MOST OF THE TIME

One tool per task. Two questions.

Board report Invoice sorting FOR EACH TASK Which does it better right now? Which burns fewer tokens doing it? OR
WHEN BEING WRONG COSTS MONEY

One does the work. The other checks it.

1 · THE TOOL THAT DID THE WORK

Summarize what you did on this task and list the files another AI would need to review your work.

Include the goal, who the output is for, the rules you followed, and anything you were unsure about.

Put all of it in a code block.

2 · THE OTHER TOOL · SAME FOLDER

You are reviewing work another AI did in this folder. Here is its summary.

Read the files it points to. Check the work against the goal and the rules.

Tell me what is wrong, what is missing, and what you would change. Do not rewrite anything yet.

THE HABIT

Three reasons to move a task.

You hit your usage limit It keeps failing the same way A new model comes out
3 OR 4 FOLDERS. NOT 30.

Test without fooling yourself.

TEST FOLDER FRESH INPUTS ONLY PAST OUTPUTS Compare both to your output. THE WINNER + THE DATE
NEVER REBUILD. RE-RUN.

Recap

One folder per task, on your computer. Save the instructions twice. CLAUDE.md and AGENTS.md. One tool does the work. The other checks it. Re-test on three triggers. Limits. Failures. New models.
