* Improve tool descriptions to guide proper file editing tool selection ### Problem LLMs were frequently choosing `write_to_file` for file edits instead of more appropriate tools like `apply_diff`, `insert_content`, or `search_and_replace`. This was likely because the tool descriptions made it seem like files needed to be reconstructed rather than edited. ### Changes Made **write_to_file tool description:** - Clarified primary use cases: **creating new files** or **complete rewrites when intentionally required** - Changed opening from "write full content" to "write content" to reduce emphasis on full reconstruction - Updated parameter description to be more specific about when complete content is needed **apply_diff tool description:** - Enhanced description to emphasize "targeted modifications" and "precise, surgical edits" - Clarified that multiple search/replace operations can be performed in a single call - Removed misleading "only a single operation allowed" restriction - Better positioned as the preferred tool for making several targeted changes efficiently ### Impact These changes should guide LLMs toward: - Using `write_to_file` primarily for new files or intentional complete rewrites - Using `apply_diff` for targeted edits and modifications to existing files - Better understanding of when each tool is most appropriate The updated descriptions maintain necessary technical details while providing clearer guidance on tool selection without being overly prescriptive. * Update src/core/prompts/tools/write-to-file.ts Co-authored-by: ellipsis-dev[bot] <65095814+ellipsis-dev[bot]@users.noreply.github.com> * Update src/core/prompts/tools/write-to-file.ts Co-authored-by: Matt Rubens <mrubens@users.noreply.github.com> * Update src/core/prompts/tools/write-to-file.ts Co-authored-by: Matt Rubens <mrubens@users.noreply.github.com> --------- Co-authored-by: ellipsis-dev[bot] <65095814+ellipsis-dev[bot]@users.noreply.github.com> Co-authored-by: Matt Rubens <mrubens@users.noreply.github.com> |
