What Dimensional Analysis does

Dimensional Analysis annotates codebases with unit and dimension comments, then propagates and validates them to catch formula bugs early. Use when auditing DeFi protocols, blockchain code, or other arithmetic-heavy code.

Dimensional Analysis is cataloged under Quality on DirSkills. Dimensional Analysis comes from a repository tagged agent-skills.

Documentation

README

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 scaling, or precision loss
  • Auditing codebases with mixed decimal precisions or fixed-point arithmetic

This is the opening of the README. Read the full README on GitHub.

Frequently asked about Dimensional Analysis

  • What else does trailofbits publish alongside Dimensional Analysis?

    Dimensional Analysis is one of 25 skills that DirSkills catalogs from trailofbits/skills, the repository it ships in. Its siblings there include Agentic Actions Auditor, Algorand Vulnerability Scanner and Audit Context Building. Each one is a separate skill with its own page in this directory, installs the same way Dimensional Analysis does, and is maintained by trailofbits in that same repository. The rest of the collection is listed on the trailofbits/skills page.

  • How does Dimensional Analysis compare to other Quality skills?

    Dimensional Analysis ranks #253 by stars among the 1354 Quality skills in this catalog. The most-starred ones next to it are Benchmark, Benchmark Optimization Loop and API Design Patterns. DirSkills ranks by the star count of the repository each skill ships in, so that order reflects how popular those repositories are rather than any review of Dimensional Analysis against them. Open each page to compare what they document and how they install.

Audit Context Building

Audit Context Building analyzes an unfamiliar codebase to map functions, assumptions, guarantees, and dependencies before any vulnerability hunting. Use it at the start of an audit, threat model, or architecture review to produce dossiers and open questions that feed later phases.
