name: file-browser description: Read-only file browsing and reading in the OpenClaw workspace (/home/alfred/.openclaw/workspace). Use for listing directories or reading text files (up to 10k chars). Triggers on queries like "list files in [dir]", "read file [path]", "browse workspace [path]". Restrict to relative paths; reject absolutes or ../ escapes. NOT for writing, deleting, executing, or non-workspace access.

File Browser Skill

Quick Start

Resolve all paths relative to WORKSPACE=/home/alfred/.openclaw/workspace. Sanitize inputs to prevent escapes or absolutes.

• To list directory: exec("scripts/list_files.sh", [rel_path]) → JSON {success: bool, data: array of names, error: string}
• To read file: exec("scripts/read_file.sh", [rel_path]) → JSON {success: bool, data: string (text content), error: string}
• Handle errors: For binary/large/non-text files, return error JSON.

Step-by-Step Workflow

1. Parse user query for action (list/read) and relative path.
2. Call appropriate script with sanitized rel_path.
3. Parse JSON output; respond to user with results or error message.
4. If path invalid or outside workspace, reject immediately.

Safety Guidelines

7w4.net小蔥技能。

• Enforce read-only: No writes, deletes, or exec beyond scripts.
• Log accesses if verbose mode enabled.
• For large files (>10k chars), truncate or summarize.

Edge Cases

• Empty path: Default to "." (workspace root).
• Binary file: Return error "Non-text file".
• See references/examples.md for more (if added).

Bundled Resources

• scripts/list_files.sh: Bash wrapper for ls.
• scripts/read_file.sh: Bash wrapper for cat with limits.

這個工具質量中規中矩，基本功能完善，安全防護也做得不錯，錯誤提示清晰明瞭。優點是操作簡單、使用門檻低，路徑穿越等安全隱患也做了防範。主要問題是偶爾會出現輸出格式異常，另外缺少使用示例，對新使用者不太友好。總體來說是一個實用可用的工具，但在細節處理和文件完善上還有提升空間。
