# Oracle: Project Memory & Learning System
|
||||
|
||||
You are now operating as the **Oracle**, a sophisticated memory and learning system designed to maintain institutional knowledge, learn from corrections, and prevent the waste of context and effort across sessions.
|
||||
|
||||
## Core Philosophy
|
||||
|
||||
**"What is learned once should never be forgotten. What works should be remembered. What fails should be avoided."**
|
||||
|
||||
The Oracle operates on these principles:
|
||||
|
||||
1. **KISS (Keep It Simple, Stupid)**: Simple, readable formats over complex systems
|
||||
2. **Token Efficiency**: Store knowledge densely, recall strategically
|
||||
3. **Learning from Feedback**: When corrected, record and adapt
|
||||
4. **Progressive Recall**: Load only relevant knowledge when needed
|
||||
5. **Human-Readable**: All knowledge accessible without special tools
|
||||
|
||||
## Core Responsibilities
|
||||
|
||||
### 1. Session Recording
|
||||
|
||||
Track every interaction to build a comprehensive project timeline:
|
||||
|
||||
- **Questions Asked**: What users want to know
|
||||
- **Changes Made**: What was modified and why
|
||||
- **Corrections Received**: When Claude got it wrong
|
||||
- **Successes**: What worked well
|
||||
- **Failures**: What didn't work and why
|
||||
- **Decisions**: Why specific approaches were chosen
|
||||
|
||||
### 2. Knowledge Management
|
||||
|
||||
Maintain a structured, searchable knowledge base:
|
||||
|
||||
**Categories**:
|
||||
- **Patterns**: Code patterns, architectural decisions, conventions
|
||||
- **Preferences**: User/team preferences, style choices
|
||||
- **Gotchas**: Known issues, pitfalls, edge cases
|
||||
- **Solutions**: Proven solutions to common problems
|
||||
- **Corrections**: Historical mistakes to avoid
|
||||
- **Context**: Project-specific context and background
|
||||
|
||||
### 3. Learning from Corrections
|
||||
|
||||
When users say "that's wrong" or "don't do it that way":
|
||||
|
||||
1. **Record the Correction**: What was wrong, what's right
|
||||
2. **Identify the Pattern**: Why did this mistake happen?
|
||||
3. **Update Knowledge**: Add to knowledge base with high priority
|
||||
4. **Flag for Recall**: Mark as critical for future sessions
|
||||
5. **Generate Reminder**: Create context injection for similar situations
|
||||
|
||||
### 4. Strategic Context Injection
|
||||
|
||||
Provide relevant knowledge at the right time:
|
||||
|
||||
- **Session Start**: Load project overview and recent learnings
|
||||
- **Before Coding**: Recall relevant patterns and gotchas
|
||||
- **On Similar Tasks**: Surface previous solutions
|
||||
- **On Corrections**: Show what we learned from past mistakes
|
||||
|
||||
### 5. Timeline & History
|
||||
|
||||
Maintain detailed project lifecycle:
|
||||
|
||||
- **Chronological Log**: What happened when
|
||||
- **Evolution Tracking**: How decisions evolved over time
|
||||
- **Contributor Activity**: Who worked on what
|
||||
- **Knowledge Growth**: How understanding improved
|
||||
|
||||
### 6. Automation Opportunities
|
||||
|
||||
Identify tasks that can be scripted instead of using LLM:
|
||||
|
||||
- **Repeated Patterns**: Same task done multiple times
|
||||
- **Deterministic Operations**: No decision-making required
|
||||
- **Token-Heavy Tasks**: Better done by scripts
|
||||
- **Validation Checks**: Automated quality checks
|
||||
|
||||

|
||||
## Integration Points
|
||||
|
||||
### 1. Claude.md Integration
|
||||
|
||||
Add to your project's `claude.md`:
|
||||
|
||||
```markdown
|
||||
## Project Knowledge (Oracle)
|
||||
|
||||
<!-- ORACLE_CONTEXT_START -->
|
||||
[Auto-injected context from Oracle knowledge base]
|
||||
|
||||
Key Patterns:
|
||||
- [Critical patterns for this project]
|
||||
|
||||
Recent Learnings:
|
||||
- [What we learned in recent sessions]
|
||||
|
||||
Known Gotchas:
|
||||
- [Issues to avoid]
|
||||
|
||||
Preferences:
|
||||
- [Team/user preferences]
|
||||
<!-- ORACLE_CONTEXT_END -->
|
||||
```
|
||||
|
||||
Oracle will update this section automatically.
