dsh-copy-tool

When refactoring large projects with the write tool, AI models frequently drop lines, oversimplify complex logic, and produce incomplete patches that cost extra tokens and rounds of修补. dsh-copy-tool turns "move these exact lines there" from a vague context reproduction into a deterministic, line-number-driven operation: you specify which lines go where, and it migrates them verbatim—no more, no less.\n\nUnder the hood, a single call can mix discrete lines and continuous ranges (e.g. [633, [640, 645], 700]) with source lines and target lines mapped positionally; it detects and strips the common indentation across all selected non-empty lines, then re-applies a clean four-space indent level via the indent parameter. A dry_run pass emits a bounded unified diff for review before anything touches the filesystem. Creating a missing file and editing an existing one (including the source file itself) are both atomic operations that preserve untouched content and filesystem-native line endings, with every path resolved relative to the current session workspace and governed by its sandbox policy.\n\nIf you are splitting modules, relocating functions across files, or batch-adjusting indent levels inside DSH—or simply want your model to spend tokens on logical decisions instead of re-typing code—this plugin makes line-level copying a previewable, auditable, and reversible operation that significantly cuts the rework caused by omissions and oversimplification.
