Playing with Claude skills

Using skills we can capture *why* software components are built, not just the *how*, giving developers better context when working with unfamiliar code. This isn’t about replacing developers, it’s about empowering them. We’re now exploring ways to capture skills from conversations, documents, and the natural flow of work.

For the last couple of weeks I have been playing with Claude skills.

It’s a cool way to package knowledge on how to do stuff in a prompt which can be retrieved any time your agent needs it. They work with Claude, but you can easily integrate them in any LLM-based process.

My first experiment was building a skill about our company. Read the website, read some internal documents, read technical documentation, distil a context that can be used any time I’m writing or thinking about business stuff. But the most interesting aspect is that everybody on our team can now use the same context for whatever work they are doing.

The next experiment was to build a skill to create Spritz agents (there’s a very good skill-building skill on Claude, which helps a lot with the building and packaging of skills). I showed Claude the blueprint for agents that we use every day, then showed some fully developed agents.

Then I tried to build a simple “hello world” agent from scratch with this prompt:

Build a Hello World Spritz agent. It should ask for the user name, then use the Anthropic API to generate a greeting. Deploy the agent on AWS using the CLI and test it. Ask me for an API key when you are ready.

I was able to obtain a working agent in about 10 minutes, but it took a few nudges here and there where the skill didn’t cover details.

At the end of this process I prompted:

Based on the experience of this job, update the skill file so next time we will be able to complete the task without obstacles. Do not include in the skill any specific information about this agent or my development context.

The second time it worked end to end.

I have since tried to build a bunch of different agents, always adding more details and nuances to the skills.

This is not (just) about production

Of course this is not about replacing developers, it’s about empowering them. The agents I build will not be used in a production environment; they are mostly proof of concept.

Using skills (or some similar prompting technique) we can capture why various software components are built, not just the how, allowing developers to have a much better context when they need to interact with code they have not created, or even when they go back to a project after a while.

They are an amazing teaching tool to explain to others how things work.

For now we have simply started a GitHub repository with the skills we have built so far. It’s easy to ask Claude, ChatGPT or any other tool to find and retrieve skills from the repo and use them. Now we are figuring out new ways to capture skills from the flow of work we do, from conversations we have, from documents we create.

Yet another step towards an interesting future.

Magic Moments ✨

When AI models start asking each other for help without being told to, something magical happens.

One of the cool aspects of having a dozen different MCP servers connected to Claude are the random serendipitous interactions that emerge.

Yesterday, I was working on a little programming project. Opus 4 was chugging along nicely, reading files on my Mac, deciding how to implement something, checking data against a source I was working on. The usual AI assistant stuff, really.

Then I noticed something unexpected in the logs. Claude had fired a call to the OpenAI MCP server (that little experiment I did to allow Claude to ask questions to OpenAI models). I paused to see what was happening.

Claude had asked GPT-4o how to read the end of a file. Nothing groundbreaking — just a simple technical question. GPT-4o provided an answer, and the process continued seamlessly. If I hadn’t been paying attention to the logs, I would have missed it entirely.

Here’s the thing: I’m fairly certain this information exists in Opus 4’s knowledge base. It’s not like reading the tail of a file is some obscure programming technique. But for some reason, in that moment, Claude decided it wanted a second opinion. Or perhaps it needed some comfort from another model?

It felt a little magic.

The magic of AI search

I just built yet another MCP experiment.

First I created a Python script to process .md files: chunk them, create embeddings, store everything in a PostgreSQL database.

Then I built an MCP server which can search the database both using semantic search (embeddings) and more traditional full text search as a fallback mechanism.

I find absolutely fascinating watching Claude interacting with this tool, because it’s not just about converting my request to a query, it’s the reasoning process which happens in order to find what it needs which is brilliant.

Let me show you an example:

Building a WordPress MCP Server for Claude: Automating Blog Posts with AI

Building a custom MCP server to connect Claude directly to WordPress, enabling automated blog post creation with proper formatting and intelligent categorisation.

Third day, third MCP experiment (inspired by a quick conversation with Dave).

This time I connected Claude with this WordPress blog.

At the end of the chat that I used for the whole process of writing, building and installing the tool on my Mac, I asked Claude to write a post about the experience.

Of course I wouldn’t allow Claude to post unsupervised original stuff to my blog like I just did, but as Dave was pointing out, these are our new writing tools, being able to post directly without having to copy and paste just makes sense.

To be honest I would rather do this with ChatGPT, but apparently MCP integration is not available yet in the UK yet.

Check below to see Claude’s original post.

PS: it also categorised and tagged the post automagically ❤️

GroceriesGPT

A friend this morning shared a list of vegetables, noting how hard it is to eat 30 different ones in the same week.

I immediately turned to my AI chatbot to ask to create a list of commonly eaten vegetables, and of course I got a very good one.

At that point I thought that it would be nice to add that list to my next grocery order on Ocado.

And this is where the magic ended.

My chatbot doesn’t talk to the Ocado app. And I actually use more than one bot, sometime I go with ChatGPT, sometime I go with Claude, they are both good and continuously improving and I like to pit them against each other.

ChatGPT has a plug-in architecture which potentially would allow to connect with other applications creating custom GPTs, but so far I haven’t seen any particularly good application. And what would be the idea there? That Ocado would have to build a custom GPT? And what about other chatbots? I don’t really want to be siloed again. I’m happy to pay for services, even Google, but leave me free to connect.

Meanwhile I’m sure that somebody at Ocado is already thinking on how to integrate an AI in their app (if you aren’t, call me), and while this will be a nice feature to have, it will be yet another AI agent unable to talk with my other agents.

Maybe the solution is similar to what Rabbit appears to be working on: teach AI to use UI. Avoid altogether the challenge of getting companies and engineers to agree on open standards and just teach AIs to use shitty incompatible interfaces of our apps.

AI interoperability might be one of the most interesting future problems that we will face.

I want the AIs I pay for to collaborate, not to compete.
