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 | $0.00032 | $0.01456 |
| Opus 5.5 | $0.00013 | $0.00582 |
| Sonnet 5.5 | $0.00006 | $0.00291 |
| Haiku 4.5 | $0.00003 | $0.00146 |
Grade A, and why
nw-ddd-tactical 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 4d 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 — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tactical DDD
Implementation patterns within a bounded context. Tactical DDD answers: "How do we structure the domain model?"
Aggregates
An aggregate is a consistency boundary -- a cluster of domain objects that must be transactionally consistent.
Vernon's Four Design Rules
-
Model true invariants in consistency boundaries: Only include elements that MUST be consistent within the same transaction. If two entities don't share an invariant, they belong in separate aggregates.
-
Design small aggregates: ~70% of aggregates contain only a root entity with value-typed properties. Large aggregates create concurrency contention, scalability failures, and memory pressure.
-
Reference other aggregates by identity: Use
ProductIdnotProduct. Direct object references create accidental cross-aggregate transactions and prevent independent scaling. -
Use eventual consistency outside the boundary: Domain events communicate across aggregates. One transaction = one aggregate. If you need to update two aggregates "atomically," reconsider your boundaries.
Aggregate Design Checklist
- Contains only elements sharing true invariants
- Root entity controls all access (no direct child manipulation)
- External references by ID only (no object graphs)
- Small enough for single-transaction performance
- Command produces events (in event-sourced systems) or mutates state (in traditional)
- Business rules validated in command handling, not in persistence layer
Common Aggregate Smells
| Smell | Signal | Fix |
|---|---|---|
| God Aggregate | >5 entities, frequent concurrency conflicts | Split by invariant analysis |
| Anemic Aggregate | All logic in services, aggregate = data bag | Move business rules into aggregate methods |
| Cross-Aggregate Transaction | Two aggregates modified in one DB transaction | Use domain events + eventual consistency |
| Deep Nesting | Aggregate root -> entity -> entity -> value | Flatten; promote nested entities to own aggregates |
| Missing Aggregate | Business rules scattered in application services | Identify invariant cluster, create aggregate |
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.

nw-ddd-tactical is a skill published in the GitHub repository nWave-ai/nWave (631 stars, last pushed yesterday), licensed MIT. It adds 32 tokens to every session and 1,456 once invoked, about $0.0001 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.
