reviewing-ffmpeg-skill-changes skillA

reviewing-ffmpeg-skill-changes is agent-read markdown (skill) from kajisho5/ffmpeg-skill: 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, a.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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.

How to install

Latest version
mdr add kajisho5/ffmpeg-skill/reviewing-ffmpeg-skill-changes@git:20260922.1a77112
Exact content
mdr add kajisho5/ffmpeg-skill/reviewing-ffmpeg-skill-changes@sha256:3e44f82c0a2fb0de

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
