Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00101 | $0.03272 |
| Opus 5.5 | $0.00040 | $0.01309 |
| Sonnet 5.5 | $0.00020 | $0.00654 |
| Haiku 4.5 | $0.00010 | $0.00327 |
Grade A, and why
analyze scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
92% identical to motiscope-analyze — 64 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 191 lines — stays where its author put it; the contents beside it link to each section on GitHub.
motiscope: analyze
Turn a screen recording of an animation into a precise, target-agnostic animation spec you can hand to /motiscope:recreate. A bundled Python pipeline measures the motion (a dense per-frame motion-energy curve + ffmpeg signal analysis — this is the source of truth for timing and easing) and extracts a small set of curated PNG keyframes for you to see. You combine the two into the spec.
Resolve the scripts directory (do this first)
Every command below runs a bundled script. Set SCRIPTS:
SCRIPTS="${CLAUDE_PLUGIN_ROOT:-}/scripts"
# Fallback for harnesses that don't export CLAUDE_PLUGIN_ROOT: this SKILL.md lives at
# <plugin>/skills/analyze/SKILL.md, so scripts are two levels up. Use the absolute
# path of the directory containing the SKILL.md you just Read.
if [ ! -f "$SCRIPTS/ingest.py" ]; then
SCRIPTS="<absolute dir of this SKILL.md>/../../scripts"
fi
if [ ! -f "$SCRIPTS/ingest.py" ]; then
echo "ERROR: cannot find ingest.py — check the plugin install." >&2; exit 1
fi
On Windows use python instead of python3 in every command below.
Step 0 — preflight (silent on success)
python3 "$SCRIPTS/mvsetup.py" --check
Exit 0 → proceed silently. Non-zero → ffmpeg/ffprobe are missing; hand off to /motiscope:doctor (don't try to analyze without them).
Step 1 — resolve the input video
- If the user gave a path (in
$1or their message), use it. - Otherwise scan the drop folder and project root:
ls -t animations/*.{mp4,mov,webm,mkv,m4v,avi,gif} *.{mp4,mov,webm,mkv,m4v,avi,gif} 2>/dev/null | head- Several candidates → ask the user (
AskUserQuestion) which one. - Exactly one → use it.
- None → tell the user to drop a recording into
animations/(or pass a path) and stop.
- Several candidates → ask the user (
Local files only. motiscope does not download URLs. If the user pastes a URL, ask them to screen-record it and drop the file in.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

analyze is a skill published in the GitHub repository KumarSashank/motiscope (129 stars, last pushed 3mo ago), licensed MIT. It adds 101 tokens to every session and 3,272 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 92% identical to motiscope-analyze, differing in 64 lines, and is treated as a copy.
