+# Squash Merging & PR Size Distribution — Tips from Boris Cherny
+
+A summary of insights shared by Boris Cherny ([@bcherny](https://x.com/bcherny)), creator of Claude Code, on March 25, 2026.
+
+<table width="100%">
+<tr>
+<td><a href="../">← Back to Claude Code Best Practice</a></td>

+</tr>
+</table>
+

+
+## 1/ 266 Contributions in a Single Day — Always Squash
+
+Boris shared his GitHub contribution graph showing **266 contributions on March 24th** — from **141 PRs, always squashed** with a median of **118 lines** per PR.
+
+- Squash merging combines all branch commits into a single commit on the target branch — keeping history clean and linear
+- Each PR = one commit makes it easy to revert entire features and simplifies `git bisect`
+- At high-velocity AI-assisted workflows (141 PRs/day), squash is the pragmatic choice — individual "fix lint", "try this" commits within a branch are noise

+<a href="https://x.com/bcherny/status/2038552880018538749"><img src="assets/boris-25-mar-26/1.png" alt="Boris Cherny — 266 contributions, always squashed" width="50%" /></a>
+
+---
+
+## 2/ PR Size Distribution — Keep PRs Small
+
+Boris shared the size distribution across those 141 PRs, totaling **45,032 lines changed** (additions + deletions):
+
+| Metric | Lines (add+del) | Meaning |
+|--------|---------------:|---------|
+| **p50** | **118** | Median PR size — half of all PRs were 118 lines or fewer |
+| p90 | 498 | 90% of PRs were under 500 lines |
+| **p99** | **2,978** | Only ~1 PR exceeded ~3K lines |
+| min | 2 | Smallest PR — a quick 2-line fix |
+| max | 10,459 | Largest single PR — likely a migration or generated code |
+
+- A **median of 118 lines** means most PRs are focused and reviewable, even at 141 PRs/day
+- The distribution is heavily right-skewed — the occasional large PR is inevitable (bulk renames, migrations), but the norm is tight
+- Small PRs reduce merge conflict risk, are easier to review, and pair perfectly with squash merging for clean reverts
