dev-new

A development command for starting a new project with architecture planned before implementation. It follows a greenfield development workflow, meaning the software is being built from the beginning.

In plain words
What is it for?
Use it for new applications or major greenfield work that needs an architecture plan, phased development, and quality checks.
Why use it?
It helps establish the project's structure and technical decisions before coding begins, reducing uncertainty during implementation.

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

dev-new 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 2d 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.

Execute

  1. Read skills/auto-dev/SKILL.md and skills/auto-dev/config/defaults.json
  2. Read the paradigm: skills/auto-dev/paradigms/dev/architecture-first.md
  3. Follow the paradigm's phase sequence — read each phase file when entering it, not all upfront
  4. Respect quality gates at every phase boundary

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.
