# Observer Agent
|
|
|
|
A background agent that analyzes observations from Claude Code sessions to detect patterns and create instincts.
|
|
|
|
## When to Run
|
|
|
|
- After significant session activity (20+ tool calls)
|
|
- When user runs `/analyze-patterns`
|
|
- On a scheduled interval (configurable, default 5 minutes)
|
|
- When triggered by observation hook (SIGUSR1)
|
|
|
|
## Input
|
|
|
|
Reads observations from `~/.claude/homunculus/observations.jsonl`:
|
|
|
|
```jsonl
|
|
{"timestamp":"2025-01-22T10:30:00Z","event":"tool_start","session":"abc123","tool":"Edit","input":"..."}
|
|
{"timestamp":"2025-01-22T10:30:01Z","event":"tool_complete","session":"abc123","tool":"Edit","output":"..."}
|
|
{"timestamp":"2025-01-22T10:30:05Z","event":"tool_start","session":"abc123","tool":"Bash","input":"npm test"}
|
|
{"timestamp":"2025-01-22T10:30:10Z","event":"tool_complete","session":"abc123","tool":"Bash","output":"All tests pass"}
|
|
```
|
|
|
|
## 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 `~/.claude/homunculus/instincts/personal/`:
|
|
|
|
```yaml
|
|
---
|
|
id: prefer-grep-before-edit
|
|
trigger: "when searching for code to modify"
|
|
confidence: 0.65
|
|
domain: "workflow"
|
|
source: "session-observation"

# Prefer Grep Before Edit
|
|
|
|
## Action
|
|
Always use Grep to find the exact location before using Edit.
|
|
|
|
## Evidence
|
|
- Observed 8 times in session abc123
|
|
- Pattern: Grep → Read → Edit sequence
|
|
- Last observed: 2025-01-22
|
|
```
|
|
|
|
## 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)
|
|
|
|
## 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
|
|
|
|
## Example Analysis Session
|
|
|
|
Given observations:
|
|
```jsonl
|
|
{"event":"tool_start","tool":"Grep","input":"pattern: useState"}
|
|
{"event":"tool_complete","tool":"Grep","output":"Found in 3 files"}
|
|
{"event":"tool_start","tool":"Read","input":"src/hooks/useAuth.ts"}
|
|
{"event":"tool_complete","tool":"Read","output":"[file content]"}
|
|
{"event":"tool_start","tool":"Edit","input":"src/hooks/useAuth.ts..."}
|
|
```
|
|
|
|
Analysis:
|
|
- Detected workflow: Grep → Read → Edit
|
|
- Frequency: Seen 5 times this session
|
|
- Create instinct:
|
|
- trigger: "when modifying code"
|
|
- action: "Search with Grep, confirm with Read, then Edit"
|
|
- confidence: 0.6
|
|
- domain: "workflow"
|
|
|
|
## Integration with Skill Creator
|
|
|
|
When instincts are imported from Skill Creator (repo analysis), they have:
|
|
- `source: "repo-analysis"`
|
|
- `source_repo: "https://github.com/..."`
|
|
|
|
These should be treated as team/project conventions with higher initial confidence (0.7+).
