Pattern: Knowledge. The decision rule this category turns on: a version string is an attacker-controlled claim, not a security property — "v1.0.1" looks like a patch and can just as easily carry a new payload, because nothing about a semver bump is cryptographically meaningful on its own. scripts/ ships no detector for this category and the section below explains why that is the finished state; frozen scenario tiers live in coverage-matrix.md.
ast07-update-drift is a community-contributed Claude Code skill in the web-security sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/ast07/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when auditing an installed skill's pin discipline (hash vs. version range), when an update mechanism applies upstream changes without human review, when a downgrade needs distinguishing from a legitimate version bump, or when deciding whether Rollback Attack / Hot-Reload Abuse are checkable from this artifact at all.
The ast07-update-drift 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 196,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

SKILL.md from the source repository to ~/.claude/skills/ast07/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).
