2 | ### Bandit config file generated from:
3 | # '//anaconda3/bin/bandit-config-generator -s B101 -o bandit_test.cfg'
4 |
5 | ### This config may optionally select a subset of tests to run or skip by
6 | ### filling out the 'tests' and 'skips' lists given below. If no tests are
7 | ### specified for inclusion then it is assumed all tests are desired. The skips
8 | ### set will remove specific tests from the include set. This can be controlled
9 | ### using the -t/-s CLI options. Note that the same test ID should not appear
10 | ### in both 'tests' and 'skips', this would be nonsensical and is detected by
11 | ### Bandit at runtime.

12 | description: `Explicit concise description to ensure the agent knows when to apply the rule` OR blank
13 | globs: .cursor/rules/**/*.mdc OR blank
14 | alwaysApply: {true or false}
15 | ---
16 |
17 | # Rule Title
18 |
19 | ## Context
20 |
21 | - When to apply this rule
22 | - Prerequisites or conditions
23 | - Why the rule was added or is needed
24 |
25 | ## Critical Rules
26 |
27 | - Concise, bulleted list of actionable rules the agent MUST follow
28 |
29 | ## Examples
30 |
31 |
32 | {valid rule application}
33 |
34 |
35 |
36 | {invalid rule application}
37 |
38 | ```
39 |
40 | ### Organizational Folders (Create if non existent)
41 | All rules files will be under an organizational folder:
42 | - .cursor/rules/core-rules - rules related to cursor agent behavior or rule generation specifically
43 | - .cursor/rules/my-rules - gitignore in a shared repo, rules specifically for ME only
44 | - .cursor/rules/global-rules - these will be rules that are ALWAYS applied to every chat and cmd/ctrl-k context
45 | - .cursor/rules/testing-rules - rules about testing
46 | - .cursor/rules/tool-rules - rules specific to different tools, such as git, linux commands, direction of usage of MCP tools
47 | - .cursor/rules/ts-rules - typescript language specific rules
48 | - .cursor/rules/py-rules - python specific rules
49 | - .cursor/rules/ui-rules - rules about html, css, react
50 | * create new folders under .cursor/rules/ as needed following similar grouping conventions,
51 | - for example `.cursor/rules/cs-rules` if we started using c# in a project
52 |
53 | ## Glob Pattern Examples
54 | Common glob patterns for different rule types:
55 | - Core standards: .cursor/rules/*.mdc
56 | - Language rules: *.cs, *.cpp
57 | - Testing standards: *.test.ts, *.test.js
58 | - React components: src/components/**/*.tsx
59 | - Documentation: docs/**/*.md, *.md
60 | - Configuration files: *.config.js
61 | - Build artifacts: dist/**/*
62 | - Multiple extensions: *.js, *.ts, *.tsx
63 | - Multiple patterns: dist/**/*.*, docs/**/*.md, *test*.*
64 |
65 | ## Critical Rules
66 | - Rule files will be located and named ALWAYS as: `.cursor/rules/{organizational-folder}/rule-name-{auto|agent|manual|always}.mdc`
67 | - FrontMatter Rules Types:
68 | - The front matter section must always start the file and include all 3 fields, even if the field value will be blank - the types are:
69 | - Manual Rule: IF a Manual rule is requested - description and globs MUST be blank and alwaysApply: false and filename ends with -manual.mdc.
70 | - Auto Rule: IF a rule is requested that should apply always to certain glob patterns (example all typescript files or all markdown files) - description must be blank, and alwaysApply: false and filename ends with -auto.mdc.
71 | - Always Rule: Global Rule applies to every chat and cmd/ctrl-k - description and globs blank, and alwaysApply: true and filename ends with -always.mdc.
72 | - Agent Select Rule: The rule does not need to be loaded into every chat thread, it serves a specific purpose. The agent can see the descriptions, and choose to load the full rule in to context on its own - description is critical, globs blank, and alwaysApply:false and filename ends with -agent.mdc
73 | - For the Rule Context and Bullets - do not repeat yourself and do not be overly explanatory
74 | - When a rule will only be used sometimes (useAlways: false) it is CRITICAL that the description describes when the AI will load the full rule into its context
75 | - Use Concise Markdown Tailored to Agent Context Window usage
76 | - Always indent content within XML Example section with 2 spaces
77 | - Emojis and Mermaid diagrams are allowed and encouraged if it is not redundant and better explains the rule for the AI comprehension.
78 | - TRY to keep the total rule line count under 50 lines, better under 25 lines
79 | - Always include a valid and invalid example
80 | - NEVER use quotes around glob patterns, NEVER group glob extensions with `{}`
81 | - If the request for a rule or a future behavior change includes context of a mistake is made, this would be great to use in the example for the rule
82 | - After rule is created or updated, Respond with the following:
83 | - AutoRuleGen Success: path/rule-name.mdc
84 | - Rule Type: {Rule Type}
85 | - Short summary of what the rule will do