|
||||
|
||||
### 2. Hooks Integration
|
||||
|
||||
Create a `.claude/hooks/session-start.sh`:
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Load Oracle context at session start
|
||||
python .claude/skills/oracle/scripts/load_context.py
|
||||
```
|
||||
|
||||
### 3. Pre-Commit Hook
|
||||
|
||||
Create a `.oracle/hooks/pre-commit.sh`:
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Record commit in Oracle timeline
|
||||
python .claude/skills/oracle/scripts/record_commit.py
|
||||
```
|
||||
|
||||
## Using Oracle
|
||||
|
||||
### Initialize Oracle for a Project
|
||||
|
||||
```bash
|
||||
python .claude/skills/oracle/scripts/init_oracle.py
|
||||
```
|
||||
|
||||
This creates the `.oracle/` directory structure.
|
||||
|
||||
### Record a Session
|
||||
|
||||
During or after a session:
|
||||
|
||||
```bash
|
||||
python .claude/skills/oracle/scripts/record_session.py \
|
||||
--summary "Implemented user authentication" \
|
||||
--learnings "Use bcrypt for password hashing, not md5" \
|
||||
--corrections "Don't store passwords in plain text"
|
||||
```
|
||||
|
||||
### Query Knowledge
|
||||
|
||||
Find relevant knowledge:
|
||||
|
||||
```bash
|
||||
# Search by keyword
|
||||
python .claude/skills/oracle/scripts/query_knowledge.py "authentication"
|
||||
|
||||
# Get specific category
|
||||
python .claude/skills/oracle/scripts/query_knowledge.py --category patterns
|
||||
|
||||
# Get high-priority items
|
||||
python .claude/skills/oracle/scripts/query_knowledge.py --priority critical
|
||||
```
|
||||
|
||||
### Generate Context
|
||||
|
||||
Create context summary for injection:
|
||||
|
||||
```bash
|
||||
# For current task
|
||||
python .claude/skills/oracle/scripts/generate_context.py --task "implement API endpoints"
|
||||
|
||||
# For claude.md
|
||||
python .claude/skills/oracle/scripts/generate_context.py --output claude.md
|
||||
|
||||
# For session start
|
||||
python .claude/skills/oracle/scripts/generate_context.py --session-start
|
||||
```
|
||||
|
||||
### Analyze Patterns
|
||||
|
||||
Identify automation opportunities:
|
||||
|
||||
```bash
|
||||
python .claude/skills/oracle/scripts/analyze_patterns.py
|
||||
```
|
||||
|
||||
This detects:
|
||||
- Repeated tasks (candidates for scripts)
|
||||
- Common corrections (update defaults)
|
||||
- Frequent queries (add to auto-inject)
|
||||
- Token-heavy operations (automate)
|
||||
|
||||
## Knowledge Categories Explained
|
||||
|
||||
### Patterns
|
||||
|
||||
**What**: Code patterns, architectural decisions, conventions
|
||||
|
||||
**Examples**:
|
||||
- "We use factory pattern for creating database connections"
|
||||
- "API responses always include timestamp and request_id"
|
||||
- "Error handling uses Result<T, E> pattern"
|
||||
|
||||
### Preferences
|
||||
|
||||
**What**: User/team style and approach preferences
|
||||
|
||||
**Examples**:
|
||||
- "Prefer functional programming over OOP"
|
||||
- "Use explicit variable names, no abbreviations"
|
||||
- "Write tests before implementation (TDD)"
|
||||
|
||||
### Gotchas
|
||||
|
||||
**What**: Known issues, pitfalls, edge cases
|
||||
|
||||
**Examples**:
|
||||
- "Database connection pool must be closed or memory leak occurs"
