What it does
Energy Calculator is an agent skill from benchflow-ai/skillsbench. Calculate per-second RMS energy from audio files. Use when you need to analyze audio volume patterns, prepare data for silence/pause detection, or create an energy profile for audio analysis tasks.
Its SKILL.md is about 440 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/calc_energy.py`).
The repository describes itself as: SkillsBench evaluates how well skills work and how effective agents are at using them. The licence is Apache-2.0.
When your agent uses it
- You need to analyze audio volume patterns
- Prepare data for silence/pause detection
- Create an energy profile for audio analysis tasks
Example prompts
- “/energy-calculator”
Requirements
- Python 3
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Load audio file
- Split into 1-second windows
- Calculate RMS energy for each window: sqrt(mean(samples^2))
- Output array of energy values
What it can do on your machine
Read from SKILL.md and the folder at commit 9a1f4dd. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Energy Calculator loads about 437 tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 126 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

- energy-calculator
- description
- Calculate per-second RMS energy from audio files. Use when you need to analyze audio volume patterns, prepare data for silence/pause detection, or create an energy profile for audio analysis tasks.
Energy Calculator
Calculates per-second RMS (Root Mean Square) energy from audio files. Produces an energy profile that can be used for opening detection, pause detection, or other audio analysis tasks.
Use Cases
- Calculating audio energy for silence detection
- Preparing data for opening/pause detection
- Analyzing audio volume patterns
Usage
python3 /root/.claude/skills/energy-calculator/scripts/calc_energy.py \
--audio /path/to/audio.wav \
--output /path/to/energies.jsonParameters
--audio: Path to input WAV file--output: Path to output JSON file--window-seconds: Window size for energy calculation (default: 1 second)
Output Format
{
"sample_rate": 16000,
"window_seconds": 1,
"total_seconds": 600,
"energies": [123.5, 456.7, 234.2, ...],
"stats": {
"min": 45.2,
"max": 892.3,
"mean": 234.5,
"std": 156.7
}
}How It Works
- Load audio file
- Split into 1-second windows
- Calculate RMS energy for each window:
sqrt(mean(samples^2)) - Output array of energy values
Dependencies
- Python 3.11+
- numpy
Example
# Calculate energy from extracted audio
python3 /root/.claude/skills/energy-calculator/scripts/calc_energy.py \
--audio audio.wav \
--output energies.jsonNotes
- RMS energy correlates with perceived loudness
- Higher values = louder audio, lower values = quieter/silence
- Output can be used by opening-detector and pause-detector skills
