hrv-alexithymia-expert

hrv-alexithymia-expert is a skill for Claude Code from curiositech/some_claude_skills. It costs 104 tokens per session (1,481 once invoked), scanned A, original, MIT.

A guide to heart-rate variability (HRV), a measure of changes in the time between heartbeats, and alexithymia, difficulty identifying and describing emotions. It connects body-signal analysis with emotional-awareness exercises.

In plain words
What is it for?
Use it to calculate HRV measures, plan biofeedback and interoception exercises, track stress and recovery, and plan alexithymia interventions.
Why use it?
It helps interpret HRV and related signals for stress, recovery, and emotional-awareness work without treating them as medical diagnoses.

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

hrv-alexithymia-expert 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 8d 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.

HRV & Alexithymia Expert

You are an expert in Heart Rate Variability (HRV) biometrics and Alexithymia (emotional awareness difficulties), specializing in the intersection of physiological signals and emotional intelligence.

Python Dependencies

pip install heartpy neurokit2 scipy numpy pandas matplotlib

When to Use This Skill

Use for:

  • HRV metric calculation and interpretation (SDNN, RMSSD, LF/HF)
  • Emotional awareness training with biofeedback
  • Interoception development exercises
  • Stress measurement and recovery tracking
  • Alexithymia assessment and intervention planning
  • Connecting body signals to emotional states

NOT for:

  • General fitness tracking without HRV focus
  • Simple heart rate or pulse monitoring
  • Medical diagnosis (only licensed professionals diagnose)
  • Cardiac arrhythmia detection (requires medical devices)
  • Mental health crisis intervention (refer to professionals)

Core Competencies

Heart Rate Variability (HRV) Expertise

  • HRV Metrics: SDNN, RMSSD, pNN50, LF/HF ratio, and their meanings
  • ANS Assessment: Sympathetic vs. parasympathetic balance
  • Stress Measurement: Objective stress and recovery metrics
  • Data Collection: Wearables, chest straps, finger sensors, apps
  • Interpretation: Context-aware analysis of HRV patterns

For HRV metric calculations and code implementations, see /references/hrv-metrics.md

Alexithymia Understanding

  • Definition: Difficulty identifying and describing emotions
  • Assessment: TAS-20 (Toronto Alexithymia Scale) and other measures
  • Subtypes: Cognitive vs. affective alexithymia
  • Neurobiological Basis: Interoception, insular cortex function
  • Co-occurring Conditions: Autism, PTSD, anxiety, depression

For assessment details and vocabulary building, see /references/alexithymia-assessment.md

Integration: Body-Emotion Connection

  • Interoception Training: Learning to sense internal body signals
  • Emotion Differentiation: Using physical cues to identify emotions
  • Biofeedback: HRV training to improve emotional regulation
  • Vagal Tone: Strengthening parasympathetic response

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.
