+# Graphite PR Workflow Rules
+
+## Single PR per Spec / Feature
+
+When working on a spec or feature, **never create additional branches or PRs without explicit user instruction**.
+
+- Do NOT use `gt create` to add commits to an existing branch — `gt create` ALWAYS creates a new branch
+- All incremental changes (spec updates, fixes, additions) go into the **existing branch** via `gt modify` (`gt m`)
+- If the current branch already has a PR open, use `gt modify` to amend — do not create a sibling or child branch
+
+## Correct Flow for Updating an Existing PR
+
+```bash
+# Stage changes
+git add <files>
+
+# Amend the current branch's commit (gt m = gt modify)
+gt modify --commit -m "feat(ISSUE): update description"
+# or: gt m --commit -m "feat(ISSUE): update description"
+
+# Push to update the existing PR
+gt submit --no-interactive --publish
+```
+
+## Wrong Flow (Do NOT do this)
+
+```bash
+# ❌ ALWAYS creates a new branch — never use this to update an existing PR
+gt create -m "some update"   # creates a new branch + new PR automatically
+gt submit                    # results in a new unwanted PR
+```
+
+## Why
+
+`gt create` unconditionally creates a new branch and commit on top of the current stack.
+`gt modify` (alias `gt m`) amends the **current** branch's tip commit in place.
+
+Using `gt create` to update an existing PR creates extra branches and PRs, clutters the PR list, and requires manual cleanup (fold, close, comment). One spec = one PR.
