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 | $0.00106 | $0.01026 |
| Opus 5.5 | $0.00042 | $0.00410 |
| Sonnet 5.5 | $0.00021 | $0.00205 |
| Haiku 4.5 | $0.00011 | $0.00103 |
Grade A, and why
video-merge 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Video Merge
Concatenate every video in a folder (filename sort) into one high-quality MP4. Between each pair, pick a random FFmpeg xfade transition (0.5s). Audio uses matching acrossfade.
Duration is preserved: each cut freeze-pads the outgoing clip by 0.5s (last frame + silence) before the overlap, so output length equals the sum of source clip durations (not shortened by transitions).
Rules
When this skill applies, read and follow skill-dependency-manager �?run scripts as documented, install missing tools into .dependency/.
- Run
merge.pythrough.dependency/python/python.exe. Never use hostpython/ffmpeg. - Never overwrite sources. Outputs go under
video-merge/. - Use the bundled script �?do not hand-write equivalent FFmpeg commands.
- Folder input only �?pass
--folderwith a directory of clips (top-level files; no recurse).
Quick Start
.dependency/python/python .ai/video-merge/merge.py --folder path/to/clips
Example:
assets/shots/
01.mp4
02.mp4
03.mp4
�?assets/shots/video-merge/shots.mp4
Output Spec (fixed)
| Setting | Value |
|---|---|
| Resolution | 3840×2160 (scale + letterbox pad) |
| Frame rate | 60 fps |
| Video | H.265 Main10 (libx265, yuv420p10le) @ 40 Mbps |
| Audio | AAC 320 kbps, 48 kHz stereo |
| Transition | 0.5 s, random from the pool below (freeze-pad; duration preserved) |
| Container | .mp4 (hvc1 tag) |
Transition Pool (random per cut)
fade · dissolve · wipeleft · wiperight · wipeup · wipedown · slideleft · slideright · circlecrop · pixelize · distance · radial · smoothleft · smoothright · circleopen · circleclose · diagtl · diagtr · hblur · zoomin
Each cut independently samples one transition. Printed in the run log.

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-merge is a skill published in the GitHub repository godot-fun/godot-framework (116 stars, last pushed 1mo ago), licensed MIT. It adds 106 tokens to every session and 1,026 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
