Review a change to the ffmpeg-skill repository for the failures its own contract makes possible — a claim in a result document that is true at one layer and false at the layer a caller reads, a new flag that reaches the code but not the contract/docs/demo surfaces, a "bug" that docs/design-decisions.md already decided with a pinning test, a fix with no regression test, a new runtime dependency or a raw ffmpeg shell call that breaks the scope boundary, a SKILL.md line added without one trimmed…

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

# Reviewing ffmpeg-skill Changes

This repository has an unusual failure mode, and a review that misses it looks
thorough while catching nothing. The product is a **JSON result document** that an
agent reads instead of watching the video. A change can be correct at the FFmpeg
layer, correct at the Python layer, and still ship a lie at the layer that
matters: `status: "completed"` next to a non-zero exit, `verified: true` for
something the tool never measured, a cut described as lossless when the keyframe
snap moved it 1.24 s. The 0.9.1/0.10.0 "honesty fix" (`cut.py`'s `mode` /
`keyframe_snapped` / `duration_delta_seconds`, `check.py`'s `reason`, `render.py`'s
check-stage exit code) exists because three such claims shipped and were caught
after the fact. **Review the claim, not just the code.**

The second failure mode is re-reporting decisions. Three review rounds on
2026-09-12 re-reported entries in `docs/design-decisions.md`, which is why that
file exists.

## Establish the review base first

Read the tree at the commit under review, not a summary of it and not your own
working copy if it has moved.

```bash
git fetch origin && git log --oneline -1 origin/main

How to install

The exact contents, by fingerprint
mdr add kajisho5/ffmpeg-skill/reviewing-ffmpeg-skill-changes@sha256:c38d78a73b82b81a

The line at the top of this page pins the label git:20261031.1dc2f52, 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.
