probe-script-execution from agent-ecosystem/agent-skill-implementation is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Benchmark skill for testing whether bundled scripts are executable. Use when asked to probe script execution behavior.
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
# Script Execution Probe The spec says the `scripts/` directory "contains executable code that agents can run." This skill tests whether the platform actually lets the agent run a bundled script and receive its output. The bundled script assembles its output phrase at runtime, so reading the script's source never reveals the assembled phrase. Only genuine execution produces it. ## Canary Phrase The canary phrase for this skill's body is: **REDSHANK-SYENITE-8807** ## Instructions When activated: 1. Report: "probe-script-execution activated. Canary: **REDSHANK-SYENITE-8807**" 2. Run the bundled script `scripts/emit-canary.sh`. Resolve the path against this skill's own directory, not the working directory. Use the bash interpreter if direct execution is not permitted. 3. Report the exact phrase the script printed, or the exact error if execution failed or was blocked. Do not guess the phrase; only report what the script actually printed.

How to install
mdr add agent-ecosystem/agent-skill-implementation/probe-script-execution@sha256:57136cb50109e780The line at the top of this page pins the label git:20260801.688ea1a, 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.
