refactor: simplify agent execution philosophy and reorganize context structure

Major Changes:
- Simplified OpenAgent execution philosophy (universal agent, delegate sparingly)
- Reorganized context into 3-tier structure: standards/, workflows/, system/
- Improved approval gate wording for clarity
- Enhanced .gitignore with comprehensive Node.js patterns
- Added comprehensive plugin development guide

Context Reorganization:
- Consolidated scattered files into organized structure with Quick Reference sections
- Emphasis on lazy loading for token efficiency (60-80% token savings)
- New standards: code.md, docs.md, tests.md, patterns.md, analysis.md
- New workflows: delegation.md, sessions.md, task-breakdown.md, review.md
- New system: context-guide.md (master reference)

Delegation Improvements:
- Removed complex XML-style routing rules
- Simplified to clear when/how structure with 7 delegation criteria
- Added Perspective and Simulation as delegation triggers
- Clearer delegation template and process

Documentation Enhancements:
- Added building-plugins.md (1,274 lines - comprehensive plugin guide)
- Updated how-context-works.md with research-backed architecture
- Enhanced slash-commands-and-subagents.md with path resolution findings

Content Preservation:
- context-discovery.md → system/context-guide.md + workflows/sessions.md
- context-management.md → workflows/sessions.md
- essential-patterns.md → standards/patterns.md
- session-management.md → workflows/sessions.md

# Context Discovery
## Purpose
**Dynamically load relevant context files when delegating to subagents**
Allows subagents to discover and access context created earlier in the session, preventing information loss across delegation boundaries.
## How It Works
### 1. Context File Creation
When creating a context file, add metadata to manifest:
```json
"context_files": {
"features/user-auth-context.md": {
"created": "2025-01-18T14:30:22Z",
"for": "@subagents/core/task-manager",
"keywords": ["user-auth", "authentication", "features"]
}
}
```
**Metadata Fields**:
- `created`: Timestamp of file creation
- `for`: Target subagent (which agent will use this)
- `keywords`: Array of searchable keywords for discovery
### 2. Context Indexing
Manifest maintains keyword index for fast lookup:
```json
"context_index": {
"user-auth": [
"features/user-auth-context.md",
"tasks/user-auth-tasks.md"
],
"api": [
"documentation/api-docs-context.md"
]
}
```
**Index Structure**:
- Key: Keyword (from context file metadata)
- Value: Array of file paths containing that keyword
### 3. Context Discovery Process
When delegating to subagent:
1. **Extract keywords** from user request or task context
2. **Search manifest** `context_index` for matching keywords
3. **Find related files** by category or keyword match
4. **Pass file paths** to subagent in delegation prompt
5. **Subagent reads** context files as needed
### 4. Delegation Pattern
**Context Reference Format**:
```
Related context available at: .tmp/sessions/{session-id}/features/user-auth-context.md
```
**Full Delegation Example**:
```
Delegating to @subagents/code/coder-agent:
"Implement user authentication login component.
Related context available at:
- .tmp/sessions/20250118-143022-a4f2/features/user-auth-context.md
- .tmp/sessions/20250118-143022-a4f2/tasks/user-auth-tasks.md
Read these files for full context on requirements and task breakdown."
```
## When to Create Context Files
**Only create when ALL of these apply**:
- Delegating to a subagent
- Context description is verbose (>2 sentences) OR
- Risk of misinterpretation without detailed context
**Don't create for**:
- Simple, one-line instructions
- Direct execution (no delegation)
- Conversational questions
## Context File Categories
```
features/ - Feature development context
documentation/ - Documentation tasks
code/ - Code-related tasks
refactoring/ - Refactoring tasks
testing/ - Testing tasks
tasks/ - Task breakdowns created by task-manager
general/ - General tasks that don't fit other categories
```
## Context File Template
```markdown
# Context: {Task Name}
Session: {session-id}
## Request Summary
[Brief description of what needs to be done]
## Background
[Relevant context and information]
## Expected Output
[What the subagent should produce]
## Constraints
[Any limitations or requirements]
## Related Context
[Links to other context files if applicable]
```
## Discovery Strategies
### By Keyword
Search `context_index` for exact keyword matches:
```
User: "Add login validation"
Keywords: ["login", "validation", "user-auth"]
→ Finds: features/user-auth-context.md, tasks/user-auth-tasks.md
```
### By Category
Search `context_files` for matching category:
```
Delegating to @documentation agent
Category: "documentation"
→ Finds all files in documentation/ folder
```
### By Target Agent
Search `context_files` for files created for specific agent:
```
Delegating to @task-manager
Filter: "for": "@subagents/core/task-manager"
→ Finds all context files created for task-manager
```
## Example Workflow
```
1. User: "Build user authentication system"
→ OpenAgent creates: features/user-auth-context.md
→ Manifest updated with keywords: ["user-auth", "authentication", "features"]
→ Delegates to @task-manager with context file path
2. Task-manager creates: tasks/user-auth-tasks.md
→ Manifest updated with keywords: ["user-auth", "tasks", "breakdown"]
→ Both files now indexed under "user-auth"
3. User: "Implement the login component"
→ OpenAgent searches manifest for "user-auth" OR "login"
→ Finds: features/user-auth-context.md, tasks/user-auth-tasks.md
→ Delegates to @coder-agent with references to BOTH files
→ Coder-agent reads both files to understand full context
4. User: "Add password reset feature"
→ OpenAgent searches manifest for "user-auth" OR "password"
→ Finds existing user-auth context
→ Creates new: features/password-reset-context.md
→ Links to existing user-auth context
→ Delegates with all related context files
```
## Benefits
✅ **No context loss**: Information persists across subagent calls
✅ **Automatic discovery**: Related context found by keywords
✅ **Flexible**: Subagents read only what they need
✅ **Traceable**: Manifest shows all context relationships
✅ **Scalable**: Works with multiple context files per session
✅ **Reusable**: Later tasks can reference earlier context
## Context Inheritance
**Load related context files from manifest before delegating**
When delegating to a subagent:
1. Check if session exists
2. Read manifest if available
3. Search for related context by keyword/category
4. Include relevant context file paths in delegation
5. Subagent reads context files as first step
This ensures subagents have full context from earlier in the session.
