▸ 精选理由

对涉及货币、物理量或 DeFi 计算的代码尤为有用，减少单位错误与漏洞。

这个 Skill 做什么

为代码库标注单位与量纲，发现混用精度与缩放导致的计算或安全问题。

在代码里标注单位与量纲（比如金额精度、时间单位、缩放因子），帮你发现混用单位或精度导致的计算错误或安全漏洞。常用在 DeFi、链下计算或任何大量数值运算的代码库审查时。特点是把单位作为注释和传播规则，及早抓住维度不匹配和公式错误，避免线上损失。

Annotates codebases with dimensional analysis comments documenting units, dimensions, and decimal scaling. Use when someone asks to annotate units in a codebase, perform a dimensional analysis, or find vulnerabilities in a DeFi protocol, offchain code, or other blockchain-related codebase with arithmetic. Prevents dimensional mismatches and catches formula bugs early.

# Dimensional Analysis Skill

This skill orchestrates a dimensional-analysis pipeline for codebases that perform numeric computations with mixed units, precisions, or scaling factors. The main skill context is a workflow controller only: it delegates scanning, vocabulary discovery, annotation, propagation, and validation to specialized subagents, then manages batching, persistence, retries, coverage gates, and final reporting.

## When to Use

- Annotating a codebase with unit/dimension comments (e.g., `D18{tok}`, `D27{UoA/tok}`)
- Performing dimensional analysis on DeFi protocols, financial code, or scientific computations
- Hunting for arithmetic bugs caused by unit mismatches, missing sca
