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 | $0.00075 | $0.04099 |
| Opus 5 | $0.00037 | $0.02049 |
| Sonnet 5 | $0.00015 | $0.00820 |
| Haiku 4.5 | $0.00007 | $0.00410 |
Grade A, and why
minimax-h3-video 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 8d 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 — 274 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MiniMax H3 (Hailuo) — local video
This skill teaches the local-weights MiniMax H3 path in ComfyUI. It is the
pilot for #1155 (Official vs Empirical sources) because MiniMax publishes a
real prompting guide. Cite that guide by URL. Do not copy it into this repo.
Two products, two cost models — pick one
They share a brand and must not be mixed.
| Path | Nodes | Cost | VRAM | When |
|---|---|---|---|---|
| Local weights (this skill) | MiniMaxH3ImageToVideo, MiniMaxH3ReferenceToVideo, EmptyMiniMaxH3LatentAV, MiniMaxH3SigmaShift, MiniMaxH3MemoryEfficientSageAttentionPatch |
Free after download | Yes — INT8 + turbo LoRA is the 8 GB story | User wants 4–15 s stereo clips on their GPU |
| Partner API | MinimaxHailuo03TextToVideoNode, MinimaxHailuo03FirstLastFrameNode, MinimaxHailuo03ReferenceNode, MinimaxTextToVideoNode, MinimaxImageToVideoNode, MinimaxHailuoVideoNode |
Paid per generation | None | User has a MiniMax / Hailuo API key and does not want local weights |
API nodes do not take MiniMaxH3SigmaShift or Sage-attention patches. Local
nodes do not spend API credits. If the user asked for Hailuo cloud, stop and
use the API nodes + their key; do not download 40 GB of weights.
MiniMaxH3Director is a third-party pack (muse-collective-26/MiniMaxH3-Director),
not core. Do not require it for T2V / I2V / R2V.
License — cite, do not copy
Local weights and MiniMax's own documentation sit under the
MiniMax H3 Community License.
Materials includes the Documentation. The agreement's Applicable Territory
excludes the United States, the EU, the UK, and South Korea. This skill
does not reproduce MiniMax's skills/h3-prompt-writing/ SKILL.md or the
prompting-guide prose. Linking to a public URL is the #1155 requirement.
This is not legal advice. Tell a US/EU/UK/KR user that the local path is territory-restricted and that the paid API is a separate product under MiniMax platform terms.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

minimax-h3-video is a skill published in the GitHub repository artokun/comfyui-mcp (740 stars, last pushed 2d ago), licensed MIT. It adds 75 tokens to every session and 4,099 once invoked, about $0.0004 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.