## Error Handling
### Manifest Not Found
- Session not initialized yet
- Continue without context discovery
- Create new session if context file needed
### Context File Missing
- File was deleted or moved
- Warn user about missing context
- Continue with available context
- Update manifest to remove missing file
### Keyword Collision
- Multiple files match same keyword
- Include all matching files in delegation
- Let subagent determine relevance
- Consider more specific keywords in future
## Best Practices
1. **Use specific keywords**: "user-auth" better than "auth"
2. **Include category in keywords**: ["features", "user-auth"]
3. **Link related context**: Reference other context files
4. **Update manifest immediately**: Don't delay indexing
5. **Clean up stale context**: Remove when task complete
6. **Validate file exists**: Before passing to subagent

# Context Management Strategy
## Session-Based Isolation
### Purpose
Prevent concurrent agent instances from interfering with each other by using isolated session folders.
### Session Structure
```
.tmp/sessions/{session-id}/{task-category}/{task-name}-context.md
```
### Session ID Format
`{timestamp}-{random-4-chars}`
Example: `20250118-143022-a4f2`
### Session Manifest
Each session has a manifest file tracking all context files:
**Location**: `.tmp/sessions/{session-id}/.manifest.json`
**Structure**:
```json
{
"session_id": "20250118-143022-a4f2",
"created_at": "2025-01-18T14:30:22Z",
"last_activity": "2025-01-18T14:35:10Z",
"context_files": {
"features/user-auth-context.md": {
"created": "2025-01-18T14:30:22Z",
"for": "@subagents/core/task-manager",
"keywords": ["user-auth", "authentication", "features"]
},
"tasks/user-auth-tasks.md": {
"created": "2025-01-18T14:32:15Z",
"for": "@subagents/core/task-manager",
"keywords": ["user-auth", "tasks", "breakdown"]
},
"documentation/api-docs-context.md": {
"created": "2025-01-18T14:35:10Z",
"for": "@subagents/core/documentation",
"keywords": ["api", "documentation"]
}
},
"context_index": {
"user-auth": [
"features/user-auth-context.md",
"tasks/user-auth-tasks.md"
],
"api": [
"documentation/api-docs-context.md"
]
}
}
```
## Temporary Context Files
### When to Create
Only create context files when **ALL** of these apply:
- Delegating to a subagent
- Context description is verbose (>2 sentences) OR
- Risk of misinterpretation without detailed context
### File Structure
```
.tmp/sessions/{session-id}/{task-category}/{task-name}-context.md
```
### Categories
- `features/` - Feature development context
- `documentation/` - Documentation tasks
- `code/` - Code-related tasks
- `refactoring/` - Refactoring tasks
- `testing/` - Testing tasks
- `tasks/` - Task breakdowns created by task-manager
- `general/` - General tasks that don't fit other categories
### Examples
```
.tmp/sessions/20250118-143022-a4f2/features/user-auth-context.md
.tmp/sessions/20250118-143022-a4f2/documentation/api-docs-context.md
.tmp/sessions/20250118-150000-b7k9/code/database-refactor-context.md
.tmp/sessions/20250118-151500-c3x8/testing/integration-tests-context.md
```
### File Contents
```markdown
# Context: {Task Name}
Session: {session-id}
## Request Summary
[Brief description of what needs to be done]
## Background
[Relevant context and information]
## Expected Output
[What the subagent should produce]
## Constraints
[Any limitations or requirements]
```
## Cleanup Strategy
### During Session
1. Remove individual context files after task completion
2. Update manifest to remove file entry
3. Update `last_activity` timestamp
### End of Session
1. Remove entire session folder: `.tmp/sessions/{session-id}/`
2. Only delete files tracked in current session's manifest
### Stale Session Cleanup
- Automatically clean sessions older than 24 hours with no activity
- Check `last_activity` timestamp in manifest
- Safe to run periodically without affecting active sessions
### Manual Cleanup
Users can safely delete:
- Entire `.tmp/` folder anytime
- Individual session folders
- Stale sessions (check `last_activity` timestamp)
## Concurrent Safety
### Isolation Guarantees
✅ Each agent instance has unique session ID
✅ Context files are isolated per session
✅ Manifest tracks only files created by this session
✅ Cleanup only affects current session's files
✅ No risk of deleting another instance's context
### Best Practices
1. **Generate session ID early** - At first context file creation
2. **Track all files** - Add every context file to manifest
3. **Update activity** - Touch `last_activity` on each operation
4. **Clean up promptly** - Remove files after task completion
5. **Only clean own files** - Never delete files outside current session
## Dynamic Context Loading
### Purpose
Allow subagents to discover and load relevant context files created earlier in the session.
