fleet-helper

fleet-helper is a skill for Claude Code from Szotasz/marveen. It costs 86 tokens per session (1,265 once invoked), scanned A, original, MIT.

A set of dependency-free Python helpers for an agent fleet, meaning several cooperating agents. It includes dashboard and Kanban access, memory and messaging helpers, Telegram text escaping, and rule-based unread Mail.app filtering.

In plain words
What is it for?
Use it to read or filter Kanban items and email, save or search memory, send agent messages, format Telegram messages, and build heartbeat checks.
Why use it?
It moves repeatable fetching, filtering, formatting, and message preparation into scripts instead of having the agent redo that work in each session.

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 A, and why

fleet-helper 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 8d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/fleet.py, scripts/gate_example.py, scripts/mail_triage.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

fleet-helper

Move deterministic work (fetch / filter / SQL / format / escape) out of the model and into Python, so heartbeats and scheduled tasks stop spending tokens re-deriving the same plumbing each cycle. Python 3 stdlib only, no pip deps.

No secrets or personal data are baked in: the dashboard token is read from store/.dashboard-token at call time, the project root comes from CLAW_DIR (or is auto-detected), and any personal sender/keyword lists live in a gitignored mail_rules.json (see scripts/mail_rules.example.json).

When to use

  • Saving/searching memory, posting daily-log, sending inter-agent messages.
  • Reading kanban (due today / stuck / by status) without writing SQL by hand.
  • Escaping text for a Telegram MarkdownV2 message.
  • An email heartbeat: pre-filter unread mail to a compact JSON before the model reasons about it.
  • Building a token-cheap heartbeat gate (see "The heartbeat gate pattern" below).

Scripts

  • scripts/fleet.py - dashboard API + kanban read helpers + MarkdownV2 escaper (CLI and importable module).
    • KET escaper van, es a rossz valasztas nemitja a formazast (2026-08-28-i meres). mdv2 MINDENT escapel, a *-ot IS: az *felkover* markereidbol \*felkover\* lesz, tehat sima szoveg. Ez akkor helyes, ha PROGRAMBOL rakod ossze az uzenetet (escapeled a dinamikus reszt, aztan te teszed ra a *-ot). KEZZEL IRT hosszu uzenethez (reggeli napindito) mdv2b kell: az a *-ot meghagyja, minden mast escapel, ES kuldes elott lefuttatja az outgoing_gate_check-et (em dash, --, paratlan csillag). Ha talal valamit, exit 2 es NEM ad kimenetet.
  • scripts/mail_triage.py - rule-based unread Mail.app filter (macOS), JSON out, never sends and never marks read.
  • scripts/gate_example.py - reference heartbeat gate; its shell invocation IS the mandatory keep-alive tool call (the LLM turn is not skipped, just cheap).
  • scripts/mail_rules.example.json - copy to mail_rules.json (gitignored) with your real senders/keywords.
  • scripts/README.md - full usage and the heartbeat gate pattern write-up.

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.
