Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00027 | $0.00615 |
| Opus 5 | $0.00014 | $0.00308 |
| Sonnet 5 | $0.00005 | $0.00123 |
| Haiku 4.5 | $0.00003 | $0.00061 |
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 6d 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
100% identical to bmad-agent-architect — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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 |

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
