run-scenario SKILL.md skillB
run-scenario from using-system/oddyssey is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add using-system/oddyssey/run-scenario@git:20260914.60f6a52Pins git:20260914.60f6a52 in mdr.lock. Pin the fingerprint instead.

Drive a reproducible request scenario against a locally running service - ad-hoc requests, or a stored k6 benchmark from .odd/benchmarks/ - and record it verbatim, so the telemetry it produces can be compared with a later run. Use when traffic must be generated before observing a service, when a stored k6 benchmark must be run, when an observation report needs a replayable scenario, or when verifying after a fix that the same scenario now measures better.
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 Scenario One protocol on both ends of the ODD loop: the same commands that produced the numbers in an observation report produce the numbers that verify the fix. A scenario that cannot be replayed verbatim makes before/after comparison an impression, not a measurement. **A step this package ships a script for is run, never rewritten.** The ad-hoc drive is this skill's `scripts/drive_scenario.py` (step 2); a stored benchmark's replay is `k6-guides`' `scripts/replay_benchmark.py` (`references/benchmark-replay.md`). A curl loop, a helper with a `sleep` in it, a poller written for either yields a different command each time — two runs then measure two things. ## Read by situation Steps 1 to 5 and the rules are the method; a reference is read by the block that applies, never whole: | Situation | Reference | | --- | --- | …

How to install
mdr add using-system/oddyssey/run-scenario@sha256:436fe6175abdbdf0The line at the top of this page pins the label git:20260914.60f6a52, 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.