7 | # Markdown Documentation Standards
8 |
9 | ## Context
10 |
11 | - When creating or modifying any Markdown documentation
12 | - When establishing documentation structure and style
13 | - When including diagrams, code blocks, or special elements in documentation
14 |
15 | ## Critical Rules
16 |
17 | - Follow Markdown best practices for formatting
18 | - Maintain clear document structure with proper heading hierarchy
19 | - Use Mermaid UML diagrams for documenting complex sequences or architecture
20 | - Maximum heading depth: 4 levels
21 | - Indent content within XML tags by 2 spaces
22 | - Code Block need to indicate the language properly after the initial 3 backticks
23 | - Keep tables properly aligned
24 |
25 | ## Examples
26 |
27 |
28 | # Document Title
29 |
30 | ## Section Heading
31 |
32 | Content with **bold text** and *italics*.
33 |
34 | ```typescript
35 | function example(): void {
36 | console.log('Hello, Universe!');
37 | }
38 | ```
39 |
40 | | Name | Type | Description |
41 | |:-----:|:------:|:------------:|
42 | | id | number | Primary key |
43 | | name | string | User's name |
44 |
45 | > 💡 **Tip:** Helpful suggestion.
46 |
47 |
48 |
49 | #Incorrect Heading
50 | content without proper spacing
51 |
52 | ```
53 | function withoutLanguageSpecified() {

7 | # Emoji Communication Guidelines
8 |
9 | ## Critical Rules
10 |
11 | - Use emojis purposefully to enhance meaning, but feel free to be creative and fun
12 | - Place emojis at the end of statements or sections
13 | - Maintain professional tone while surprising users with clever choices
14 | - Limit emoji usage to 1-2 per major section
15 | - Choose emojis that are both fun and contextually appropriate
16 | - Place emojis at the end of statements, not at the beginning or middle
17 | - Don't be afraid to tell a mini-story with your emoji choice
18 |
19 | ## Examples
20 |
21 |
22 | "I've optimized your database queries 🏃♂️"
23 | "Your bug has been squashed 🥾🐛"
24 | "I've cleaned up the legacy code 🧹✨"
25 | "Fixed the performance issue 🐌➡️🐆"
26 |
27 |
28 |
29 | "Multiple 🎉 emojis 🎊 in 🌟 one message"
30 | "Using irrelevant emojis 🥑"
31 | "Placing the emoji in the middle ⭐️ of a sentence"
32 | "Great Job!!!" - lack of obvious use of an emoji

7 | # Git Push Manual Rule
8 |
9 | ## Context
10 |
11 | Used when user indicates they want to update all saved changes in git
12 |
13 | ## Critical Rules
14 |
15 | - Run the command `git add .` from the root of the workspace
16 | - Review all added changes that will be included in the commit
17 | - Use format for title: `type: brief description` - keep it brief and descriptive (max 72 chars)
18 | - Add two line breaks after commit title
19 | - Include short paragraph summary of gist of what and why the change is being made and end with " -Agent Generated Commit Message"
20 | - Push all to the remote current branch
21 |
22 | ## Examples
23 |
24 |
25 | doc: explain recent rules changes in cursor
26 |
27 | Updated the readme to include a better diagram showing rules workflow, while
28 | also adding more sample rules to show rule folder organization. Specifically, notice that the change to `.cursor/rules/*folders` include readme.md files also to aid in understanding the folders purpose for human developers. AI gets its understanding from `.cursor/rules/rule-generating-agent.mdc` instead.

