Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
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 | $0.00043 | $0.01536 |
| Opus 5 | $0.00022 | $0.00768 |
| Sonnet 5 | $0.00009 | $0.00307 |
| Haiku 4.5 | $0.00004 | $0.00154 |
Grade A, and why
motif-for-claude-science-skill 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Motif for Claude Science
Use this compatibility skill with the self-contained
motif-artifact.html file. New Claude/Cowork handoffs should prefer the
validated motif-for-claude-science.zip plugin bundle, which includes
an explicit file-generation helper.
Interaction boundary
The supported standalone workflow is:
- Build or receive the self-contained HTML file.
- Open it in a modern browser.
- Interact through its visible Inventory, Sequence, Map, and Tools controls.
The HTML defines window.motif* functions inside its own page. A skill does not
turn those browser globals into Cowork or Claude Code tools. Do not claim to
have called them unless the current session has a real browser bridge that can
evaluate JavaScript in the loaded page and the rendered result was verified.
When such a bridge is actually available, call window.motifHelp() in the page
context first. Treat that runtime manifest—not this file—as the source of truth
for current API names, schemas, restriction-source ids, examples, and return
values.
Prepare a preloaded artifact from source
From the Motif checkout:
npm run build:claude-science -- \
--payload ./motif-inventory.json \
--out ./motif-artifact.html
The default build is repo-local and writes the standalone HTML, standalone
skill, unpacked Claude plugin, deterministic plugin ZIP, and checksum manifest
under dist-motif/. Use --handoff <html-path> only when the user explicitly
wants a copy outside the checkout.
Minimal payload:
{
"schema": "motif.claude-science.inventory.v1",
"inventory": {
"title": "Example inventory",
"description": "Records prepared for review."
},
"records": [
{
"name": "Example insert",
"type": "dna",
"topology": "linear",
"group": "Design queue",
"sequence": "ATGGCCGCCGCC",
"features": [
{
"name": "coding insert",
"type": "cds",
"start": 0,
"end": 12,
"direction": "forward",
"color": "#2EAD67"

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.

motif-for-claude-science-skill is a skill published in the GitHub repository jvogan/motif (47 stars, last pushed yesterday), licensed MIT. It adds 43 tokens to every session and 1,536 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
