What’s New

Interactive Standup Assistant (Epic #242)

Conversational standup creation via chat

Start a standup conversation with “let’s write a standup” or “/standup” and Piper will guide you through the process interactively:

• Preference gathering: Tell Piper your style preferences (concise, detailed, bullet points)
• Iterative refinement: Request changes until you’re happy with the result
• Version history: Previous versions saved if you want to compare
• Performance: Sub-500ms response times with P95 at 0.03ms

7-State Conversation Flow

The standup conversation uses a state machine with 7 distinct states:

State	Description
INITIATED	Conversation started, awaiting first user input
GATHERING_PREFERENCES	Collecting user preferences for standup style
GENERATING	Creating standup content from context
REFINING	User requesting changes to generated standup
FINALIZING	User approving final version
COMPLETE	Standup completed successfully
ABANDONED	User abandoned the conversation

Performance Monitoring (Issue #556)

Comprehensive structured logging for all standup operations:

• Turn response times with state transition tracking
• Generation success/failure metrics
• Retry and fallback tracking
• Conversation lifecycle events (completion, abandonment)
