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.

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 | $0.00170 | $0.01600 |
| Opus 5.5 | $0.00068 | $0.00640 |
| Sonnet 5.5 | $0.00034 | $0.00320 |
| Haiku 4.5 | $0.00017 | $0.00160 |
Grade A, and why
modellix-social-card 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 5d 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 — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Modellix Social Card
Turn a note, article, or announcement into prompts for social cards. This skill
plans the cards. modellix-design generates them.
Do not submit, poll, download, authenticate, or inspect model schemas here. Do not
run the Modellix CLI. Do not recommend a model, a provider, or a slug. Catalogs
change quickly, and choosing a model is outside this skill. When the user wants
the images made, finish the brief first and then hand each prompt to
modellix-design.
A cover, thumbnail, or carousel for a named network stays here. A set of
illustrations placed through an article, with no named network, belongs to
modellix-article-illustrator. A structured infographic belongs to
modellix-infographic. A poster, product shot, or illustration that is not an
information diagram belongs to modellix-image-prompt-engineering. Files already
on disk belong to modellix-ffmpeg or modellix-moviepy.
Route the request
Use this skill when the user wants a card, cover, thumbnail, or carousel for a specific network, or when the wording is "social post image" even if they have not named the network yet.
Skip or keep the pass short when:
- The user already supplied a finished prompt and asked only to run it. Pass that
prompt to
modellix-design. - The request is an article, blog, or newsletter cover and does not name a
network placement. Use
modellix-cover-image. - The request is a set of illustrations placed through an article and does not
name a network placement. Use
modellix-article-illustrator. - The request is a knowledge comic, educational comic, biography comic, or
four-panel strip, and does not name a network placement. Use
modellix-comic. - The request is a poster or illustration with no platform. Use
modellix-image-prompt-engineering. - The request is a structured infographic. Use
modellix-infographic. - The request is a commerce UGC video that still needs a shot plan. Use
modellix-ecomm-ugc-video. - The request is video editing, subtitles, credentials, task status, or a download.
- The user wants an avatar or a profile banner. Say those placements are outside this skill and ask which content card they want instead.
What ships with it

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.
