Automatically instruments source code to collect runtime information such as function calls, branch decisions, variable values, and execution traces while preserving original program semantics. Use when users need to: (1) Add logging or tracing to code for debugging, (2) Collect runtime execution data for analysis, (3) Monitor function calls and control flow, (4) Track variable values during execution, (5) Generate execution traces for testing or profiling. Supports Python, Java, JavaScript, and C/C++ with configurable instrumentation levels.

JeecgBoot Online表单（cgform）全生命周期管理——通过API自动创建/编辑数据库表和表单配置， 支持单表、主子表、树表，26种控件类型，以及JS/Java/SQL增强、权限配置、数据CRUD、积木报表集成。 只要用户意图涉及「Online表单」就必须使用本技能，包括但不限于： 创建或配置数据库表（"建一张请假表"、"创建online表"、"做一个带下拉选择的表"、"低代码表单"、"在线表单"、"配置表"）、 修改已有Online表字段（"加个字段"、"改字段类型"、"加子表"、"删除字段"）、 配置表单增强（"JS增强"、"自定义按钮"、"表单联动"、"Java增强"、"SQL增强"）、 配置权限（"字段权限"、"按钮权限"、"数据权限"、"授权给角色"）、 管理表单数据（"插入数据"、"查询记录"、"导出CSV"、"造测试数据"）、 以及关联积木报表（"给这个表加报表"、"集成打印"）。 即使用户只描述了业务需求而没说"online"（如"做一个员工信息管理功能，包含姓名、部门下拉、入职日期"）， 只要涉及元数据驱动的表单配置，也应触发本技能。 注意：不要与「设计器表单」(desform)混淆——desform是拖拽式表单设计器，用skill jeecg-desform处理； 也不要与「Online报表」(cgreport)或「Online图表」(onlchart)混淆——它们是SQL驱动的只读展示。

Vulnerability audit and dataflow analysis built on the neug CPG engine. file_audit (default, recommended): first builds a function-level summary graph (tier1) over the entire project, then incrementally builds detailed CPGs (tier2) on demand for chosen functions; both tiers coexist in a single neug database (unified schema, cross-layer refines edges; C/Java/Python/Rust). All capabilities are exposed as CLI tool subcommands (audit/overview/build/query/methods/paths), so an agent can drive the audit step by step via shell; the audit subcommand can also run the built-in LLM loop. The same tooling also supports a dataflow analysis mode (Workflow C): no vulnerability hunting, only variable-level dataflow tracing for functions of interest, producing dataflow_analysis.json. repo_audit: multi-round LLM/Cypher audit over a full-repo CPG. Use when the user asks to audit a codebase/project for vulnerabilities, scan a project with CPG/neug, run repo_audit/file_audit, find source-to-sink taint paths, or analyze dataflow inside a function. Supports C, Java, Python, and Rust.

ESLint is the standard linting tool for JavaScript and TypeScript projects. It statically analyzes your code to find problems, enforce coding conventions, and catch bugs before they reach production. ESLint 9 introduced the flat config format, replacing the legacy `.eslintrc` system with a simpler, more composable `eslint.config.js` file. With a rich plugin ecosystem covering React, TypeScript, accessibility, and import ordering, ESLint is the backbone of code quality in modern web development.
