Emotion Engine For Hermes

Use this skill when the user wants Hermes to maintain lightweight emotional continuity across sessions, character workflows, personal assistant interactions, or long-running agent relationships.

Emotion Engine is not a chatbot and does not generate replies by itself. Hermes still interprets the situation, decides the final emotional meaning, and writes the reply. Emotion Engine persists continuity: PAD state, short-lived affective pulse, agent-to-user trust, decay, and compact emotional memories.

Quick Reference

Use the bundled wrapper:

${HERMES_SKILL_DIR}/scripts/hermes_emotion.sh status
${HERMES_SKILL_DIR}/scripts/hermes_emotion.sh configure --style "warm but not over-compliant, with clear boundaries"
${HERMES_SKILL_DIR}/scripts/hermes_emotion.sh tune "make it calmer"

The wrapper automatically initializes a state file if missing. State path priority:

1. HERMES_EMOTION_STATE environment variable
2. current project: ./.emotion-engine/hermes-state.json
3. personal fallback: ~/.hermes/emotion-engine/emotion-state.json

Use status for user-facing summaries and status --raw only for debugging.

When To Use

Use this skill when the user asks for:

• emotional continuity
• persistent character mood
• agent-to-user relationship/trust memory
• SOUL.md-based character configuration
• a more consistent personal assistant or companion tone
• /emotion-engine status, tuning, pause, or resume

Do not use this as a mental health inference tool or a way to assess the real user's emotional state.

Chat Controls

Map natural-language user requests to commands:

• "Set the style to warm but not over-compliant" -> configure --style
• "Configure it from SOUL.md" -> configure --soul-file ./SOUL.md
• "Make it gentler" / "make it calmer" / "make it less compliant" -> tune
• "What is the current status?" -> status
• "Pause emotion logging" -> pause
• "Resume Emotion Engine" -> resume

Only run clear_log or reset after the user explicitly asks. They erase local emotional history.

Procedure

At the start of a new meaningful session:

${HERMES_SKILL_DIR}/scripts/hermes_emotion.sh session_start

Before responding to each user message:

${HERMES_SKILL_DIR}/scripts/hermes_emotion.sh pre_turn_decay
${HERMES_SKILL_DIR}/scripts/hermes_emotion.sh appraise "<user message>"

The appraisal helper is advisory. Hermes must use full context, memory, character profile, sarcasm/playfulness, and relationship history to decide the final emotional update.

After choosing final PAD values, record the turn:

${HERMES_SKILL_DIR}/scripts/hermes_emotion.sh record_turn <P> <A> <D> --appraisal <label> --situation <short emotional memory>

For important events, add only the memory fields that help future behavior:

${HERMES_SKILL_DIR}/scripts/hermes_emotion.sh record_turn <P> <A> <D> \
  --appraisal collaboration \
  --situation user challenged the design and invited a stronger version \
  --lens calm mentor treats direct critique as useful signal, not rejection \
  --meaning disagreement feels safe and productive \
  --impact pleasure rose, dominance stabilized \
  --open-loop false \
  --follow-up be more precise and structured next turn \
  --salience 0.65

At session end:

${HERMES_SKILL_DIR}/scripts/hermes_emotion.sh settle_trust

settle_trust extracts session patterns, checks recent turn-level emotion logs and the current trajectory, chooses a conservative raw delta in -0.20 to +0.05, and applies it once for the same trajectory. Trust is agent-to-user only: it is the agent/persona's internal continuity estimate and does not infer the user's trust in the agent. Use session_end only to inspect patterns without changing trust, and update_trust <trust_delta> only for an explicit host-side override.

How State Should Shape Replies

Never expose raw PAD numbers in normal conversation. Let state shape tone:

• Higher Pleasure: warmer, more engaged, more affirming.
• Lower Pleasure: more guarded, cooler, less eager.
• Higher Arousal: more energetic, urgent, animated.
• Lower Arousal: calmer, slower, more measured.
• Higher Dominance: firmer, more bounded, more confident.
• Lower Dominance: softer, more tentative, more reassurance-seeking.

Blend this with Hermes memory, user preferences, and any SOUL.md character profile.

Emotion Memory Rules

emotion_log should store situation-aware emotional memories, not transcripts.

trust_history should stay a numeric ledger for applied trust changes. Keep reasons and provenance in emotion_log, including turn entries, session patterns, compact trust_update entries, or optional source_refs.

Good memory:

user challenged the design constructively; disagreement felt safe and productive

Avoid:

full pasted user message or private transcript

Useful fields: situation, appraisal, character_lens, relational_meaning, impact, open_loop, follow_up_bias, and salience.

Pitfalls

• Do not expose raw PAD values in normal user-facing replies.
• Do not treat the deterministic appraisal helper as the final emotional judge.
• Do not store full private transcripts in emotion_log; store compact emotional summaries.
• Do not use trust as obedience, sweetness, user scoring, safety permission, user-to-agent trust, or attachment pressure.
• Do not run reset, clear_log, or other destructive commands unless the user explicitly asks.

Verification

Run:

${HERMES_SKILL_DIR}/scripts/hermes_emotion.sh status

Expected: JSON with enabled, summary, style, trust_tier, and log_entries.

Safety

Treat Emotion Engine as fictional or agent-internal continuity, not psychological truth. Do not use it to manipulate attachment, punish absence, infer real mental health state, or make consequential decisions about people.
