Diff two scaffolded harnesses (ADR-031). Reports manifest meta drift + host list + per-file fingerprint changes (added/removed/changed). Exits 0 IDENTICAL, 1 DRIFT, 2 missing manifest. Use --bundle for the ADR-031 schema-1 JSON envelope.
Passed 17 of 18 test cases with the skill, and 6 of 18 without it.

One of 10 test cases the skill fixed. Same model, same prompt, with and without the skill.
What keyword is printed on the final line of human-readable console output when a comparison finds modified files between two harness paths?
| Checked | Without skill | With skill |

The instructions your model reads when the skill loads.
Codex skill: diff two scaffolded harnesses — the ADR-031 Bundle JSON Pattern surfaced through Codex (iter 105 → iter 109).
Two-harness diff. Useful when you've forked an upstream template, when a support ticket says "mine and theirs scaffolded different things", or when a CI script wants a byte-equality check between a candidate scaffold and a known-good baseline.
Reports three sections:
claude-code /
codex / pi-dev / hermes / openclaw / rvm)| Verdict | Exit | Meaning |
|---|---|---|
IDENTICAL | 0 | meta + hosts + every file fingerprint matches |
DRIFT | 1 | at least one of meta / hosts / files differs |
no-manifest-in-a | 2 | a/.harness/manifest.json missing |
no-manifest-in-b | 2 | b/.harness/manifest.json missing |
no-manifest-in-either | 2 | both sides missing manifest |
