Title is "Shelley", message input visible +- [ ] **Send button state** - Disabled when empty, enabled when text entered +- [ ] **Claude integration** - Messages send and receive responses (~2-3 seconds) +- [ ] **Prompt caching** - Check server logs for `cache_read_input_tokens` +- [ ] **Tool execution - bash** - Ask to run `echo hello`, verify tool output +- [ ] **Tool execution - think** - Send `think: analyzing...`, verify think tool appears +- [ ] **Tool execution - patch** - Send `patch: test.txt`, verify patch tool appears +- [ ] **Conversation persistence** - Multiple messages in same conversation work +- [ ] **Enter key sends** - Press Enter in textarea to send message +- [ ] **Model selector** - Shows available models in UI +- [ ] **Working directory** - Shows current directory path +- [ ] **Accessibility labels** - Input has `aria-label="Message input"`, button has `aria-label="Send message"` + +### Known Issues (Need Fixing/Re-checking) + +- [ ] **Empty message bug (CRITICAL)** - Rapid sequential messages cause 400 errors + - Test: Send 5+ messages quickly in succession + - Expected: All should succeed + - Actual: API returns `messages.N: all messages must have non-empty content` + +- [ ] **Cancellation state after reload** - Cancelled operations don't show "cancelled" text + - Test: Start `bash: sleep 100`, cancel it, reload page + - Expected: Should show "cancelled" or "[Operation cancelled]" + - Actual: Shows tool with `x` but no cancelled text + +- [ ] **Thinking indicator stuck on error** - Indicator doesn't hide when LLM fails + - Test: Trigger an LLM error (e.g., via rapid messages) + - Expected: Indicator should hide, error should display + - Actual: "Agent working..." stays visible indefinitely + +- [ ] **Menu button outside viewport** - Hamburger menu not clickable on mobile + - Test: On mobile viewport, try clicking menu button + - Expected: Menu should open + - Actual: Button reported as "outside of the viewport" + +- [ ] **Programmatic input filling** - Direct `.value` assignment doesn't enable send button + - Test: Use browser automation to set input value + - Expected: Send button should enable + - Actual: Button stays disabled (need to use native setter method) + +## Screenshots to Capture + +When testing, capture these screenshots for the report: + +1. `initial-load.png` -

Go Template Project

+ +
+

+ This is a starter template for building Go web applications on exe.dev. Customize this page and the code to create your own service. +

+

+ This VM has a persistent disk, sudo, HTTPS, and SSH all wired up. +

+
+ +
+

What next?

+
+
+

Customize this template

+

Edit the code to build your application.

+
    +
  • Source code is in ~
    • +
  • Edit via SSH or open in VS Code
    • +
  • Chat with our coding agent, Shelley
    • +
  • sudo systemctl restart srv to pick up changes
    • +
+
+
+

What's included

+

This template provides the essentials.

+
    +
  • HTTP server with routing and templates
    • +
  • SQLite database with migrations
    • +
  • Authentication via exe.dev headers
    • +
  • Systemd service configuration
    • +
+
+
+
+ +
{{.Hostname}}
+ + + +
+ + + + {{if .Headers}} +
+
+

HTTP headers from exe.dev

+
+

exe.dev adds extra headers to HTTP requests so that:

+
    +
  • you don't have to build auth
    • +
  • you know where the request came from
    • +
+

These are all the HTTP headers we received from exe.dev for this request.

+

The X-ExeDev-* and X-Forwarded-* headers are added by exe.dev.

+
+
+
+
+

+
