ENH-001-S2: Intent Detection System (2 pts)

[wtthornton]

User Story

As a developer, I want the system to detect my intent (build, fix, refactor, review) from my prompt, so that it can suggest the most appropriate workflow.

Acceptance Criteria

• ✅ Detects *build intent (keywords: build, create, add, implement, new, feature)
• ✅ Detects *fix intent (keywords: fix, bug, error, issue, broken, repair)
• ✅ Detects *refactor intent (keywords: refactor, modernize, improve, update)
• ✅ Detects *review intent (keywords: review, check, analyze, inspect, quality)
• ✅ Returns confidence score (0-100%)
• ✅ Triggers suggestion when confidence ≥60%
• ✅ Handles ambiguous cases (multiple high scores)

Tasks

• Task 2.1: Create IntentDetector class (3 hours)
• Task 2.2: Add context analysis (2 hours)
• Task 2.3: Write unit tests (3 hours)

Files to Create

• tapps_agents/workflow/intent_detector.py (150 lines)

Dependencies

• ENH-001-S4 (Configuration System) - ENH-001-S4: Configuration System (1 pt) #10
