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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00122 | $0.00511 |
| Opus 5.5 | $0.00049 | $0.00204 |
| Sonnet 5.5 | $0.00024 | $0.00102 |
| Haiku 4.5 | $0.00012 | $0.00051 |
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 1mo 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.

What it actually says
.NET Architecture
Trigger On
- choosing architecture for a new or evolving .NET system
- reviewing layer boundaries, domain boundaries, or service decomposition
- deciding whether clean architecture, vertical slices, CQRS, or microservices are justified
Workflow
- Start from business capability boundaries and change frequency, not from a preferred diagram style.
- Use simple modular monolith patterns by default, and move to microservices only when team autonomy, scale, or deployment boundaries justify the added operational cost.
- Apply DDD and CQRS where business rules are genuinely complex; avoid forcing aggregates and command pipelines into CRUD-heavy code with no payoff.
- Keep dependencies flowing inward when using clean architecture, but avoid creating extra projects that add ceremony without ownership clarity.
- Make integration boundaries explicit: contracts, storage ownership, messaging, consistency model, and observability expectations.
- Use
aspirewhen local orchestration, service discovery, and developer observability are part of the architecture story.
Deliver
- an architecture direction that matches system complexity
- clear project and dependency boundaries
- migration notes or tradeoffs when changing an existing structure
Validate
- the proposed structure reduces rather than increases accidental complexity
- data ownership and integration paths are explicit
- the architecture is testable and operable, not just diagram-friendly
References
- references/patterns.md - detailed implementations of Clean Architecture, Vertical Slices, DDD, CQRS, Modular Monolith, and Microservices with C# 12+ examples

What ships with it
3 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.
- 1mo ago First seen · 40 lines · 122 tokens per session scan A 35b3860113c1
architecture is a skill published in the GitHub repository managedcode/dotnet-skills (496 stars, last pushed yesterday), licensed MIT. It adds 122 tokens to every session and 511 once invoked, about $0.0005 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 2026-09-03.
