What it does

File Locate Verify is an agent skill from HKUDS/OpenSpace. Systematic workflow to resolve FileNotFoundError by locating and verifying file paths

Its SKILL.md is about 840 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.

The repository describes itself as: "OpenSpace: The Skill Management Layer for AI Agents" -- https://open-space.cloud/. The licence is MIT.

Example prompts

  • “/file-locate-verify”

Requirements

  • Python 3

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Check Current Directory Contents
  2. Search for the File Using Find
  3. Verify the Discovered Path
  4. Execute Your Operation Safely

What it can do on your machine

Read from SKILL.md and the folder at commit 3827781. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are python and bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

File Locate Verify loads about 837 tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 283 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~26
When it runs · the whole SKILL.md, loaded when a task matches
~837

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Systematic workflow to resolve FileNotFoundError by locating and verifying file paths

File Locate and Verify Workflow

When encountering FileNotFoundError or uncertain file paths, follow this systematic pattern to safely locate and verify files before executing operations.

When to Use

  • You receive a FileNotFoundError or similar path-related error
  • You need to work with files whose exact location is unknown
  • You want to verify file existence before executing operations that depend on those files

Step-by-Step Procedure

Step 1: Check Current Directory Contents

First, use list_dir to inspect what files exist in your current working directory:

python
# Use the list_dir tool to see current directory contents
list_dir(path=".")

This reveals files in the immediate context and helps determine if you need to search elsewhere.

Step 2: Search for the File Using Find

If the file is not in the current directory, use the find command to locate it by name:

bash
# Search for a specific file by name (case-insensitive)
find . -iname "filename.pdf" 2>/dev/null

# Or search from root for system-wide files
find / -name "filename.pdf" 2>/dev/null

Tips:

  • Use -iname for case-insensitive matching
  • Redirect stderr with 2>/dev/null to suppress permission errors
  • Narrow the search scope when possible for better performance
Step 3: Verify the Discovered Path

Before executing any operations on the discovered file, verify it exists and check its properties:

bash
# Verify file existence and permissions at the full path
ls -la /full/path/to/discovered/file.pdf

This confirms:

  • The file actually exists at the located path
  • File permissions (can you read/write it?)
  • File size and modification time
Step 4: Execute Your Operation Safely

Only after verification, proceed with your intended operation:

python
# Now safe to work with the verified path
file_path = "/full/path/to/discovered/file.pdf"
# ... your extraction or processing code here

Complete Example

python
# Task: Process a file that may be in an unknown location

# Step 1: Check current directory
dir_contents = list_dir(path=".")
print(f"Current directory contains: {dir_contents}")

# Step 2: Find the file if not present
if "target_file.xlsx" not in dir_contents:
    result = run_shell(command='find . -iname "target_file.xlsx" 2>/dev/null')
    file_path = result.stdout.strip().split('\n')[0]
    print(f"Found file at: {file_path}")

# Step 3: Verify before proceeding
verification = run_shell(command=f'ls -la {file_path}')
print(f"Verification: {verification.stdout}")

# Step 4: Proceed with operation
# ... your code to process the file

Common Pitfalls to Avoid

  1. Skipping verification: Never assume the path from find is correct without checking
  2. Using relative paths blindly: Always convert to absolute paths when possible
  3. Ignoring permissions: ls -la reveals if you have read/write access
  4. Hardcoding paths: Always dynamically locate files when location is uncertain
  • list_dir: Inspect directory contents
  • run_shell: Execute find and ls commands
  • read_file: Read file contents after verification
  • shell_agent: Delegate complex file operations after path is confirmed
