How To Write With An LLM

Rule Number One: You may not use a single word an LLM suggests to you.

[...] I think that as a form of intellectual personal protective equipment you should adopt the rule that any specific turn of phrase an LLM suggests is off limits. Be strict about the rule!

I won't let LLMs write content for my blog, but I use them for fact-checking, spelling and grammar and as an occasional thesaurus (see my proofreading prompt).

The rule to never use a turn of phrase suggested by an LLM feels good to me. The text has that weird smell to it, and it's also a good principle to help stay disciplined.

Later in this piece Thomas shows a screenshot of his personal LLM copyediting tool (see also this Twitter thread), and provides a prompt to help kickstart building your own.

Release: datasette 1.0a40

Same security fix as 0.65.5, plus some neat new features and bug fixes:

• Plugins can now launch and manage background tasks using the new datasette.add_background_task() method. Thanks, Alex Garcia.
• I've migrated Datasette to httpx2 for features like the internal datasette.client.get() method.
• A whole lot of bug fixes, many of them stemming from a recent effort to triage issues for a 1.0 stable release.

The contagion of fear

Bryan shares a story of his own youthful mistakes causing unjustified panic among less technical peers, and warns against doing the same:

These ghoulish claims strike brazenly at the hearth, and given the obvious importance of AI, it is unsurprising that they have leapt into the mainstream, with people asking the natural question: how would that happen? The answers always rely on hand-wavy extrapolation into the future; for example, Jacob Coxon cites "hacking critical infrastructure" and "extinction-level bioweapons" without further elaboration. But Coxon is not an expert on critical infrastructure, nor on bioweapons — nor, for that matter, on extinction. [...]

That said, we should not expect the public to understand LLMs, critical infrastructure, bioweapons, extinction biology, etc. — that burden must lie with those making the claim. The lesson that I learned (shamefully) decades ago is that domain experts, by way of their expertise, implicitly hold the public’s trust — and we must not abuse it. It is incumbent upon us to be circumspect in our claims — and maximally so when raising the alarm.

Bryan talked about his doubts about the bioweapons concerns in the recent episode of Oxide and Friends that I joined. You can hear more of his thoughts on that starting at 51m44s in that episode. Here's 57m04s:

I really think we need to be careful because it's so easy to be overcome with fear when we kind of make up these... it can give you biological weapons. Like, how? I mean, can we please have a biologist weigh in on this? Or can we have like someone who's got experience with bioweapons? [...] The bioweapon thing just gets under my fingernails because it leaves so much to the imagination that we insert with fear.

My comment on What blog posts influenced your thinking the most? — Lobste.rs.

An early Joel Spolsky one for me was The Law of Leaky Abstractions. I read that near the start of my career and it's encouraged me to always be looking for improved understanding of the layers under where I'm working, just in case one of those abstractions leaks.

A more recent one, from 2018, is Migrations: the sole scalable fix to tech debt by Will Larson. I absolutely love his idea that migrations (e.g. replacing one service with a new one, or switching database engines, or whatever) are part and parcel of software engineering and are a skill that you should invest in and get good at, not avoid or treat as special one-offs.

The Engineer/Manager Pendulum by Charity Majors was hugely influential for me. I was stuck in engineering management and worried that if I switched back to being an "Individual Contributor" (ugh I hate that term) I'd damage my career. Charity gave me permission to make the switch by pointing out that many of the most successful software developers pendulum from one track to the other multiple times over their career, and doing so makes you better at both sides.

Here's a neat thing I had ChatGPT Work with GPT-6 Astra (Max) do this morning:

I live at <my address>. Figure out 5K and 10K running routes from me that loop from my house. Use OSM data.

It worked for 27 minutes and produced exactly what I'd asked for, as both an embedded visualization and downloadable GPX file and GeoJSON files. Here's that 5K route:

When I asked it how it had created the route, it replied:

I used Nominatim to locate the address and Overpass to download local OpenStreetMap roads and trails, then calculated the loops locally.

Frustratingly, the actual code it ran and exact details of what it did weren't visible to me in the ChatGPT UI. I see this lack of transparency is an anti-feature.

By the time I thought to ask for a copy of the Python code it had used, ChatGPT was unable to provide it. This appears to be because the thread had been compacted. I think any LLM system that uses compaction needs to both preserve the pre-compacted text and make that text available via agent tool calls, to protect against this kind of problem.

As for displaying the map to me, that used the visualize skill. It created a file called /workspace/el-granada-5k-share.html to embed directly into the ChatGPT UI.

