What is vibe-coder-kit AGENTS.md?

A set of instructions for an AI coding agent working in an OpenCode project. It defines required startup steps, safety checks, coding standards, and a workflow for planning and implementing changes.

Use it to guide new coding sessions, protect data during database or Git operations, manage environment variables, keep code maintainable, and structure work from ideas through implementation.

It gives the agent consistent project context and reduces risks such as destructive commands, leaked secrets, unfinished cleanup, and mixed feature and refactoring work.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00728	$0.00728
Opus 5.5	$0.00291	$0.00291
Sonnet 5.5	$0.00146	$0.00146
Haiku 4.5	$0.00073	$0.00073

Security

Grade C, and why

vibe-coder-kit AGENTS.md scanned grade C with 1 finding 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 2mo 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

- `DROP`, `DELETE`, `TRUNCATE`, `rm -rf`, `git push --force` (ana branch): **Onay al before running**

OpenCode Agent Setup

Bu dosya opencode tarafından her oturumda otomatik okunur.

Zorunlu İlk Adım

Her yeni oturumda .agent/skills/project-context-primer/SKILL.md oku ve uygula. Bu atlanmaz.

Kritik Kurallar

Güvenlik

DROP, DELETE, TRUNCATE, rm -rf, git push --force (ana branch): Onay al before running
Mevcut testler geçiyorsa ve görev o kodu doğrudan değiştirmiyorsa — dokunma
Migration/production deploy öncesi: rollback adımı tanımla

Kod Temizliği

Yorumlar sadece fonksiyon/metot başlıklarında
console.log, console.warn, debugger, print(): commit öncesi kaldır
Hassas değerler (API key, token): .env kullan, kesinlikle koda yazma
Yeni env variable eklendiğinde: .env.example güncelle (açıklama zorunlu)

Kod Kalitesi

Aynı kod 3+ yerde tekrar ediyorsa → extract et
Yeni soyutlama öncesi: "3+ yerde kullanılıyor mu? 6 ay sonra anlaşılır mı?" → Hayır ise bırak
Refactor: feature commit'inden ayrı, bağımsız commit

İş Akışı

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.