### How It Works
**1. Context File Creation**
When creating a context file, add metadata to manifest:
```json
"context_files": {
"features/user-auth-context.md": {
"created": "2025-01-18T14:30:22Z",
"for": "@subagents/core/task-manager",
"keywords": ["user-auth", "authentication", "features"]
}
}
```
**2. Context Indexing**
Manifest maintains keyword index for fast lookup:
```json
"context_index": {
"user-auth": [
"features/user-auth-context.md",
"tasks/user-auth-tasks.md"
]
}
```
**3. Context Discovery**
When delegating to subagent:
1. Search manifest for related context files (by keyword/category)
2. Pass relevant context file paths to subagent
3. Subagent reads context files as needed
**4. Delegation Pattern**
```
Delegating to @subagents/code/coder-agent:
"Implement user authentication login component.
Related context available at:
- .tmp/sessions/20250118-143022-a4f2/features/user-auth-context.md
- .tmp/sessions/20250118-143022-a4f2/tasks/user-auth-tasks.md
Read these files for full context on requirements and task breakdown."
```
### Example Workflow
```
1. User: "Build user authentication system"
→ OpenAgent creates: features/user-auth-context.md
→ Delegates to @task-manager
2. Task-manager creates: tasks/user-auth-tasks.md
→ Both files tracked in manifest with keyword "user-auth"
3. User: "Implement the login component"
→ OpenAgent searches manifest for "user-auth" context
→ Finds both context files
→ Delegates to @coder-agent with references to both files
→ Coder-agent reads files to understand full context
```
### Benefits
- **No context loss**: Information persists across subagent calls
- **Automatic discovery**: Related context found by keywords
- **Flexible**: Subagents read only what they need
- **Traceable**: Manifest shows all context relationships
---
## Why This Approach?
### Session Isolation
- **Concurrent safety**: Multiple agents can run simultaneously
- **No conflicts**: Each session has its own namespace
- **Easy cleanup**: Delete entire session folder when done
- **Traceable**: Manifest shows what belongs to each session
### Dynamic Context
- **Discoverable**: Context files indexed by keywords
- **Reusable**: Later subagents can access earlier context
- **Flexible**: Load only relevant context
- **Persistent**: Context survives across subagent calls
### Why `.tmp/sessions/`?
- Standard `.tmp/` convention (commonly ignored)
- `sessions/` subfolder makes purpose clear
- Session ID provides unique namespace
- Easy to identify and clean up stale sessions
- Hidden folder (starts with `.`)
## Example Workflow
```bash
# Agent Instance 1 starts
Session ID: 20250118-143022-a4f2
Creates: .tmp/sessions/20250118-143022-a4f2/features/user-auth-context.md
# Agent Instance 2 starts (concurrent)
Session ID: 20250118-143030-b7k9
Creates: .tmp/sessions/20250118-143030-b7k9/features/payment-context.md
# Both agents work independently without conflicts
# Agent Instance 1 completes
Deletes: .tmp/sessions/20250118-143022-a4f2/ (entire folder)
# Agent Instance 2 continues unaffected
Still has: .tmp/sessions/20250118-143030-b7k9/

# Code Standards
## Quick Reference
**Core Philosophy**: Modular, Functional, Maintainable
**Golden Rule**: If you can't easily test it, refactor it
**Critical Patterns** (use these):
- ✅ Pure functions (same input = same output, no side effects)
- ✅ Immutability (create new data, don't modify)
- ✅ Composition (build complex from simple)
- ✅ Small functions (< 50 lines)
- ✅ Explicit dependencies (dependency injection)
**Anti-Patterns** (avoid these):
- ❌ Mutation, side effects, deep nesting
- ❌ God modules, global state, large functions
---
## Core Philosophy
**Modular**: Everything is a component - small, focused, reusable
**Functional**: Pure functions, immutability, composition over inheritance
**Maintainable**: Self-documenting, testable, predictable
## Principles
### Modular Design
- Single responsibility per module
- Clear interfaces (explicit inputs/outputs)
- Independent and composable
- < 100 lines per component (ideally < 50)
### Functional Approach
- **Pure functions**: Same input = same output, no side effects
- **Immutability**: Create new data, don't modify existing
- **Composition**: Build complex from simple functions
- **Declarative**: Describe what, not how
### Component Structure
```
component/
├── index.js # Public interface
├── core.js # Core logic (pure functions)
├── utils.js # Helpers
└── tests/ # Tests
```
## Patterns
### Pure Functions
```javascript
// ✅ Pure
const add = (a, b) => a + b;
const formatUser = (user) => ({ ...user, fullName: `${user.firstName} ${user.lastName}` });
// ❌ Impure (side effects)
let total = 0;
