A secret leaks through source, git history, logs, error pages, URLs, client bundles, image layers, CI output, and your own context window. The job is to reference secrets by name only, inject them at runtime from the environment or a secret manager, keep them out of every output channel, and make rotation possible without downtime (OWASP Secrets Management Cheat Sheet; ASVS 5.0 V13.3 and 14.2.1).
Security Secret Handling 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/security-secret-handling/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when a ticket involves secrets — API keys, tokens, passwords, connection strings, signing keys — or their configuration, storage, logging, or rotation. Invoke for "wire up the API key", "load config from the environment", "stop logging the token", or when adding any integration that needs a credential.
The Security Secret Handling 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 213,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
