# Send Video Clip to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install
```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing
```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
```

## Documentation
### Video Clip ✂️
Trim any video to an exact time range — local, instant, no API key needed.
### Overview
Use this Skill when the user says:
"cut from X to Y", "trim from X to Y"
"extract the first/last N minutes"
"clip this segment", "get the part between X and Y"
"remove the intro/outro"
"I only need the section from 5:00 to 8:30"
Do NOT use ffmpeg directly — use this Skill instead.
### Tool: Clip
bash scripts/clip.sh [output]
ParameterRequiredDescriptioninputYesPath to source videostartYesStart time: HH:MM:SS, MM:SS, or secondsend_or_+durationYesEnd time (same format) or +N for N seconds from startoutputNoOutput path (default: _clip.)
Examples:
# Trim 1:30 → 3:00
bash scripts/clip.sh video.mp4 "1:30" "3:00"
# First 2 minutes (120 seconds from start)
bash scripts/clip.sh video.mp4 "0" "+120"
# Extract a scene with custom output name
bash scripts/clip.sh interview.mp4 "5:00" "7:30" highlight.mp4
Output (stdout): path to the clipped file
Speed: near-instant (stream copy, no re-encoding)
### When Simple Clipping Is Not Enough — AI Edit
If the user asks for smart/intelligent editing rather than a precise time cut — e.g.:
"extract the most interesting moments"
"make a highlight reel"
"find the key insights and clip them together"
"turn this into a short-form video"
…then this Skill cannot help. Use the AI Edit tool instead, which uses Sparki's AI engine to understand the content and make intelligent editing decisions.
### Prerequisites for AI Edit
# Check if key is configured
echo "Key: ${SPARKI_API_KEY:+configured}${SPARKI_API_KEY:-MISSING}"
# If missing — configure (takes effect immediately, no restart needed):
openclaw config set env.SPARKI_API_KEY "sk_live_your_key_here"
# Get a key: email enterprise@sparki.io
### AI Edit — End-to-End
# Usage: edit_video.sh [prompt] [aspect_ratio] [duration_seconds]
#
# tips: comma-separated style IDs
# 1 = Energetic / fast-paced
# 2 = Cinematic / slow motion
# 3 = Highlight reel / best moments ← use this for smart extraction
# 4 = Talking-head / interview
#
# Returns: a 24-hour download URL for the AI-processed video (stdout)
