • fingerprint

PROHIBICIONES

@e2e-validator NO puede:

  • editar archivos
  • sugerir cambios vagos
  • reenviar errores sin fingerprint
  • ejecutar más de 2 corridas Playwright por tarea
  • delegar el mismo fingerprint dos veces

REGLA DE CIERRE

Si el mismo fingerprint persiste tras:

  • 1 corrección
  • 1 rerun

La tarea debe marcarse como:

ESTADO: BLOCKED CAUSA: Persistent E2E failure

y finalizar inmediatamente.

CRITERIO DE ÉXITO

Una validación E2E válida requiere:

  • mínimo 1 ejecución real de Playwright
  • máximo 2 ejecuciones
  • ausencia de fingerprints repetidos
  • evidencia de screenshot/log cuando exista fallo

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.
