chamnan

Set up chamnan in this repository for the first time — build the architecture index, measure how well the code describes itself, fill in missing file comments, and record a baseline. Run once per repo.

Write down a procedure worth keeping — a multi-step process, a trap that cost real time, or something that has now come up three times. Use it the moment you finish such a task, while the details are still exact.

Record a change that reshaped the repository — what moved, why it was worth doing, and which areas it touched. Use after a migration, a rewrite, or a decision that changed how part of the system works.

Turn a scratch script into a permanent tool this repo keeps. Use when a check, report, or analysis has proved worth running more than once.

Rebuild the architecture index after files were added, removed, renamed, or restructured. Cheap to run; run it whenever the shape of the repo changed rather than waiting to be asked.

Record why something is the way it is — a decision and its reasoning, a lesson that cost time, or a standing constraint. Use when the reasoning behind a choice would be expensive to reconstruct later.

Show what this workspace has actually done to context cost in this repo — weekly context-per-turn, before and after. Use when the user asks whether chamnan is worth keeping.

Write down where this stretch of work stopped, so the next session continues instead of restarting. Use at the end of a working session, or when handing the repository to someone else.
