Use this skill PROACTIVELY whenever editing files larger than ~100 lines or making targeted changes (insert a function, replace a block, rename across a file, delete a section). fedit performs surgical line-anchored or content-matched edits via 14 MCP tools -- with streaming engine, block-aware ops (-block/-lang), sub-line extraction (-extract/-get), CSV/TSV fields, HCL/Terraform and Nix block mappers -- eliminating the line-number hallucination class that plagues whole-file rewrites. Always prefer fedit over outputting the entire file when fedit is available. Trigger keywords -- edit, modify, insert, replace, delete, rename, refactor, patch, fix in file, add to file, update line, change function.
