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.

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 | $0.00198 | $0.09333 |
| Opus 5 | $0.00099 | $0.04666 |
| Sonnet 5 | $0.00040 | $0.01867 |
| Haiku 4.5 | $0.00020 | $0.00933 |
Grade A, and why
video-use-best-practices scanned grade A 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 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
Symptom: `captions-only.sh` logs `WARN: gap re-transcribe returned HTTP <code>, skipping` and that window stays uncaptioned. Cause: Scribe v2 occasionally rate-limits, times out, or rejects very short or mid-word windows How it starts

video-use Best Practices (Hebrew)
Problem
video-use ships with a strong English-first default: the bundled SUB_FORCE_STYLE uses Helvetica (no Hebrew glyphs, renders as boxes), 2-word UPPERCASE chunks (Hebrew has no uppercase), and the filler-removal step assumes an English filler lexicon while Scribe itself does not tag fillers per-word in any language. Hebrew creators using video-use hit the same three walls every time: missing-glyph boxes burned into the final video, captions that look wrong because UPPERCASE doesn't exist in Hebrew, and a "filler removal" step that leaves "אֶה", "כאילו", "יעני", and friends in. On macOS there's also a fourth wall: libass + SRT BiDi reordering is unreliable even with a fully-built libass, so Hebrew sentences render as characters drawn left-to-right in source byte order rather than in proper RTL visual order. This skill is the Hebrew-specific override layer on top of video-use's 12 Hard Rules. None of the upstream rules change, only the style values, font fallback chain, filler lexicon, caption-burn recipe, and self-eval frame checks.
Pricing you should understand before you start
video-use is free; underlying services are paid. Mode determines cost.
| Mode | What | Best for | Cost / 1hr video |
|---|---|---|---|
A. Captions-only (scripts/captions-only.sh) |
Transcribe + burn Hebrew captions on original. No cuts. | Lectures, webinars, podcast videos. | ~$1-3 total |
| B. Full cut (default video-use flow) | Inventory, strategy, cut, render, self-eval. | Teaser from raw footage; multi-take selection. | ~$25-60 (1hr); $120-300 (3hr). Scales super-linearly. |
Scribe v2 is $0.22 per hour of audio on the API rate card. scribe_v1 was removed on 9 July 2026, so scribe_v2 is the only model the scripts may send. Claude tokens dominate Mode A's cost; local FFmpeg rendering is $0.
Two rate cards, do not mix them. $0.22/hr is pay-as-you-go API. On a subscription you spend credits: STT bills ~330 credits/minute, so an hour is 19,800 credits, two thirds of Starter's 30,000 ($6/mo). The free plan's 10,000/month covers ~30 minutes. Warn non-technical users upfront.

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.

video-use-best-practices is a skill published in the GitHub repository skills-il/developer-tools (10 stars, last pushed 6d ago), licensed MIT. It adds 198 tokens to every session and 9,333 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
