This skill packages the method that produced the GT-KB self-investigation finding corpus (HYG-001..068, frozen in config/governance/hygiene-baseline-registry.toml). It is the orchestration half of the layered repeatable-investigation design chartered by DELIB-FABLE-GRILL-20260610-Q5: a deterministic detector core (FAB-19, separate thread) feeds a reusable orchestration skill (this skill), and a future delta mode keys re-runs to the baseline registry.
Gtkb Hygiene Investigation is a community-contributed Claude Code skill in the scaffolders sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/gtkb-hygiene-investigation/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when the owner asks for a hygiene/architecture investigation, a drift/debt census, or a repeat of the GT-KB self-investigation that produced HYG-001.
The Gtkb Hygiene Investigation Claude Code skill is built for developers, power users, and teams automating repetitive workflows and improving developer experience. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 146,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
