Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Professional agent skills for composing and arranging popular music. The licence is MIT.
When your agent uses it
- Arranging city pop
- R&B-adjacent pop
- A track needs that late-night urban sound
- A groove needs to lean forward
Example prompts
- “/mc-style-citypop-rnb”
Workflow steps
10 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 7adca0c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Mc Style Citypop Rnb loads about 1.9k tokens when it runs. Until then it costs about 175 tokens; SKILL.md has 624 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

都会流行与 R&B 风格层（City Pop / R&B）
这个风格的三根支柱：借来的爵士和声、抢拍的贝司、刻意的空。
★ 它是本库里被验证得最充分的风格——
mc-workflow/example-01-citypop.yaml 是一份完整填好的 ARR-SPEC（20 条自查全过），
下面大量内容直接来自它。

| 频段怎么分 | §6（一份实测的频谱预算） |
| R&B 与 city pop 的差别 | §7 |
| 找一份完整范例 | mc-workflow/example-01-citypop.yaml |
边界
| 不归这里 | 归哪 |
|---|---|
| 爵士和声的完整体系 | mc-style-jazz §3、mc-harmony |
| 具体进行（丸サ、逆循环…） | mc-progressions |
| 抢拍拖拍的通用原理 | mc-rhythm-section §3 |
| 频段预算的通用方法 | mc-texture-layering §4 |
| 合成器音色怎么做 | mc-sound-design |
| 演唱设计 | mc-vocal-direction |
1. 动笔前必填
| 必填 | 问法 |
|---|---|
| ① city pop 还是 R&B | ★ 两者的律动与人声完全不同（§7） |
| ② 年代感 | 70s–80s 原版？2010s 复兴版？还是当代 neo-soul？ |
| ③ 律动往前还是往后 | ★ city pop 往前赶，neo-soul 往后坐。这是两个方向 |
| ④ 谁负责"空" | ★ 这个风格的性格来自留白，留白要指定给谁 |
2. ★ 移植表
| 手法 | 可搬出去吗 | 说明 |
|---|---|---|
| 丸サ进行（IV–III7–VIm–I） | ✅ 完全可搬 | 已在 mc-progressions §2.4。"几乎任何旋律放上去都显得时髦" |
| F/G 型分数属代理 | ✅ 可搬 | ≈ G7sus4(9)，比 G7 含蓄精致 |
| 七和弦化 + 适度张力 | ✅ 可搬 | 但密度要控——满编张力会变爵士 |
| 贝司抢拍、鼓守网格 | ✅ ★ 可搬，而且是最值钱的一条 | 见 §4 |
| Rhodes / 电钢的音区限制 | ✅ 可搬 | §5.2 |
| 16 分闷音刷弦 | ⚠️ 半搬 | 很强的风格标记，搬进别的风格会立刻被听成 city pop |
| gated snare | ⚠️ 半搬 | 强 80s 标记 |
| 萨克斯 solo | ⚠️ 半搬 | 同上，且容易显得刻意怀旧 |
| "留白即风格" | ✅ ★ 可搬，该搬 | 见 §8 |
★ 判据：
和声与律动可以自由借；音色（闷音刷弦、gated snare、sax）是标记，借了就会被认出来。
3. 和声
3.1 它借的是爵士，但降了密度
| 来自爵士 | city pop 的用法 |
|---|---|
| 七和弦、九和弦 | ★ 默认就是七和弦，不是"升级选项" |
| 张力音 9/11/13 | 用，但一次一两个，不像爵士满编 |
| 二五、副属 | 大量使用 |
| Sus / 分数属代理 | ★ F/G 是心头好 |
| 变化属、减音阶 lick | ❌ 不用——那会变成爵士 |
★ 这条差别是本 skill 的核心： city pop 的和声是"爵士的词汇 + 流行的语法"。 词汇借满，语法（功能进行、段落、副歌中心）仍然是流行的。
3.2 标志性进行
见 mc-progressions：
