Pget

Parallel file download and optional tar extraction using the pget CLI (single URL or multifile manifest). Use when you need high‑throughput downloads from HTTP(S)/S3/GCS, want to split a large file into chunks for speed, or want to download and extract a .tar/.tar.gz in one step.

Security Scan

The skill is an instruction-only wrapper around the pget CLI; its requirements, instructions, and install references are consistent with the described parallel-download functionality and do not request unrelated credentials or access.

Purpose & Capability

The name/description match the provided instructions: everything focuses on downloading files (single or manifest) and optional tar extraction. No unrelated environment variables, binaries, or config paths are requested.

Instruction Scope

SKILL.md stays on-topic: it instructs how to run pget, how to supply a manifest or stdin, and how to tune concurrency and extraction. The only file reads referenced are user-supplied manifests or destinations necessary for download; there are no instructions to read unrelated system files or secrets.

Install Mechanism

references/pget.md includes installation commands that download a binary from GitHub releases and a Homebrew tap (replicate/pget). Those are expected for a CLI tool and are standard. Note: the curl install uses sudo to write to /usr/local/bin — running such install commands requires privilege and you should verify the release source and checksums before running.

Credentials

The skill requests no environment variables or credentials. Options like --resolve are CLI flags for pget and do not imply hidden credential access. The lack of secrets or config-path requirements is proportionate for a downloader tool.

Persistence & Privilege

The skill does not request always:true and is user-invocable. It does not attempt to modify other skills or system-wide settings. Autonomous model invocation is allowed (platform default) but not combined with any broad privileges here.

Assessment

This skill is an instruction-only wrapper for the pget CLI and looks internally consistent. Before installing or running the suggested curl command, verify the GitHub release/source (replicate/pget) and, if available, verify checksums or use Homebrew which is safer for macOS. Be aware that the "-x" in-memory extraction can consume large amounts of RAM for big archives, and manifest/STDIN input runs whatever URLs you provide — only download from trusted sources. If you plan to run install commands that write to /usr/local/bin with sudo, review the binary first or prefer a package manager.

Overview

Use pget for fast, parallel downloads and optional in‑memory tar extraction. Prefer it over curl/wget for large files or batch downloads.

Quick start

• Single file: pget <url> <dest>
• Extract tar after download: pget <url> <dest> -x
• Multi-file manifest: pget multifile <manifest-path> (or - for stdin)

Tasks

1) Download a single large file quickly

1. Choose destination path.
2. Run:

   pget <url> <dest>
   

3. Tune if needed:
   • --concurrency <n> to change chunk parallelism
   • --chunk-size 125M (or other size)
   • --retries <n>
   • --force to overwrite

2) Download and extract a tar archive

Use when the URL points to a .tar, .tar.gz, or similar.

pget <url> <dest> -x

This extracts in‑memory without writing the tar to disk first.

3) Download many files with a manifest

1. Create a manifest with URL + space + DEST per line.
2. Run:

   pget multifile /path/to/manifest.txt
   # or
   cat manifest.txt | pget multifile -
   

3. Tune:
   • --max-concurrent-files <n>
   • --max-conn-per-host <n>

Notes & pitfalls

• Use --force if the destination exists and you need overwrite.
• --connect-timeout accepts duration (e.g., 10s).
• --log-level debug or --verbose for troubleshooting.
