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 | $0.00043 | $0.01984 |
| Opus 5 | $0.00022 | $0.00992 |
| Sonnet 5 | $0.00009 | $0.00397 |
| Haiku 4.5 | $0.00004 | $0.00198 |
Grade A, and why
software-design-ddd-domain-modeling 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 12d 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.

DDD Domain Modeling for Architecture
Overview
This skill is the architect-private domain modeling workflow for architecture design.
Use it when the real difficulty is not selecting middleware, but deciding:
- how the business should be split into domains and subdomains
- where bounded contexts should begin and end
- how contexts relate and where translation / anti-corruption is needed
- where aggregate and consistency boundaries should sit
- how those modeling decisions should appear in 概要设计 or 详细设计 rather than staying as abstract DDD vocabulary
Core principle: domain modeling is not a theory appendix; it is a design tool for reducing semantic and consistency ambiguity before implementation.
This skill is intentionally narrower than the architect general playbook. It does not try to own the whole architecture delivery chain. It specializes in the part of architecture work where domain boundaries and model structure dominate the design outcome.
When to Use
Use when:
- the architecture task is at 概要设计 or 详细设计 stage and domain boundaries are still unclear
- the user asks about 领域 / 子域 / 限界上下文 / 上下文映射 / 聚合 / 事件风暴
- the system has business complexity that cannot be explained well by component diagrams alone
- service boundaries or ownership boundaries depend on language/model boundaries
- multiple teams or subsystems disagree on concepts, state ownership, or consistency responsibility
Do not use when:
- the main problem is only delivery packaging or stage planning
- the task is only code-level refactor or implementation optimization
- the problem is mostly diagram set choice with no meaningful domain ambiguity
- the work is a tiny technical feature with no real business boundary question
Why This Skill Exists Separately
The architect general playbook answers:
- what stages the design should go through
- what artifacts should be produced
- where risk should be front-loaded
- how handoff happens
This skill answers a different question:
- how to shape the semantic and consistency structure of the system before those artifacts are finalized
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.

software-design-ddd-domain-modeling is a skill published in the GitHub repository xiaohei-info/oh-my-multica (26 stars, last pushed 5d ago), licensed MIT. It adds 43 tokens to every session and 1,984 once invoked, about $0.0002 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 2026-08-30.
