TinkerHoodSubscribe

Practical AI, worked out in public.

TinkerHood tries AI agents and the tools around them on real tasks, then writes down what works and what doesn’t. Guides, comparisons, and weekly Field Notes on Claude Code, Codex, Cursor, and more. Every entry shows how far we checked it.

Writing skill descriptions that trigger

What we measured when we compared a vague skill description against a sharp one on Codex, with the trigger counts and a note on sample size.

Each dot is one prompt. Filled: Codex read the skill.

Field notes, issue 1

Our first weekly issue, one skill test across three hosts, a September Claude Code change worth knowing, and one failure we're still chasing.

Loads checked on Codex only. Other hosts remain not checked.

Tested this week

One small skill was installed in Codex and Claude Code. Live loading was checked on Codex only.

A change that matters

Claude Code added an AGENTS.md fallback in September 2026. Check the version you use.

An honest failure

A missing reference was not caught by the format checker, and its failed read did not appear in the final answer.

Guides

Each cover is drawn from what we actually checked.
