Generative-Media-Skills is a toolkit that lets AI agents generate, edit, and display images, videos, and audio through the muapi command-line interface. It is for users of Claude Code, Cursor, Gemini CLI, and OpenCode who need multimodal media-generation workflows. The catalogue entries are the skills that expose these media capabilities to coding agents.
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.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00026 | $0.00705 |
| Opus 5 | $0.00013 | $0.00352 |
| Sonnet 5 | $0.00005 | $0.00141 |
| Haiku 4.5 | $0.00003 | $0.00071 |
Grade B, and why
muapi-instagram-post scanned grade B with 2 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 11d 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.
Sends data to an external URLmediumData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.
- For model IDs without a CLI alias yet, fall back to the raw endpoint via `curl -X POST https://api.muapi.ai/api/v1/<endpoint> -H "x-api-key: $MUAPI_API_KEY" -H 'content-type: application/json' -d '{...}'` and poll with Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

Instagram Post
Create a polished, on-brand Instagram post — square or portrait hero image with matching caption and hashtags.
Inputs
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
brief |
text | yes | — | What the post is about (e.g. "summer coffee launch at our café, warm golden vibes"). |
brand_style |
text | no | modern, vibrant, clean typography, lifestyle photography aesthetic | Brand personality and visual style tags. |
format |
text | no | 1:1 | Post format — "1:1" for feed square, "4:5" for portrait feed, "9:16" for Reels. |
Steps
This skill produces one polished Instagram-ready visual + caption. Use the plan if generating more than one variant.
Phase A — Generate the hero image
- Write a detailed, atmosphere-rich image prompt based on
{{brief}}and{{brand_style}}:- Include lighting direction, color palette, mood, subject placement, and lens feel.
- Optimize for Instagram aesthetics: clean, punchy, single focal point.
- Append style tags:
{{brand_style}}, social media photography, highly detailed.
- Call
muapi image generate(model=nano-banana-2, aspect_ratio={{format}}). - If the user provided a product or subject image in the session, prefer
muapi image editinstead to maintain visual consistency.
Phase B — Caption & Hashtags
After the image is generated, compose and return:
- Caption: 2–4 lines. Hook line first (punchy, curiosity-driving), then brand message, then CTA.
- Hashtags: 15–20 targeted hashtags (mix of niche, mid-tier, and broad). Format as a separate block.
Notes
- Prioritize scroll-stopping first impressions — the image must visually communicate the brief within 2 seconds.
- If
formatis9:16(Reels cover), note that text overlays are common; include a suggestion for on-screen text placement. - Do NOT generate multiple variants unless the user explicitly asks.

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.

muapi-instagram-post is a skill published in the GitHub repository SamurAIGPT/Generative-Media-Skills (4,259 stars, last pushed 2d ago), licensed MIT. It adds 26 tokens to every session and 705 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