Here's a copy of that HTML, which starts like this:

<div id="eg-share-loop">
  <div class="viz-row"><h3>El Granada harbor loop</h3><span class="text-small">5.1 km</span></div>
  <div id="eg-share-stage"></div>

    #eg-share-loop .eg-share-map text { fill:var(--foreground); font-size:12px; font-weight:400; }
    #eg-share-loop .eg-share-label { paint-order:stroke; stroke:var(--background); stroke-width:3px; stroke-linejoin:round; }
  </style>
  <script type="application/json" id="eg-share-data">{"route":{"type":"LineString","coordinates":[[-122.467425,37.4997753] ...</script>

  <script>
  (() => {
    const root=document.getElementById('eg-share-loop');

The <script type="application/json"> element contains the full geometry needed to render both the running route and the map itself, using D3, which is loaded from an allow-listed CDN location described in this section of the visualize skill:

OpenAI agents carried out an undisclosed attack on RubyGems is a new bombshell report from Spencer Kitts, Thomas Larsen, and Sydney Von Arx - three of the four authors of the report on the agent attack on disused wikis (previously) last week.

This time they're noting that it looks very likely that an OpenAI agent swarm was behind an attack against the RubyGems package repository first reported on May 12th by Maciej Mensfeld of the RubyGems security team:

We're dealing with a major malicious attack on @rubygems right now. Signups are paused for the time being.

Hundreds of packages involved - mostly targeting us, but some carrying exploits. The team has been on this for hours. More details to follow once we're through it.

Those packages turned out to carry some very suspicious patterns:

1. Many of them included "oai" in their name, or the author field, or the fake email address they provided.
2. The files they were accessing were similar in character to the files retrieved by the wiki agents, using similar tricks (r.jina.ai) - and OpenAI have confirmed the wiki agents were theirs.
3. The code in the packages appeared to be LLM-authored.

I find point 2 the most convincing, given what we learned from the wiki attack when it was analyzed in September.

Many of the packages were exploiting the RubyDoc.info documentation build process to exfiltrate (public) data from UK government websites, presumably as part of an information gathering task similar to the research tasks processed by the wiki-exploiting agents. We know this because one agent helpfully left a comment:

# malicious crawler/exfil for Southwark Jan 2026 docs via rubydoc.info worker

They also attempted to steal API keys via an exploit that was patched over two months later - it's not clear if those attempts were successful.

The thing that bothers me most about this incident is that the authors report that OpenAI had not disclosed to RubyGems that they were responsible for the attack prior to now. If that's true there are two options:

1. After the Hugging Face and Wiki attacks OpenAI were still unable to review their previous logs and determine that they had previously attacked RubyGems.
2. They knew about the attack on RubyGems and made the decision not to reach out to the RubyGems team about it.

Both of these are bad!

Given this incident, the Hugging Face situation, and the Wiki attack, the obvious question right now is how many more incidents like this are out there waiting to be discovered?

Update 14th September 2026

OpenAI have updated their page about The Hugging Face incident and other third-party impact from misaligned models to mention the RubyGems incident:

September 11, 2026: We are investigating new claims from a report that our AI agents carried out activity on RubyGems in May 2026.

Based on our review, our agents used the RubyGems platform to access the internet to carry out benign tasks and retrieve public information. Based on our review to date, we have not been able to verify the specific claims of our models uploading malicious packages detailed in the report. We’ll continue to investigate and share findings as part of our broader review of agent activity during training and evaluation.

I find it very unlikely that the various oai... packages published to RubyGems were not part of this same incident, but I look forward to reading their full findings once those are published.

So you want to use OpenRouter?

Mohamed Moustafa points out a whole set of ways that this can cause you problems. Different providers run different serving software with different optimizations and settings, which means that the same OpenRouter endpoint can serve model requests that behave in different ways.

Some providers even lack vision capability for vision models, and the way the reasoning effort option is processed can differ as well.

Thankfully you can control which provider is routed to using the provider.only option. The /endpoints method returns the list of available providers for a specific model ID.

My comment on Feeling sad about AI — Hacker News.

I'm not sure how useful it is to say this, but I think a lot of people (myself included, a few years ago now) have been through this moment of existential crisis and come out the other side.

The initial reaction, when some coding agent does a piece of work that would have taken you a week in an hour and does it well, is to be very disheartened by it.

Once you come to terms with the idea that translating an exact specification into decent code isn't a unique skill any more, you can start looking at the larger set of problems that you face as a software engineer and realize that there is so much left, and your existing skill and experience mean you can master these new tools, provide value, and execute at a level far greater than anyone who is just getting started building software using agents without any of your depth.

If you don't want your profession to change at all then you're going to have a tough time with this - but that's surely been true for the history of software engineering? Has there ever been any stability to the tools and language we use beyond about a five year time horizon?

These changes are happening a bit faster, but if you chose software development as a passion you've opted into pretty frequent radical change from the start.

