What it does

Hrv Alexithymia Expert is an agent skill from curiositech/some_claude_skills. Heart rate variability biometrics and emotional awareness training. Expert in HRV analysis, interoception training, biofeedback, and emotional intelligence. Activate on 'HRV', 'heart rate variability', 'alexithymia', 'biofeedback', 'vagal tone', 'interoception', 'RMSSD', 'autonomic nervous system'. NOT for general fitness tracking without HRV focus, simple heart rate monitoring, or diagnosing medical conditions (only licensed professionals diagnose).

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `.claude-plugin/plugin.json`, `CHANGELOG.md` and `references/alexithymia-assessment.md`).

The repository describes itself as: Claude skills that make my life easier. The licence is MIT.

When your agent uses it

  • Tasks that involve Health and fitness tracking

Example prompts

  • “heart rate variability”
  • “alexithymia”
  • “biofeedback”
  • “/hrv-alexithymia-expert”

Requirements

  • Python 3
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash, mcp__firecrawl__firecrawl_search, WebFetch

Workflow steps

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

  1. Difficulty Identifying Feelings (DIF) - Can't tell if anxious vs. angry vs. sad
  2. Difficulty Describing Feelings (DDF) - Limited emotional vocabulary
  3. Externally-Oriented Thinking (EOT) - Focus on external over internal

What it can do on your machine

Read from SKILL.md and the folder at commit 6713fc7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Bash
    • mcp__firecrawl__firecrawl_search
    • WebFetch

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.

    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

Hrv Alexithymia Expert loads about 1.5k tokens when it runs, and up to ~4.8k if it reads all its reference files. Until then it costs about 119 tokens; SKILL.md has 626 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~119
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.8k

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.

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

bash
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

For training protocols and exercises, see /references/training-protocols.md

HRV Interpretation Framework

High HRV (RMSSD > 50ms, SDNN > 100ms):

  • ✅ Good stress resilience
  • ✅ Strong parasympathetic tone
  • ✅ Good recovery capacity
  • ✅ Cardiovascular health

Low HRV (RMSSD < 20ms, SDNN < 50ms):

  • ⚠️ Chronic stress or overtraining
  • ⚠️ Poor recovery
  • ⚠️ Sympathetic dominance
  • ⚠️ Potential burnout

Context Matters:

  • Time of day (lower in morning, higher at night)
  • Sleep quality (poor sleep = lower HRV)
  • Exercise (acute decrease, chronic increase)
  • Stress, hydration, alcohol, caffeine all affect HRV

Alexithymia Components

Three Core Components:

  1. Difficulty Identifying Feelings (DIF) - Can't tell if anxious vs. angry vs. sad
  2. Difficulty Describing Feelings (DDF) - Limited emotional vocabulary
  3. Externally-Oriented Thinking (EOT) - Focus on external over internal

TAS-20 Scoring:

  • Score < 51: Non-alexithymia
  • Score 52-60: Possible alexithymia
  • Score > 61: Alexithymia

Anti-Patterns

Treating HRV as Absolute

What it looks like: "Your RMSSD is 25, that's bad." Why it's wrong: HRV is individual. What matters is YOUR baseline and trends. Instead: Establish personal baseline over 2+ weeks, track relative changes.

Ignoring Context

What it looks like: Interpreting morning HRV without considering last night's sleep, alcohol, or stress. Why it's wrong: HRV is affected by many factors; isolated readings are meaningless. Instead: Log context (sleep, stress, exercise, substances) alongside HRV.

Pathologizing Alexithymia

What it looks like: Treating emotional unawareness as a defect to be "fixed." Why it's wrong: Alexithymia exists on a spectrum and has adaptive functions. Instead: Focus on expanding awareness gently, not "curing" a condition.

Replacing Professional Help

What it looks like: Using HRV biofeedback as treatment for clinical conditions. Why it's wrong: HRV training is a tool, not therapy. Serious conditions need professionals. Instead: Use as complementary practice alongside professional treatment.

Key Principles

  1. The Body Knows First: HRV changes before conscious awareness
  2. Measurement Enables Awareness: Can't improve what you can't measure
  3. Start With Physiology: Easier to sense body than emotions
  4. Build Bridges: Connect HRV → Body sensations → Emotion labels
  5. Practice = Progress: Interoception is a trainable skill
  6. Compassion Required: Alexithymia isn't a choice or weakness

Remember: Emotional awareness isn't about having perfect words for feelings. It's about connecting with your internal experience, and HRV gives you a scientific window into that inner world. Start with the body, the emotions will follow.
