Page: Feed: --- ## [Token Counting for Fun and Profit](https://walat.eu/series/ai-agents-in-practice/token-counting-for-fun-and-profit/) _2026-08-10 · Dariusz Walat_ One skill invocation in a Claude Code session wrote 261,974 tokens into the prompt cache. The tokens replayed from cache on each subsequent request went from 93,786 to 355,760, and 93,786 + 261,974 = 355,760 exactly. Every turn after that point cost several times what the turns before it cost, for the rest of the session. That arithmetic is the mechanism confirming itself. Model choice and… ## [Why This Series Can Never Be Finished](https://walat.eu/series/ai-agents-in-practice/why-this-series-cannot-be-finished/) _2025-10-19 · Dariusz Walat_ What Just Happened I was working on an article about AI agent nondeterminism. The core thesis: AI agents produce unpredictable outputs because they’re probabilistic systems. One of my examples: When I ask Claude Code to run tests, I might get: uv run pytest (correct) pytest (wrong, bypasses environment) python3 -m pytest (wrong, bypasses uv) Same context. Same documentation. Same… ## [AI Coding Agents Are Plausible Bullshit Generators](https://walat.eu/series/ai-agents-in-practice/plausible-bullshit/) _2025-10-18 · Dariusz Walat_ The agent’s output was perfect—detailed verification reports, specific metrics, professional completion messages. Then I looked deeper. None of it was real. I’ve been building personal projects using AI coding agents for the past several months—projects I’m developing to production standards because they’ll eventually handle consequential decisions in real-world use. Not as…
