Track AI Agent Traffic to Your Docs with Vercel Log Drains, Hookdeck, and PostHog Build a server-side analytics pipeline with Vercel Log Drains, Hookdeck, and PostHog to capture every request to your machine-readable docs (.md and llms.txt) and see which AI agents are reading them.

Anyone with llms.txt/.md/agent-facing docs knows that client-side tracking doesn’t work (no browser, no JS). Here's what does:

Vercel log drains → Hookdeck → PostHog.

Here's another from my "work" this morning. You can fill in the blanks 😆

Haha! I'm sorry.

Prepped a few slides for HackBarna and this was an asset intended up with 🫣

Wally/Waldo from "Where's Wally/Waldo?" in a crowd, holding a Webhook logo. There is a sign in the center that says "¿Dónde están los webhooks de Wally?", which is "Where's Wally's Webhooks?" in Spanish.

Turns out that Wally was an engineer working on event-driven systems in Spain.

Our local Heron by the burn in Dollar.

The Deck product is very new to me. Feels more like a solution for a product manager, instructing a team to build various features - or trying to build the same feature in different ways - simultaneously.

I think it's worth giving it a try.

Been hands-on with Verdent for a few weeks in early access.

Already smoother than I’ve had with Roo Code + Gemini/Claude.

Two highlights:

1️⃣ Better overall plan flow
2️⃣ Parallel agents + isolated git worktrees via desktop app

Access now open → www.verdent.ai

Housekeeping will appreciate that. They've only just finished mopping down and repainting after the last guest

Pleased to say that I made it through the night 👹

What other changes are you making to your docs to make them more accessible to LLMs and developers targeting their use?

Should we have a dedicated llms.txt under /docs?

Our OpenAPI spec is pretty big, so should we create dedicated .md versions for each endpoint? Or do you think we should focus on improving the related product docs with more examples?

1. Copy for LLM: copies a markdown version of the current doc to the clipboard
2. View as Markdown: view any docs page as markdown with a ".md" extension
3. llms.txt at the root of the website: Covers docs and other content that sits outside of docs

A few recent DX LLM-focused updates we've shipped on the Hookdeck docs...

See the blog for examples: hookdeck.com/blog/transf...

The Hookdeck Event Gateway allows full control over transformation and filter order in your event pipeline.

Options include:
→ Filter or transform first
→ Cleanup data pre-delivery
→ Deliver only essential data

Available via dashboard UI and API.

Do I get any points for the t-shirt I wore during my recent Stripe Developers London Meetup talk?

Does anyone recognize it?
