beyin-doktor

beyin-doktor is a skill for Claude Code from avenoxai/avenoxbeyin. It costs 109 tokens per session (4,545 once invoked), scanned C, original, MIT.

A read-only health check for an agent’s working memory system, including its hooks, scripts, logs, build status, and stored files.

In plain words
What is it for?
Use it to inspect the memory setup, classify each check as healthy, uncertain, or failed, and list a correction for each failed check.
Why use it?
It helps reveal silent failures, such as a hook that no longer runs or logs that have become outdated.

Skill for Claude Code

Written for Claude Code: SessionStart hook event. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is test -L AGENTS.md && [ "$(readlink AGENTS.md)" = "CLAUDE.md" ] && echo "router: ortak" || echo "router: AYRI/YOK"; test -L .agents/skills && [ "$(readlink .agen.

Good fit Use it to inspect the memory setup, classify each check as healthy, uncertain, or failed, and list a correction for each failed check.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 C, and why

beyin-doktor scanned grade C with 2 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 6d 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.

Beyin Doktoru

Bu skill beynin mekanik katmanını denetler: hook'lar tetikleniyor mu, script'ler çalışmış mı, loglar tazeliğini koruyor mu, vault kirlenmiş mi. Amaç sessiz arızayı görünür yapmak.

Nasıl çalışırsın

  1. Vault kökünde (CLAUDE.md/AGENTS.md'nin bulunduğu klasör) çalış. Tüm yollar göreceli, mutlak yol yazma.
  2. Aşağıdaki kontrolleri Bash ile sırayla çalıştır. Komutları olduğu gibi kullan, tahmin etme.
  3. Her kontrolün çıktısını 🟢 / 🟡 / 🔴 olarak sınıfla.
  4. Sonucu tek bir tabloda ver, her 🔴 için bir düzeltme satırı yaz.
  5. En sonda tek cümlelik hüküm ver.

Kontroller salt okunurdur. Hiçbir şeyi kendiliğinden düzeltme, önce raporla, sonra kullanıcı isterse düzelt.

Kontroller

1. Hook dosyaları var mı ve çalıştırılabilir mi

for h in session-start prompt-counter session-end pre-compact; do f=".claude/hooks/$h.sh"; if [ ! -f "$f" ]; then echo "$h: DOSYA YOK"; elif [ ! -x "$f" ]; then echo "$h: calistirilabilir degil"; else echo "$h: ok"; fi; done

🟢 dördü de ok. 🔴 eksik veya çalıştırılabilir değil. Düzeltme: chmod +x .claude/hooks/*.sh, dosya yoksa depodan kopyala.

2. Hook'lar settings.json içinde bağlı mı

for h in session-start prompt-counter session-end pre-compact; do if grep -q "$h.sh" .claude/settings.json 2>/dev/null; then echo "$h: bagli"; else echo "$h: SETTINGS ICINDE YOK"; fi; done

🟢 dördü de bağlı. 🔴 biri bile eksikse o hook hiç çalışmıyor demektir. Düzeltme: .claude/settings.json içindeki hooks bloğuna eksik olayı ekle (SessionStart, UserPromptSubmit, SessionEnd, PreCompact), sonra Claude Code'u yeniden başlat.

3. Özyineleme koruması her hook'ta var mı

for f in .claude/hooks/*.sh; do if grep -q 'BEYIN_INVOKED_BY' "$f"; then echo "$(basename "$f"): guard var"; else echo "$(basename "$f"): GUARD YOK"; fi; done

🟢 hepsinde var. 🔴 eksik. Guard'ı olmayan hook, arka plan claude -p çağrısında tekrar tetiklenir ve sonsuz döngü riski doğar. Düzeltme: dosyanın shebang'inden hemen sonraki satıra [ -n "${BEYIN_INVOKED_BY:-}" ] && exit 0 ekle.

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.
