File Ops Skill
Install this skill when you need directory management, batch copies,
moves/renames, or rich metadata beyond what the default file_* tools provide.
When to use which tool
- Create directory:
skill_file_ops_mkdir(path)— creates intermediate parents. - Copy:
skill_file_ops_cp(src, dest, recursive?)—recursivedefaults to true. - Move / rename:
skill_file_ops_mv(src, dest). - Rich metadata:
skill_file_ops_stat(path)— returns JSON{name,path,size,is_file,is_dir,is_image,mtime_ms,ctime_ms}. - Directory tree:
skill_file_ops_tree(path?, max_depth?)— recursive listing. - Check existence:
skill_file_ops_exists(path)— returns"true"or"false". - Touch:
skill_file_ops_touch(path)— create an empty file if missing.
POSIX file descriptor operations
For fine-grained I/O (seek, partial reads/writes, truncate), use execute_javascript
with the fs namespace directly:
let fd = await fs.open("log.txt", "a+");
await fs.write(fd, "new line\n");
await fs.seek(fd, 0, "start");
let head = await fs.read(fd, 100);
await fs.close(fd);
Open flags: "r", "r+", "w", "w+", "a", "a+" (Node-compatible).
Whence for seek: "start" | "current" | "end" (or 0 | 1 | 2).
File descriptors are scoped to a single execute_javascript call and
auto-closed when that call ends — but closing explicitly is good hygiene.
