Blast radius (pstack)
Find what a change breaks beyond the diff, then prove the one fact its safety depends on by running real code. Uses an explicit 5-level evidence ladder from 'you said so' to 'reproduced in the running app'.

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
| Claude | default reviewer/worker model (claude-opus-5-5) via setup-pstack |
| GPT | untested |
| Grok | default second model (grok-4.7) via setup-pstack |
