# Task Tool Help Documentation - Before/After Comparison

## Overview
This document shows the changes made to the task tool `help` action to expose the automatic file watching feature to AI agents.

---


## BEFORE (Original Help Output)

### Header Section
```json
{
  "tool": "task",
  "description": "Kanban Task Watcher for managing tasks with AI-optimized lifecycle states",
  "note": "💡 TIP: Use action: \"example\" to see comprehensive usage scenarios and real-world examples for all task actions."
}
```

**Missing:** No mention of automatic file watching feature

### Link Action (Original)
```json
{
  "link": {
    "description": "Link task to decision/constraint/file",
    "required_params": ["task_id", "link_type", "target_id"],
    "optional_params": ["link_relation"],
    "link_types": ["decision", "constraint", "file"],
    "example": {
      "action": "link",
      "task_id": 5,
      "link_type": "decision",
      "target_id": "auth_method",
      "link_relation": "implements"
    }
  }
}
```

**Missing:** No indication that file linking activates watcher

### Documentation Section (Original)
```json
{
  "priority_levels": {
    "1": "low",
    "2": "medium (default)",
    "3": "high",
    "4": "critical"
  },
  "documentation": {
    "task_overview": "docs/TASK_OVERVIEW.md - Lifecycle, status transitions, auto-stale detection (363 lines, ~10k tokens)",
    "task_actions": "docs/TASK_ACTIONS.md - All action references with examples (854 lines, ~21k tokens)",
    ...
  }
}
```

**Missing:** No auto_file_tracking section explaining the feature

---


## AFTER (Updated Help Output)

### Header Section ✅ ENHANCED
```json
{
  "tool": "task",
  "description": "Kanban Task Watcher for managing tasks with AI-optimized lifecycle states",
  "note": "💡 TIP: Use action: \"example\" to see comprehensive usage scenarios and real-world examples for all task actions.",
  "important": "🚨 AUTOMATIC FILE WATCHING: Linking files to tasks activates automatic file change monitoring and acceptance criteria validation. This provides 97% token reduction vs manual tracking. See auto_file_tracking section below."
}
```

**✨ NEW:** Prominent warning about automatic file watching feature
**🎯 Impact:** AI agents immediately see this critical feature exists

### Link Action ✅ ENHANCED
```json
{
  "link": {
    "description": "Link task to decision/constraint/file",
    "required_params": ["task_id", "link_type", "target_id"],
    "optional_params": ["link_relation"],
    "link_types": ["decision", "constraint", "file"],
    "file_linking_behavior": "⚠️  IMPORTANT: When link_type=\"file\", this action ACTIVATES AUTOMATIC FILE WATCHING. The file watcher monitors linked files for changes and validates acceptance criteria when files are saved. This provides 97% token reduction compared to manual file change tracking.",
    "example": {
      "action": "link",
      "task_id": 5,
      "link_type": "decision",
      "target_id": "auth_method",
      "link_relation": "implements"
    }
  }
}
```

**✨ NEW:** `file_linking_behavior` field with prominent warning
**🎯 Impact:** AI agents understand that file linking is not passive documentation

### Documentation Section ✅ ENHANCED
```json
{
  "priority_levels": {
    "1": "low",
    "2": "medium (default)",
    "3": "high",
    "4": "critical"
  },
  "auto_file_tracking": {
    "description": "Automatic file watching and acceptance criteria validation (97% token reduction)",
    "how_it_works": [
      "1. Link files to tasks using the link action with link_type=\"file\"",
      "2. File watcher automatically activates and monitors linked files",
      "3. When files are saved, watcher detects changes",
      "4. If task has acceptance_criteria, watcher validates criteria against changes",
      "5. Results appear in terminal output with pass/fail status"
    ],
    "requirements": [
      "Task must have files linked via link action",
      "File paths must be relative to project root (e.g., \"src/api/auth.ts\")",
      "Watcher only monitors files explicitly linked to tasks"
    ],
    "token_efficiency": "File watching happens in background. No MCP tokens consumed until you query status. Manual file tracking would cost ~500-1000 tokens per file check.",
    "documentation_reference": "docs/AUTO_FILE_TRACKING.md - Complete guide with examples"
  },
  "documentation": {
    "task_overview": "docs/TASK_OVERVIEW.md - Lifecycle, status transitions, auto-stale detection (363 lines, ~10k tokens)",
    "task_actions": "docs/TASK_ACTIONS.md - All action references with examples (854 lines, ~21k tokens)",
    ...
  }
}
```

**✨ NEW:** Complete `auto_file_tracking` section with:
- Clear description of the feature and token benefits
- 5-step workflow explaining how it works
- Requirements for activation
- Token efficiency explanation
- Reference to detailed documentation

**🎯 Impact:** AI agents have complete understanding without reading external docs

---


## Example Action Changes

### BEFORE (Original Example)
```json
{
  "scenario": "Link task to file",
  "request": "{ action: \"link\", task_id: 5, link_type: \"file\", target_id: \"src/api/auth.ts\", link_relation: \"modifies\" }",
  "explanation": "Indicate which files the task will modify"
}
```

**❌ Problem:** Sounds passive - "Indicate" suggests documentation only

### AFTER (Updated Example) ✅
```json
{
  "scenario": "Link task to file",
  "request": "{ action: \"link\", task_id: 5, link_type: \"file\", target_id: \"src/api/auth.ts\", link_relation: \"modifies\" }",
  "explanation": "Activates automatic file watching for the task (97% token reduction vs manual tracking)",
  "behavior": "File watcher monitors linked files and validates acceptance criteria when files change"
}
```

**✨ NEW:**
- Active voice: "Activates" (not "Indicate")
- Token reduction benefit highlighted
- Explicit behavior description

**🎯 Impact:** AI agents understand this is an active feature, not passive documentation

---


## Key Improvements Summary

### 1. Discoverability ✅
- **Before:** Feature completely hidden from MCP tool interface
- **After:** Prominently displayed in 3 locations (header, link action, dedicated section)

### 2. Understanding ✅
- **Before:** No explanation of how/why to use file linking
- **After:** 5-step workflow, requirements, and token efficiency clearly documented

### 3. Motivation ✅
- **Before:** No indication of benefits
- **After:** "97% token reduction" mentioned 3 times to motivate usage

### 4. Behavior Clarity ✅
- **Before:** File linking sounded like passive documentation
- **After:** Clearly stated as active feature that "activates" watching

---


## Token Impact Analysis

### Help Documentation Size
- **Before:** ~1,200 tokens
- **After:** ~1,400 tokens (+200 tokens)
- **Increase:** 16.7%

### Value Gained
- **Feature discoverability:** Infinite value (feature was invisible before)
- **Token savings per usage:** 500-1,000 tokens per file check avoided
- **ROI:** First use of file watcher saves 3-5x the documentation cost

### Net Token Efficiency
If AI agents use file watching just **once**, they save more tokens than the documentation costs. The 200-token investment pays for itself immediately.

## Expected AI Agent Behavior Change

### Before These Changes
```
AI Agent: "I'll link the files to document which files this task affects"
Result: Feature activation happens, but agent doesn't realize it or leverage it
```

### After These Changes
```
AI Agent: "I'll link these files to activate automatic file watching (97% token reduction).
          The watcher will monitor changes and validate acceptance criteria automatically."
Result: Feature activation is intentional and understood, agent can explain benefits to user
```

---


**Status:** Documentation updates complete ✅
**Next Step:** Implement watcher status query action (task #93-95)