- 丸サ进行 4361（
IV–III7–VIm–I）—— city pop / neo-soul 的同义词 IV△7–IIIm7–IIm7–I△7—— 流行/R&B 标准（"Lovin' You"）； ★ 循环回去前插一个 #IVm7(♭5) 非常时髦C△7–D7–F–F/G—— 漂浮感，副属 II7 指向的 V7 始终不来
4. ★ 律动：抢拍贝司 + 守网格的鼓
这是这个风格最可复制、也最常被做错的一条。
实测样本（example-01，112 BPM）：
| 声部 | 偏移 | 作用 |
|---|---|---|
| 贝司 | −12 ms（抢拍） | ★ 这首歌"往前赶"的唯一来源 |
| 干净吉他 | +8 ms（拖） | 与贝司拉开，产生宽度错觉 |
| 鼓 | 0 | ★ 守网格，做参照系 |
4.1 为什么必须有一件守网格
"抢拍"是相对的。 所有人一起抢只是速度快了一点，听不出往前赶。 必须有一个不动的参照物，抢才成立。
★ 这也是 mc-rhythm-section §2.0 那条"量化是逐乐器的决策"在具体风格上的落点。
4.2 贝司与底鼓的关系
city pop 通常用交织式（mc-rhythm-section §7.1）——
需要时重合加厚低频，不需要时拆开，保住贝司自己的旋律线条。
★ 这个风格的贝司是有旋律的，不是只打节奏点。
4.3 feel
straight16（不是 swing）。16 分音符的密度来自闷音刷弦，不是来自摇摆——这两者听感相近，容易混着判断，选错会连累 §4 的抢拍判断（抢拍量的基准是"直"的网格，摇摆网格上"抢拍多少 ms"这个说法本身就不成立）。feel 怎么选的通用步骤（先风格后速度、backbeat 判据、in the crack 这类中间档怎么处理）见 mc-rhythm-section §1.1，这里不重复。
5. 编制
5.1 一份实测的 roster（example-01）
| 乐器 | 角色 | 频段 | 进 / 退 |
|---|---|---|---|
| 原声鼓 + gated snare（70 年代收音） | 律动 | 60 Hz–12 kHz | A1 / end（D 段整段静默） |
| Precision Bass，指弹、短延音 | 低频 | 40–250 Hz | A1 / end |
| Rhodes Mk I + 轻 chorus | 和声铺底 | 200 Hz–2 kHz | I / end |
| Strat 单线圈，16 分闷音刷弦 | 织体 | 1–3 kHz | A1 / C2（★ 之后不再出现，把空间让给萨克斯） |
| Prophet 类锯齿单音，慢滑音 | 记忆点 | 1.5–4 kHz | I / end（★ 只弹 hook，不做垫底） |
| 弦乐群，高把位长音 | 色彩 | 400 Hz–6 kHz | C1 / end（A2 退出一次，C2 再回来） |
| 次中音萨克斯 | 旋律 | 250 Hz–4 kHz | D / O（★ 全曲过半才进场，Outro 是它的） |
| 女声，气声偏多、不贴脸 | 旋律 | 200 Hz–8 kHz | A1 / C3（★ Outro 无人声） |
★ 三处设计都是本库强规则的体现：
- 萨克斯全曲过半才进场 —— 编制必须有中途进场（59/59 强规则）
- 吉他 C2 退场、人声 C3 退场 —— 至少一件提前退场（59/59 强规则）
- 合成器只弹 hook 不垫底 —— 非人声记忆点（lint #8）
5.2 ★ 音区纪律
这个风格最容易糊的地方是 200–500 Hz，因为 Rhodes、弦乐、人声都在那儿。
实测解法：
- Rhodes 限制在 C3–C4
- 弦乐只写 C4 以上
★ 这是"错开音区"的教科书用法（mc-texture-layering §4.2 解法②）。
不是靠 EQ 切，是靠写的时候就不写进去。
Show full SKILL.md (266 more words)Show less
6. 一份实测的频谱预算
| 频段 | 归谁 | 争抢者 | 解法 |
|---|---|---|---|
| 40–120 Hz | 贝司 | 鼓 | Kick 侧链 Bass，30 ms 释放；Bass 在 Kick 击点让出 3 dB（让频） |
| 200–500 Hz | Rhodes | 弦乐、人声 | ★ 错开音区：ep 限 C3–C4，strings 只写 C4 以上 |
| 1–3 kHz | 闷音吉他 | 合成主音 | ★ 交替出现：吉他只在 A/B 段，合成主音只在 I/C/O 段的句尾空档 |
| 6–12 kHz | 鼓 | 弦乐 | 弦乐高频滚降 8 kHz，把空气感留给 hihat |
★ 四条冲突，三种解法都用上了（让频 / 错开音区 / 交替出现）——
这正是 mc-texture-layering §4.2 要求的"三选一并写明"。
7. city pop 与 R&B 的分野
