Magic Prompts
Customize the prompt templates, models, and reasoning behind every built-in workflow in Jean.
Every magic command in Jean runs a prompt template.
The Magic Prompts pane lets you replace those templates, pick a different model or backend per workflow, and keep the rest of the flow unchanged.
What is customizable
Each built-in workflow exposes:
- a prompt template
- a backend override
- a model override
- a provider override (for Claude CLI)
- a reasoning or thinking level override
That means you can keep the UI and command flow identical while changing the engine behind any single workflow.
Prompts you can edit
The pane covers the full set of built-in workflows:
Investigation
- Investigate Issue
- Investigate Pull Request
- Investigate Workflow Run
- Investigate Security Alert
- Investigate Advisory
- Investigate Linear Issue
- Handle Review Comments
Git and PR work
- Generate PR Content
- Generate Commit Message
- Code Review
- Resolve Conflicts
- Generate Release Notes
Session management
- Session Naming
- Session Recap
- Context Summary
System prompts
- Global system prompt (appended to every session)
- Parallel execution prompt
Global system prompt
The global system prompt is appended to every session Jean starts.
Use it for:
- house style rules
- required tools or commands
- documentation expectations
- repo-wide conventions
Keep it short. It is added on top of each backend's default system prompt, so long blocks waste tokens on every request.
Per-workflow model choices
A common pattern is to mix models by workflow. For example:
- a lighter model for session naming and commit messages
- a heavier model for code review and PR investigation
- a reasoning-heavy model for conflict resolution
The backend and model dropdowns for each workflow make this easy to set without changing your global defaults.
When to edit a prompt
Edit a prompt when:
- the default output does not match your team's tone
- you want a stricter format for PR titles or commit messages
- a workflow needs extra guardrails (security, licensing, privacy)
- you want an existing workflow to load additional context before answering
Leave the default when the existing output is already close to what you want. The built-in templates are tuned for the current backends.
Reverting
Every customized field can be reset to Jean's default.
If a prompt starts misbehaving after an edit, reverting is the fastest way to confirm the template is the cause.
