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 | $0.00070 | $0.04523 |
| Opus 5 | $0.00035 | $0.02261 |
| Sonnet 5 | $0.00014 | $0.00905 |
| Haiku 4.5 | $0.00007 | $0.00452 |
Grade A, and why
tactical-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 7d 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 — 549 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tactical DDD
Design, refactor, analyze, and review code by applying the principles and patterns of tactical domain-driven design.
This codebase's conventions
This codebase targets .NET 8. It originated on an old .NET version and is being modernized as it is enriched — write idiomatic modern C#, do not copy the legacy style:
- File-scoped namespaces (
namespace Foo;), not bracketed blocks. - Value objects as
record/readonly record struct— you get value equality,ToString, and immutability for free, so do NOT hand-rollEquals/GetHashCode. Useinit-only /requiredmembers and a static factory (or a validating primary constructor) so an instance cannot exist in an invalid state. EF Core maps these via owned types / value converters — keep a way for EF to materialize them, but don't let EF needs dictate a mutable, ctor-less data bag. - Nullable reference types enabled; use them to make "must exist" vs "may be absent" explicit rather than relying on runtime null checks.
- Invariants: throw a domain-specific exception (or return a result type) from the factory /
method that enforces them — not a generic
Exception, and not validation scattered in services. - Layers:
Domain/(entities, value objects, invariants),Application/(services that orchestrate),Controllers/(HTTP + DTOs),Infrastructure/(EF Core config). Domain holds no EF or ASP.NET references. - Keep the public API (controllers, DTOs, endpoints) unchanged when refactoring internals.
Principles
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.

tactical-ddd is a skill published in the GitHub repository NoesisVision/nasde-toolkit (12 stars, last pushed yesterday), licensed MIT. It adds 70 tokens to every session and 4,523 once invoked, about $0.0003 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.