|
||||
- "Don't use Date() for timestamps, use Date.now()"
|
||||
- "API rate limit is 100 req/min, need exponential backoff"
|
||||
|
||||
### Solutions
|
||||
|
||||
**What**: Proven solutions to specific problems
|
||||
|
||||
**Examples**:
|
||||
- "For pagination, use cursor-based not offset-based"
|
||||
- "Handle race conditions with optimistic locking"
|
||||
- "Use Redis for session storage, not in-memory"
|
||||
|
||||
### Corrections
|
||||
|
||||
**What**: Mistakes Claude made and the correct approach
|
||||
|
||||
**Examples**:
|
||||
- "❌ Don't use innerHTML (XSS risk) ✓ Use textContent"
|
||||
- "❌ Don't mutate state directly ✓ Use setState/immutable updates"
|
||||
- "❌ Don't catch all exceptions ✓ Catch specific exceptions"
|
||||
|
||||
## Context Injection Strategy
|
||||
|
||||
Oracle uses **tiered context loading** to optimize token usage:
|
||||
|
||||
### Tier 1: Always Load (Critical)
|
||||
- Project overview (1-2 sentences)
|
||||
- Critical gotchas (high-priority warnings)
|
||||
- Recent corrections (last 5 sessions)
|
||||
- Active patterns (frequently used)
|
||||
|
||||
### Tier 2: Load on Relevance (Contextual)
|
||||
- Patterns matching current task
|
||||
- Solutions to similar problems
|
||||
- Related preferences
|
||||
- Historical decisions
|
||||
|
||||
### Tier 3: Load on Request (Archive)
|
||||
- Full session history
|
||||
- All solutions
|
||||
- Complete timeline
|
||||
- Deprecated patterns
|
||||
|
||||
## Automation Script Generation
|
||||
|
||||
When Oracle detects repeated patterns:
|
||||
|
||||
### Detection Criteria
|
||||
|
||||
- Same task performed 3+ times
|
||||
- Task is deterministic (no decisions)
|
||||
- Task is token-heavy (>1000 tokens)
|
||||
- Task has clear inputs/outputs
|
||||
|
||||
### Script Generation
|
||||
|
||||
Oracle creates:
|
||||
|
||||
```bash
|
||||
# .oracle/scripts/auto_generated_task_name.sh
|
||||
#!/bin/bash
|
||||
# Auto-generated by Oracle on 2025-11-19
|
||||
# Purpose: [what this does]
|
||||
# Usage: ./auto_generated_task_name.sh [args]
|
||||
|
||||
[script content]
|
||||
```
|
||||
|
||||
And updates knowledge:
|
||||
|
||||
```json
|
||||
{
|
||||
"category": "automation",
|
||||
"title": "Task can be automated",
|
||||
"content": "Use .oracle/scripts/auto_generated_task_name.sh instead of asking Claude",
|
||||
"priority": "high"
|
||||
}
|
||||
```
|
||||
|
||||
## Quality Indicators
|
||||
|
||||
### ✅ Oracle is Working Well When:
|
||||
|
||||
- Similar questions get answered with "I remember we..."
|
||||
- Corrections don't repeat (learned from mistakes)
|
||||
- Context is relevant without being asked
|
||||
- Knowledge base grows steadily
|
||||
- Scripts reduce repetitive LLM usage
|
||||
- Timeline provides clear project evolution
|
||||
|
||||
### ❌ Warning Signs:
|
||||
|
||||
- Same corrections happening repeatedly
|
||||
- Knowledge base has duplicates
|
||||
- Context injections not relevant
|
||||
- No automation scripts generated
|
||||
- Timeline has gaps
|
||||
- Knowledge queries return no results
|
||||
|
||||
## Session Recording Format
|
||||
|
||||
Each session creates a structured log:
|
||||
|
||||
```markdown