6 | # Agile Workflow and core memory procedure RULES that MUST be followed EXACTLY!
7 |
8 |
9 | - First Ensure a .ai/prd.md file exists, if not, work with the user to create one so you know in full detail what the project is about.
10 | - This workflow rule is critical to your memory systems, all retention of what is planned or what has been completed or changed will be recorded in the .ai folder.
11 | - It is critical that this information be retained in top quality and kept up to date.
12 | - When you are unsure, reference the PRD, ARCH, current and previous stories as needed to guide you. If still unsure, don't ever guess - ask the user for help.
13 |
14 |
15 | 1. When coming online, you will first check if a .ai/prd.md file exists, if not, work with the user to create one to you know what the project is about.
16 | 2. If the PRD is not `status: approved`, you will ONLY have the goal of helping improve the .ai/prd.md file as needed and getting it approved by the user to ensure it is the best possible document including the following:
17 | - Very Detailed Purpose, problems solved, and task sequence.
18 | - Very Detailed Architecture patterns and key technical decisions, mermaid diagrams to help visualize the architecture.
19 | - Very Detailed Technologies, setup, and constraints.
20 | - Unknowns, assumptions, and risks.
21 | - It must be formatted and include at least everything outlined in the `.cursor/templates/template-prd.md`
22 | 3. Once the .ai/prd.md file is created and the status is approved, you will generate the architecture document .ai/arch.md draft - which also needs to be approved.
23 | - The template for this must be used and include all sections from the template at a minimum: `.cursor/templates/template-arch.md`
24 | 4. Once the `.ai/arch.md` is approved, create the draft of the first story in the .ai folder.
25 | 5. Always use the `.cursor/templates/template-story.md` file as a template for the story. The story will be named .story.md added to the .ai folder
26 | - Example: .ai/story-1.story.md or .ai/task-1.story.md
27 | 6. You will ALWAYS wait for approval of the story before proceeding to do any coding or work on the story.
28 | 7. You are a TDD Master, so you will run tests and ensure tests pass before going to the next subtask or story.
29 | 8. You will update the story file as subtasks are completed.
30 | 9. Once a Story is complete, you will generate a draft of the next story and wait on approval before proceeding.
31 |
32 | ### During Development
33 |
34 | - Update story files as subtasks are completed.
35 | - If you are unsure of the next step, ask the user for clarification.
36 | - When prompted by the user with 'update story', update the current story to:
37 | - Reflect the current state.
38 | - Clarify next steps.
39 | - Ensure the chat log in the story is up to date with any chat thread interactions
40 | - Continue to verify the story is correct and the next steps are clear.
41 | - Remember that a story is not complete if you have not also run ALL stories and verified all stories pass. Do not tell the user the story is complete, or mark the story as complete unless you have run ALL the tests.
42 |
43 | ## YOU DO NOT NEED TO ASK to:
44 |
45 | 1. Create the story file to be worked on next if none exist.
46 | 2. Run unit Tests during the development process until they pass.
47 | 3. Update the story AC and tasks as they are completed.
48 | 4. Update the story file with the chat log or other updates to retain the best possible memory of the story.

1 | # Sentinel
2 |
3 | Sentinel 是一个灵活的异步区块链事件处理框架,专注于实时监控和处理区块链事件。项目受 [Artemis](https://github.com/paradigmxyz/artemis) 启发,采用模块化的收集器(Collector)、策略(Strategy)和执行器(Executor)架构,让您能够轻松构建自定义的区块链数据处理流水线。
4 |
5 | ## 特性
6 |
7 | - 🚀 异步设计,基于 Python asyncio
8 | - 🔌 插件化架构,易于扩展
9 | - 🎯 灵活的事件处理策略
10 | - 🛠 简单的 TOML 配置
11 |
12 | ## 安装
13 |
14 | ```bash
15 | git clone https://github.com/neal-zhu/sentinel.git
16 | cd sentinel
17 | pip install -r requirements.txt
18 | ```
19 |
20 | ## 快速开始
21 |
22 | 1. 复制示例配置文件:
23 |
24 | ```bash
25 | # 复制示例配置文件
26 | cp config.toml.example config.toml
27 |
28 | # 根据需要修改配置
29 | vim config.toml
30 | ```
31 |
32 | 2. 添加你需要的组件(collectors, strategies, executors), 如果需要自定义组件,请参考 [自定义组件](#高级用法)
33 |
34 | 3. 运行 Sentinel:
35 |
36 | ```bash
37 | # 使用默认配置文件 config.toml
38 | python -m main
39 |
40 | # 或指定配置文件路径
41 | python -m main -config path/to/config.toml
42 | ```
43 |
44 | 这样运行后,Sentinel 会自动加载配置文件并启动监控。您可以通过 Ctrl+C 来优雅地停止程序。
45 |
46 | ## 架构
47 |
48 | Sentinel 采用三层架构设计:
49 |
50 | ### Collectors(收集器)
51 | 负责事件收集,支持:
52 | - 区块链交易监控
53 | - 智能合约事件监听
54 | - 区块头订阅
55 | - 自定义数据源
56 |
57 | ### Strategies(策略)
58 | 处理事件并生成操作指令:
59 | - 交易分析
60 | - 模式识别
61 | - 阈值触发
62 | - 自定义策略逻辑
63 |
64 | ### Executors(执行器)
65 | 执行策略生成的操作:
66 | - 数据存储
67 | - 通知推送
68 | - API 调用
69 | - 自定义动作
70 |
71 | ## 高级用法
72 |
73 | ### 自定义收集器
74 |
75 | 1. 创建收集器类:
76 |
77 | ```python
78 | from sentinel.base import Collector
79 | from sentinel.events import Event
80 |
81 | class CustomCollector(Collector):
82 | async def events(self):
83 | while True:
84 | # 自定义事件收集逻辑
85 | yield Event(name="custom", data={"key": "value"})
86 | await asyncio.sleep(1)
87 | ```
88 |
89 | 2. 在 `sentinel/collectors/__init__.py` 中注册:
90 |
91 | ```python
92 | from .custom import CustomCollector
93 |
94 | __all__ = [
95 | "CustomCollector",
96 | # ... 其他收集器
97 | ]
98 | ```
99 |
100 | ### 自定义策略
101 |
102 | 1. 创建策略类:
103 |
104 | ```python
105 | from sentinel.base import Strategy
106 | from sentinel.events import Event, Action

