# New Features - December 2025

## Overview

Jiva has been enhanced with four major improvements:

1. **Conversation Condensing** - Automatic history management to prevent token overload
2. **Conversation Save/Restore** - Persistent conversation storage in `~/.jiva/conversations`
3. **Pretty Markdown Rendering** - Beautiful CLI output with terminal-optimized markdown
4. **Mission-Driven Completion** - Agent doesn't stop prematurely, completes tasks thoroughly

---

## 1. Conversation Condensing

### What It Does

Automatically manages conversation history to prevent:
- Token limit errors
- WAF (Web Application Firewall) 403 errors from large requests
- Performance degradation from huge conversation histories

### How It Works

**Automatic Trimming** (during chat):
- Keeps: System message + Developer message + last 20 messages
- Triggered: Every API call

**Intelligent Condensing** (when threshold reached):
- Threshold: 30 messages (configurable)
- Keeps: System + Developer messages + last 10 messages
- Middle section: Condensed into AI-generated summary
- Summary preserves:
  - Key decisions and actions taken
  - Important information discovered
  - Tools used and results
  - Unresolved issues or pending tasks

### Configuration

```typescript
const agent = new JivaAgent({
  orchestrator,
  mcpManager,
  workspace,
  conversationManager,
  condensingThreshold: 30, // Default: 30 messages
});
```

### Example

```
Original: 40 messages
After condensing: 13 messages (system + developer + summary + 10 recent)
```

The condensed conversation maintains context while dramatically reducing token usage.

---

## 2. Conversation Save/Restore

### What It Does

Automatically saves and allows restoring of conversation histories, enabling:
- Pause and resume sessions
- Review past interactions
- Build on previous work
- Share conversation states (future feature)

### Storage Location

```
~/.jiva/conversations/
├── conv-2025-12-09T10-30-00-abc123.json
├── conv-2025-12-09T11-15-30-def456.json
└── conv-2025-12-09T12-45-15-ghi789.json
```

### Auto-Save

**Enabled by default**, saves conversations:
- After each user interaction (in chat mode)
- When agent cleanup is called
- Minimum: 2+ messages to avoid saving empty conversations

### REPL Commands

#### Save Current Conversation
```
You: save
✓ Conversation saved: conv-2025-12-09T10-30-00-abc123

✓ Conversation loaded: conv-2025-12-09T12-45-15-ghi789
```

### Conversation Metadata

Each saved conversation includes:
- **ID**: Unique identifier with timestamp
- **Created**: When conversation started
- **Updated**: Last modification time
- **Message Count**: Number of messages
- **Workspace**: Project directory (optional)
- **Summary**: AI-generated description (optional)

### Disabling Auto-Save

```typescript
const agent = new JivaAgent({
  orchestrator,
  mcpManager,
  workspace,
  conversationManager,
  autoSave: false, // Disable auto-save
});
```

---

## 3. Pretty Markdown Rendering

### What It Does

Transforms plain markdown text into beautifully formatted terminal output with:
- **Syntax highlighting** for code blocks
- **Styled headers** (bold, underlined)
- **Colored links** (blue, underlined)
- **Formatted lists** (bulleted and numbered)
- **Table rendering** (if markdown contains tables)
- **Text wrapping** (width: 100 characters)

### Before and After

**Before** (plain markdown):
```
# Installation

Run the following command:

npm install jiva

## Features

- **Fast**: Powered by gpt-oss-120b
- **Flexible**: Extensible with MCP servers
- **Smart**: Mission-driven completion
```

**After** (rendered):
```
INSTALLATION
═══════════

Run the following command:

  npm install jiva

FEATURES
────────

  • Fast: Powered by gpt-oss-120b
  • Flexible: Extensible with MCP servers
  • Smart: Mission-driven completion
```

(With colors: headers in yellow, code in cyan, etc.)

### How It Works

The markdown renderer:
1. Detects if response contains markdown formatting
2. If yes: Renders using `marked` + `marked-terminal`
3. If no: Outputs plain text as-is

### Detection Heuristics

Checks for:
- Headers (`# Header`)
- Bold/italic (`**bold**`, `*italic*`)
- Code blocks (` ```code``` `)
- Inline code (`` `code` ``)
- Lists (`-`, `*`, `1.`)
- Links (`[text](url)`)

### Usage

**Automatic in REPL:**
```
You: Explain how to use Git

Jiva:
# Git Basics

Git is a version control system...

## Common Commands

- `git init`: Initialize repository
- `git add`: Stage changes
...
```

**In `jiva run` command:**
```bash
npx jiva run "List the main features of Jiva"
```

Output is automatically rendered with markdown formatting.

### No Configuration Needed

Markdown rendering is automatic and always enabled. No setup required!

