filesystem

1# Filesystem Skill
2 
3## Overview
4Direct filesystem operations without external dependencies. Read, write, edit, list, copy, move, and search files.
5 
6## Usage
7 
8Use the available builtin tools to perform file operations directly. Commonly used tools for this skill are: `list_dir`, `read_file`, `file_create`, `edit_file_by_lines`, `grep`, and `bash`.
9 
10When the task requires programmatic/structured processing (e.g., parsing complex formats or batch transformations), `python_repl` can be used as an advanced fallback.
11 
12- Paths can be absolute or relative to working_dir
13- Parent directories are created automatically for write operations
14- For complex file operations not covered by builtin tools, use `bash`

18## Common Recipes
19 
20### JSON
21 
22```python
23import json
24 
25# Read
26with open('data.json', 'r', encoding='utf-8') as f:
27    data = json.load(f)
28 
29# Write (pretty-printed)
30with open('output.json', 'w', encoding='utf-8') as f:
31    json.dump(data, f, indent=2, ensure_ascii=False)
32```
33 
34### CSV
35 
36```python
37import csv
38 
39# Read
40with open('data.csv', 'r', encoding='utf-8') as f:
41    reader = csv.DictReader(f)
42    for row in reader:
43        print(row)
44 
45# Write
46with open('output.csv', 'w', newline='', encoding='utf-8') as f:
47    writer = csv.DictWriter(f, fieldnames=['name', 'value'])
48    writer.writeheader()
49    writer.writerows([{'name': 'a', 'value': 1}])
50```
51 
52### YAML
53 
54```python
55# Requires: pip install pyyaml
56import yaml
57 
58# Read
59with open('config.yaml', 'r') as f:
60    data = yaml.safe_load(f)
