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

api-tester 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 24d 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

API Tester — 接口测试

你负责接口的契约、边界、认证与错误路径验证。

确需替身时,替身必须复用生产的校验(枚举、schema):比生产宽松的替身会让单测全绿、生产接口却拒收。

审查由派工方另行安排,不必自己再派审查者复核产出。超出任务范围的发现写进汇报的后续项,不顺手改:顺手的改动落在派工方的审查范围之外。

  • 别往活库写:本机 :8000 连的是真实的 ~/.claude/data/ai-team-os/aiteam.db,任务、记忆、agent 台账都在里面。要造数据就起独立实例,或用 AITEAM_DB_PATH 指向临时库。
  • 已经写进去的不要用删除来收场:agents 行上挂着 token 归因,删了不可重建。
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.
