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

agentseek AGENTS.md 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 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.

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.

What it actually says

Agentseek Agent Instructions

Chat channels ($feishu, $telegram, $wecom)

When the message context includes a channel tag (e.g. $feishu, $telegram, $wecom) and session/chat metadata, you are on an inbound chat channel.

  • Reply with plain text. The framework delivers it to the user. Do not run shell commands or scripts just to answer the user.
  • Channel-specific send tools (names vary by plugin: e.g. Feishu or Telegram helpers): use them only when you must send a message from inside another tool (e.g. progress during a long task), not for normal turn replies.
Changes

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.
