2 of 8 compactions dropped the body of a skill I had invoked earlier in the session, even though the Claude Code docs say invoked skill bodies are re-injected: both were /compact sent through claude -p --resume , while the 6 compactions that ran inside a single process re-attached the skill every…
For two weeks I woke up and checked for a markdown file that should have been written at 3:00 AM. On 8 of 14 mornings it either wasn't there, was empty, or showed up after I'd already finished my coffee. The job was simple. A macOS launchd agent ran Claude Code headless with claude -p every night…
I use Claude Code most of the day (Codex CLI too), and three small things kept getting in my way. The first one: I'm halfway through writing my next prompt while Claude is still working on the last one. Then I notice it heading the wrong way, or I realise I need to ask something quick first. My…
Two statements about Claude Code mods, both true, both from Anthropic's own docs: The module runs in a sandbox of its own, with no DOM and no Node. "Mods aren't sandboxed." The first two days of the mods launch have been one long argument about which of these is the lie. Neither is. The confusion…
You told Claude Code “always run the formatter after editing” and “never run rm -rf ”. It listened, until it didn’t. A rule in a prompt is a request — it can be forgotten, skipped, or missed after a context compaction. A hook is not a request. It’s a shell command that runs automatically at a…
I like /goal in Claude Code. You say what "done" looks like and Claude keeps working until it gets there. What bothered me is who decides it got there. After every turn a small model (Haiku) reads the conversation and answers "met", "not yet" or "impossible". I tested what that judge can see. It…
Last Friday, while cross-debugging a payment refactoring branch, I had Cursor open on my left monitor for frontend reviews and Claude Code running in my terminal on the right. To let both AI assistants inspect database schemas and query logs, I hooked up 4 MCP servers to each environment. When you…
On 2026-09-18 we took the reference.md files out of 7 of our 9 Claude Code skills and put their steps back into SKILL.md , against the docs' advice to split. Today our 8 skills are one file each, 107 to 421 lines. A same-week measurement suggests the split would have worked, and one of our own runs…
Claude Code Mods Just Turned Agents Into a Platform On October 1, 2026, Anthropic shipped Claude Code v2.1.287 with a feature called Mods — JavaScript and TypeScript functions that hook into the agent's execution pipeline, intercept tool calls, render custom UI, and reshape how the agent behaves…
