media-spec-checker from jqaisystems/jqai-ai-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add jqaisystems/jqai-ai-skills/media-spec-checker@git:20261014.c1a6454Pins git:20261014.c1a6454 in mdr.lock. Pin the fingerprint instead.

Check local image and video files against explicit technical requirements and produce measured pass, fail, or unverified results. Use for delivery-format checks, media-folder QA, dimensions, display ratios, duration, codecs, file sizes, or naming checks, not creative scoring or automatic conversion.
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
# Media Spec Checker
Turn a supplied delivery specification into reproducible checks without changing the media.
## Workflow
1. Identify the exact local files and intended delivery requirements. Do not infer current platform limits from memory.
2. Read [the rules contract](references/rules-contract.md). Adapt [the fictional profile](assets/example-rules.json) to the supplied specification. Omitted checks are not performed.
3. Run the helper, using a finite timeout:
python scripts/check_media.py sample-media --rules rules.json --recursive --json
4. Explain each failure and each unverified measurement. Missing tools, malformed media, unsupported files, absent durations, or an unconfigured media type are not passes.
5. Return measured values, the requirements used, the report counts, and the smallest suggested correction. Do not convert or alter files unless a separate task authorizes it.
## Dependencies and limits
…Read the whole file at its exact version.
How to install
mdr add jqaisystems/jqai-ai-skills/media-spec-checker@sha256:120cb71ae0213f95The line at the top of this page pins the label git:20261014.c1a6454, 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.
