Run any installed skill on several models at once — you, OpenAI Codex, OpenCode and whoever else the profile names — and show what each one made of it side by side. Every model gets the same prepared copy of the skill and works read-only. Use for "/multi:skill <name>", "run this skill on every model", "run <skill> through multi", or any skill whose answer you want from more than one model.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Run a skill on several models
!`"${CLAUDE_SKILL_DIR}/../../scripts/probe.sh"`
A skill is a set of instructions. Every harness reads the same SKILL.md format
(agentskills.io), so every model can follow it — what differs is what each one
makes of it. This skill hands one prepared copy of the named skill to every
participant and shows the answers next to each other. No judge, no merged
report: the user reads them and picks.
`$SCRIPTS` is whatever the probe printed as `scripts-dir:`.
**On any host other than Claude Code** the line above is plain text, nothing
ran. Your first step is then to run the probe yourself and read its output as
if it were printed here: `<dir of this SKILL.md>/../../scripts/probe.sh` — the
plugin's `scripts/probe.sh`, two directories above the *real* file (resolve
symlinks first: `realpath` of this SKILL.md, then `../../scripts/probe.sh`).
If the line above reads `Shell substitution failed` instead of probe output,
the session is in a git worktree whose shell gate refused the header; the
plugin is fine. Run `"${CLAUDE_SKILL_DIR}/../../scripts/probe.sh"` yourself,
as one plain command with nothing but the path, and read `scripts-dir:` from
that.
…Read the whole file at its exact version.
How to install
mdr add szarkans/multi/skill@sha256:6883062ae5513037The line at the top of this page pins the label git:20261008.796b10f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
