/cache-perplexity-session — Cache Perplexity Login for Council Commands

Capture Perplexity session state (cookies, localStorage, model preferences) from an already-authenticated browser session. Cached data is used by /council-refine and /export-to-council to skip fragile UI model-selector clicks.

Prerequisites: User must be logged into Perplexity in Chrome. Browser-bridge MCP server running with Chrome extension connected.

Input

$ARGUMENTS = Ignored (no arguments needed).

Workflow

Step 1: Navigate to Perplexity

• browser_navigate to https://www.perplexity.ai/
• Wait 3 seconds for full page load (auth state must be hydrated)

Step 2: Verify logged in

• Take a screenshot to confirm the user is logged in
• Look for indicators: user avatar, "New Thread" button, absence of "Sign in" button
• If NOT logged in, abort with message: "Please log into Perplexity in Chrome first, then re-run this command"

Step 3: Read session cookies

• Use browser_evaluate to read cookies:

  document.cookie
  

• Store the result as cookies string

Step 4: Read localStorage preferences

• Use browser_evaluate to read relevant localStorage keys:

  JSON.stringify(Object.fromEntries(
    Object.keys(localStorage)
      .filter(k => k.includes('session') || k.includes('model') || k.includes('user') || k.includes('auth') || k.includes('token') || k.includes('pplx') || k.includes('preference'))
      .map(k => [k, localStorage.getItem(k)])
  ))
  

• Parse the JSON result as localStorageData

Step 5: Detect current model and council state

• IMPORTANT: Council is NOT in the model selector dropdown. It's a separate "Model council" button/chip in the input toolbar area.
• Use browser_evaluate to check for the council button:

  (function() {
    const btn = [...document.querySelectorAll('button')].find(b => b.textContent.trim() === 'Model council');
    const modelBtn = document.querySelector('button[aria-label="Choose a model"]');
    const threeModels = document.querySelector('button[aria-label="3 models"]');
    return {
      councilButton: btn ? { found: true, classes: btn.className, active: btn.className.includes('bg-subtle') } : { found: false },
      modelSelector: modelBtn?.textContent?.trim() || 'not found',
      threeModelsDropdown: threeModels ? true : false
    };
  })()
  

• If council button found → currentModel = "council"
• If council button NOT found → currentModel = modelSelector text