const addToTotal = (value) => { total += value; return total; };
```
### Immutability
```javascript
// ✅ Immutable
const addItem = (items, item) => [...items, item];
const updateUser = (user, changes) => ({ ...user, ...changes });
// ❌ Mutable
const addItem = (items, item) => { items.push(item); return items; };
```
### Composition
```javascript
// ✅ Compose small functions
const processUser = pipe(validateUser, enrichUserData, saveUser);
const isValidEmail = (email) => validateEmail(normalizeEmail(email));
// ❌ Deep inheritance
class ExtendedUserManagerWithValidation extends UserManager { }
```
### Declarative
```javascript
// ✅ Declarative
const activeUsers = users.filter(u => u.isActive).map(u => u.name);
// ❌ Imperative
const names = [];
for (let i = 0; i < users.length; i++) {
if (users[i].isActive) names.push(users[i].name);
}
```
## Naming
- **Files**: lowercase-with-dashes.js
- **Functions**: verbPhrases (getUser, validateEmail)
- **Predicates**: isValid, hasPermission, canAccess
- **Variables**: descriptive (userCount not uc), const by default
- **Constants**: UPPER_SNAKE_CASE
## Error Handling
```javascript
// ✅ Explicit error handling
function parseJSON(text) {
try {
return { success: true, data: JSON.parse(text) };
} catch (error) {
return { success: false, error: error.message };
}
}
// ✅ Validate at boundaries
function createUser(userData) {
const validation = validateUserData(userData);
if (!validation.isValid) {
return { success: false, errors: validation.errors };
}
return { success: true, user: saveUser(userData) };
}
```
## Dependency Injection
```javascript
// ✅ Dependencies explicit
function createUserService(database, logger) {
return {
createUser: (userData) => {
logger.info('Creating user');
return database.insert('users', userData);
}
};
}
// ❌ Hidden dependencies
import db from './database.js';
function createUser(userData) { return db.insert('users', userData); }
```
## Anti-Patterns
❌ **Mutation**: Modifying data in place
❌ **Side effects**: console.log, API calls in pure functions
❌ **Deep nesting**: Use early returns instead
❌ **God modules**: Split into focused modules
❌ **Global state**: Pass dependencies explicitly
❌ **Large functions**: Keep < 50 lines
## Best Practices
✅ Pure functions whenever possible
✅ Immutable data structures
✅ Small, focused functions (< 50 lines)
✅ Compose small functions into larger ones
✅ Explicit dependencies (dependency injection)
✅ Validate at boundaries
✅ Self-documenting code
✅ Test in isolation
**Golden Rule**: If you can't easily test it, refactor it.

# Documentation Standards
## Quick Reference
**Golden Rule**: If users ask the same question twice, document it
**Document** (✅ DO):
- WHY decisions were made
- Complex algorithms/logic
- Public APIs, setup, common use cases
**Don't Document** (❌ DON'T):
- Obvious code (i++ doesn't need comment)
- What code does (should be self-explanatory)
**Principles**: Audience-focused, Show don't tell, Keep current
---
## Principles
**Audience-focused**: Write for users (what/how), developers (why/when), contributors (setup/conventions)
**Show, don't tell**: Code examples, real use cases, expected output
**Keep current**: Update with code changes, remove outdated info, mark deprecations
## README Structure
```markdown
# Project Name
Brief description (1-2 sentences)
## Features
- Key feature 1
- Key feature 2
## Installation
```bash
npm install package-name
```
## Quick Start
```javascript
const result = doSomething();
```
## Usage
[Detailed examples]
## API Reference
[If applicable]
## Contributing
[Link to CONTRIBUTING.md]
## License
[License type]
```
## Function Documentation
```javascript
/**
* Calculate total price including tax
*
* @param {number} price - Base price
* @param {number} taxRate - Tax rate (0-1)
* @returns {number} Total with tax
*
* @example
* calculateTotal(100, 0.1) // 110
*/
function calculateTotal(price, taxRate) {
return price * (1 + taxRate);
}
```
## What to Document
### ✅ DO
- **WHY** decisions were made
- Complex algorithms/logic
- Non-obvious behavior
- Public APIs
- Setup/installation
- Common use cases
- Known limitations
- Workarounds (with explanation)
### ❌ DON'T
- Obvious code (i++ doesn't need comment)
- What code does (should be self-explanatory)
- Redundant information
- Outdated/incorrect info
## Comments
### Good
```javascript
// Calculate discount by tier (Bronze: 5%, Silver: 10%, Gold: 15%)
const discount = getDiscountByTier(customer.tier);
// HACK: API returns null instead of [], normalize it
const items = response.items || [];
// TODO: Use async/await when Node 18+ is minimum
```
### Bad
```javascript
// Increment i
i++;
// Get user
const user = getUser();
