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

slack 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 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.

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.

Origin

This is a copy

84% identical to slack — 11 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Slack Actions

Overview

Use slack to react, manage pins, send/edit/delete messages, and fetch member info. The tool uses the bot token configured for Moltis.

Inputs to collect

  • channelId and messageId (Slack message timestamp, e.g. 1712023032.1234).
  • For reactions, an emoji (Unicode or :name:).
  • For message sends, a to target (channel:<id> or user:<id>) and content.

Message context lines include slack message id and channel fields you can reuse directly.

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.
