scaffold-logic

A command that creates an ArchiPy logic class for a chosen domain and operation. The generated class uses domain data objects, receives its repository through its constructor, and wraps database work in a transaction.

In plain words
What is it for?
Use it to start synchronous or asynchronous logic classes with a repository dependency and the appropriate PostgreSQL, SQLite, StarRocks, or SQLAlchemy transaction decorator.
Why use it?
It removes repetitive setup when creating application logic and helps keep business code separate from web or RPC frameworks. The transaction wrapper groups database changes safely.

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.

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

scaffold-logic 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 yesterday.

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

/scaffold-logic

Follow the scaffold-archipy-logic skill.

  1. Ask for domain, logic name, and sync vs async atomic.
  2. Generate logics/<domain>/<name>_logic.py with domain DTO I/O and @postgres_sqlalchemy_atomic_decorator (or async twin).
  3. Inject repository via constructor; no FastAPI/gRPC imports.

Changes

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.

scaffold-logic is a command published in the GitHub repository SyntaxArc/archipy-plugin (2 stars, last pushed 8d ago), licensed MIT. It adds 18 tokens to every session and 128 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.
