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?) — recursive defaults 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.
