project-ddd

project-ddd is a skill for Claude Code from nasrulhazim/claude. It costs 252 tokens per session (3,756 once invoked), scanned A, original, MIT.

A practical way to organise Laravel applications around business areas, called domains, instead of keeping unrelated code in one flat structure. Domain-Driven Design means shaping code around the business problems it serves.

In plain words
What is it for?
Use it to identify business boundaries, plan a Laravel restructure, create domain folders and layers, migrate existing code, and connect domains.
Why use it?
It clarifies ownership, reduces accidental dependencies between business areas, and can make changes and onboarding easier.

Token cost

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.

Security

Grade A, and why

project-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 5d 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.

The opening of the file, as written. The whole thing — 474 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Domain-Driven Design — Pragmatic Laravel

Restructure Laravel applications into domain-based organisation. Business objectives first — increase revenue, reduce OPEX, ship faster. Not academic DDD, but practical domain separation that your team can maintain.

Philosophy

"Kita orang meniaga nak increase sales, kurangkan OPEX. Bukan nak berfilasuf pasal kod."

This skill applies DDD where it creates real business value:

  • Clear ownership — each domain maps to a business capability, team knows what they own
  • Independent velocity — domains can evolve without breaking each other
  • Reduced OPEX — less accidental complexity, faster onboarding, fewer cross-cutting bugs
  • Business alignment — code structure mirrors how the business actually works

Command Reference

Command Description
/project-ddd discover Interview to identify bounded contexts from business processes
/project-ddd plan Generate migration plan from flat Laravel to domain structure
/project-ddd scaffold Scaffold a new domain with all layers
/project-ddd migrate Move existing code into domain structure (guided, step-by-step)
/project-ddd wire Create/update domain service providers and autoloading
/project-ddd test Update architecture tests for DDD structure
/project-ddd audit Check existing domain structure for violations


Companion: graphify

graphify builds a persistent, queryable knowledge graph of a codebase — tree-sitter AST parsing for code plus semantic extraction for docs. It answers structural questions far faster than grepping, and it is installed by default with this toolkit.

Use it before a manual sweep whenever the question is structural.

graphify extract .                       # build (or refresh) the graph — once per repo
graphify query "how does authentication work"
graphify path UserController InvoiceRepository   # call chain between two nodes
graphify explain app/Services/BillingService.php

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.