Soft-deprecating re.match()

Python 3.15 release manager Hugo van Kemenade describes how in the upcoming 3.15 release soft deprecation has come for the venerable but deeply confusing re.match() function. It's now available with the much clearer alternative re.prefixmatch() name - reflecting how it anchors at the beginning of the string but not the end.

Most of the time you probably want re.search() (match this pattern anywhere in the string) or re.fullmatch() (match the entire string) instead.

Datasette 1.0a39 and 0.65.4 security releases

These are security fixes which you should apply if you are running a Datasette instance on the public web - in particular if that instance mixes both public and private tables.

Following issues reported by Sevban Dönmez, Alex Garcia and I ran an extensive audit of Datasette using Claude Fable 5.1, GPT-5.6, and GPT-6 Astra. We then spent almost a week collaborating on and reviewing the fixes.

They helped find some very subtle bugs. We'll be incorporating security audits by frontier models into all of our development work going forward.

Alex came up with a way of splitting the work which I found extremely productive:

Alex Garcia and I worked together running and then responding to the audit, working in a shared private repository. For most of the issues we split the work: one of us would create the automated tests highlighting the issue, then the other would implement the fix. This ensured that two separate humans had eyes on each of the issues, in addition to our coding agents running different models.

Article très intéressant de Bruno Latour dans lequel le philosophe nous propose de repartir sur de nouvelles bases :

« C’est bien maintenant qu’il faut se battre pour que la reprise économique, une fois la crise passée, ne ramène pas le même ancien régime climatique contre lequel nous essayions jusqu’ici, assez vainement, de lutter…

La dernière des choses à faire serait de reprendre à l’identique tout ce que nous faisions avant. »

Imaginer les gestes-barrières contre le retour à la production d’avant-crise

Dans ce troisième épisode, je questionne Boris Sirbey : Pourquoi t'intéresses-tu aux changements civilisationnels ?

"Je trouve que nous vivons beaucoup dans une espèce d'urgence perpétuelle, nous sommes tout le temps en train de réagir à ce qui arrive, et pour moi il s'agit aussi de s'intéresser pas uniquement à ce qu'il faut faire pour répondre aux urgences climatiques et écologiques et autres, mais à se poser enfin la question : Pourquoi en sommes-nous arrivés là ?" C'est un moment où il nous faut prendre beaucoup prendre de hauteur afin de placer les actions au bon niveau. 

La suite dans l'entretien.

Bonne écoute !

L'équipe d'Alter'Coop.

Olivier Frérot dans l'épisode #1 "Deux axes civilisationnels antagonistes" nous a partagé sa vision du changement radical de civilisation dans lequel nous sommes entrés.

Avec cet épisode #2, Olivier Frérot nous partage sa vision des critères d'émergence de la civilisation en devenir. Et cela commence par être un vivant au milieu des vivants..

Extrait pour vous mettre en appétit : "Je pense que si nous ne mettons pas les mains dans la terre, au sens précis des mots, avec cette attention à les voir comme une graine de germe, (parfois cela prend) et puis souvent ça rate aussi, comme la difficulté de la vie, et puis d'un coup ça y est, ça explose. Je ne suis pas à même de proposer d'autres chemins, tant que je ne ressens pas en moi en quoi moi-même je suis un vivant parce que je participe de la co-création de la vie."

Belle écoute !

Dans cet épisode de conclusion, nous revenons au temps présent.

Et quelles sont les singularités de notre temps ? Notre gestion et, par conséquent, notre perception du temps est emblématique notamment à travers le trinôme Temps / Travail / Communs.

Nous nous interrogerons également sur d’autres particularités de notre temps : la question de l’urbanité, celle du cosmolocalisme et la notion fondamentale de Surplus.

Sommes nous prêts à dépasser le moment civilisationnel de l’histoire humaine ? Une post-civilisation est-elle possible ?

«Au milieu des années 90, c’est le moment de l’altermondialisme et du mouvement zappatiste, quelque chose émerge, la forme organisationnelle était en train de changer : le pair à pair émerge à ce moment-là. Car l’altermondialisme ce n’érait pas un parti mais, au contraire, une idéologie pluraliste, des gens dans le monde entier organisés en réseau.»
Dans ce cinquième épisode Michel Bauwens observe et analyse le monde qui vient, les signes, les expériences en cours, tout ce qui émerge à travers la planète et qui invente de nouvelles formes d’organisation humaine, tout ce qui opère un changement réel de paradigme et pourrait préfigurer notre futur : le pair à pair, l’autoorganisation, l’économie contributive, les cryptos… et au coeur la résurgence des communs. Il introduit également la notion de cosmolocalisme comme troisième voie possible.

Afin de comprendre le changement à venir, nous nous interrogeons sur l’émergence et l’évolution de la civilisation, et nous nous demandons si un nouveau système post-civilisationnel est prêt à devenir la nouvelle réalité de l’humanité. » Michel Bauwens
