dimensional-analysis

separate

Audits code for unit and decimal-scaling bugs and annotates it with dimensional comments recording the units of each value. Use when someone asks to audit or review code for unit confusion, decimals or scaling mismatches, WAD/RAY scale errors, or the wrong token's decimals; to annotate units in a codebase; or to perform a dimensional analysis of a DeFi protocol, offchain code, or other arithmetic-heavy codebase. Catches formulas that combine values carrying different units or scales.

When to use

• Annotating units, dimensions, or decimal scaling in a codebase with numeric arithmetic
• Performing dimensional analysis on DeFi protocols, offchain code, or blockchain-related codebases
• Auditing code for unit/precision bugs
• Documenting existing formulas with their dimensional semantics

When not to use

• Codebases with no numeric arithmetic or unit conversions (e.g., pure CRUD apps, UI code)
• When the user wants a general security audit unrelated to dimensional correctness — use a domain-specific audit skill instead
