<p>Here is an explicit example of the additional lack of coherence due to LLMs in the Anthropic Claude Code public repo itself: the human maintainer trusts LLM's incorrect understanding of the current state of code in the repo.<p>The comment <a href="https://github.com/anthropics/claude-code/issues/30407#issuecomment-5310485353" rel="nofollow">https://github.com/anthropics/claude-code/issues/30407#issue...</a>, written by Claude Code, and posted by the human GitHub account says:<p>> "Issues here are auto-closed by a bot when they've had no activity for a while and are missing information needed to reproduce (usually a version and steps, or a /feedback ID). Nothing is triaged solely by counting"<p>In reality all issues in this repo are subject to time-based auto-closing, unless they collect a number of upvotes. See details at <a href="https://github.com/anthropics/claude-code/issues/87647" rel="nofollow">https://github.com/anthropics/claude-code/issues/87647</a>.<p>Therefore, I wonder whether the internal review process described in the Anthropic's blog for internal repos also results in such issues, and whether Anthropic has a internal way to measure and mitigate that. The blog post says:<p>> "When someone wants to understand a part of the codebase, they ask Claude to write an explainer for exactly that slice. It takes minutes and reflects the code as it is today."<p>The Claude Code public repo problem shows that LLMs don't always "reflect the code as it is today", and can be a source of additional misunderstanding.</p>

<p>According to the repo maintainer recent comment (generated by Claude Code and posted by a human account) auto-closing of issues that contain reproduction steps should not be happening based on issue inactivity (see <a href="https://github.com/anthropics/claude-code/issues/30407#issuecomment-5310485353" rel="nofollow">https://github.com/anthropics/claude-code/issues/30407#issue...</a>), but it is still hapenning.<p>This has been the state of the repo since around the beginning of 2026.<p>Posting this for visibility here, because the Claude Code repository maintainers are not responsive on GitHub, hoping this will reach someone.<p>There is also a recent change in the Claude Code repo activity where a Claude Code bot triages the issues and labels some of them with "reproduced". This means there is now even a smaller chance to reach any human maintainer if the bot makes a judgment error, like in the auto-closing case described here.</p>

<p>Not anymore. In the years 2012-2017 platforms like coursera or edx provided full courses for free, including graded assignments and exams, teaching assistants hours in the form of discussion forums, and even completion certificates.<p>From around 2017 these platforms started limiting free access, so now in most cases you can only see the lecture materials, with no access to assignments.
From watching alone, learning is incomplete for many people.<p>In addition, many high quality courses (by MIT, Stanford, Berkeley, Caltech, etc.) disappeared from the coursera and edx platforms.</p>

<p>It looks like claude-opus-5, likewise most Anthropic models run in Claude Code, sometimes fails to create a TODO list before jumping in to fix a small bug <a href="https://github.com/marcindulak/claude-fails-to-follow-claude-md/tree/main#example-claude-code-output" rel="nofollow">https://github.com/marcindulak/claude-fails-to-follow-claude...</a>.<p>The desire of the models to act at the cost of ignoring user instructions is still  noticeable.</p>

<p>Claude installer/updater had a high memory usage problem (Gigabytes of resident memory used during a fresh installation of Clade with it's native install.sh script, or during a claude update).

<p>It does not seem they offer a web feed.<p>I asked for Atom/RSS about a year ago <a href="https://github.com/paperswithcode/paperswithcode-data/issues/121" rel="nofollow">https://github.com/paperswithcode/paperswithcode-data/issues...</a>, when the original paperswithcode feed disappeared.<p>It's a kind of coincidence that my own Atom feed of arXiv papers with code went live a few days ago <a href="https://code-available-feed.github.io/code-available-feed/" rel="nofollow">https://code-available-feed.github.io/code-available-feed/</a>.<p>It's independenent from Hugginface, and uses arXiv API directly.
The code is open source, Apache 2. No AI is involved in parsing the arXiv pdfs, only a pattern match for known code-hosting domains like github.com or gitlab.com. This means there false positives, but that's probably fine, and their patterns could be tuned later.<p>You can host your own feed, by forking the repo and setting GitHub Actions environment variables. For now I'm hosting cs.AI and cs.SD categories.</p>

<p>After hearing various similarly sounding opinions about CRUD being easy for LLMs, I started tracking how well LLMs handle a standard CRUD Django app I'm familiar with at <a href="https://github.com/marcindulak/learning-api-styles-gen-ai-experiments" rel="nofollow">https://github.com/marcindulak/learning-api-styles-gen-ai-ex...</a>.<p>So far it appears that LLMs still require constant hand-holding, even for a small educational CRUD app.</p>

<p>The takeaway may be that Anthropic could still profit from selectively labeling the issues as "acknowledged" (suggested in one of the now auto-closed issues <a href="https://github.com/anthropics/claude-code/issues/21732" rel="nofollow">https://github.com/anthropics/claude-code/issues/21732</a>), and preventing them from auto-close.<p>Not all auto-closed issues are slop. A human reviewer can still distinguish them.<p>As for the impact of auto-closing issues, an example of this happened in the period of January/February 2026, when a misconfigured auto-close bot closed over 500 non-slop, human created issues, despite humans still reporting the problems were not fixed <a href="https://github.com/anthropics/claude-code/issues/16497" rel="nofollow">https://github.com/anthropics/claude-code/issues/16497</a>.
It was 30 minutes of daily check by a human to see whether the auto-closed issues were human created or still had humans commenting on them.
Only after over 200 hundred upvotes, the misconfigured bot problem was addressed by Anthropic team by removing the bot, but without reopening any of the incorrectly closed issues.<p>Today it would be probably a half day for a single product manager familiar with the Claude Code product to decide whether any of the daily auto-closed issues are valuable.
There are about 100 issues closed daily by the <a href="https://github.com/anthropics/claude-code/actions/workflows/sweep.yml" rel="nofollow">https://github.com/anthropics/claude-code/actions/workflows/...</a> workflow.<p>Reviewing all issues is probably still valuable for Anthropic, because not all problems are discussed in parallel on social media platforms.</p>
