You are performing a focused security assessment to find path traversal vulnerabilities in a codebase. This skill uses a three-phase approach with subagents: recon (find file-loading sinks with dynamic paths), batched verify (trace user input and check mitigations in parallel batches of 3), and merge (consolidate batch results into one report).
Sast Pathtraversal is a community-contributed Claude Code skill in the appsec-tools sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/sast-pathtraversal/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when asked to find path traversal, directory traversal, or file disclosure bugs.
The Sast Pathtraversal 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).
mkdir -p ~/.claude/skills/sast-pathtraversal curl -L https://claudskills.com/skills/sast-pathtraversal/SKILL.md \ -o ~/.claude/skills/sast-pathtraversal/SKILL.md
Or just download SKILL.md directly and drop it into ~/.claude/skills/sast-pathtraversal/. Claude Code auto-discovers it on next session.

SKILL.md from the source repository to ~/.claude/skills/sast-pathtraversal/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.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. Sast Pathtraversal is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category.
