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.

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 | $0.02814 | $0.02814 |
| Opus 5 | $0.01407 | $0.01407 |
| Sonnet 5 | $0.00563 | $0.00563 |
| Haiku 4.5 | $0.00281 | $0.00281 |
Grade A, and why
catatz AGENTS.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 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.
How it starts
The opening of the file, as written. The whole thing — 212 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CatatZ - Codex Operating Instructions
Origin
CatatZ adalah aplikasi pencatatan keuangan berbasis Next.js 16 App Router, Supabase, Server Actions, dan PWA Serwist. File ini adalah instruksi repository-level untuk agent saat bekerja dari root repository CatatZ.
Instruksi detail tetap berada di docs/ai-development-rules.md. Anggap file ini sebagai operating manual singkat yang mengikat Codex agar setiap task selesai dengan perubahan yang rapi, dokumentasi yang sinkron, validasi yang jujur, dan suggested commit message yang teknis.
Source of Truth
Ada beberapa sumber kebenaran yang harus dipakai sebelum membuat perubahan:
- Source code saat ini adalah kebenaran utama untuk behavior aplikasi.
docs/adalah kebenaran dokumentasi dan harus mengikuti behavior aktual, bukan rencana.docs/ai-development-rules.mdadalah kebenaran utama untuk aturan kerja AI di repo ini.DESIGN.mdadalah kebenaran utama untuk semua keputusan visual, design token, dan component styling.docs/frontend-guidelines.mdadalah kebenaran implementasi desain di codebase ini (adaptasi DESIGN.md ke Tailwind/shadcn).src/migrationsadalah lokasi migration project ini. Jangan mengasumsikansupabase/migrations..env.examplehanya boleh berisi nama variable dan placeholder aman. Jangan expose nilai secret dari.env.
Jika dokumentasi dan source code berbeda, percaya source code dulu, lalu update dokumentasi yang relevan dalam task yang sama.
ECC Workflow Overlay
CatatZ memakai subset Everything Claude Code (ECC) secara project-local untuk Codex dan Claude Code.
.agents/skills/adalah canonical skill surface..claude/skills/hanya berisi wrapper kompatibilitas yang menunjuk ke canonical skill.- Gunakan skills
coding-standards,frontend-patterns,security-review,verification-loop,documentation-lookup,strategic-compact,agent-introspection-debugging,product-capability,tdd-workflow, dane2e-testingsesuai task. nextjs-turbopackadalah library reference, bukan aturan production build. Production CatatZ tetap memakainext build --webpackuntuk Serwist.- Specialized agents di
.codex/agents/dan.claude/agents/bersifat read-only. Main agent adalah satu-satunya pihak yang boleh mengedit file. - Hooks project memblokir command destruktif dan perubahan secret file, tetapi quality check hanya warning. CI tetap menjadi enforcement utama.
- Memory hook hanya boleh menyimpan metadata di
.ecc/runtime/: path file, status verifikasi, timestamp, dan identifier sesi yang sudah di-hash. Jangan simpan prompt, tool arguments, isi file, secret, atau data finansial. - MCP project hanya
chrome-devtools. Jangan tambahkan Supabase, database production, GitHub, memory, atau connector lain tanpa review eksplisit.
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.

catatz AGENTS.md is an instructions file published in the GitHub repository kupzed/catatz (33 stars, last pushed yesterday), licensed MIT. It adds 2,814 tokens to every session, about $0.0141 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 2026-09-01.