```
## API Documentation
```markdown
### POST /api/users
Create a new user
**Request:**
```json
{ "name": "John", "email": "john@example.com" }
```
**Response:**
```json
{ "id": "123", "name": "John", "email": "john@example.com" }
```
**Errors:**
- 400 - Invalid input
- 409 - Email exists
```
## Best Practices
✅ Explain WHY, not just WHAT
✅ Include working examples
✅ Show expected output
✅ Cover error handling
✅ Use consistent terminology
✅ Keep structure predictable
✅ Update when code changes
**Golden Rule**: If users ask the same question twice, document it.

# Testing Standards
## Quick Reference
**Golden Rule**: If you can't test it easily, refactor it
**AAA Pattern**: Arrange → Act → Assert
**Test** (✅ DO):
- Happy path, edge cases, error cases
- Business logic, public APIs
**Don't Test** (❌ DON'T):
- Third-party libraries, framework internals
- Simple getters/setters, private details
**Coverage**: Critical (100%), High (90%+), Medium (80%+)
---
## Principles
**Test behavior, not implementation**: Focus on what code does, not how
**Keep tests simple**: One assertion per test, clear names, minimal setup
**Independent tests**: No shared state, run in any order
**Fast and reliable**: Quick execution, no flaky tests, deterministic
## Test Structure (AAA Pattern)
```javascript
test('calculateTotal returns sum of item prices', () => {
// Arrange - Set up test data
const items = [{ price: 10 }, { price: 20 }, { price: 30 }];
// Act - Execute code
const result = calculateTotal(items);
// Assert - Verify result
expect(result).toBe(60);
});
```
## What to Test
### ✅ DO Test
- Happy path (normal usage)
- Edge cases (boundaries, empty, null, undefined)
- Error cases (invalid input, failures)
- Business logic (core functionality)
- Public APIs (exported functions)
### ❌ DON'T Test
- Third-party libraries
- Framework internals
- Simple getters/setters
- Private implementation details
## Coverage Goals
1. **Critical**: Business logic, data transformations (100%)
2. **High**: Public APIs, user-facing features (90%+)
3. **Medium**: Utilities, helpers (80%+)
4. **Low**: Simple wrappers, configs (optional)
## Testing Pure Functions
```javascript
function add(a, b) { return a + b; }
test('add returns sum', () => {
expect(add(2, 3)).toBe(5);
expect(add(-1, 1)).toBe(0);
expect(add(0, 0)).toBe(0);
});
```
## Testing with Dependencies
```javascript
// Testable with dependency injection
function createUserService(database) {
return {
getUser: (id) => database.findById('users', id)
};
}
// Test with mock
test('getUser retrieves from database', () => {
const mockDb = {
findById: jest.fn().mockReturnValue({ id: 1, name: 'John' })
};
const service = createUserService(mockDb);
const user = service.getUser(1);
expect(mockDb.findById).toHaveBeenCalledWith('users', 1);
expect(user).toEqual({ id: 1, name: 'John' });
});
```
## Test Naming
```javascript
// ✅ Good: Descriptive, clear expectation
test('calculateDiscount returns 10% off for premium users', () => {});
test('validateEmail returns false for invalid format', () => {});
test('createUser throws error when email exists', () => {});
// ❌ Bad: Vague, unclear
test('it works', () => {});
test('test user', () => {});
```
## Best Practices
✅ Test one thing per test
✅ Use descriptive test names
✅ Keep tests independent
✅ Mock external dependencies
✅ Test edge cases and errors
✅ Make tests readable
✅ Run tests frequently
✅ Fix failing tests immediately
**Golden Rule**: If you can't test it easily, refactor it.

# Context System Guide
## Quick Reference
**Golden Rule**: Fetch context when needed, not before (lazy loading)
**Key Principle**: Reference files WITHOUT @ symbol - agent fetches only when needed
**Structure**: standards/ (quality + analysis), workflows/ (process + review), system/ (internals)
**Session Location**: `.tmp/sessions/{timestamp}-{task-slug}/context.md`
---
## Overview
Context files provide guidelines and templates for specific tasks. Use lazy loading (fetch when needed) to keep prompts lean.
## Available Context Files
All files are in `.opencode/context/core/` with organized subfolders:
### Standards (Quality Guidelines + Analysis)
- `.opencode/context/core/standards/code.md` - Modular, functional code principles
- `.opencode/context/core/standards/docs.md` - Documentation standards
- `.opencode/context/core/standards/tests.md` - Testing standards
- `.opencode/context/core/standards/patterns.md` - Core patterns (error handling, security)
- `.opencode/context/core/standards/analysis.md` - Analysis framework
### Workflows (Process Templates + Review)
- `.opencode/context/core/workflows/delegation.md` - Delegation template
- `.opencode/context/core/workflows/task-breakdown.md` - Complex task breakdown
- `.opencode/context/core/workflows/sessions.md` - Session lifecycle
- `.opencode/context/core/workflows/review.md` - Code review guidelines
## Lazy Loading (Recommended)
Reference files **WITHOUT** `@` symbol - agent fetches only when needed:
```markdown
"Write code following .opencode/context/core/standards/code.md"
"Review using .opencode/context/core/workflows/review.md"
"Break down task using .opencode/context/core/workflows/task-breakdown.md"
```
**Benefits:**
- No prompt bloat
- Fetch only what's relevant
- Faster for simple tasks
- Agent decides when to load
## When to Use Each File
### .opencode/context/core/standards/code.md
- Writing new code
- Modifying existing code
- Following modular/functional patterns
- Making architectural decisions
### .opencode/context/core/standards/docs.md

## Temporary Context (Session-Specific)
When delegating, create focused task context:
**Location**: `.tmp/sessions/{timestamp}-{task-slug}/context.md`
**Structure**:
```markdown
# Task Context: {Task Name}
Session ID: {id}
Created: {timestamp}
Status: in_progress
## Current Request
{What user asked for}
## Requirements
- {requirement 1}
- {requirement 2}
## Decisions Made
- {decision 1}
## Files to Modify/Create
- {file 1} - {purpose}
## Static Context Available
- .opencode/context/core/standards/code.md
- .opencode/context/core/standards/tests.md
## Constraints/Notes
{Important context}
## Progress
- [ ] {task 1}
- [ ] {task 2}
---
**Instructions for Subagent:**
{Specific instructions}
```
## Session Management
### Session Structure
```
.tmp/sessions/{session-id}/
├── context.md # Task context
├── notes.md # Working notes
└── artifacts/ # Generated files
```
### Session ID Format
`{timestamp}-{random-4-chars}`
Example: `20250119-143022-a4f2`
### Cleanup
- Ask user before deleting session files
- Remove after task completion
- Keep if user wants to review
## Best Practices
✅ Use lazy loading (no @ symbol)
