What it does

Pause Detector is an agent skill from benchflow-ai/skillsbench. Detect pauses and silence in audio using local dynamic thresholds. Use when you need to find natural pauses in lectures, board-writing silences, or breaks between sections. Uses local context comparison to avoid false positives from volume variation.

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/detect_pauses.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 find natural pauses in lectures
  • Board-writing silences
  • Breaks between sections

Example prompts

  • “/pause-detector”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Load pre-computed energy data
  2. Calculate local average using sliding window
  3. Mark seconds where energy < local_avg × threshold_ratio
  4. Group consecutive low-energy seconds into segments
  5. Filter segments by minimum duration

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

Pause Detector loads about 642 tokens when it runs. Until then it costs about 66 tokens; SKILL.md has 181 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~66
When it runs · the whole SKILL.md, loaded when a task matches
~642

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.

description
Detect pauses and silence in audio using local dynamic thresholds. Use when you need to find natural pauses in lectures, board-writing silences, or breaks between sections. Uses local context comparison to avoid false positives from volume variation.

Pause Detector

Detects pauses and low-energy segments using local dynamic thresholds on pre-computed energy data. Unlike global threshold methods, this compares energy to surrounding context, avoiding false positives when speaker volume varies.

Use Cases

  • Detecting natural pauses in lectures
  • Finding board-writing silences
  • Identifying breaks between sections

Usage

bash
python3 /root/.claude/skills/pause-detector/scripts/detect_pauses.py \
    --energies /path/to/energies.json \
    --output /path/to/pauses.json
Parameters
  • --energies: Path to energy JSON file (from energy-calculator)
  • --output: Path to output JSON file
  • --start-time: Start analyzing from this second (default: 0)
  • --threshold-ratio: Ratio of local average for low energy (default: 0.5)
  • --min-duration: Minimum pause duration in seconds (default: 2)
  • --window-size: Local average window size (default: 30)
Output Format
json
{
  "method": "local_dynamic_threshold",
  "segments": [
    {"start": 610, "end": 613, "duration": 3},
    {"start": 720, "end": 724, "duration": 4}
  ],
  "total_segments": 11,
  "total_duration_seconds": 28,
  "parameters": {
    "threshold_ratio": 0.5,
    "window_size": 30,
    "min_duration": 2
  }
}

How It Works

  1. Load pre-computed energy data
  2. Calculate local average using sliding window
  3. Mark seconds where energy < local_avg × threshold_ratio
  4. Group consecutive low-energy seconds into segments
  5. Filter segments by minimum duration

Dependencies

  • Python 3.11+
  • numpy
  • scipy

Example

bash
# Detect pauses after opening (start at 221s)
python3 /root/.claude/skills/pause-detector/scripts/detect_pauses.py \
    --energies energies.json \
    --start-time 221 \
    --output pauses.json

# Result: Found 11 pauses totaling 28 seconds

Parameters Tuning

ParameterLower ValueHigher Value
threshold_ratioMore aggressiveMore conservative
min_durationShorter pausesLonger pauses only
window_sizeLocal contextBroader context

Notes

  • Requires energy data from energy-calculator skill
  • Use --start-time to skip detected opening
  • Local threshold adapts to varying speaker volume
