Problem:
AI agents (e.g., Claude Code) sometimes use `gh` (GitHub CLI) instead of
`gitlink-cli` when operating on GitLink repositories, causing 'command not
found' errors or targeting the wrong platform.
Solution:
- Add '⛔ Tool Boundary' section to gitlink-shared/SKILL.md with platform-
to-tool mapping table, judgment criteria, and dual-platform guidance
- Add CRITICAL one-liner to all 10 sub-skills ensuring agents see the
constraint even without reading shared
- Does NOT block `gh` for GitHub operations — only prevents misuse on
GitLink resources
Tested with 5 scenarios confirming:
1. GitLink operations correctly use gitlink-cli
2. GitHub operations still use gh when appropriate
3. Ambiguous cases default to gitlink-cli when skill is loaded
