dark-factory-build

dark-factory-build is a skill for Claude Code from OneDro1d/dark-factory. It costs 73 tokens per session (3,561 once invoked), scanned A, original, Apache-2.0.

An end-to-end software-building process that turns a specification into tested, verified, documented, and shipped software. It breaks the work into defined stages and can run autonomously in development or non-production environments.

In plain words
What is it for?
Use it to take a non-trivial feature or partly built project from requirements through design, test-first implementation, verification, and delivery. It also creates the tickets and documents needed to explain the work.
Why use it?
It prevents features from being treated as finished based only on the builder’s claims. Each stage has tests, independent checks, and recorded evidence so missing work and faulty assumptions are easier to find.

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

dark-factory-build 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 10d 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.

Dark Factory Build — end-to-end orchestrator

Overview

This skill runs a complete Dark Factory build: intent → semantics → design → tests → code → verification → live proof → shipped + documented. It is the conductor; the per-stage df-* skills do the work. Everything is modeled through the data-transform lens (data nodes + pure/effect transforms + validation rules + authority), built test-first, verified adversarially (never on a self-report), executed autonomously in dev/non-prod, and documented as tickets + DF spec docs + memory at every step.

It is the generalization of a real run: a DEX arbitrage bot taken from half-finished to a liquidity-aware arbitrage engine with 5 DF docs, TDD + ~290k-case adversarial fuzz, and a live on-chain no-overshoot proof — all ticketed and committed.

When to use

  • "Build this the dark factory way" / "run a DF build" / "do this end-to-end autonomously."
  • A spec or half-built project needs to be finished with docs + TDD + verification + tickets.
  • Any non-trivial feature where you want the full discipline: semantics first, blind-verified, evidence-backed.

For a single stage only (just the PO doc, just TDD), invoke that df-* skill directly instead.

The pipeline

Run the stages in order. Each stage has an owning df-* skill, a concrete artifact, and a ticket. Earlier stages gate later ones (a cold reader must be able to build the next stage from the previous artifact alone).

You MUST call the owning skill before producing that stage's artifact. Reading this table is not running the stage. The table tells you which skill owns the stage; the skill itself carries the checklist, the required artifact shape, and the verification steps — none of which are reproduced here, and all of which are silently skipped if you write the doc directly.
