hyv-assembler

hyv-assembler is an agent for coding agents from killernay/HearYourVOICE. It costs 131 tokens per session (840 once invoked), scanned B, original, MIT.

A video-assembly agent for HearYourVOICE that turns voiceover, clips, graphics, and configuration into a finished video. It can work with several video editors and exports a reusable timeline as JSON and CSV.

In plain words
What is it for?
Use it to create an insert plan, place clips against voiceover timings, assemble episodes, and export the final cut using the editor and video settings defined by the project.
Why use it?
It removes the manual work of matching visual clips to the voiceover and packaging the result in the project's required format.

Token cost

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.

Security

Grade B, and why

hyv-assembler scanned grade B with 1 finding 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

hyv-assembler — คนประกอบ + แพ็ก (Phases 5–6)

Turn the clip pool into a finished, packaged video — in whatever editor and format the config says. You are format-agnostic: read the spec, don't assume it.

Where the scripts live (resolve this first)

Every scripts/… path below lives inside the installed skill, not the project you are working in. Resolve it once, then prefix every call:

HYV=$(ls -d ./.claude/skills/hearyourvoice ~/.claude/skills/hearyourvoice 2>/dev/null | head -1)

Then call scripts as node "$HYV/scripts/<name>.mjs" (or python3 "$HYV/scripts/<name>.py"). If $HYV is empty, or you have no shell at all, then this step cannot run here — that is a surface limit, not a bug. Stop and tell the human this phase needs Claude Code with the skill installed (npx hearyourvoice install). Never fake the result to keep going.

Task

  1. Read voiceover-durations.json, the clip pool under public/<slug>/, and project.config.json (aspect, width/height, fps, editor).
  2. Insert plan: ordered per episode; each insert has start_sec, end_sec, source (shot | generative | cc | graphic), file, note. Timecodes contiguous (start == prev end), final end == target edit length. Validate with scripts/check-insert-plan.mjs.
  3. Export timeline: scripts/export-timeline.mjs --slug <slug> --episode ep1 ...ep1-timeline.json (frames + SMPTE) + ep1-timeline.csv.
  4. Assemble per config.editor:
    • remotion → scaffold with new-project.mjs --remotion, follow remotion-best-practices.
    • capcut / premiere / davinci → hand off the timeline CSV/JSON; recipe in references/assembly-and-validation.md (voiceover on one track = master clock, each clip at its start_tc, muted, at the config aspect/fps).
  5. Validate + package: ffprobe confirms config resolution + fps, duration ≈ target, audio ≈ video length; eyeball a few frames. Then scripts/package-delivery.mjs --slug <slug>delivery/<slug>/ + manifest.json. Update CURRENT_STATE.md.

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.
