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.

SkillSpector: 1 finding, up to medium
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 →
- medium Excessive Agency · line 51 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00108 | $0.01910 |
| Opus 5 | $0.00054 | $0.00955 |
| Sonnet 5 | $0.00022 | $0.00382 |
| Haiku 4.5 | $0.00011 | $0.00191 |
Grade A, and why
minimax-h3-keyframe-video-prompt 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 13d 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 — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MiniMax H3 Keyframe Video Prompt
Design a continuous visual path from or toward concrete boundary frames. Treat a boundary image as an actual target frame, not merely a loose style reference.
Routing Contract
New MiniMax H3 requests should enter through minimax-h3-creative-director. Use this skill only for explicitly declared boundary-only images. If the user did not explicitly say first frame, last frame, starting frame, ending frame, or an equivalent literal boundary role, use minimax-h3-reference-video-prompt. If any image also defines or preserves a character, identity, person, object, costume, scene, style, voice, action, camera, composition, or other reusable trait, use full-reference even if the user also calls it a first or last frame.
Official Format Authority
Before drafting, read ../h3-prompt-writing/SKILL.md and ../h3-prompt-writing/references/base-en.txt. Treat those official MiniMax files as the canonical prompt-format specification. If this skill or its local references conflict with them, follow the official files.
Read references/keyframe-rules.md before drafting.
Confirmed Multishot Handoff
When the director supplies a confirmed multishot_plan, treat its shot count, timing, content, framing, performance, camera, transitions, sound, and continuity decisions as already answered. Do not ask those questions again. Map every confirmed shot into the official keyframe prompt while preserving exact boundary-frame alignment. Reopen a decision only when the plan is physically impossible, contradicts a boundary image, or exceeds the effective duration.
Mandatory Format
Always return the exact mode-specific picture-alignment instruction followed by the official three fields. Never return a free-form natural-language paragraph, keyword list, shortened prompt, or alternate schema as the final English prompt.
Interactive Direction Check
Before drafting, use the host's structured-choice tool whenever the eligible pure-keyframe brief is sparse, the intended transformation is underspecified, two or more of duration, motion path, visual treatment, camera strategy, dialogue/sound, or ending behavior are missing, or the user delegates creative direction to the AI.
What ships with it
2 files 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-keyframe-video-prompt is a skill published in the GitHub repository unknowlei/minimax-h3-opencode-skills (112 stars, last pushed 1mo ago), licensed MIT. It adds 108 tokens to every session and 1,910 once invoked, about $0.0005 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.
