msx-observation-rows SKILL.md skillA
msx-observation-rows from jeong-sik/masc is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Read selected MSX frames and input history from existing Lane observation rows with their machine incarnation, source coverage, and original evidence.
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
Use this skill when a task needs an explanation of existing MSX observations. It supplies an interpretation procedure and an optional local helper. Choose whether that evidence is useful to the current task. 1. Inspect the existing Lane rows and select exact row IDs. Keep the installation, instance, observation sequence, machine incarnation, and clock domain together. 2. Read `references/observations.md` through `keeper_skill` using this skill's exact reference and `file`. Separate a captured frame from a game turn or a strategic outcome, and report incomplete source coverage with the observation. 3. For a compact projection, optionally read `scripts/summarize.py` through the same resource reader. Save the returned bytes in an already authorized workspace if execution is useful. The reader returns bytes and their SHA-256; it does not run the script or make the package's host path available in a Keeper sandbox. 4. The helper accepts one `rows`/`coverage` JSON document on stdin and exact `--row-id` arguments. It prints selected capture coordinates and evidence references. Use the existing execution tools and their current controls to run …

How to install
mdr add jeong-sik/masc/msx-observation-rows@sha256:694977a41a79ddefThe line at the top of this page pins the label git:20260915.0b8fe85, 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.
