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.

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 | $0.00071 | $0.01835 |
| Opus 5 | $0.00036 | $0.00918 |
| Sonnet 5 | $0.00014 | $0.00367 |
| Haiku 4.5 | $0.00007 | $0.00184 |
Grade A, and why
chip-cbb-decision 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 11d 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.

CBB 抽象决策器
评估 RTL 逻辑是否应该抽象为 CBB 模块。chip-code-writer 在模块结构规划阶段调用。
输入
| 参数 | 类型 | 必需 | 说明 |
|---|---|---|---|
| logic_description | string | 是 | 待评估逻辑的功能描述 |
| interface_signals | object[] | 是 | 接口信号列表（名称、方向、位宽） |
| reuse_scenarios | string[] | 是 | 潜在复用场景描述 |
| param_candidates | string[] | 否 | 可参数化的候选参数 |
输出
| 参数 | 类型 | 说明 |
|---|---|---|
| decision | string | abstract_to_cbb / keep_inline |
| score | object | 四维度评分 |
| reason | string | 决策理由 |
| cbb_spec | object | 如决定抽象，输出 CBB 规格建议 |
四维度评估
维度 1：接口标准化（权重 30%）
| 分值 | 条件 |
|---|---|
| 3 | 输入输出格式可在 3+ 场景完全复用，无需修改 |
| 2 | 输入输出格式可在 2 场景复用，需少量参数调整 |
| 1 | 接口高度定制化，仅当前场景适用 |
维度 2：参数可配置（权重 25%）
| 分值 | 条件 |
|---|---|
| 3 | 核心参数（位宽、深度、通道数等）全部可通过 parameter 化 |
| 2 | 部分参数可配置，部分硬编码 |
| 1 | 核心逻辑依赖运行时值，无法参数化 |
维度 3：功能自包含（权重 25%）
| 分值 | 条件 |
|---|---|
| 3 | 不依赖外部上下文或状态，纯组合/时序逻辑 |
| 2 | 依赖少量外部信号（如时钟、复位、使能） |
| 1 | 依赖模块特定的上下文数组或状态 |
维度 4：复用价值（权重 20%）
| 分值 | 条件 |
|---|---|
| 3 | 至少 3 处使用，或代码量 > 100 行 |
| 2 | 2 处使用，或代码量 50~100 行 |
| 1 | 仅 1 处使用，且代码量 < 50 行 |
决策规则
总分 = Σ(维度分值 × 权重)
总分 ≥ 2.4 → abstract_to_cbb
总分 < 2.4 → keep_inline
强制不抽象条件（任一满足直接 keep_inline）
- 动态范围：搜索/迭代次数由运行时值决定
- 位图依赖：有效性检查依赖动态位图/掩码
- 上下文耦合：需要访问模块特定的上下文数组
- 接口不兼容：与标准 CBB 接口差异 > 3 个信号
执行步骤
读取输入 → 四维度评分 → 检查强制不抽象条件 → 输出决策

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.
- 11d ago First seen · 169 lines · 71 tokens per session scan A 40e539a6c7fe
chip-cbb-decision is a skill published in the GitHub repository zhaixin244-wq/fnw (29 stars, last pushed 3mo ago), licensed MIT. It adds 71 tokens to every session and 1,835 once invoked, about $0.0004 per session on Opus 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 2026-08-30.
