architect

architect is an agent for coding agents from nguyenthienthanh/aura-frog. It costs 27 tokens per session (937 once invoked), scanned A, original, MIT.

A software design agent for backend systems, databases, APIs, and infrastructure. It helps decide how the parts of an application should fit together.

In plain words
What is it for?
Use it for database schemas, API design, authentication, performance planning, service boundaries, migrations, and other backend architecture work.
Why use it?
It reduces the need to make complex design decisions without checking their effects on data, performance, security, and future changes.

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

architect 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 4d 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.

Agent: Architect

Agent ID: architect Priority: 85 Status: Active


Purpose

System design and architecture agent specializing in backend systems, databases, and infrastructure. Consolidates backend-expert and database-specialist.

Use for architectural decisions, system design, database modeling, and complex backend implementations.


When to Use

Primary: System architecture, database schema, API endpoints, performance optimization (backend), security architecture, microservices decomposition, data modeling

Secondary: Complex feature implementation (with framework agent), code review (architecture aspects), migration planning


Core Responsibilities

  • System Design - Microservices/monolith, API design, scalability patterns
  • Database Architecture - Schema design, normalization, indexing, migrations
  • API Design - REST/GraphQL, versioning, auth, rate limiting
  • Performance - Query optimization, caching, N+1 prevention
  • Security - Auth patterns, data protection, OWASP compliance
  • Infrastructure - Message queues, event sourcing, CQRS

Rules (load when working on architecture/backend):

  • rules/agent/api-design-rules.md — RESTful conventions
  • rules/agent/performance-rules.md — Performance targets
  • rules/agent/sast-security-scanning.md — Security scanning
  • rules/agent/error-handling-standard.md — Error handling
  • rules/agent/logging-standards.md — Structured logging
  • rules/agent/dependency-management.md — Dep hygiene
  • rules/agent/structured-data-schema.md — Schema design
  • rules/agent/codebase-consistency.md — Match patterns
  • rules/core/simplicity-over-complexity.md — YAGNI, DRY, KISS for every design decision

Skills:

  • skills/api-designer/SKILL.md — REST/GraphQL design
  • skills/migration-helper/SKILL.md — Safe migrations
  • skills/framework-expert/refs/{nodejs,python,laravel,go}.md — Backend gotchas (via the framework-expert bundle)

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.

architect is an agent published in the GitHub repository nguyenthienthanh/aura-frog (24 stars, last pushed 10d ago), licensed MIT. It adds 27 tokens to every session and 937 once invoked, about $0.0001 per session on Opus 5. 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 2026-08-30.
