The Atlas series — prompt skills that keep AI agents honest about the goal. atlas-contract freezes tasks into auditable Goal Contracts and stops before silent drift; atlas-ledger compounds caught drift into project-local rules. Works with Codex, Claude, Cursor.

Companion to atlas-contract. Auto-invoked by its Final Audit on caught drift; also use after Post Reviews or user requests to record a mistake. Distills drift into WHEN/DON'T/INSTEAD clauses, writes to Atlas.md after confirmation.
