Run the CI gate on your machine so it agrees with the runner — deriving the exact command, paths, markers, and env from the workflow file instead of the Makefile, unblocking gate steps that short-circuit and hide the next failure, pinning the linter version CI resolves, building the interpreter/toolchain environment the runner builds, and confirming the run is green instead of explaining a red job away. Use when a check passes locally but fails in CI (or the reverse), when a lint/format job…

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

# Reproducing CI Locally

A local check is only useful if it runs the same thing the runner runs. Most
"green locally, red in CI" failures are not bugs in the code — they are a
difference between two commands: different paths, different test markers,
different env, a different linter version, or a different interpreter.

The fix is mechanical: **derive the local command from the workflow file**, not
from the Makefile, not from habit, not from what the last repo used.

## Read the workflow before you run anything

The workflow is the contract. The Makefile is a convenience that drifts from it.

```bash
# What the gate actually is, in order
sed -n '/jobs:/,$p' .github/workflows/ci.yml

# Every command CI runs, across all workflows
grep -rn "run:" .github/workflows/
```

Copy out four things, verbatim:

1. **The commands and their order.**
2. **The paths each command is scoped to** (`ruff check app tests scripts` is not
   `ruff check .`).
3. **Test selection** — marker expressions, `-k` filters, which suites are excluded.
4. **The `env:` block**, and the runtime/toolchain versions in `setup-*` steps.

Each of those four is a distinct way to get a wrong answer locally.

How to install

The exact contents, by fingerprint
mdr add kajisho5/ffmpeg-skill/reproducing-ci-locally@sha256:ace4670d4720f565

The line at the top of this page pins the label git:20260906.24c1610, 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.
