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 A, and why

video-prep AGENTS.md 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 17d 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.

What it actually says

video-prep

This repo provides the video-prep skill and the video-prep-edit CLI for prepping raw video clips before the real edit: cut silent gaps, transcribe subtitles (any language, auto-detected), normalize speed, and stitch clips in natural numeric order — outputting clean per-clip .mp4 + .srt plus an optional merged, subtitle-burned preview. Pre-processing, not the creative edit.

When the user asks to "clean up / prep / edit my clips" (usually in ./raw/), process the whole folder in one run — never merge clips pairwise yourself:

video-prep-edit ./raw            # language auto-detected; or --language en / es / zh
video-prep-edit ./raw -j 3       # parallelize many clips on a multi-core CPU

Full, authoritative guidance lives in the skill — read it before running:

Requires ffmpeg (and ffmpeg-full to burn subtitles) on the machine.

Changes

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.