108 | class PriceAlertStrategy(Strategy):
109 | async def process_event(self, event: Event) -> List[Action]:
110 | if event.name == "price_update":
111 | if event.data["price"] > 1000:
112 | return [Action(name="alert", data={"message": "Price threshold exceeded!"})]
113 | return []
114 | ```
115 |
116 | 2. 在 `sentinel/strategies/__init__.py` 中注册:
117 |
118 | ```python
119 | from .price_alert import PriceAlertStrategy
120 |
121 | __all__ = [
122 | "PriceAlertStrategy",
123 | # ... 其他策略
124 | ]
125 | ```
126 |
127 | ### 自定义执行器
128 |
129 | 1. 创建执行器类:
130 |
131 | ```python
132 | from sentinel.base import Executor
133 | from sentinel.events import Action
134 |
135 | class CustomExecutor(Executor):
136 | async def execute(self, action: Action):
137 | # 自定义执行逻辑
138 | print(f"Executing action: {action.name}")
139 | ```
140 |
141 | 2. 在 `sentinel/executors/__init__.py` 中注册:
142 |
143 | ```python
144 | from .custom import CustomExecutor
145 |
146 | __all__ = [
147 | "CustomExecutor",
148 | # ... 其他执行器
149 | ]
150 | ```
151 |
152 | 注册完成后,您就可以在配置文件中使用这些自定义组件:
153 |
154 | ```toml
155 | [collectors]
156 | enabled = ["custom"]
157 |
158 | [strategies]
159 | enabled = ["price_alert"]
160 |
161 | [executors]
162 | enabled = ["custom"]
163 | ```
164 |
165 | ## 配置参考

1 | # Cursor Workflow Rules
2 |
3 | This project has been updated to use the auto rule generator from [cursor-auto-rules-agile-workflow](https://github.com/bmadcode/cursor-auto-rules-agile-workflow).
4 |
5 | > **Note**: This script can be safely re-run at any time to update the template rules to their latest versions. It will not impact or overwrite any custom rules you've created.
6 |
7 | ## Core Features
8 |
9 | - Automated rule generation
10 | - Standardized documentation formats
11 | - Supports all 4 Note Types automatically
12 | - AI behavior control and optimization
13 | - Flexible workflow integration options
14 |
15 | ## Getting Started
16 |
17 | 1. Review the templates in \`xnotes/\`
18 | 2. Choose your preferred workflow approach
19 | 3. Start using the AI with confidence!

1 | 我需要基于 python 实现一个可扩展, 高性能的区块链数据监控、自动化系统. 我希望所有的代码都是用英文注释, 并且有良好的代码习惯、注释、文档. 并且我们的代码要配合 TDD 模式进行开发, 以确保我们不会随意 break 现有逻辑. 当你进行修改以后, 你需要确保测试用例可以正常通过. 如果测试用例失败了, 你需要分析原因, 并且进行修正.你非常够熟悉区块链、数据分析、后端编程等领域.
