What is fleet-hygiene?

A set of safety and data-handling rules for assistants working in a shared organisation. The rules cover Google Drive writes, automated logins, credentials, scripts, and other people's data.

Use it before writing to Google Drive, automating access to an external service, handling login details, or requesting another party's data.

It reduces the risk of writing files to the wrong place, exposing credentials, or accessing another customer or assistant's information.

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	$0.00178	$0.01420
Opus 5.5	$0.00071	$0.00568
Sonnet 5.5	$0.00036	$0.00284
Haiku 4.5	$0.00018	$0.00142

Security

Grade A, and why

fleet-hygiene 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 1mo 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.

The opening of the file, as written. The whole thing — 41 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Flotta-higiénia (általános, megszeghetetlen)

Ezek a Marveen-flotta minden kolléga-asszisztensére érvényes, telepítéstől független szabályok. A te telepítésedre jellemző, owner-specifikus kiegészítéseket (konkrét közös Drive-mappa, helyi MCP-k, kód-fejlesztési tiltás) a saját CLAUDE.md "Flotta-szabályok" blokkja tartalmazza. Ütközés esetén a szigorúbb szabály nyer; ha bizonytalan vagy, kérdezd meg a Marveen Főnököt (a flotta main agentjét) inter-agent üzenettel.

Mikor használd

Mielőtt bármit Google Drive-ba írnál (doksi, táblázat, eredmény-fájl).
Mielőtt külső szolgáltatásba automatikus bejelentkezést, jelszó-/credential-kezelést, vagy futtatható szkriptet (Playwright/böngésző-automatizálás, scraper, login-szkript) írnál vagy futtatnál.
Amikor egy másik ügynök vagy megbízó adatait, postáját, credentialjét kérnéd vagy adnád ki.

Eljárás

1. Drive-írás hatóköre

Írni KIZÁRÓLAG a kijelölt helyre szabad: egy megadott Google Drive mappába VAGY egy külön megosztott meghajtóba (Shared Drive). Ha megosztott meghajtó áll rendelkezésre, ott létrehozhatsz almappákat, és rendezetten helyezd el a doksikat.
A KONKRÉT közös mappát a saját CLAUDE.md "Flotta-szabályok" blokkja adja meg (a dashboard Beállítások OWNER_DRIVE_FOLDER kulcsából generálva). Ha ott nincs kijelölt mappa, MIELŐTT bárhova írsz, kérd el a tulajdonostól. Ne találgass, ne írj máshova.
Saját ("My Drive") meghajtóra írni TILOS.
Olvasni a teljes Drive-ot szabad.
Az elkészült eredmény-fájlokat külön kérés nélkül is a közös mappába tedd, rendezett almappákba.

2. Login-automatizálás / credential / futtatható szkript -> ELŐBB szólj a Főnöknek

Mielőtt bármilyen külső szolgáltatásba automatikus bejelentkezést, jelszó-/credential-kezelést, vagy futtatható szkriptet írsz vagy futtatsz, jelezd a Marveen Főnöknek (a flotta main agentjének) inter-agent üzenettel. Ő koordinálja és a tulajdonossal egyezteti.
Credential-t SOHA ne égess nyersen kódba. Ha titok kell, kérd a Főnöktől a biztonságos tárolás módját.

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.
