What is arch-suggest?

A command that examines an existing project and suggests prioritised architecture improvements. Software architecture is the way a project’s major parts are organised and connected.

Review architecture violations, classify their severity, identify affected files, propose solutions with examples, and find refactoring opportunities.

It turns detected architecture problems into concrete fixes, making it easier to decide what to refactor and where to start. It can use an earlier architecture-detection report when one exists.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00016	$0.00867
Opus 5	$0.00008	$0.00434
Sonnet 5	$0.00003	$0.00173
Haiku 4.5	$0.00002	$0.00087

Security

Grade A, and why

arch-suggest 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 9d 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.

This is a copy

/arch-suggest {repo|path}

Analiza un proyecto y genera sugerencias priorizadas de mejora arquitectónica.

Prerequisitos

Ejecutar /arch-detect primero (o se ejecutará automáticamente)
Acceso al repositorio

2. Cargar perfil de usuario

Leer .claude/profiles/active-user.md → obtener active_slug
Si hay perfil activo, cargar (grupo Architecture & Debt del context-map):
- profiles/users/{slug}/identity.md
- profiles/users/{slug}/projects.md
- profiles/users/{slug}/preferences.md
Adaptar profundidad del análisis según preferences.detail_level
Si no hay perfil → continuar con comportamiento por defecto

3. Parámetros

{repo|path} — Ruta local o nombre del repositorio

4. Flujo de Ejecución

1. Cargar detección previa

Si existe output/architecture/{proyecto}-detection.md, leerlo. Si no existe, ejecutar /arch-detect primero.

2. Analizar violaciones

Para cada violación del reporte de detección:

Clasificar severidad: CRITICAL (rompe el patrón) vs WARNING (desvío menor)
Identificar ficheros afectados
Proponer solución concreta con ejemplo

3. Identificar oportunidades de refactoring

Buscar:

God classes/modules: ficheros >300 líneas con múltiples responsabilidades
Dependencias inversas: módulos de bajo nivel usados por alto nivel
Código duplicado: patrones repetidos que deberían ser abstracciones
Missing abstractions: implementaciones directas sin interfaces/traits
Tight coupling: clases que instancian dependencias (new) en lugar de recibirlas

4. Priorizar por impacto × esfuerzo

Matriz de priorización:

	Esfuerzo Bajo	Esfuerzo Alto
Impacto Alto	🟢 Quick Win	🟡 Proyecto
Impacto Bajo	🔵 Nice to have	⚪ Postpone

5. Generar Reporte
