All about coding

LLMs work with the numbers behind your text rather than the text itself.

Rails.application.console runs a block only when bin/rails console starts, never in web or job processes.

Once a chat takes a wrong turn, the model gets lost and does not recover.

LLMs are finding bugs in mature, stable software.

Claude goes above and beyond what is asked and guesses what you might want.

Codex builds the status line from an ordered list of built-in item names.

Claude Code writes the session JSON to your script's stdin and displays what it prints back.

Both phrases cut Claude's sentences in half when explaining code.

What the HANDBOOK.md benchmark measures, why the best model still fails two of every three tasks under strict grading, and what that means for the rules you keep in CLAUDE.md and AGENTS.md.

One week of agent-first backend work in the logs: 2,200 session files across four tools, 350 prompts typed by hand, and which checks actually found real defects.

Where Claude Code, Codex, Cursor, Amp, opencode, and pi store session logs, which formats they use, how long they keep them, and what remains undocumented.

One block in CLAUDE.md and AGENTS.md that makes coding agents write throwaway scripts in Ruby instead of Python or bash, so you stay the reviewer instead of a rubber stamp

Documenting a weekend experiment with codex /goal command, using superplanning for initial planning and fizzy cli skill for task management.

Real stats from two months of agent-first development: four coding agents (Claude, Codex, Cursor, Amp) competing on every feature across 951 sessions

Capture the session state before compaction and restores it after.