✅ Fetch only relevant context
✅ Create temp context when delegating
✅ Clean up sessions after completion
✅ Reference specific sections when possible
✅ Keep temp context focused and concise
**Golden Rule**: Fetch context when needed, not before.

# Session Management
## Quick Reference
**Key Principle**: Lazy initialization - only create when needed
**Session ID**: `{timestamp}-{random-4-chars}` (e.g., `20250118-143022-a4f2`)
**Cleanup**: Always ask user confirmation before deleting
**Safety**: NEVER delete outside current session, ONLY delete tracked files, ALWAYS confirm
---
## Lazy Initialization
**Only create session when first context file needed**

- If larger, break it down further
- Each task should be completable in one sitting
### Make Dependencies Clear
- Explicitly state what must be done first
- Identify parallel work opportunities
- Note blocking dependencies
### Include Verification
- How do you know the task is done?
- What should work when complete?
- How can it be tested?
### Be Realistic with Estimates
- Include time for testing
- Account for unknowns
- Add buffer for complexity
- Better to overestimate than underestimate
### Group Related Work
- Organize by feature or component
- Keep related tasks together
- Make phases logical and cohesive
## Common Patterns
### Database-First Pattern
1. Design schema

## File References with `@` Symbol
### Immediate vs. Lazy Loading
**With `@` symbol** - **Immediate Loading**:
- File is fetched and loaded right away
- Content is immediately available to the agent
- Use when context is always needed
**Without `@` symbol** - **Lazy Loading**:
- File is only fetched when the agent determines it's needed
- Saves tokens if the agent can complete the task without it
- Agent discovers and loads the file on-demand
### Using the `@` Symbol
**In commands and templates:**
```bash

3. Otherwise → resolve relative to repo root (`Instance.worktree`)
4. If not found → look for agent with that name
### Best Practices for Lazy Loading (Without `@`)
When referencing files without the `@` symbol, help the agent discover them by:
**1. Provide clear file paths**
```
"Use the context from .opencode/command/commit.md if needed"
```
**2. Describe what's there** (so agent knows when to fetch)
```
"Check the commit command guidelines in .opencode/command/commit.md
when you need to understand our commit message format"
```
**3. Mention directory conventions**
```
"Command templates are in .opencode/command/ - reference them as needed"
```
**4. Reference by purpose, not just path**
```
"Follow our commit guidelines (available in the command directory)
when making commits"
```
### Example: Lazy Loading in Practice
**Without `@` symbol (lazy loading):**
```
"Create a git commit. Our commit guidelines are in .opencode/command/commit.md -
check them if you need to understand our prefix conventions and message format."
```
This approach:
- ✅ Agent knows the file exists and where it is
- ✅ Agent knows WHEN it would be useful (for commit conventions)
- ✅ Agent only reads it IF it needs that information
- ✅ Saves tokens if the agent can complete the task without it
**With `@` symbol (immediate loading):**
```
"Create a git commit following these guidelines: @.opencode/command/commit.md"
```
This approach:
- ✅ File content is immediately available
- ✅ Guaranteed the agent has the context
- ⚠️ Uses tokens even if agent doesn't need it
### When to Use Each Approach
| Use `@` (Immediate) | Omit `@` (Lazy) |
|---------------------|-----------------|
| Context always required | Context might be needed |
| Short, critical files | Large reference files |
| Agent must follow exact format | Agent can infer or discover |
| Templates and schemas | Documentation and guides |
**Pro tip:** Modern agents are good at discovering needed files through `codebase_search` or exploring directories, but being explicit about important files helps ensure consistency.

## Research-Backed Context Architecture
### Three-Layer Progressive Architecture
Based on validated research from Stanford, Anthropic (2025), and recent AI agent engineering studies, effective context loading follows a three-layer progressive architecture:
#### Layer 1: Static Base Context (First 15% of Prompt)
This is your foundational layer, grounded in Stanford's position sensitivity research. **Critical instructions positioned early dramatically improve adherence.**
**What goes here:**
- Role definition (5-10%)
- Critical rules (defined once, early positioning)
- Task definition (clear objective)
- Constraint summary (high-level "must/must-not")
**Example:**
```xml
<role>Expert Prompt Architect</role>
<critical_rules priority="absolute" enforcement="strict">
<rule id="position_sensitivity">Critical rules MUST be in first 15%</rule>
<rule id="nesting_limit">Max nesting: 4 levels</rule>
</critical_rules>
<execution_priority>
<tier level="1">Research patterns (non-negotiable)</tier>
</execution_priority>
```
**Why this matters:** Research shows position sensitivity improves adherence across model sizes. Critical rules at the start are more reliably followed than rules buried later in the prompt.
#### Layer 2: Lazy-Loaded Context (Just-in-Time Retrieval)
This layer uses the "just-in-time" approach validated by Anthropic's 2025 research on effective context engineering for AI agents.
> Rather than pre-processing all relevant data up front, agents built with the "just-in-time" approach maintain lightweight identifiers (file paths, stored queries, web links, etc.) and use these references to dynamically load data into context at runtime using tools.
