From the source SKILL.md

Trace how data moves through the application from input to storage to output. Identify trust boundary crossings, encryption/decryption points, serialization steps, and data transformation operations. Produces annotated data flow maps with security observations at each transition.

What this skill does

Data Flows is a community-contributed Claude Code skill in the security-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/data-flows/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Data Flows Claude Code skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 153,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

When should I use the Data Flows skill?
Use Data Flows when your Claude Code task falls under the Security category — specifically in the security misc area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Data Flows" or describe the task and let Claude pick). Browse related skills at /category/security/.
What is a Claude Code skill and how does the Data Flows skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Data Flows is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category.
