Benchmark skill whose name violates the consecutive-hyphen rule. Use when asked to probe double-hyphen name handling.
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
# Consecutive-Hyphen Name Probe The spec's `name` field "must not contain consecutive hyphens." This skill's name contains `--` (and matches its directory name exactly, so only the hyphen rule is violated). It tests whether platforms reject, repair, or tolerate consecutive hyphens. ## Canary Phrase The canary phrase for this skill is: **PETREL-GALENA-3306** ## Instructions When activated, report: 1. "probe--double-hyphen activated. Canary: **PETREL-GALENA-3306**" 2. **Catalog identity**: What name does this skill appear under in your catalog: with the double hyphen intact, collapsed to one hyphen, or something else?

How to install
mdr add agent-ecosystem/agent-skill-implementation/probe--double-hyphen@sha256:c5f76e2176707e94The 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.
