Subject: [PATCH] fix(skills): anchor guard/freeze/careful hook paths so they
 survive CC 2.1.162 (#1871)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The PreToolUse frontmatter hooks for guard, freeze, and careful invoked
`bash ${CLAUDE_SKILL_DIR}/.../check-*.sh`. Claude Code 2.1.162 no longer populates
${CLAUDE_SKILL_DIR} in the skill-hook execution env, so it expanded to empty and
every Edit/Write/Bash ran `bash /...` and errored — breaking the safety skills
entirely.

Frontmatter hooks run before any skill-body bash, so no runtime-resolved variable
can fix this; the command must be a path that's valid at hook time. Anchor to the
installed checkout: $HOME/.claude/skills/gstack/{careful,freeze}/bin/check-*.sh,
where the scripts actually live. ($HOME is expanded by the hook shell.)

Reported by @omariani-howdy. Regenerated the three SKILL.md from templates.
