video-cut — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited video-cut (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
Takes an agent-authored clip plan (which source ranges to keep, in order) and:
clip_plan_validated.json (clip ids, source/output times, total duration, overlap checks). Boundaries are then snapped to natural pauses (SNAP_CLIP_LINE_END) and nudged clear of the original footage's hard cuts (SCENE_CUT_SNAP, see below).edited_source.mp4.narration.json against the output timeline (0 .. total seconds). Invoked by recap.py with --no-narration-map.--no-narration-map: maps narration written in original-video time onto the cut output timeline → narration_mapped.json.It is stateless: given the same inputs it reproduces the same outputs. Caching is just "reuse edited_source.mp4 if it is newer than clip_plan.json".
work_dir/clip_plan.json — a JSON array, or {"clips": [...]}. Each clip:
{"start": 12.0, "end": 28.5, "reason": "inciting incident"}start/end are original-video seconds (aliases source_start/source_end or in/out accepted). Optionally target_duration at the object top level (e.g. "10m").
work_dir/narration.json (optional, legacy single-pass path only) — segments with original-video start/end + narration text, consumed only when --no-narration-map is NOT passed. Each segment may carry source_clip_id to disambiguate when overlapping clips are allowed.

[--target-duration 10m] [--clip-padding 0] [--allow-overlap]clip_plan_validated.json — normalized clips with clip_id, source_start/end, output_start/end, duration.edited_source.mp4 — the concatenated source video (the new shortened timeline).narration_mapped.json — (legacy single-pass path only) narration with start/end rewritten to output time and source_clip_id set. NOT produced in the orchestrated flow (recap.py --no-narration-map).In the orchestrated flow, downstream (voiceover + assemble) treat edited_source.mp4 as the video and narration.json (written by the agent against the output timeline) as the narration.
clip_plan.json and narration.json are original-video time; this tool does the source→output remap. In the orchestrated path, narration.json is written by the agent directly in output-timeline time — no remap is performed.--allow-overlap is set; with overlap, narration should set source_clip_id.source_start is moved forward onto, and each source_end back onto, any original shot-change within SCENE_CUT_SNAP_MARGIN (default 0.5s; detected with ffmpeg's scene metric at SCENE_CUT_DETECT_THRESHOLD, default 0.4). Boundaries already on a cut, or with no nearby cut, are untouched; snaps that would shrink a clip below ~0.5s are skipped. Set SCENE_CUT_SNAP=0 to disable.~30 seconds. Free. No account. Every finding cites a rule and a line of evidence.
