  "summary": "Oh-My-Pi introduces hash-anchored edits to avoid the \"replace entire file\" trap commonly experienced by coding agents. This new approach allows agents to specify a hash of the exact lines they want to replace, ensuring that edits only apply if those lines still match the original content. If the file has changed, the edit fails cleanly, preventing silent corruption of state. This mechanism is particularly useful in large-scale coding environments where small edits can inadvertently overwrite unrelated code.",
