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 | $0.00056 | $0.00779 |
| Opus 5 | $0.00028 | $0.00390 |
| Sonnet 5 | $0.00011 | $0.00156 |
| Haiku 4.5 | $0.00006 | $0.00078 |
Grade A, and why
audio-fade 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 9d 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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Audio Fade
Apply fade-in at the start and fade-out at the end without changing clip length.
Rules
When this skill applies, read and follow skill-dependency-manager �?run scripts as documented, install missing tools into .dependency/.
Quick Start
Default: 1 s fade-in and fade-out, output to <audio-dir>/audio-fade/<audio-name>:
.dependency/python/python .ai/audio-fade/fade.py --audio path/to/audio.wav
Fade-in only (keep full end level):
.dependency/python/python .ai/audio-fade/fade.py --audio path/to/audio.wav --no-fade-out
Custom durations (seconds):
.dependency/python/python .ai/audio-fade/fade.py --audio audio/sfx.wav -fi 0.05 -fo 0.15
Duration Guidelines
| Asset | Fade-in | Fade-out |
|---|---|---|
| UI clicks / ticks | 0.01�?.05 s | 0.02�?.08 s |
| Impacts / weapons | 0.02�?.08 s | 0.05�?.15 s |
| Voice lines | 0.05�?.15 s | 0.1�?.25 s |
| Ambience beds | 0.3�?.0 s | 0.5�?.0 s |
| BGM one-shots | 0.2�?.5 s | 0.3�?.0 s |
Fade-in + fade-out must stay shorter than file duration. Very short clips need smaller values.
Common Flags
--audio · -fi / --fade-in · -fo / --fade-out · --no-fade-in · --no-fade-out · -o / --output
.dependency/python/python .ai/audio-fade/fade.py --audio audio/sfx.wav -fi 0.03 -fo 0.08
Originals are never modified. Input must be a single audio file (--audio), not a directory. Supported: .wav, .mp3, .ogg, .flac, .aac, .m4a, .wma.
Fades use FFmpeg afade with the linear tri curve. The script probes clip duration and places fade-out at duration - fade_out.
Scope
- Fade shapes volume at clip boundaries without changing its duration.
- Trim removes silence or crops boundaries; use the
audio-trimskill. - Crossfade overlaps two clips and is not performed by this skill.
Agent Notes
- Use the bundled script, not hand-written
afadefilters. - Looping BGM �?avoid fade-out on loop assets; use
--no-fade-outor fade-in only for one-shot intros. - Clicks with instant attack �?
--no-fade-inor lower-fi(e.g.0.01). - Tail cut off abruptly after fade �?increase
-fo; tail too soft �?decrease-fo.
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.
- 9d ago First seen · 74 lines · 56 tokens per session scan A 0853cfb47a2f
audio-fade is a skill published in the GitHub repository godot-fun/godot-framework (116 stars, last pushed 9d ago), licensed MIT. It adds 56 tokens to every session and 779 once invoked, about $0.0003 per session on Opus 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.
