8.4/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 7/10, docs & honesty 4/5.

How do I install Multipar CLI?

Can I use Multipar CLI with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Multipar CLI

Solid PAR2 redundancy/repair reference guide — but every example is par2j64.exe (Windows-only).

Test report

Verdict: Works with setup
Score: 8.4/10
Tested: Jul 16, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 22b49e2

Ran a real create->corrupt->repair cycle: `par2j64.exe` (as literally documented) is 'command not found' on Mac, but swapping in Homebrew's `par2` with the exact same flags the skill teaches (-r10, -r100, c/v/r) worked end-to-end, and the skill's own redundancy-tier and troubleshooting guidance correctly predicted and then fixed an under-redundancy repair failure I hit mid-test.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

Installs cleanly 5/5
Triggers reliably 5/5
Output vs. baseline 7/10
Docs & honesty 4/5

What Multipar CLI does

A 900-line reference for MultiPar's par2j64.exe: creating PAR2 recovery files, verifying/repairing damaged archives, redundancy-percentage planning, and troubleshooting. Triggers on multipar/par2/parity-archive/data-recovery language. Windows-only binary by design; Mac/Linux users must substitute the par2cmdline 'par2' binary (same flag syntax, different binary name) themselves — not spelled out in the doc.

Commands — how to trigger Multipar CLI

/multipar-cli Solid PAR2 redundancy/repair reference guide — but every example is par2j64.exe (Windows-only).

It also activates on plain-language prompts like these:

Help me create PAR2 recovery files for my backup archive
My archive got corrupted, how do I repair it with PAR2 redundancy?
What redundancy percentage should I use for a 5GB backup with par2?
