CodeSmith How Ledgers and Snapshots Cure AI Debt
Ledger and Snapshots: The Debt AI Owes and the Regret Medicine Left for You Source version of CodeSmith : v0.5.0 (commit 3a74c82f ). All paths are relative to the repo root; line numbers refer to this version. Intended audience: readers who have inherited a module that AI refactored, or who in the middle of the night wanted to roll back but had no idea which step to roll back to. Start with two…
Debt AI Owes and the Regret Medicine Left for You: CodeSmith introduces two mechanisms to address AI's technical debt - the Slop Ledger and side-git snapshots. The Slop Ledger, a JSON file named ~/.codesmith/slop_ledger.json, registers AI's invisible "slop" or technical residue, including compatibility shims, unmigrated callers, duplicated concepts, and more.
It classifies the slop into ten categories, such as retained compatibility, unmigrated callers, suspected dead code, and tool gaps. Each SlopEntry records classification, severity, confidence, owner, source links, title, description, lifecycle status, cleanup recommendation, timestamps, and an optional linked task ID. The ledger includes four tools: append, query, update, and export.
The export produces a redacted Markdown document suitable for GitHub issues or compacting the ledger. This design is unique because most AI coding tools focus on optimizing the work process, but they don't handle post-work residue. AI agents lack memory across sessions, and the next AI agent is a stranger, making it difficult to understand previous decisions.
The ledger helps prevent the accumulation of unrecognized and unaddressed AI residue, which can lead to unexpected changes and architectural drift.
