pause-detector

pause-detector is a skill for Claude Code, Codex from xuansenpa1/skillrevise. It costs 48 tokens per session (626 once invoked), scanned A, original, MIT.

An audio-analysis tool that finds pauses and quiet stretches by comparing each part with the sound around it.

In plain words
What is it for?
Use it to locate pauses in lectures, board-writing sessions, and sections of spoken content for editing.
Why use it?
It helps detect natural breaks even when the speaker’s overall volume changes during the recording.

Token cost

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.

Security

Grade A, and why

pause-detector 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/detect_pauses.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

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

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

{
  "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

# 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

Parameter Lower Value Higher Value
threshold_ratio More aggressive More conservative
min_duration Shorter pauses Longer pauses only
window_size Local context Broader context

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.

Changes

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.

pause-detector is a skill published in the GitHub repository xuansenpa1/skillrevise (56 stars, last pushed 7d ago), licensed MIT. It adds 48 tokens to every session and 626 once invoked, about $0.0002 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 2026-09-03.
