code-transfer
Transfer code between files with line-based precision. Use when users request copying code from one location to another, moving functions or classes between files, extracting code blocks, or inserting code at specific line numbers.
npx skills add mhattingpete/claude-skills-marketplace --skill code-transfer --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Code Transfer Transfer code between files with precise line-based control. **Dual-mode operation**: native tools (1-10 files) or execution mode (10+ files, 90% token savings). ## Operation Modes ### Basic Mode (Default) Use Read, Edit, Bash scripts for 1-10 file operations. Works immediately, no setup required. ### Execution Mode (10+ files) ```python from api.filesystem import batch_copy from api.code_analysis import find_functions functions = find_functions('app.py', pattern='handle_.*') operations = [{ 'source_file': 'app.py', 'start_line': f['start_line'], 'end_line': f['end_line'], 'target_file': 'handlers.py', 'target_line': -1 } for f in functions] batch_copy(operations) ``` ## When to Use - "copy this code to [file]" - "move [function/class] to [file]" - "extract this to a new file" - "insert at line [number]" - "reorganize into separate files" ## Core Operations ### 1. Extract Source Code ``` Read(file_path="src/auth.py") # Full file Read(file_path="src/auth.py", offset=10, limit=20) # Line range Grep(pattern="def authenticate", -n=true, -A=10) # Find function ``` ### 2. Insert at Specific Line Use `line_insert.py` script for line-based insertion: ```bash python3 skills/

What does the code-transfer skill do?
Transfer code between files with line-based precision. Use when users request copying code from one location to another, moving functions or classes between files, extracting code blocks, or inserting code at specific line numbers.
How do I install it?
Run `npx skills add mhattingpete/claude-skills-marketplace --skill code-transfer --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From mhattingpete/claude-skills-marketplace, a repository with 656 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
