# GitHub Copilot coding agent

16 Hacker News commenters recommended GitHub Copilot coding agent and 36 criticized it, November 2025 to November 2026. It was recommended in 8 of 13 months.

**Verdict:** People recommend it for running coding tasks in an isolated container and reviewing results in one PR. Main caveat: critics say it changes silently and edits PRs unprompted.

## Why people recommend it

- Gets most changes right (2 comments): "it's kind of wild seeing how diligent it is even with the most trivial of changes" ([source](https://news.ycombinator.com/item?id=46916108)) "I'd say it gets them right the vast majority of the time now." ([source](https://news.ycombinator.com/item?id=46519888))
- Less setup than alternatives (2 comments): "Copilot Agent and Claude Code use their own sandbox, which requires less setup but is also quite limited" ([source](https://news.ycombinator.com/item?id=46494574)) "Jules and GitHub Copilot Agent suffice for similar workflows with less setup." ([source](https://news.ycombinator.com/item?id=46494530))

## What people warn about

- Inserts unrelated content into PRs (5 comments): "No one, anywhere, ever wants this or anything like it. Do not inject anything that is outside of the context of the session, ever." ([source](https://news.ycombinator.com/item?id=47575471)) "irrelevant modification of the PR description to insert unrelated content is specifically egregious" ([source](https://news.ycombinator.com/item?id=47573399)) "It literally went in and edited the PR description 8 minutes after the user submitted it." ([source](https://news.ycombinator.com/item?id=47584827))
- Changes behavior without announcement (2 comments): "it seems like almost every other week they silently change something with zero public announcement that creates real disruption for our team" ([source](https://news.ycombinator.com/item?id=49384294)) "they silently change something with zero public announcement or documentation" ([source](https://news.ycombinator.com/item?id=49878406))
- Wrong fixes and hallucinated issues (3 comments): "The copilot agent then implemented that by adding a replace statement, which is not how you are supposed to do this." ([source](https://news.ycombinator.com/item?id=46936733)) "this actually doesn't work, even though the documentation makes it seem like it should." ([source](https://news.ycombinator.com/item?id=46944725)) "it caught GitHub's own copilot-swe-agent hallucinating a fake RCE vulnerability" ([source](https://news.ycombinator.com/item?id=47242860))
- Limited sandbox and slow (2 comments): "Copilot Agent and Claude Code use their own sandbox, which requires less setup but is also quite limited" ([source](https://news.ycombinator.com/item?id=46494574)) "I found that to be slow compared to natively running copilot in the IDE." ([source](https://news.ycombinator.com/item?id=46418656))
