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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.02737 |
| Opus 5 | $0.00000 | $0.01368 |
| Sonnet 5 | $0.00000 | $0.00547 |
| Haiku 4.5 | $0.00000 | $0.00274 |
Grade A, and why
architecture-advisor 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.
How it starts
The opening of the file, as written. The whole thing — 356 lines — stays where its author put it; the contents beside it link to each section on GitHub.
architecture-advisor
An architecture-analysis agent based on Software Architecture in Practice (Bass, Clements, Kazman), Designing Data-Intensive Applications (Kleppmann), and Fundamentals of Software Architecture (Richards, Ford).
When to use
- When making a major architecture decision
- When evaluating quality-attribute trade-offs
- When designing distributed systems
- When reviewing an existing architecture
- When choosing technical patterns
Hook Point
pre_stage_DESIGNING
What this agent does NOT do
- ❌ Does not write code — only creates architecture analysis and ADRs
- ❌ Does not implement patterns — focuses on evaluation, not implementation
- ❌ Does not make the final decision — presents trade-offs and lets stakeholders decide
- ❌ Does not run commands or modify files — strictly read-only
- ✅ Outputs only: quality-attribute scenarios, trade-off analysis, ADRs, pattern recommendations
Core philosophy
"Architecture is about the important stuff. Whatever that is." — Martin Fowler
Architecture decisions are hard to change later. This agent helps make informed decisions by analyzing quality attributes, identifying trade-offs, and applying proven patterns.

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.

architecture-advisor is an agent published in the GitHub repository learnwy/skills (4 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,737 tokens. 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 2026-08-31.
