Add the Enhance Prompt feature to the VS Code extension, matching the
legacy extension's behaviour. A ✨ sparkle button in the chat input
toolbar rewrites the user's draft prompt using an LLM.
CLI:
- POST /enhance-prompt endpoint using LLM.stream with small model
- System prompt as agent.prompt for caching; user text as user message
- clean() strips code fences and surrounding quotes from LLM output
Extension:
- KiloProvider handler using SDK client.enhancePrompt.enhance()
- Shows VS Code error notification on failure
- WandSparkles icon from lucide-solid via @kilocode/kilo-ui
- Spin animation while enhancement is in flight
- Empty-input click shows feature description (all 16 i18n locales)
- Ctrl+Z / ⌘Z undo restores original draft
- Guard checks isBusy/isDisabled/enhancing matching canEnhance()
Tests:
- 11 unit tests for clean() in enhance-prompt.test.ts
Migration plan:
- Removed feature row (parity achieved)
- Deleted prompt-improvement.md spec doc
Replace the flat issue list in the migration plan with 37 detailed doc
files, one per issue, grouped into ui-polish/, features/, migration/,
error-handling/, performance/, infrastructure/, and cli-side/ directories.
Each doc describes the problem, what remains to be done, and implementation
notes — readable without opening the GitHub issue. The migration plan tables
now link to these docs instead of bare issue references.
