What it does

Locate Missing Artifacts is an agent skill from HKUDS/OpenSpace. Recover generated files in sandboxed environments by searching from confirmed roots and copying to expected locations

Its SKILL.md is about 1k 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

  • “/locate-missing-artifacts”

Workflow steps

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

  1. Confirm the Failure
  2. Identify Confirmed Root Directories
  3. Search for the Artifact Using find
  4. Copy Artifact to Expected Location
  5. Validate Before Proceeding

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 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

Locate Missing Artifacts loads about 1k tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 273 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~36
When it runs · the whole SKILL.md, loaded when a task matches
~1k

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.

Recover generated files in sandboxed environments by searching from confirmed roots and copying to expected locations

Locate Missing Artifacts in Sandboxed Environments

When to Use This Skill

Use this skill when:

  • A tool reports success but files are not found in their expected locations
  • You receive errors like "file not found" after a tool claims to have created it
  • You're working in a sandboxed/ephemeral environment where file paths may shift
  • Directory structure mismatches occur between tool execution and validation

Step-by-Step Instructions

Step 1: Confirm the Failure

Before searching, verify the file is actually missing from the expected location:

bash
ls -la /expected/path/filename.ext
# or
test -f /expected/path/filename.ext && echo "Found" || echo "Missing"
Step 2: Identify Confirmed Root Directories

Determine which directories you know exist and where tools typically write:

bash
# Common roots to check
ls -la /
ls -la $HOME
ls -la /tmp
ls -la /workspace
ls -la .
Step 3: Search for the Artifact Using find

Use find from confirmed root directories to locate the missing file:

bash
# Search by filename
find /workspace -name "filename.ext" 2>/dev/null

# Search by pattern if exact name varies
find /workspace -name "*.ext" 2>/dev/null

# Search broader paths if needed
find / -name "filename.ext" 2>/dev/null | head -20
Step 4: Copy Artifact to Expected Location

Once located, explicitly copy the file to where it should be:

bash
# Copy to expected location
cp /found/path/filename.ext /expected/path/filename.ext

# Or if you need to preserve the original
cp -r /found/path/filename.ext /expected/path/

# Verify the copy succeeded
ls -la /expected/path/filename.ext
Step 5: Validate Before Proceeding

Confirm the file is now accessible at the expected location:

bash
# Test file exists and is readable
test -f /expected/path/filename.ext && test -r /expected/path/filename.ext && echo "Ready"

# Check file size to ensure it's not empty
stat /expected/path/filename.ext

Common Patterns

Pattern: Output Written to Wrong Directory
bash
# Tool wrote to current directory instead of specified output dir
find . -name "*.docx" -type f
cp ./report.docx ./output/report.docx
Pattern: Temporary Directory Used
bash
# File ended up in /tmp or similar
find /tmp -name "*.pdf" -mtime -1
cp /tmp/generated.pdf ./deliverables/
Pattern: Nested Subdirectory Created
bash
# Tool created extra directory levels
find /workspace -type f -name "*.xlsx"
# May find: /workspace/output/2024/reports/file.xlsx
cp /workspace/output/2024/reports/file.xlsx /workspace/deliverables/

Prevention Tips

  1. Always specify absolute paths when giving tools output locations
  2. Check the working directory before and after tool execution: pwd
  3. Verify immediately after a tool reports success before proceeding
  4. Use tool-specific confirmations when available (e.g., return paths)

Example: Complete Recovery Workflow

bash
# 1. Tool reported creating report.docx but it's missing
ls ./deliverables/report.docx
# Output: ls: cannot access './deliverables/report.docx': No such file or directory

# 2. Search for it
find /workspace -name "report.docx" 2>/dev/null
# Output: /workspace/tmp/generated/report.docx

# 3. Copy to expected location
mkdir -p ./deliverables
cp /workspace/tmp/generated/report.docx ./deliverables/report.docx

# 4. Validate
ls -la ./deliverables/report.docx
# Output: -rw-r--r-- 1 user user 45678 Jan 15 10:30 ./deliverables/report.docx

# Success - file is now where it should be

Troubleshooting

ProblemSolution
find returns no resultsExpand search to broader paths (/, /home, /root)
Multiple matches foundCheck timestamps (-mtime -1) or file sizes to identify the correct one
Permission denied on copyUse sudo if available, or check if file is in a read-only mount
File exists but is emptyThe tool may have failed silently; regenerate the artifact
