> Turns ambiguous requirements into an ordered, reviewable implementation plan.

**Planner** does the thinking before any code changes — especially on large, complex, or
multi-file tasks.

## What it produces

* **Requirements analysis**: edge cases, dependency requirements, and potential breaking changes.
* **Schema modelling**: normalised relational designs (Postgres, SQLite) with foreign keys and indexes.
* **Implementation roadmap**: an ordered checklist stating which files to create or update.

## How it protects your codebase

Planner works in an advisory capacity. It does not run destructive commands or make unreviewed
file edits — [Bhai](/agents/bhai) applies the plan, step by step, through the normal approval
and diff flow.

<Tip title="Ask for a plan first">On a large change, start with "plan this before coding". You get the checklist to review
up front, then hand it back to Bhai to execute.</Tip>
