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 | $0.00123 | $0.06878 |
| Opus 5 | $0.00062 | $0.03439 |
| Sonnet 5 | $0.00025 | $0.01376 |
| Haiku 4.5 | $0.00012 | $0.00688 |
Grade A, and why
ddd-architecture-awesome 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 today.
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.

DDD Architecture Awesome
The entry point to the DDD Skills ecosystem. This skill provides everything needed to understand DDD, decide if it's right for your project, and chart your learning path — all in one place.
When to Use (and When NOT to)
| ✅ Use When | ❌ Skip When |
|---|---|
| Complex business domain with many rules | Simple CRUD, few business rules |
| Long-lived system (years of maintenance) | Prototype, MVP, throwaway code |
| Team of 5+ developers | Solo developer or small team (1-2) |
| Multiple entry points (API, CLI, events) | Single entry point, simple API |
| Need to swap infrastructure (DB, broker) | Fixed infrastructure, unlikely to change |
| High test coverage required | Quick scripts, internal tools |
| Chinese enterprise Spring Boot + MyBatis stack | Already using established architecture that works |
Start simple. Evolve complexity only when needed. Most systems don't need full CQRS or Event Sourcing.

- Questions about DDD architecture types and their differences
- New to DDD and seeking guidance on where to start
1. DDD Definition
Domain-Driven Design is a development methodology that brings complex business rules into domain models: first define business boundaries (Strategic Design), then encode rules into models (Tactical Design).
Key insight: DDD is not about technology — it's about aligning your code with how the business thinks.
2. DDD Applicability Decision Tree
Evaluate along these dimensions and provide a "Suitable / Cautious / Not Recommended" conclusion:

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.

ddd-architecture-awesome is a skill published in the GitHub repository full-stack-skills/ddd-skills (5 stars, last pushed yesterday), licensed Apache-2.0. It adds 123 tokens to every session and 6,878 once invoked, about $0.0006 per session on Opus 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.
