  • Prompt-injection patterns
  • Secret / credential exfiltration

  • Known-malicious package signatures

What it can access

  • Network access No
  • Filesystem access No
  • Shell / process execution No
  • Environment & secrets No
  • Dynamic code execution No

From automated source analysis of v0.1.0. “Used” means the capability is present in the source — more access means more to trust, not that it’s unsafe.

Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

数值调谐参考

术语

| 名称 | 含义 | | --- | --- | | current | 当前数值 | | target | 目标数值 | | delta | 本轮施加的扰动量(带方向 + 随机噪声) | | new | current + delta | | gap | \|new - target\| —— 距离目标剩余距离 | | 收敛 | gap < 0.5 |

公式(apply_delta 内部)

direction = sign(target - current)
magnitude = uniform(0.3, 1.5) * |target - current| * 0.4
delta     = direction * magnitude

平均步长 = 40% 距离,但 0.3–1.5 倍随机系数 → 有概率 overshoot。 overshoot 后下一轮方向反转,继续收敛。这就是「震荡回归」。

收敛通常需 5-10 轮。
