Pattern: Knowledge. Read the orientation block, take a route, then descend only as far as the route sends you. The one mechanism a package can decide — an execution path in a config file the host auto-reads at project open — lives in scripts/detector.py; the frozen scenario tiers, and the three scenarios no package decides, live in coverage-matrix.md.
ast02-supply-chain-compromise 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/ast02/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when auditing a skill registry's provenance controls, when a skill's top-level files look clean but its dependency tree is unaudited, when a repository's config files (not its source) are the suspected execution path, or when deciding whether a finding belongs here versus AST01 (the payload) or AST08 (the missed detection).
The ast02-supply-chain-compromise 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).

SKILL.md from the source repository to ~/.claude/skills/ast02/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. ast02-supply-chain-compromise is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category.