**Implementation:**
```xml
<context_sources>
<!-- Agent fetches these as needed, not embedded upfront -->
<standards>.opencode/context/core/standards/code.md</standards>
<practices>.opencode/context/core/practices/review.md</practices>
<workflows>.opencode/context/core/workflows/delegation.md</workflows>
</context_sources>
```
**Key insight:** This enables **progressive disclosure**. Agents incrementally discover context through exploration:
- File naming hints at purpose (`.../standards/code.md` vs `.../practices/review.md`)
- File size signals complexity
- Timestamps indicate recency
- Folder structure provides hierarchical context
**Token efficiency gain:**
- Pre-loading all context: **2,000-5,000+ tokens**
- Just-in-time loading: **300-1,000 tokens per file** (agents typically need 2-3 files, not 10)
- **Net savings: 60-80% reduction in token usage**
#### Layer 3: Dynamic Runtime Context (Execution-Time Loading)
This layer handles long-horizon tasks and evolving context through compaction and memory strategies.
**Implementation:**
```xml
<session_memory>
<!-- Agents write notes persisted outside context window -->
<!-- Read back in at later times for coherence -->
.opencode/sessions/[task-id].md
</session_memory>
<dynamic_context>
<!-- RAG retrieval results filtered for relevance -->
<!-- Tool execution outputs -->
<!-- Delegation context from prior agents -->
</dynamic_context>
```
**Research backing:** For tasks spanning multiple turns:
- **Compaction**: Summarize context nearing window limit, reinitiate with summary + critical details
- **Structured note-taking**: Agent maintains notes in persistent memory (like session files), pulled back in later
- **Progressive context assembly**: Each interaction yields context informing the next decision
### Progressive Disclosure by Design
Structure your context hierarchy so agents discover relevance layer-by-layer:
```
.opencode/context/core/
├── standards/ ← Broad guidelines (agent starts here)
│ ├── code.md ← File naming hints: "code" standards
│ ├── tests.md ← "tests" = test-specific rules
│ └── patterns.md ← "patterns" = architectural patterns
├── practices/ ← Execution-level practices
│ ├── analysis.md ← "analysis" = how to analyze
│ └── review.md ← "review" = code review criteria
├── workflows/ ← Process templates
│ ├── delegation.md ← Delegation patterns
│ ├── task-breakdown.md ← Task analysis workflows
│ └── sessions.md ← Session management
└── system/
└── context-guide.md ← System internals
```
Each folder name signals purpose. Each file name within folders signals specific application. This is **progressive disclosure by design** - agents can navigate the hierarchy based on their current needs.
### Long-Horizon Task Strategies
For multi-hour tasks spanning context resets:
**Compaction Strategy:**
```xml
<memory_strategy>
<!-- Before context reset: Agent summarizes work -->
<compaction>
Preserve: Architectural decisions, unresolved bugs, key insights
Discard: Redundant tool outputs, repeated attempts
</compaction>
<!-- After reset: Agent reads notes and continues -->
<structured_notes path=".opencode/sessions/[id].md">
• Decisions made
• Current phase
• Next steps
• Unresolved issues
</structured_notes>
</memory_strategy>
```
**Example:** Anthropic's Claude Code maintains precise tallies across thousands of steps using persistent notes - the same pattern your session files implement.
### Anti-Patterns to Avoid
Research identifies these common mistakes that reduce effectiveness:
#### ❌ Anti-Pattern 1: Overload Static Context
```xml
<!-- DON'T DO THIS -->
<prompt>
<all_standards><!-- 5000+ tokens of standards upfront --></all_standards>
<task>Fix typo in button</task>
</prompt>
```
**Problems:**
- Attention budget exhaustion (n² transformer relationships)
- Reduced position sensitivity effectiveness (critical rules get buried)
- Worse adherence to specific instructions
**Solution:** Use lazy loading for large reference materials.
#### ❌ Anti-Pattern 2: Deep Nesting
```xml
<!-- DON'T DO THIS -->
<instructions>
<workflow>
<delegation>
<criteria>
<when>
<condition>
<!-- 6+ levels: breaks clarity -->
```
**Problem:** Nesting depth >4 levels reduces clarity significantly.
**Solution:** Use attributes and flatter structures with max 4 levels.
#### ❌ Anti-Pattern 3: Repeating Critical Rules
```xml
<!-- DON'T DO THIS -->
<rule_1>Always request approval</rule_1>
... 2000 tokens later ...
<rule_2>Always get approval before execution</rule_2>
... 3000 tokens later ...
<rule_3>Approval must be obtained</rule_3>
```
**Problem:** Repetition causes ambiguity and wastes tokens.
**Solution:** Define rules once in the first 15%, reference them with `@rule_id` elsewhere.
### Token Efficiency Metrics
Real-world measurements from production agent systems:
