Code Retro

Work that needed Corrections will need them again unless the environment changes. This skill finds the Corrections on one branch, traces each to what let it happen, and proposes the smallest Nudge that would have prevented it. It writes nothing except a report the user approves.

Announce at start: "I'm using the code-retro skill to look back at this branch."

A Correction is a human redirect the agent could have avoided using information it already had, or an error that escaped: a blocking review finding, validation or CI failing twice, or a fix commit after the PR opened. A Nudge is a small change to the environment that makes the desired behaviour the default. Judge by these, not by how annoyed the human sounded.
