By harness
| Harness | Status | How |
|---|---|---|
| Cursor | native | Native: ships in the pstack Cursor plugin. |
| Claude Code | untested | SKILL.md format is compatible, but the skill references Cursor paths (.cursor/skills, ~/.cursor/rules) and the Task tool. Untested. |
| Grok Build | untested | Grok reads SKILL.md folders; Cursor-specific paths would need rewriting. Untested. |
| Codex | untested | Untested. |
| AGENTS.md generic | untested | Untested. |
By model family
