We're now just a week away from my fifth year at @renderatl.com! Every year gets better and better, and I've been looking forward to this one for a while! Hoping to see some familiar faces and some new ones!

I've been using a custom tool for collecting telemetry from my agents and it's been a game-changer for visibility into ongoing work when I'm AFK. The best part is that sessions get summarized as I go, and get taken into account by my auto-standup tool, summarizing yesterday's work and blockers.

The screenshot displays the “Active Sessions” panel of an internal LLM / agent orchestration UI.
Key points for developers:

Five concurrent sessions are listed, each represented by a card that shows: • Session name and status tags (e.g., “Executing tool”, “Processing”, “Waiting on LLM”, “Streaming response”).
• Model name (all “Claude Code” except one “Codex”).
• Real-time activity metrics:
– Last-active timestamp (e.g., “14 s ago”).
– # of LLM calls and tools invoked.
– Token I/O counts (“in / out”).
• Working file path for the session.
• Elapsed duration.
• Controls: “View spans”, “View transcript”, “Summarize

The screenshot shows a chronological activity/telemetry log that records:

Bash commands that print and cat multiple script.js files (configDialog, resetConfirm, styleDialog, wizardPage, create.js, etc.).
Tool-level searches inside the codebase (kizen-plugin-reference/search_plugins and mcp_kizen-plugin-reference__find_method) for “frameless”, showViewInModal, data-script="cancel", etc.
File reads of several CSS and JS view files under
/Users/keegan/Developer/plugins/plugin-dev-keegan/src/views/...
A write operation to src/views/configDialog/script.js.
Inline code comments indicating the purpose:
“Wizard POC — “Edit Brewery Config” dialog. … Opened frameless via showViewInModal(“configDialog”, …”
Durations for each step (e.g., 59 ms, 22 ms).

For some reason it’s been hard for me to get back out on my bike. Life has been taking priority I guess. Finally out for a long ride today (with a beer stop) and loving it!

So Fable 5 is pretty neat - been playing around a bit at work seeing if it can build plugins for me. Expensive! 29 cents to say hi.

$Summary The screenshot shows a cost analysis for sending a simple message like "hi" in an AI agent environment. It outlines the token usage and associated costs when sending a message through an AI interface. The breakdown includes both input and output tokens and highlights the difference in cost between a bare session and a raw API call. This information is useful for developers looking to understand cost implications in AI interactions, particularly with Claude-Class pricing. Extracted Text How much does it cost to say hi? Saying "hi" is never just "hi" in an agent environment. Rough breakdown: - Your message: ~1 token - What actually gets sent: the system prompt, tool definitions, environment info, etc. – typically 10–20k input tokens before you've said anything With Claude-Class pricing (~$3/M input, ~$15/M output), a bare "hi" in a session like this costs roughly $0.03–0.06 for the first turn, mostly from the fixed context overhead. The reply itself ("Hi! How can I help?") adds a fraction of a cent. If you mean a raw API call with no system prompt: ~5 input + ~10 output tokens ≈ $0.0002 — effectively free. If you want, I can pull your actual AI usage stats to see what your average session costs. 📘 Build · Claude Fable 5 · 10.4s Build · Claude Fable 5 Vercel AI Gateway 22.0K (2%) · $0.29 ctrl+p commands$

With the deprecation of DALL·E 3, I finally got around to updating thirsty.bot to use gpt-image-1 for recipe images. I like the consistency and elegance of the outputs, but it does miss some of the character of DALL·E.

Excited to see a new performance-focused app from @gentler.app!

Back in 2018 or so when I was in college, I drove up the coast of California on Highway 1 with my grandpa's old Nikon and shot a few rolls of film. I never developed them and thought they got lost when I moved to Texas. My Dad found them in his house recently! Such a nice surprise #photography #film

Been working toward this challenge on @gozwift.bsky.social all year! Happy to cross it off in the final days before traveling for the holidays. After this week, all outdoor riding for the rest of the year!

New Oura UI is pretty nice! Love to see the return to serif fonts in design lately.

Did a 105 mile bike ride, got married, and went on a mini-moon right after. Each of those events are pretty clear in my cardio load chart 👀. It was the longest break I’ve taken in a while, feels good to be back to a productive training state!

Over the weekend I saw some people at my gym nearly come to blows over the free paddle board rentals. I was happy in my kayak to watch the drama from a distance 🤣 Just another reason the kayak is superior to the paddle board!

A year ago tomorrow I did my second longest bike ride (at the time) - 13 miles! Now a year later I’ve done multiple 100km rides and I’m getting ready to do 100 miles! Crazy how a year changes things.

Worked on deploying a new service today. Exciting things coming regarding developer enablement! Side note, working on Docker builds and infrastructure stuff is one of my favorite use-cases for Github Copilot now. It did a great job working through some of the trickier bits with me.

A breakdown of time spent on programming languages today:
Typescript - 2:01
JSON - 1:44
Terraform - 0:32
Docker - 0:31
Bash - 0:19
JavaScript - 0:17
HTML - 0:10
TSConfig - 0:06
Git Config - 0:04

Did an AI make this ad? There’s no AI in IPA unless you get real creative 🤣

I've been seeing a steady degradation of my performance scores for keegan.codes on @vercel.com in the last few days, with no deployment changes on my end. I wonder what's going on 🤔. Traffic patterns seem fairly steady in the same period.

A graph of my performance score ranging from 0 to 100. 30 days ago it was a bit unstable, but mostly leveled out above 90% until a few days ago, where it steadily trends downward toward 50%

First night in my own bed after Render and my sleep is already improving. Feels good to finally sleep more than a few hours!

Since I've been using @obsidian.md a lot lately, I'm trying out a canvas for diagramming some of the business logic that eventually needs to get built. I'll be breaking this down into phases but it's nice to see everything in one place.

Some of my best ever sleep and recovery numbers last night! No alcohol, a highly productive weekend (so no residual stress going into the week), and a relaxing Sunday with an early dinner all contributed. Now to replicate this during busy periods 😬

Ran out at lunch to get my Close Your Rings pin from the Apple Store! I wish there were more of these pins for other limited edition awards, it's pretty nice!

Uh seems like a pretty niche concept for a podcast

Hey Keegan,
Ever thought of starting a podcast about leveraging ai in marketing to acquire 3-4 enterprise deals with various industries per quarter?

Apple Intelligence decided to summarize the tiny legal disclaimer at the bottom of the email instead of the main email body (what the upgrades actually are) 🤦🏻‍♂️ This shit is so useless

This is a pretty scary phishing scheme for Apple IDs. My grandmother got this today. Thankfully she was suspicious and knew to ask me to confirm, but I’d bet this one works pretty often.

My heart rate monitor dropped out after a few minutes. Strava AI was real insightful on this one.

Low average heart rate of 14 bpm with max of 162 bpm suggests a controlled, strategic effort.

I built a little Christmas sweater-style drawing app over the weekend. It's still a little rough but maybe I'll make it public tomorrow to celebrate the holidays 🎄
