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 | $0.00020 | $0.00317 |
| Opus 5 | $0.00010 | $0.00159 |
| Sonnet 5 | $0.00004 | $0.00063 |
| Haiku 4.5 | $0.00002 | $0.00032 |
Grade A, and why
ddd-strategic-design 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 8d 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
DDD Strategic Design
Use this skill when
- Defining core, supporting, and generic subdomains.
- Splitting a monolith or service landscape by domain boundaries.
- Aligning teams and ownership with bounded contexts.
- Building a shared ubiquitous language with domain experts.
Do not use this skill when
- The domain model is stable and already well bounded.
- You need tactical code patterns only.
- The task is purely infrastructure or UI oriented.
Instructions
- Extract domain capabilities and classify subdomains.
- Define bounded contexts around consistency and ownership.
- Establish a ubiquitous language glossary and anti-terms.
- Capture context boundaries in ADRs before implementation.
If detailed templates are needed, open references/strategic-design-template.md.
Required artifacts
- Subdomain classification table
- Bounded context catalog
- Glossary with canonical terms
- Boundary decisions with rationale
Examples
Use @ddd-strategic-design to map our commerce domain into bounded contexts,
classify subdomains, and propose team ownership.
Limitations
- This skill does not produce executable code.
- It cannot infer business truth without stakeholder input.
- It should be followed by tactical design before implementation.
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-strategic-design is a skill published in the GitHub repository beel-collab/presets.dev (2 stars, last pushed 4mo ago), licensed MIT. It adds 20 tokens to every session and 317 once invoked, about $0.0001 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.
