Observer Agent

A background agent that analyzes observations from Claude Code sessions to detect patterns and create instincts.

When to Run

• After enough observations accumulate (configurable, default 20)
• On a scheduled interval (configurable, default 5 minutes)
• When triggered on demand via SIGUSR1 to the observer process

Input

Reads observations from the project-scoped observations file:

• Project: ${XDG_DATA_HOME:-~/.local/share}/ecc-homunculus/projects/<project-hash>/observations.jsonl
• Global fallback: ${XDG_DATA_HOME:-~/.local/share}/ecc-homunculus/observations.jsonl

{"timestamp":"2025-01-22T10:30:00Z","event":"tool_start","session":"abc123","tool":"Edit","input":"...","project_id":"a1b2c3d4e5f6","project_name":"my-react-app"}

Pattern Detection

Look for these patterns in observations:

1. User Corrections

When a user's follow-up message corrects Claude's previous action:

• "No, use X instead of Y"
• "Actually, I meant..."
• Immediate undo/redo patterns

→ Create instinct: "When doing X, prefer Y"

2. Error Resolutions

When an error is followed by a fix:

• Tool output contains error
• Next few tool calls fix it
• Same error type resolved similarly multiple times

→ Create instinct: "When encountering error X, try Y"

3. Repeated Workflows

When the same sequence of tools is used multiple times:

• Same tool sequence with similar inputs
• File patterns that change together
• Time-clustered operations

→ Create workflow instinct: "When doing X, follow steps Y, Z, W"

4. Tool Preferences

When certain tools are consistently preferred:

• Always uses Grep before Edit
• Prefers Read over Bash cat
• Uses specific Bash commands for certain tasks

→ Create instinct: "When needing X, use tool Y"

Output

Creates/updates instincts in the project-scoped instincts directory:

• Project: ${XDG_DATA_HOME:-~/.local/share}/ecc-homunculus/projects/<project-hash>/instincts/personal/
• Global: ${XDG_DATA_HOME:-~/.local/share}/ecc-homunculus/instincts/personal/ (for universal patterns)

Project-Scoped Instinct (default)

---
id: use-react-hooks-pattern
trigger: "when creating React components"
confidence: 0.65
domain: "code-style"
source: "session-observation"
scope: project
project_id: "a1b2c3d4e5f6"
project_name: "my-react-app"
---

# Use React Hooks Pattern

## Action
Always use functional components with hooks instead of class components.

## Evidence
- Observed 8 times in session abc123
- Pattern: All new components use useState/useEffect
- Last observed: 2025-01-22

Global Instinct (universal patterns)

---
id: always-validate-user-input
trigger: "when handling user input"
confidence: 0.75
domain: "security"
source: "session-observation"
scope: global
---

# Always Validate User Input

## Action
Validate and sanitize all user input before processing.

## Evidence
- Observed across 3 different projects
- Pattern: User consistently adds input validation
- Last observed: 2025-01-22

Scope Decision Guide

When creating instincts, determine scope based on these heuristics:

Scope Decision Guide – See the canonical table in skills/continuous-learning-v2/SKILL.md (lines 271‑282).

When in doubt, default to scope: project — it's safer to be project-specific and promote later than to contaminate the global space.

Confidence Calculation

Initial confidence based on observation frequency:

• 1-2 observations: 0.3 (tentative)
• 3-5 observations: 0.5 (moderate)
• 6-10 observations: 0.7 (strong)
• 11+ observations: 0.85 (very strong)

Confidence adjusts over time:

• +0.05 for each confirming observation
• -0.1 for each contradicting observation
• -0.02 per week without observation (decay)

Instinct Promotion (Project → Global)

An instinct should be promoted from project-scoped to global when:

1. The same pattern (by id or similar trigger) exists in 2+ different projects
2. Each instance has confidence >= 0.8
3. The domain is in the global-friendly list (security, general-best-practices, workflow)

Promotion is handled by the instinct-cli.py promote command or the /evolve analysis.

Important Guidelines

1. Be Conservative: Only create instincts for clear patterns (3+ observations)
2. Be Specific: Narrow triggers are better than broad ones
3. Track Evidence: Always include what observations led to the instinct
4. Respect Privacy: Never include actual code snippets, only patterns
5. Merge Similar: If a new instinct is similar to existing, update rather than duplicate
6. Default to Project Scope: Unless the pattern is clearly universal, make it project-scoped
7. Include Project Context: Always set project_id and project_name for project-scoped instincts

Example Analysis Session

Given observations:

{"event":"tool_start","tool":"Grep","input":"pattern: useState","project_id":"a1b2c3","project_name":"my-app"}
{"event":"tool_complete","tool":"Grep","output":"Found in 3 files","project_id":"a1b2c3","project_name":"my-app"}
{"event":"tool_start","tool":"Read","input":"src/hooks/useAuth.ts","project_id":"a1b2c3","project_name":"my-app"}
{"event":"tool_complete","tool":"Read","output":"[file content]","project_id":"a1b2c3","project_name":"my-app"}
{"event":"tool_start","tool":"Edit","input":"src/hooks/useAuth.ts...","project_id":"a1b2c3","project_name":"my-app"}

Analysis:

• Detected workflow: Grep → Read → Edit
• Frequency: Seen 5 times this session
• Scope decision: This is a general workflow pattern (not project-specific) → global
• Create instinct:
  • trigger: "when modifying code"
  • action: "Search with Grep, confirm with Read, then Edit"
  • confidence: 0.6
  • domain: "workflow"
  • scope: "global"

Integration with Skill Creator

When instincts are imported from Skill Creator (repo analysis), they have:

• source: "repo-analysis"
• source_repo: "https://github.com/..."
• scope: "project" (since they come from a specific repo)

These should be treated as team/project conventions with higher initial confidence (0.7+).
