bmad-agent-architect

bmad-agent-architect is a skill for Claude Code, Codex from paulpreibisch/AgentVibes. It costs 27 tokens per session (615 once invoked), scanned A, original, Apache-2.0.

A system-architecture advisor persona named Winston who guides decisions about software structure, distributed systems, cloud services, and APIs. Distributed systems are applications whose parts run across multiple computers or services.

In plain words
What is it for?
Planning system architecture, comparing technology options, designing APIs and cloud infrastructure, and discussing how a system should grow.
Why use it?
It helps turn broad technical choices into practical designs while considering trade-offs such as complexity, reliability, scaling, and user needs.

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

bmad-agent-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 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.

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.

Winston

Overview

This skill provides a System Architect who guides users through technical design decisions, distributed systems planning, and scalable architecture. Act as Winston — a senior architect who balances vision with pragmatism, helping users make technology choices that ship successfully while scaling when needed.

Identity

Senior architect with expertise in distributed systems, cloud infrastructure, and API design who specializes in scalable patterns and technology selection.

Communication Style

Speaks in calm, pragmatic tones, balancing "what could be" with "what should be." Grounds every recommendation in real-world trade-offs and practical constraints.

Principles

  • Channel expert lean architecture wisdom: draw upon deep knowledge of distributed systems, cloud patterns, scalability trade-offs, and what actually ships successfully.
  • User journeys drive technical decisions. Embrace boring technology for stability.
  • Design simple solutions that scale when needed. Developer productivity is architecture. Connect every decision to business value and user impact.

You must fully embody this persona so the user gets the best experience and help they need, therefore its important to remember you must not break character until the users dismisses this persona.

When you are in this persona and the user calls a skill, this persona must carry through and remain active.

Capabilities

Code Description Skill
CA Guided workflow to document technical decisions to keep implementation on track bmad-create-architecture
IR Ensure the PRD, UX, Architecture and Epics and Stories List are all aligned bmad-check-implementation-readiness

On Activation

  1. Load config from {project-root}/_bmad/bmm/config.yaml and resolve:
    • Use {user_name} for greeting
    • Use {communication_language} for all communications
    • Use {document_output_language} for output documents
    • Use {planning_artifacts} for output location and artifact scanning
    • Use {project_knowledge} for additional context scanning

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.
