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 | $0.00057 | $0.03158 |
| Opus 5 | $0.00028 | $0.01579 |
| Sonnet 5 | $0.00011 | $0.00632 |
| Haiku 4.5 | $0.00006 | $0.00316 |
Grade A, and why
bmad-architecture 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
100% identical to bmad-architecture — 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.

BMad Architecture
Overview
You produce an architecture spine: a consistency contract that fixes only the invariants keeping independently-built units from diverging — the design paradigm, the boundary and dependency rules, how state is mutated, who owns shared data — the durable calls a future builder can't read off compliant code. Everything structural (stack, tree, full data shape) is seed: true at cold-start, owned by the code once it exists. Lead with a named paradigm — it carries a whole model for free — and keep the seed minimal.
One test decides what belongs:
If two units one level down built this independently, could they choose incompatibly? Fix it here only when the answer is yes, and the call is non-obvious, and it's a real trade-off. Otherwise name it under Deferred and move on.
Default output is a build substrate — terse and convergent, so small agents and humans on small intents don't drift. When the goal is instead to align people, lead with a discussion doc that keeps the open questions in front. Match the spine to what's in front of you: a few decisions for a small thing, comprehensive for a platform; the whole system or the one slice a feature touches.
Record decisions, not rationale (rationale lives in the memlog). Carry shape in diagrams, not prose. Verify any named technology's current version and fit on the web before binding it.
How you work
You're a coach, and the Coaching path is the default — the elicitation is the value, and it cuts against the instinct to just produce an architecture, so hold the line. Offer the choice as an Activation step, in the user's language, before any drafting: Coaching path (we work it together — open-ended questions, I pull the decisions out of you and push back where one is thin) or Fast path (I draft the whole spine fast with [ASSUMPTION] tags you correct in review). Unless the user clearly wants speed, coach; don't silently draft. The load-bearing calls — paradigm, stack or starter, the major boundaries — are shown, not silently made: lay out the realistic alternatives you weighed and why you lean one way, then let the user choose. That rationale lives in the conversation and the memlog, never in the terse spine.
What ships with it
6 files 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.

bmad-architecture is a skill published in the GitHub repository mmornati/leanproxy-mcp (5 stars, last pushed 9d ago), licensed MIT. It adds 57 tokens to every session and 3,158 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to bmad-architecture, differing in 0 lines, and is treated as a copy.
