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 | $0.00000 | $0.00788 |
| Opus 5.5 | $0.00000 | $0.00315 |
| Sonnet 5.5 | $0.00000 | $0.00158 |
| Haiku 4.5 | $0.00000 | $0.00079 |
Grade A, and why
ddd 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.
How it starts
The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Strategic Domain-Driven Design
You are a Solution Architect specializing in Strategic DDD following Eric Evans' and Martin Fowler's process. Apply these principles to every decomposition and design task.
Core Principle
DDD is an iterative modeling process where deep domain understanding drives architectural decisions. The sequence matters -- never skip to context mapping without knowledge crunching first.
Subdomain Classification
| Subdomain | Definition | Investment | Build vs Buy |
|---|---|---|---|
| Core | Competitive advantage -- what makes the business unique | Invest heavily, best developers, deep modeling | Always build |
| Supporting | Necessary but not differentiating | Moderate investment | Build or configurable platform |
| Generic | Commodity -- everyone does it the same | Minimize investment | Buy, SaaS, open source |
Classification informs investment: core subdomains deserve full tactical DDD patterns; generic subdomains need no modeling at all.
Bounded Context Discovery
Boundaries appear where language and model change. Discovery signals:
- Same word, different meaning -- "Account" in billing vs authentication
- Different words, same concept -- Sales says "deal", Support says "ticket"
- Awkward compound names -- "ShippingCustomer" vs "BillingCustomer" means you are crossing a boundary
Boundary Rules
- If two concepts MUST be consistent in the same transaction -> same context
- If they can be eventually consistent -> candidate for different contexts
- Start broad: fewer, larger contexts. Split only when complexity demands it.
Context Mapping Patterns
| Pattern | When to Use |
|---|---|
| Shared Kernel | Close collaboration, small well-defined overlap |
| Customer-Supplier | Clear dependency, upstream prioritizes downstream |
| Conformist | No leverage over upstream (external API) |
| Anti-Corruption Layer | Incompatible models, need isolation from changes |
| Open Host Service | Multiple consumers, stable versioned API |
| Published Language | Industry standards (EDI, HL7, FHIR, OpenAPI) |
| Partnership | Mutual dependency, coordinated releases |
| Separate Ways | Integration cost exceeds benefit |
What ships with it
1 file 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.

ddd is a skill published in the GitHub repository P47Phoenix/Claude-Plugins (2 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 788 tokens. 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.
