| Skill | Description |
|
||||
|-------|-------------|
|
||||
| `/simplify` | Review changed files for reuse, quality, and efficiency; spawns 3 parallel review agents |
|
||||
| `/batch <instruction>` | Orchestrate large-scale parallel changes across codebase using git worktrees |
|
||||
| `/debug [description]` | Troubleshoot current session by reading debug log |
|
||||
| `/loop [interval] <prompt>` | Run prompt repeatedly on interval (e.g., `/loop 5m check the deploy`) |
|

|
||||
| `/debug [description]` | Troubleshoot current session by reading debug log |
|
||||
| `/fewer-permission-prompts` | Scan transcripts and propose a prioritized allowlist for common read-only tools |
|
||||
| `/loop [interval] <prompt>` | Run prompt repeatedly on interval (e.g., `/loop 5m check the deploy`) |
|
||||
| `/run` *(v2.1.145+)* | Launch this project's app to see a change running — looks for a project skill, otherwise falls back to built-in patterns per project type |
|
||||
| `/run-skill-generator` *(v2.1.145+)* | Teach `/run`/`/verify` how to handle a specific project by generating a per-project skill |
|
||||
| `/simplify` | Review changed files for reuse, quality, and efficiency; spawns 3 parallel review agents |
|
||||
| `/verify` *(v2.1.145+)* | Build, run, and observe the app to confirm a fix works (not just that tests pass) |
|
||||
|
||||
These skills are available out-of-the-box and do not need to be installed or configured. They follow the same SKILL.md format as custom skills.
