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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00653 | $0.00653 |
| Opus 5 | $0.00327 | $0.00327 |
| Sonnet 5 | $0.00131 | $0.00131 |
| Haiku 4.5 | $0.00065 | $0.00065 |
Grade A, and why
ai-dev-operating-system CLAUDE.md 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.
How it starts
The opening of the file, as written. The whole thing — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md — AI Dev Operating System
This file defines how Claude Code and other AI coding agents should behave inside this repository.
The purpose of this repo is to provide a day-zero operating system for AI-assisted SaaS development: rules, agents, skills, commands, documentation layers, sprint system, changelog discipline, session logs, security gates, and prototype workflows.
Golden rules
- Do not code before context.
- Use
START-HERE.mdandWIZARD.mdfor new projects. Prototype (Phase 3) before specifying (Phase 4). - Keep documentation layers separate.
- Preserve decision memory in
session-log/. - Human review is mandatory for BP v0.0.1 before BP v0.0.2.
- Use multi-agent review when relevant.
- No invented facts in market, competitor, legal, pricing, or regulatory claims.
- Use separation of concerns and keep code files under 200 lines where practical.
- Generated code files should include purpose/version/sprint headers.
- Use stable dependencies by default; avoid alpha/beta unless explicitly accepted.
Required generated artifacts for a new project
Listed in the order the wizard produces them:
knowledge-base/README.md (Phase 2)
docs/business/BUSINESS-PLAN.md (Phase 2)
docs/business/PITCH.md (Phase 2)
prototype-lab/README.md (Phase 3)
docs/product/DESIGN-DIRECTION.md (Phase 3)
docs/product/PRODUCT-BRIEF.md (Phase 4)
docs/technical/TECHNICAL-PLAN.md (Phase 4)
docs/SPRINTS.md (Phase 4)
CODEMAP.md (Phase 5, generated from the code)
CHANGELOG.md
session-log/INDEX.md
session-log/YYYY-MM-DD-project-genesis.md
Project Genesis Wizard
The canonical wizard is WIZARD.md. It runs in 5 phases:
| Phase | Name | Produces |
|---|---|---|
| 1 | Largada | detached repo, project intro |
| 2 | Ideação | research, red team, BP v0.0.2 |
| 3 | Protótipo | brand, color, UI, UX — three clickable directions, one approved, and docs/product/DESIGN-DIRECTION.md written as the bridge into Phase 4 |
| 4 | Documentação | Product Brief + Technical Plan reverse-engineered from the prototype, then the roadmap |
| 5 | Chegada | Sprint 0 / Sprint 1 |
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.
