What it does
File Reading is an agent skill from Wide-Moat/open-computer-use. Use this skill when a file has been uploaded but its content is NOT in your context — only its path at /mnt/user-data/uploads/ is listed in an uploadedfiles block. This skill is a router: it tells you which tool to use for each file type (pdf, docx, xlsx, csv, json, images, archives, ebooks) so you read the right amount the right way instead of blindly running cat on a binary. Triggers: any mention of /mnt/user-data/uploads/, an uploadedfiles section, a filepath tag, or a user asking about an uploaded file you…
Its SKILL.md is about 3.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file. Compatibility notes: claude.ai, Claude Desktop, Cowork — any surface where uploads land at /mnt/user-data/uploads/
It sits in Documents & Office, covering Excel spreadsheets, Word documents and CSV and tabular files. It works with Microsoft Excel, Microsoft Word and Microsoft PowerPoint. The repository describes itself as: ARCHIVED — superseded by Wide Moat.
When your agent uses it
- Each file type (pdf
- Ebooks) so you read the right amount the right way instead of blindly running cat on a binary
- The file content is already visible in your context inside a documents block — you already have it
Example prompts
- “/file-reading”
Requirements
- Python 3
- Compatibility (from SKILL.md): claude.ai, Claude Desktop, Cowork — any surface where uploads land at /mnt/user-data/uploads/
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Look at the extension. That is your dispatch key.
- Stat before you read. Large files need sampling, not slurping.
- Read just enough to answer the user's question. If they asked
- If a dedicated skill exists, go read it. The table below tells
What it can do on your machine
Read from SKILL.md and the folder at commit 1ddf832. 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
Shell commands in SKILL.md call:
jqpdftotextpandoc
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.
Compatibility
claude.ai, Claude Desktop, Cowork — any surface where uploads land at /mnt/user-data/uploads/
From compatibility in the SKILL.md frontmatter.
Context cost
File Reading loads about 3.1k tokens when it runs. Until then it costs about 169 tokens; SKILL.md has 1,089 words of instructions outside code blocks.
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.
SKILL.md
Its licence (Proprietary) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,089 words (~3,141 tokens).
“When a user uploads a file in claude.ai, Claude Desktop, or Cowork, the file is written to /mnt/user-data/uploads/ and you are told the path in an block. The content is not in your context. You must go read it.”
