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 | $0.00093 | $0.01770 |
| Opus 5.5 | $0.00037 | $0.00708 |
| Sonnet 5.5 | $0.00019 | $0.00354 |
| Haiku 4.5 | $0.00009 | $0.00177 |
Grade A, and why
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 2mo 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 — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Software Architecture
Overview
Software architecture is the set of significant decisions about the organization of a software system -- the selection of structural elements, their interfaces, composition, and the guiding principles that constrain design and evolution over time. Choosing the right architecture style is one of the highest-leverage decisions a team makes; it shapes every subsequent technical and organizational choice.
This skill covers how to reason about architecture styles, evaluate architecture characteristics (quality attributes), and make informed tradeoffs. For deep dives into specific styles, see the sub-skills below.

The Monolith-to-Microservices Spectrum
Architecture is not a binary choice between monolith and microservices. It is a spectrum of modularity:

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 is a skill published in the GitHub repository Tyler-R-Kendrick/agent-skills (13 stars, last pushed 5mo ago), licensed MIT. It adds 93 tokens to every session and 1,770 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-08-31.