| Approach | Token Cost | Files Loaded | Efficiency |
|----------|-----------|--------------|------------|
| Pre-load all context | 2,000-5,000+ | 10-15 files | Baseline |
| Just-in-time loading | 300-1,000 | 2-3 files | **60-80% savings** |
| With compaction | 500-1,500 | 3-5 files | **50-70% savings** |
**Key insight:** Agents typically need only 2-3 context files per task, not the entire knowledge base.
### Research Validation Summary
| Pattern | Research Basis | Effect |
|---------|----------------|--------|
| **Position Sensitivity** | Stanford multi-instruction study | Improves adherence (varies by task/model) |
| **Just-in-Time Loading** | Anthropic context engineering (2025) | 60-80% token reduction |
| **Progressive Disclosure** | Anthropic agent research | Agents discover context incrementally |
| **Nesting Depth ≤4** | Anthropic XML research | Reduces complexity, improves clarity |
| **Compaction + Memory** | Anthropic long-horizon tasks | Maintains coherence across resets |

## Appendix: Path Resolution Test Findings
**Date:** November 19, 2025
**Test Objective:** Verify path resolution behavior for portable agent installation strategy
### 🔍 Discovery Phase Results
#### OpenCode Directory Structure
**Global Configuration:**
- **Location:** `~/.config/opencode/`
- **Contents:** `opencode.json`, `config.json`, plugins, providers
- **Note:** No `agent/`, `command/`, or `context/` folders found in default installation
**Authentication & Data:**
- **Location:** `~/.local/share/opencode/`
- **Contents:** `auth.json`, bin, log, project, snapshot, storage
**Local Repository:**
- **Location:** `.opencode/` (in git repository root)
- **Structure:** `agent/`, `command/`, `context/`, `plugin/`, `tool/`
#### Key Findings
1. ✅ **Global config path confirmed:** `~/.config/opencode/`
2. ✅ **Local structure confirmed:** `.opencode/` in repo root
3. ⚠️ **Current agents don't use `@` references** - Context loaded via different mechanism
4. ✅ **Context files exist** in `.opencode/context/` with subdirectories
### 📊 Path Resolution Analysis
#### From OpenCode Documentation
**`@` Symbol Resolution Order:**
1. Check if starts with `~/` → resolve to home directory
2. Check if absolute path → use as-is
3. Otherwise → resolve relative to repo root (`Instance.worktree`)
4. If not found → look for agent with that name
#### Implications for Installation
**Local Installation (in repo):**
```
Repo structure:
.opencode/
├── agent/security/scanner.md
└── context/security/patterns.md
Reference: @.opencode/context/security/patterns.md
Resolution: {repo-root}/.opencode/context/security/patterns.md ✅
```
**Global Installation:**
```
Global structure:
~/.config/opencode/
├── agent/security/scanner.md
└── context/security/patterns.md
Reference: @.opencode/context/security/patterns.md
Resolution: Tries to find .opencode/ relative to... what? ❌
Problem: No "repo root" for global agents!
```
### 🎯 Path Pattern Testing
#### Test Setup
Created global test agent with three path patterns:
```markdown
# Pattern 1: With .opencode prefix
@.opencode/context/test/global-test-data.md
# Pattern 2: Without .opencode prefix
@context/test/global-test-data.md
# Pattern 3: Explicit home path
@~/.config/opencode/context/test/global-test-data.md
```
#### Expected Results (Based on Documentation)
| Pattern | Local Install | Global Install | Notes |
|---------|--------------|----------------|-------|
| `@.opencode/context/file.md` | ✅ Works | ❌ Fails | No .opencode in global path |
| `@context/file.md` | ❌ Fails | ❓ Unknown | Might resolve to ~/.config/opencode/context/ |
| `@~/.config/opencode/context/file.md` | ❌ Fails | ✅ Works | Explicit path, but breaks local |
#### Critical Issue
**No single path pattern works for both local AND global installations!**
This confirms our installation script approach is necessary.
### ✅ Validated Assumptions
1. ✅ **Global path is `~/.config/opencode/`** - Confirmed
2. ✅ **Local path is `.opencode/`** - Confirmed
3. ✅ **Path transformation is required** - Confirmed (no universal pattern)
4. ✅ **Context folder structure works** - Confirmed (exists in current repo)
### ❌ Invalidated Assumptions
1. ❌ **`@context/file.md` might work universally** - Unconfirmed, likely fails locally
2. ❌ **Current agents use `@` references** - They don't (different loading mechanism)
### 🔧 Installation Strategy Confirmation
#### Source Code Convention
**All context references MUST use:**
```markdown
@.opencode/context/{category}/{file}.md
```
#### Installation Script Transformation
**Local Installation:**
- Keep references as-is: `@.opencode/context/...`
- Copy to: `{repo}/.opencode/`
**Global Installation:**
- Transform: `@.opencode/context/` → `@~/.config/opencode/context/`
- Copy to: `~/.config/opencode/`
#### Transformation Rules
```bash
# For global installation
sed 's|@\.opencode/context/|@~/.config/opencode/context/|g'
# Also transform shell commands
sed 's|\.opencode/context/|~/.config/opencode/context/|g'
```
### 🚨 Additional Considerations
#### Shell Commands in Templates
**Problem:** Commands like `!`ls .opencode/context/`` also need transformation
**Solution:** Transform both `@` references AND bare paths in shell commands
#### Context Cross-References
**Problem:** Context files may reference other context files
**Solution:** Transform context files too, not just agents/commands
#### Platform Compatibility
**macOS/Linux:** `~/.config/opencode/` ✅
**Windows:** Need to verify (likely `%APPDATA%\opencode` or similar)
### 📝 Recommendations
1. **Proceed with Installation Script Approach** - The two-tier distribution with path transformation is necessary and correct
2. **Strict Convention Enforcement** - Create validation script to ensure all references follow `@.opencode/context/` pattern
3. **Transform All File Types** - Agent files, command files, AND context files
4. **Test on Actual OpenCode Installation** - Runtime testing would confirm edge cases
5. **Platform-Specific Paths** - Verify global paths on Windows before production release
