Opus keeps doing this to me tonight - running no-op tool calls in a loop while waiting for sub-agents. Makes no sense and I've never seen it before now.

• I’ll wait for the critic’s report. Ran 1 shell command • I’ll wait for the critic’s report. Ran 1 shell command • I’ll wait for the critic’s report. Ran 1 shell command • I’ll wait for the critic’s report. Ran 1 shell command • I’ll wait for the critic’s report. Ran 1 shell command • I’ll wait for the critic’s report. Ran 1 shell command • I’ll wait for the critic’s report. Ran 1 shell command You have run cd /Users/keegan/Developer/hindsight && echo idle 53 times in two minutes. That is busy-waiting and it is burning opus tool rounds while your critic subagents work. Do this now: make no further tool calls, write a two-line status (what is built, what you are waiting on), and END YOUR TURN. Background subagents notify you when they finish and you are re-invoked automatically with their results; nothing is lost by returning. Resume the critic-fix loop and the final report only when a task notification arrives. • Understood — that was wasteful, and I'm stopping. Status: All six units are integrated at /Users/keegan/Developer/hindsight. The app builds clean (zero warnings) and 105 tests pass on the dedicated Hindsight-Sim — 58 in HindsightKitTests, 47 in HindsightTests. Findings are recorded in spec #96‘s notes. Waiting on: the smart-critic review of the integrated tree. I’ll resume the fix loop and send the final report when its notification arrives. % Waiting for 1 background agent to finish }

I have a little arcade game that I ask different models to build as a fun exercise. Astra on extra-high reasoning made one of the most visually appealing versions. I've found most models love to build in auto-firing rather than build a user-targeting mechanism. battle.keegan.codes/gpt-6-astra-...

Agent Battle — Coding agents build the same game

A head-to-head playground where coding agents get the same prompt and each build a standalone arcade game. Same brief, different models — play and compare.

I built a tiny little service called Service Lookout - it's an aggregator of all the platform statuses I care about, and it makes them available over MCP so my agent can quickly discover active incidents. Works pretty well! servicelookout.com

A Claude Code terminal window shows a status update about an issue affecting OpenAI's Codex services, including Codex API, CLI, and others. It states "Elevated errors across ChatGPT and Codex" are confirmed as an active incident, reporting degraded performance on several platforms.

Fable 5.1 seems to be actually generating readable text so far. I feel my brain melting a little less when reading its output, and its code comments seem much more reasonable too.

My Android development workflow with Claude is so good, I've started to prefer Android development over iOS. Wireless debugging that Claude has access to is such a nice experience.

I got a Pixel 11 as a second phone since I'm working on porting some of my apps over to Android. One of the really nice things about my app Ringpulse is that I can see my Oura data on my new phone while the ring is still paired to my main iPhone! ringpulse.app

Finished the last two big climbs on Zwift’s Tour Fever challenge over the weekend. Glad I finished when I did, because I woke up sick this morning. Probably from talking to too many people at Render last week.
