Console Rendering Unification Plan

🎯 GOAL

Make history restoration look identical to real-time streaming by sharing the same rendering code.

🐛 CURRENT PROBLEM

FeatureReal-timeHistory
Prompt displayFull lengthTruncated 100 chars
Tool resultsFull content (short) or summarySummary only
Shell outputRich formatted blockPlain text summary
Diff displaySyntax highlightedNot rendered
Code filesconsole-ui.ts, console-event-handler.tsconsole-history.ts (inline)

✅ WHAT THE REFACTOR WOULD DO

1. Extract Shared Renderers

Create console-render-items.ts with functions like:

export function renderPromptLine(prompt, hasImages, imageNames)
export function renderToolUse(toolName, summary)
export function renderToolResult(output, toolContext)
export function renderAssistantText(text)
export function renderResponseGroup(kontext)

2. Replay Events Through Same Handler

History restoration would "replay" events through the same event handler that real-time uses:

// Instead of manual DOM creation:
for (const item of kontext.workingHistory) {
  handleStreamEvent({  // Same handler as real-time!
    type: item.type,
    tool: item.tool,
    input: item.input,
    output: item.output,
    text: item.text
  });
}

3. Store Richer Event Data

The kontext.workingHistory would need to store more detail:

  • Full tool result content (not just summary) for short outputs
  • Diff data for Edit tool results
  • Shell command + output for Bash results

4. Remove Inline Script Duplication

The ~500 lines of inline rendering in console-history.ts would be replaced with imports from shared modules, eliminating the duplication that causes divergence.

📊 EFFORT ESTIMATE

Create shared renderers~200 lines new
Refactor event handler~150 lines modified
Update history restoration~300 lines rewritten
Update kontext storage~50 lines modified
TestingManual + unit tests
TotalMedium effort (~2-3 hours)

🎁 BENEFITS

  • Visual consistency - History looks identical to real-time
  • Single source of truth - No more diverging code paths
  • Easier maintenance - Fix/improve in one place
  • Full prompts - See complete prompts in history
  • Rich results - Shell output, diffs, code blocks preserved

⚠️ CONSIDERATIONS

  • Storage size - Storing full results increases kontext size
  • Page load time - More data to render on refresh
  • Breaking change - Old kontexts won't have rich data

Recommendation: Start with the quick truncation fix, then do full refactor as a separate flow.