| city pop | R&B / neo-soul | |
|---|---|---|
| 律动方向 | ★ 往前赶（贝司抢拍） | ★ 往后坐（laid back） |
| 人声 | 相对直白，混得靠后 | 大量装饰、转音、ad-lib |
| 和声 | 爵士词汇 + 流行语法 | 更接近爵士，张力更满 |
| 编制 | 乐队编制（鼓贝吉键 + 弦 + 管） | 更依赖采样与编程 |
| 人声叠加 | 副歌加和声 | ★ 和声堆叠是主要手段（mc-vocal-direction §5 四型全用） |
★ 两者共享和声语汇，但律动方向相反。 把 city pop 的抢拍贝司放进 neo-soul 会直接毁掉那个风格。
7.1 ★ 一条实测：R&B 是最"减法"的风格
仓库实测语料 里 hiphop-rnb 10 首：
| 指标 | hiphop-rnb | pop | jazz |
|---|---|---|---|
| 提前退场的乐器数（中位） | ★ 28 | 16 | 10 |
| 开场就在场的乐器比例 | 24% | 21% | 16% |
读法：R&B/嘻哈开场铺得最满，但撤得也最多—— 它的结构感来自不断撤掉东西，不是不断加东西。
★ 可直接搬：写 R&B 时，subtraction_events 要写得比别的风格多。
语料这 10 首是 hiphop-rnb 混装。hip-hop 一侧（第三种时间感、808 分工、采样织体）在
mc-style-hiphop；本节只说 R&B 半边。
7.2 ★ 西洋 R&B 与日本 R&B 是两个东西（藤谷）
| 西洋 R&B | 日本 R&B | |
|---|---|---|
| 音符 | 少 | 多 |
| 气质 | 阴暗、冷酷 | 闪烁、明亮 |
| 和声 | 受爵士影响，常用很复杂的和弦 |
（p0154）。写之前先说清要哪一个，"R&B"这三个字母不够用。原则：音符少的时候，每一个音都要好听，否则编曲不成立； 拍子是 R&B 的命脉，大鼓小鼓的音色要讲究（p0154）。
7.3 西洋向 R&B 的编程定式（藤谷 p0157–0162）
- 鼓全用合成音色，按 hip hop 手法设拍；三件音色都要"像黑胶采样出来的"，厚实粗糙，采样特性是大鼓小鼓响时 hi-hat 也同时共鸣，那就是 groove（p0157）
- 两层大鼓：主大鼓，加一个"噗"一声的超低音大鼓，只出现在小节开头（p0157）
- hi-hat 打八分音符，完全不调力度，淡淡地逐格输入（p0160）；过门放在偶数小节结尾，用刮唱片音效（p0160）
- 贝斯只弹根音，只落在第一拍与第三拍后半的八分音符弱拍上；音符尽量延长但不盖过第二拍第四拍的开头，太长就拖泥带水（p0161）
- 电钢琴只用二分音符或全音符，颤音与音色够好就舒服；别的类型要厚实辽阔感时也用它（p0162）
这与 §4 的 city pop 律动正相反：那边贝司抢拍、鼓守网格；这边贝斯只有两个落点、hi-hat 无力度。同一个"R&B"标签下是两套编制纪律。
8. ★ "留白即风格"
这个风格的性格有一半来自不弹什么。
实测样本里的三个减法事件：
| 位置 | 做什么 | 为什么 |
|---|---|---|
| C2 之前 | 最后半拍全体静止（含鼓） | ★ 第二段副歌不能靠更响赢第一段，靠前面那个洞 |
| D 段 | 鼓与贝斯整段撤出，只剩电钢 + 人声 + 萨克斯 | ★ 全曲能量最低点必须在 C3 之前，否则 C3 不成立 |
| A2 | 弦乐与半数吉他退出 | ★ 第二段主歌要比第一段更空，而不是更满 |
★★ 这三条理由都值得单独记住，它们是通用的编曲智慧，不只属于这个风格
（→ mc-arrangement-arch §3）。
9. 与 ARR-SPEC 的字段对应
| 字段 | 本 skill |
|---|---|
meta.style_layer | mc-style-citypop-rnb |
groove.feel | straight16 |
groove.push_pull | ★ §4 —— 贝司负、鼓 0，这是风格的签名 |
arrangement.spectrum_budget | §6 |
arrangement.roster[].note | ★ 音区限制写在这里（§5.2） |
arrangement.bass_kick_relation | 交织式 |
subtraction_events | §8。R&B 要写得更多（§7.1） |
10. 写完后必过
- 分清了 city pop（往前）还是 R&B（往后）
- 有一件乐器守网格做参照系（§4.1）
- 贝司有旋律线条，不是只打节奏点
- 中低频用错开音区解决，不是靠 EQ 切
- 每处频段冲突都写明了三解法中的哪一种
- ★ 有明确的减法事件，且说得出理由
- 记忆点乐器只弹 hook，不垫底
- 至少一件乐器全曲过半才进场，至少一件提前退场
- 往别的风格搬时，查过 §2——没有把音色标记一起搬走
