Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00073 | $0.02724 |
| Opus 5.5 | $0.00029 | $0.01090 |
| Sonnet 5.5 | $0.00015 | $0.00545 |
| Haiku 4.5 | $0.00007 | $0.00272 |
Grade A, and why
pywayne-dsp 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.

Pywayne Dsp
数字信号处理工具集,提供滤波器、峰值检测、去趋势、曲线相似度等信号处理功能。
Quick Start
from pywayne.dsp import butter_bandpass_filter, peak_det, SignalDetrend
# Butterworth 低通滤波
filtered = butter_bandpass_filter(signal, order=3, lo=0.5, hi=40, fs=250)
# 峰值检测
peaks, valleys = peak_det(signal, delta=0.5)
# 信号去趋势
detrender = SignalDetrend(method='linear')
detrended = detrender(raw_signal)
Filtering - 滤波器
butter_bandpass_filter
巴特沃斯带通滤波器。
from pywayne.dsp import butter_bandpass_filter
# 带通滤波
filtered = butter_bandpass_filter(
signal=raw_signal,
order=4,
lo=1,
hi=50,
fs=250,
btype='bandpass'
)
参数说明:
| 参数 | 类型 | 说明 |
|---|---|---|
signal |
array | 输入信号 |
order |
int | 滤波器阶数 |
lo |
float | 下限截止频率 (Hz) |
hi |
float | 上限截止频率 (Hz) |
fs |
float | 采样频率,默认为 0(不归一化) |
btype |
str | 滤波器类型:'lowpass', 'highpass', 'bandpass', 'bandstop' |
realtime |
bool | 是否实时处理,默认 False |
ButterworthFilter
基于 NumPy 的巴特沃斯滤波器类,同时支持传递函数 ba 和数值更稳定的二阶节级联 sos。
BA/SOS 执行核心均为 Direct Form II Transposed,对齐 SciPy 的 lfilter/sosfilt 和
filtfilt/sosfiltfilt。
from pywayne.dsp import ButterworthFilter
# 方式 1:通过参数设计 BA
bf = ButterworthFilter.from_params(order=4, fs=200, btype='bandpass', cutoff=(1, 50))
y, zf = bf.lfilter(signal)
# 方式 2:通过系数构造
bf2 = ButterworthFilter.from_ba(b, a)
y, zf = bf2.lfilter(signal)
# 方式 3:SOS(高阶、窄带或接近 0/Nyquist 时推荐)
bf_sos = ButterworthFilter.from_params(
order=8,
fs=200,
btype='bandpass',
cutoff=(0.1, 10),
output='sos',
)
# 也可直接使用 scipy.signal.butter(..., output='sos') 的系数
bf_sos2 = ButterworthFilter.from_sos(sos)
# 零相位滤波(前向-后向)
y = bf.filtfilt(signal)
# 流式处理:首段稳态初始化,后续传递 zf
state = bf_sos.zi() * chunks[0][0]
outputs = []
for chunk in chunks:
y, state = bf_sos.lfilter(chunk, zi=state)
outputs.append(y)
# 去趋势
detrended = ButterworthFilter.detrend(signal, method='linear')
参数设计方法:
ButterworthFilter.from_params(order, fs, btype, cutoff, cache_zi=True, output='ba')
ButterworthFilter.from_ba(b, a, cache_zi=True)
ButterworthFilter.from_sos(sos, cache_zi=True)
ButterworthFilter.lfilter_zi(b, a)
ButterworthFilter.sosfilt_zi(sos)
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.

pywayne-dsp is a skill published in the GitHub repository wangyendt/wayne-skills (9 stars, last pushed 7d ago), licensed MIT. It adds 73 tokens to every session and 2,724 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