## 4. Mission-Driven Completion

### The Problem

Previously, the agent would sometimes stop prematurely:
- Encountering an error → stopping without trying alternatives
- Completing one part of multi-step task → not finishing the rest
- Getting stuck → giving up instead of asking for help

### The Solution

**Mission-Driven Completion Check** ensures the agent:
1. Reviews its work before ending
2. Continues if the task isn't fully complete
3. Tries alternative approaches when encountering errors
4. Only stops when:
   - Task is genuinely complete
   - User clarification is needed

### How It Works

**Before ending a task**, the agent checks:

```typescript
private isMissionComplete(response: string): boolean {
  // 1. Check response length (short responses are suspicious)
  if (response.length < 50) return false;

  // 2. Check for error indicators
  if (contains(['error', 'failed', 'unable to', 'cannot'])) {
    return false; // Task not complete with errors
  }

  // 3. Check for completion indicators
  if (contains(['completed successfully', 'finished', 'done'])) {
    return true;
  }

  return false; // Default: keep working
}
```

**If task appears incomplete:**
```
System: Before finishing, please review: Have you fully completed the
user's request? If there are any remaining steps, errors to resolve,
or aspects of the task left unfinished, please continue. Only respond
"TASK_COMPLETE" if everything is truly done.
```

The agent then:
- Re-evaluates its work
- Continues if needed
- Provides final confirmation when done

### System Prompt Enhancement

Added to developer message:
```
MISSION-DRIVEN COMPLETION:
- You are mission-driven: complete tasks thoroughly before stopping
- Before ending, review: Have I fully accomplished what was asked?
- If blocked or uncertain, explain the issue and ask for guidance
- Only stop when the task is complete OR you need user clarification
- If you encounter errors, try alternative approaches before giving up
```

### Example Scenarios

**Scenario 1: Error Recovery**

Before:
```
User: Create a new file at ~/Documents/test.txt
Agent: Error: Directory not found. [STOPS]
```

After:
```
User: Create a new file at ~/Documents/test.txt
Agent: Error: Directory not found.
Agent: Let me try creating the directory first...
Agent: Created directory ~/Documents
Agent: Created file test.txt successfully ✓
```

**Scenario 2: Multi-Step Task**

Before:
```
User: Find all TODO comments and list them in a file
Agent: Found 10 TODO comments [STOPS]
```

After:
```
User: Find all TODO comments and list them in a file
Agent: Found 10 TODO comments
Agent: Creating todos.md file...
Agent: Written 10 TODOs to todos.md ✓
```

**Scenario 3: Requesting Clarification**

```
User: Fix the bug
Agent: I found 3 potential bugs. Which one should I fix?
        1. Authentication timeout
        2. Memory leak in cache
        3. Race condition in file handler
```

The agent recognizes ambiguity and asks for clarification instead of guessing.

## Performance Impact

### Token Usage

**Before:**
- 50 message conversation = ~15,000 tokens per request
- Risk of hitting token limits
- Slow responses

**After:**
- 50 message conversation → condensed to 13 messages = ~4,000 tokens
- No token limit issues
- Fast responses

### Storage

Conversations are stored as JSON:
- Average: 50-100 KB per conversation
- 100 conversations ≈ 5-10 MB
- Negligible disk usage

### Rendering

Markdown rendering adds ~10-20ms per response:
- Imperceptible to users
- Worth it for improved readability

---

## Configuration Summary

```typescript
// Full configuration example
const conversationManager = new ConversationManager();
await conversationManager.initialize();

const agent = new JivaAgent({
  orchestrator,
  mcpManager,
  workspace,
  conversationManager,
  maxIterations: 10,              // Max agent loops
  temperature: 0.7,               // Model temperature
  autoSave: true,                 // Auto-save conversations
  condensingThreshold: 30,        // Condense after 30 messages
});
```

---

## Troubleshooting

### Conversation Not Saving

**Check:**
1. Directory exists: `ls ~/.jiva/conversations`
2. Permissions: `ls -la ~/.jiva`
3. Disk space: `df -h ~`

**Solution:**
```bash
mkdir -p ~/.jiva/conversations
chmod 755 ~/.jiva/conversations
```

### Markdown Not Rendering

**Check:**
1. Dependencies installed: `npm list marked marked-terminal`
2. Build completed: `npm run build`

**Solution:**
```bash
npm install marked marked-terminal @types/marked-terminal
npm run build
```

### Agent Still Stopping Prematurely

**Possible causes:**
1. `maxIterations` too low (increase to 15-20)
2. Task genuinely complete (false positive)
3. Model behavior (try different temperature)

**Solution:**
```bash
npx jiva chat --max-iterations 20 --temperature 0.8
```
