> Every entry is a build story - what got made, why, and what broke.

## Posts
- [The token was never in the screenshot](/posts/telegram-bot-skill): Automating @BotFather in a browser to give every project its own Telegram push bot, and the gotchas along the way.
- [I built a pipeline that scouts real pain points for me](/posts/idea-scout): A deterministic pipeline reads community pain points and frames each as a shippable idea with a target user and a 30-minute demand test.
- [Your website is a blank page to ChatGPT](/posts/agent-ready): AI crawlers don't run JavaScript, so JS-rendered sites are invisible to them; a deterministic scanner measures and fixes agent-readability.
- [The model never gets to make up a number](/posts/vnstock-anti-hallucination): A production LLM stock agent where deterministic code owns every number and the model only reasons on top of them.
