ai-dev-operating-system: Skill for Claude Code

.claude/skills/project-genesis/SKILL.md

project-genesis is a skill for Claude Code from lglucas/ai-dev-operating-system. It costs 102 tokens per session (414 once invoked), scanned A, original, MIT.

A guided five-phase process for turning a raw idea into the first coding sprint. It covers understanding the repository, shaping the idea, making a prototype, writing the product and technical plans, and starting development.

In plain words
What is it for?
Starting an app or SaaS project, exploring the idea, approving a prototype, choosing the technical approach, and planning the first sprint.
Why use it?
It gives a new project a defined order of work and checkpoints before coding begins.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is lglucas/ai-dev-operating-system's own configuration. It tells Claude Code how to work on ai-dev-operating-system itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ai-dev-operating-system configures →

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-genesis 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.

What it actually says

Project Genesis Skill

Use this skill when starting a new project from the AI Dev Operating System.

Follow WIZARD.md exactly. It runs in 5 phases, and none may be skipped:

Phase Must include
1 — Largada repository comprehension, detach from OS-origin, friendly opening
2 — Ideação raw ideation, ten questions, research plan approval, three research/review waves, BP v0.0.1, human review, BP v0.0.2
3 — Protótipo design pack pick, Prototype Lab (3 directions), direction approved, DESIGN-DIRECTION.md written
4 — Documentação Product Brief, Technical Plan, stack pack pick, sprint roadmap
5 — Chegada Sprint 0 / Sprint 1

The one ordering mistake to avoid

Phase 3 comes before Phase 4. Prototype first, then reverse-engineer the Product Brief and Technical Plan from the direction the user approves.

Do not write the Product Brief and then prototype against it. That was the order until v0.4.5 and it was inverted deliberately: a spec written against a clickable prototype names the gaps that a spec written against a paragraph quietly invents.

If the prototype seems to need the Product Brief, what it actually needs is missing from BP v0.0.2. Go back and add it there.

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.
