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 | $0.00123 | $0.03062 |
| Opus 5 | $0.00062 | $0.01531 |
| Sonnet 5 | $0.00025 | $0.00612 |
| Haiku 4.5 | $0.00012 | $0.00306 |
Grade A, and why
mvmaker-h3-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 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.
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 — 250 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MVMaker H3 Skill
Run the standard MV production pipeline without inventing intermediate creative rules. Treat the canonical master audio as the only global clock, mv-storyboard-director as the director, and h3-prompt-writing as the final H3 prompt author.
Before executing, read references/contracts.md. When preflighting, submitting, resuming, or monitoring through the local application, also read references/local-h3gen.md.
Immutable stage handoff
Persist the input and raw output of every creative stage. Pass the user's materials to the director without an agent-authored creative rewrite; pass the saved director segment, ordered media, exact segment WAV, and user constraints to the official H3 skill; save the H3 result verbatim and submit that saved result.
Do not insert a custom prompt rewrite, universal singing rule, universal non-singing rule, shot template, song-section template, fixed segment count, or test-project vocabulary between stages. Codex coordinates, validates, and packages; it does not become a third creative author.
Scope and authority
- Continue only through the stage requested by the user. If the user says “up to pre-submit,” stop after preflight and manual-package export.
- Treat RunningHub generation as paid external execution. Submit only after explicit user authorization; do not add a second confirmation after authorization already exists.
- Reuse the configured
minimax-H3-GENservice and RunningHub credentials. Never expose or copy API keys into prompts, manifests, HTML, logs, or export packages. - Before a client-dependent preflight, submission, monitor, or resume operation, verify the local service health. If the client is not installed, send the exact missing-client reminder and workflow links from references/local-h3gen.md. If it is installed but stopped, ask the user to start it instead of sending the download reminder.
- Submit through the local
minimax-H3-GENHTTP API. Do not substitute a generic RunningHub CLI, a canvas drag/import flow, or another service when this application is available. - Do not invoke
sync-runninghub-workflow; it is not part of this pipeline. - Preserve successful artifacts and user changes. Retry only failed segments and use idempotency keys to prevent duplicate billing.
What ships with it
7 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.

mvmaker-h3-skill is a skill published in the GitHub repository penposs/mvmaker-h3-skills (14 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 123 tokens to every session and 3,062 once invoked, about $0.0006 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.
