Continuous Learning v2 - Instinct-Based Architecture

An advanced learning system that turns your Gemini CLI sessions into reusable knowledge through atomic "instincts" - small learned behaviors with confidence scoring.

What's New in v2

Feature	v1	v2
Observation	Stop hook (session end)	PreToolUse/PostToolUse (100% reliable)
Analysis	Main context	Background agent (Haiku)
Granularity	Full skills	Atomic "instincts"
Confidence	None	0.3-0.9 weighted
Evolution	Direct to skill	Instincts → cluster → skill/command/agent
Sharing	None	Export/import instincts

The Instinct Model

An instinct is a small learned behavior:

---
id: prefer-functional-style
trigger: "when writing new functions"
confidence: 0.7
domain: "code-style"
source: "session-observation"
---

# Prefer Functional Style

## Action
Use functional patterns over classes when appropriate.

## Evidence
- Observed 5 instances of functional pattern preference
- User corrected class-based approach to functional on 2025-01-15

Properties:

• Atomic — one trigger, one action
• Confidence-weighted — 0.3 = tentative, 0.9 = near certain
• Domain-tagged — code-style, testing, git, debugging, workflow, etc.
• Evidence-backed — tracks what observations created it

Quick Start

1. Enable Observation Hooks

Add to your ~/.gemini/settings.json.

If installed as a plugin (recommended):

{
  "hooks": {
    "PreToolUse": [{
      "matcher": "*",
      "hooks": [{
        "type": "command",
        "command": "${GEMINI_EXTENSION_ROOT}/skills/continuous-learning-v2/hooks/observe.sh pre"
      }]
    }],
    "PostToolUse": [{
      "matcher": "*",
      "hooks": [{
        "type": "command",
        "command": "${GEMINI_EXTENSION_ROOT}/skills/continuous-learning-v2/hooks/observe.sh post"
      }]
    }]
  }
}

If installed manually to ~/.gemini/skills:

{
  "hooks": {
    "PreToolUse": [{
      "matcher": "*",
      "hooks": [{
        "type": "command",
        "command": "~/.gemini/skills/continuous-learning-v2/hooks/observe.sh pre"
      }]
    }],
    "PostToolUse": [{
      "matcher": "*",
      "hooks": [{
        "type": "command",
        "command": "~/.gemini/skills/continuous-learning-v2/hooks/observe.sh post"
      }]
    }]
  }
}

2. Initialize Directory Structure

The Python CLI will create these automatically, but you can also create them manually:

mkdir -p ~/.gemini/homunculus/{instincts/{personal,inherited},evolved/{agents,skills,commands}}
touch ~/.gemini/homunculus/observations.jsonl

3. Use the Instinct Commands

/egc-instinct-status     # Show learned instincts with confidence scores
/egc-evolve              # Cluster related instincts into skills/commands
/egc-instinct-export     # Export instincts for sharing
/egc-instinct-import     # Import instincts from others

Commands

Command	Description
/egc-instinct-status	Show all learned instincts with confidence
/egc-evolve	Cluster related instincts into skills/commands
/egc-instinct-export	Export instincts for sharing
/egc-instinct-import <file>	Import instincts from others

Configuration

Edit config.json:

{
  "version": "2.0",
  "observation": {
    "enabled": true,
    "store_path": "~/.gemini/homunculus/observations.jsonl",
    "max_file_size_mb": 10,
    "archive_after_days": 7
  },
  "instincts": {
    "personal_path": "~/.gemini/homunculus/instincts/personal/",
    "inherited_path": "~/.gemini/homunculus/instincts/inherited/",
    "min_confidence": 0.3,
    "auto_approve_threshold": 0.7,
    "confidence_decay_rate": 0.05
  },
  "observer": {
    "enabled": true,
    "model": "haiku",
    "run_interval_minutes": 5,
    "patterns_to_detect": [
      "user_corrections",
      "error_resolutions",
      "repeated_workflows",
      "tool_preferences"
    ]
  },
  "evolution": {
    "cluster_threshold": 3,
    "evolved_path": "~/.gemini/homunculus/evolved/"
  }
}

Integration with Skill Creator

When you use the Skill Creator GitHub App, it now generates both:

• Traditional SKILL.md files (for backward compatibility)
• Instinct collections (for v2 learning system)

Instincts from repo analysis have source: "repo-analysis" and include the source repository URL.

Confidence Scoring

Confidence evolves over time:

Score	Meaning	Behavior
0.3	Tentative	Suggested but not enforced
0.5	Moderate	Applied when relevant
0.7	Strong	Auto-approved for application
0.9	Near-certain	Core behavior

Confidence increases when:

• Pattern is repeatedly observed
• User doesn't correct the suggested behavior
• Similar instincts from other sources agree

Confidence decreases when:

• User explicitly corrects the behavior
• Pattern isn't observed for extended periods
• Contradicting evidence appears

Why Hooks vs Skills for Observation?

"v1 relied on skills to observe. Skills are probabilistic—they fire ~50-80% of the time based on Gemini's judgment."

Hooks fire 100% of the time, deterministically. This means:

• Every tool call is observed
• No patterns are missed
• Learning is comprehensive

Backward Compatibility

v2 is fully compatible with v1:

• Existing ~/.gemini/skills/learned/ skills still work
• Stop hook still runs (but now also feeds into v2)
• Gradual migration path: run both in parallel

Privacy

• Observations stay local on your machine
• Only instincts (patterns) can be exported
• No actual code or conversation content is shared
• You control what gets exported
