No active slide entry found. Please set an active slide entr

Error message

No active slide entry found. Please set an active slide entry before using this tool.

What it means

Thrown by `resolveProjectFromEntry` (shared by most Slidev LM tools) when the entry is the sentinel `''` or `'$ACTIVE_SLIDE_ENTRY'` but no active entry has been set yet (`activeEntry.value` is falsy). These sentinels mean 'use whatever the user last chose'; if nothing was chosen, resolution cannot proceed.

Solutions

1. Call `slidev_chooseEntry` with a concrete entry path first to populate `activeEntry`, then retry the original tool.
2. Alternatively, pass an explicit `entrySlidePath` to the tool instead of relying on `$ACTIVE_SLIDE_ENTRY`.
3. Use `slidev_listEntries` to discover a valid entry path if you don't know one.

Example fix

// before: relying on the active sentinel before one is set
{ entrySlidePath: '$ACTIVE_SLIDE_ENTRY', slideNo: 1 } // throws [47]
// after: establish the active entry first
// step 1: slidev_chooseEntry { entrySlidePath: '/abs/slides.md' }
// step 2: slidev_getSlideContent { entrySlidePath: '$ACTIVE_SLIDE_ENTRY', slideNo: 1 }

// Before calling any tool with '$ACTIVE_SLIDE_ENTRY' or '', ensure one is set:
import { activeEntry } from './projects'
function hasActiveEntry(): boolean {
  return Boolean(activeEntry.value)
}
// if false, call slidev_chooseEntry first, or pass an explicit entrySlidePath.

function activeEntryIsSet(): boolean {
  return activeEntry.value != null && activeEntry.value !== ''
}

When it happens

Trigger: Any tool that calls `resolveProjectFromEntry` receives an empty string or `$ACTIVE_SLIDE_ENTRY` (e.g. the model omits a concrete path and relies on the default), but `activeEntry` was never populated because `slidev_chooseEntry` was not called successfully.

Common situations: The model calls `slidev_getSlideContent` / `slidev_findSlideNoByTitle` / etc. without first establishing which deck is active; the user opened a deck but never ran `chooseEntry`; the extension was reloaded and `activeEntry` reset to empty.
