# jj Guide for AI Agents

Jujutsu (jj) is a Git-compatible VCS with mutable commits, automatic snapshotting, no staging area, and first-class conflicts. This skill teaches you how to use it safely from a non-interactive agent environment.

If `.jj/` exists in the repo root, this is a jj repo. **Use `jj` commands, not `git`.** In a colocated repo (`.jj/` *and* `.git/`), git tools can read the state, but mutations should go through `jj` so the operation log stays consistent.

## Critical Rules

- **NEVER** use interactive flags (`-i`, `--interactive`). TUI prompts hang in agent environments. This applies to `jj split -i`, `jj squash -i`, `jj commit -i`, `jj resolve`, `jj diffedit`, etc.
- **ALWAYS** pass `-m "msg"` when describing/committing. Without `-m`, an editor opens and hangs.
- **VERIFY** mutations with `jj st` and `jj log` after `squash`, `abandon`, `rebase`, `restore`, `commit`. ...

Every non-trivial PR requires an adversarial correctness review before merge.

# jj Guide for AI Agents

Jujutsu (jj) is a Git-compatible VCS with mutable commits, automatic snapshotting, no staging area, and first-class conflicts. This skill teaches you how to use it safely from a non-interactive agent environment.

If `.jj/` exists in the repo root, this is a jj repo. **Use `jj` commands, not `git`.** In a colocated repo (`.jj/` *and* `.git/`), git tools can read the state, but mutations should go through `jj` so the operation log stays consistent.

## Critical Rules

- **NEVER** use interactive flags (`-i`, `--interactive`). TUI prompts hang in agent environments. This applies to `jj split -i`, `jj squash -i`, `jj commit -i`, `jj resolve`, `jj diffedit`, etc.
- **ALWAYS** pass `-m "msg"` when describing/committing. Without `-m`, an editor opens and hangs.
- **VERIFY** mutations with `jj st` and `jj log` after `squash`, `abandon`, `rebase`, `restore`, `commit`. ...

#### Knowledge
- **Fail-first regression proof** (1h ago): For security- or correctness-sensitive pipeline changes, add deterministic regression tests that exercise the real precondition and prove each guard independently. Confirm the test fails on the unfixed code or when the specific guard is removed, then restore the implementation and confirm focused tests pass. Treat skip, early-return, projection, validation, rollback, and redaction guards as high-risk; tests must detect leaked private data, incorrect indices, malformed provider values, or improper failure envelopes. After focused mutation proofs, run the full affected suite, typecheck, lint, formatting, and other repository gates. ...
