Shrink a media asset to the smallest bytes that still serve its purpose, keyed on asset kind (raster, vector, animation, video, audio, model, document, font) and on where it will be presented. Detects and acquires the right binary from a central tool manifest, runs a lossless-or-lossy pass decided by fidelity intent, measures before and after, validates the output, and keeps the result only if it is smaller AND still valid, redirecting to a better format or a different kind when the source is…
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
# Asset Optimization > The smallest asset that still serves its purpose. Measure the bytes, not the intent. An asset is a media file whose bytes we shrink without changing what it is for. This skill is a lookup keyed on the asset's **kind** that decides format, tool, and whether the pass may lose information, so the file ends up as small as it can be while still doing its job on the surface it will be presented on. **Structure.** Each kind is an executor under `executors/<kind>/`, a folder of standardized organs: `procedure.md` (the how-to, including prerequisites and cross-kind redirects), `cookbook.md` (curated verbatim recipes), `targets.md` (surface to format), and `expectations.md` (measured size data). The cross-cutting references at the root are [`tools.md`](tools.md) (the tool manifest, defined once because one tool serves many kinds), [`surface.md`](surface.md) (which surface), [`classify.md`](classify.md) (how to detect a file's kind), [`batch.md`](batch.md) (repository operation, originals, idempotence, report), and [`cookbook.md`](cookbook.md) (the recipe rubric and an index of every kind's cookbook).

How to install
mdr add simiancraft/simiancraft-skills/asset-optimization@sha256:8581fe0a15640047The line at the top of this page pins the label git:20260702.1f505b1, 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.
