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 | $0.00088 | $0.01438 |
| Opus 5 | $0.00044 | $0.00719 |
| Sonnet 5 | $0.00018 | $0.00288 |
| Haiku 4.5 | $0.00009 | $0.00144 |
Grade A, and why
chip-diagram-generator 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 12d 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.

Chip Diagram Generator
任务
为芯片模块架构生成专业、可渲染的图表。
支持的图表类型（按优先级排序）
| 优先级 | 图表类型 | 工具 | 输出格式 | 适用场景 |
|---|---|---|---|---|
| 1（首选） | 框图/架构图/FSM | D2 → PNG | .d2 → d2 --layout dagre |
模块框图、数据通路、状态机、NoC 拓扑 |
| 2 | 时序图 | Wavedrom → PNG | .json → wavedrom-cli |
接口握手、协议事务、关键路径 |
| 3（降级） | 通用图表 | Mermaid | .mmd → mermaid-cli |
仅当 D2 无法表达时使用 |
项目规范：微架构模板 §5.3 明确要求使用 D2 生成 FSM 图。框图和状态机图必须优先使用 D2，Mermaid 仅作为降级方案。
执行步骤
- 确认图表类型与用户所需展示的核心信息。
- 根据图表类型选择工具：
- 框图/FSM → 生成 D2 源码（
.d2文件），使用d2 --layout dagre {file}.d2 {file}.png编译 - 时序图 → 生成 Wavedrom JSON（
.json文件），使用wavedrom-cli -i {file}.json -p {file}.png编译 - 降级 → 仅当 D2/Wavedrom 均无法表达时，使用 Mermaid
- 框图/FSM → 生成 D2 源码（
- 芯片领域模板：
- RR 仲裁器 FSM：S_IDLE → S_CH0/S_CH1/... → S_IDLE，使用独热码编码
- Valid-Ready 握手：valid 不依赖 ready，ready 优先依赖下游
- 子模块框图：左侧 input（箭头→指向模块），右侧 output（箭头→指向外部）
- 编译并验证 PNG 输出成功。为复杂框图添加图例与信号流向说明（箭头旁标注数据宽度）。
输出格式
每个图表输出：
- 源码（D2/Wavedrom JSON）
- 编译命令
- PNG 文件路径
- 简短文字说明图表内容
使用示例
示例 1：生成模块框图（D2）
用户：帮我画 data_adpt 的模块框图，包含 buf、crc、align 三个子模块
预期行为：生成 wd_data_adpt_arch.d2，使用 D2 语法定义子模块节点和信号连线，d2 --layout dagre 编译为 PNG
示例 2：生成握手时序图（Wavedrom）
用户：画一个 valid-ready 握手时序图
预期行为：生成 wd_valid_ready.json，使用 Wavedrom JSON 定义信号时序，wavedrom-cli 编译为 PNG
示例 3：生成 FSM 状态机图（D2）
用户：画一个 4 通道 RR 仲裁器的状态机图
预期行为：生成 wd_rr_arbiter_fsm.d2，使用 D2 语法定义 S_IDLE/S_CH0~S_CH3 状态和转移条件，独热码编码，编译为 PNG
使用示例
示例 1：生成模块框图
用户：帮我画 data_adpt 的模块框图，包含 buf、crc、align 三个子模块
预期行为：生成 Mermaid graph TB 源码，标注信号流向和数据宽度
示例 2：生成握手时序图
用户：画一个 valid-ready 握手时序图
预期行为：生成 Wavedrom JSON 源码，展示 valid/ready/data 信号的时序关系
异常处理
| 场景 | 触发条件 | 处理动作 |
|---|---|---|
| 图表语法错误 | Mermaid/Wavedrom 解析失败 | 标注错误位置，给出修正建议 |
| 图表过于复杂 | 节点数 > 20 | 建议拆分为多个子图 |
| 渲染工具不可用 | mermaid-cli 未安装 | 输出源码，建议用户使用在线编辑器验证 |
| 信号名不规范 | 使用了非法字符 | 自动替换为合法标识符，提示用户确认 |
检查点
检查前：
- 确认图表类型（框图/时序图/FSM）已明确
- 确认核心信息和数据流向已了解
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.
- 12d ago First seen · 111 lines · 88 tokens per session scan A 033337829e04
chip-diagram-generator is a skill published in the GitHub repository zhaixin244-wq/fnw (29 stars, last pushed 3mo ago), licensed MIT. It adds 88 tokens to every session and 1,438 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.
