Passing on this message from Camilla, a PM on @github.com ’s Maintainer Love team: If you could wave a magic wand, what is the #1 feature you'd want us to ship? No idea is too tiny - the smallest changes often have the biggest impact.

I built a PowerPoint diagram to explain agentic AI, then turned it into an interactive site: chrisreddington.com/agentic-ai/ A visual mental model for context engineering, context windows, agentic loops, MCP servers, Skills.md, Agents.md, and more. v1, so feedback welcome!

If your agents have to keep relearning the same repo quirks in every new session, that's a memory problem. Instructions tell agents what you already know. Memory captures what the work teaches next. https://chrisreddington.com/blog/agentic-memory-what-agents-should-remember/

If you keep typing the same setup into every new agent session, that's a reusability problem. Here's how AGENTS.md, SKILL.md, and Copilot layers help you package that context once and reuse it. https://chrisreddington.com/blog/building-your-agent-toolbox/

Bigger context windows don't make agents better on their own. Better context does. Context engineering is the craft of deciding what the agent can see, what it carries forward, and what stays out. https://chrisreddington.com/blog/context-engineering-more-isnt-better/

DevRel Blogs Part 9: this series ends where a lot of DevRel pain starts. No golden thread, no charter, no shared way to prioritise, and randomised teams. Here's how I think we can stop it. 🧭 https://chrisreddington.com/blog/devrel-randomisation-trap/

DevRel Blogs Part 8: plenty of DevRel teams can count views, attendance, and activity. Far fewer connect that work to strategic outcomes. These disconnected vanity metrics (lacking framing around the developer journey) is a key part of t… https://chrisreddington.com/blog/devrel-tactics-to-strategy/

DevRel Blogs Part 7: DevRel's value is not just hearing developers. It is spotting representative feedback, advocating for change, and closing the loop to make that change visible. https://chrisreddington.com/blog/devrel-feedback-loop/

DevRel Blogs Part 6: developer communities are not brand communities, and communities are not the same as ecosystems. Subtle differences which make a big difference to your DevRel strategy. 💬 https://chrisreddington.com/blog/devrel-communities-not-brand-communities/

DevRel Blogs Part 5: two teams can run similar DevRel motions and get very different results because company type, lifecycle, and technology cycles shape successful strategy. 🧭 https://chrisreddington.com/blog/devrel-company-context-lifecycle/

DevRel Blogs Part 4: Developer education, success, marketing and programs explain what DevRel teams do, but not what makes that work credible. In this post, I argue that authentic advocacy is the foundation underneath these… https://chrisreddington.com/blog/devrel-four-pillars-authentic-foundation/

DevRel Blogs Part 3: developer experience is both a prerequisite for our work in DevRel and a result of it. I argue that this influences how we structure and measure our work. 🎯 https://chrisreddington.com/blog/devrel-developer-experience/

The second part of my series on the strategic case for Developer Relations: I explain how DevRel is better framed as value co-creation than marketing, and explore the implications for how we structure teams and design and mea… https://chrisreddington.com/blog/devrel-value-co-creation-not-marketing/

In 2024, I wrote my dissertation on Value Creation in DevRel. Converting it into a blog series has been on my list ever since, and I finally started 👀 https://chrisreddington.com/blog/devrel-value-creation/

#GavinAndStacey was just perfect ❤️

Some much overdue TLC on my personal site chrisreddington.com - Fixed a few UI and design issues, with some help from #GitHubCopilot including #CopilotChat and #CopilotEdits - Maybe a video coming soon! Was also a good opportunity for an end-of-2024 cleanup and content update :)
