coder-file-transfer

coder-file-transfer is a skill for Claude Code from OneDro1d/dark-factory. It costs 116 tokens per session (932 once invoked), scanned A, original, Apache-2.0.

A file-transfer guide for moving large files, folders, build outputs, datasets, or binaries to and from a Coder workspace, which is a hosted development environment.

In plain words
What is it for?
Use it to configure an SSH connection and transfer files with GNU rsync, including resumable uploads and downloads.
Why use it?
It addresses unreliable or corrupted transfers when using the ordinary Coder SSH or rsync setup on macOS.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is rsync -avP -e "ssh -T" <workspace>.coder:/remote/dir ./local/target/.

Good fit Use it to configure an SSH connection and transfer files with GNU rsync, including resumable uploads and downloads.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

coder-file-transfer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Coder Workspace File Transfer

Move large files to (or from) a Coder Cloud Development Environment reliably. The naive path — rsync -e "coder ssh" — is broken on macOS. Use a coder config-ssh host alias with a protocol-clean, PTY-free SSH channel instead.

When to use

  • Uploading a directory, dataset, build artifact, or binary to a Coder workspace.
  • rsync -e "coder ssh" fails, desyncs mid-transfer, or hangs.
  • A copy over coder ssh corrupts or never completes.
  • You need a resumable transfer over a flaky dev tunnel.

The one-liner

coder config-ssh                                          # one-time per machine
rsync -avP -e "ssh -T" /local/dir <workspace>.coder:/remote/target/dir/

Instructions

  1. Generate SSH host aliases (one-time per machine/workspace):

    coder config-ssh
    

    This adds host entries to ~/.ssh/config. Note the alias for your workspace from the output — typically <workspace>.coder (e.g. workspace Loom → host Loom.coder).

  2. Confirm you have GNU rsync (macOS ships the incompatible openrsync):

    rsync --version
    

    If it says openrsync, install GNU rsync:

    brew install rsync
    
  3. Ensure the remote target directory exists:

    coder ssh <workspace> -- mkdir -p /remote/target/dir
    
  4. Transfer — preferred (resumable):

    rsync -avP -e "ssh -T" /local/dir <workspace>.coder:/remote/target/dir/
    
    • -a archive, -v verbose, -P = --partial --progressresumable.
    • -e "ssh -T" disables PTY allocation — the essential fix.
  5. Transfer — fallback (no resume):

    scp -r /local/dir <workspace>.coder:/remote/target/dir/
    
  6. Download (reverse direction) — swap the arguments:

    rsync -avP -e "ssh -T" <workspace>.coder:/remote/dir ./local/target/
    

What NOT to do

  • rsync -e "coder ssh" src host:dst — macOS openrsync desyncs against the remote GNU rsync; even with GNU rsync, coder ssh's PTY corrupts the byte stream.
  • ❌ Omitting -e "ssh -T" — the default TTY allocation breaks rsync/tar pipelines.
  • ❌ Trusting the macOS built-in rsync — always verify rsync --version reports GNU.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

coder-file-transfer is a skill published in the GitHub repository OneDro1d/dark-factory (0 stars, last pushed today), licensed Apache-2.0. It adds 116 tokens to every session and 932 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
