muse.ai DOM Page Structure Reference
Generated: 2026-10-04 via live CDP inspection (opm browser, warp-opm netns, CDP 9440) Purpose: Reference for future automation development. All selectors verified against live DOM.
1. Page States / Modes
The muse.ai SPA has distinct DOM states. Detect state before acting — selectors valid in one state are absent in another.
1.1 Main Chat
| Property | Value |
|---|---|
| URL | https://muse.ai/ |
| Title | Chat — <agent-name> (e.g., Chat — operator-main) |
Switcher [data-testid="hatch-chat-switcher-trigger"] |
✅ Present |
Compose [data-testid="hatch-chat-compose"] |
❌ Absent (panel closed) |
Panel content [data-testid="hatch-side-chats-panel-content"] |
❌ Absent (panel closed) |
Panel shell [data-testid="hatch-side-chats-panel-shell"] |
✅ Present (empty/collapsed) |
Message input [aria-label="Message"] |
✅ Present, visible |
Detection:
// Reliable main-chat detection
const isMainChat =
window.location.href === 'https://muse.ai/' &&
document.title.startsWith('Chat —') &&
!!document.querySelector('[data-testid="hatch-chat-switcher-trigger"]');
1.2 Panel Open (Chat Navigation Panel Visible)
Reached by clicking the switcher on main chat. This is the required precondition for sidechat creation.
| Property | Value |
|---|---|
| URL | https://muse.ai/ (unchanged) |
| Title | Chat — <agent-name> (unchanged) |
| Switcher | ✅ Present |
Compose [data-testid="hatch-chat-compose"] |
✅ Present and visible |
| Panel content | ✅ Present |
Thread rows [data-testid="hatch-thread-row"] |
✅ Present (26 rows observed) |
Detection:
// Panel is open and ready for sidechat creation
const isPanelOpen =
!!document.querySelector('[data-testid="hatch-side-chats-panel-content"]') &&
!!document.querySelector('[data-testid="hatch-chat-compose"]');
// Verify compose button is actually clickable
const composeBtn = document.querySelector('[data-testid="hatch-chat-compose"]');
const isClickable = composeBtn && composeBtn.getBoundingClientRect().width > 0;
Reliable open sequence:
// 1. Ensure on main chat (Ctrl+J via CDP Input.dispatchKeyEvent)
// 2. Check if panel already open
if (!document.querySelector('[data-testid="hatch-chat-compose"]')) {
// 3. Click switcher to open panel
document.querySelector('[data-testid="hatch-chat-switcher-trigger"]').click();
// 4. Wait 2s, re-check for compose button
}
1.3 /thread/new (Fresh Sidechat / Poisoned State)
This is the "poisoned" state. After creating a sidechat, the browser lands here with a stripped DOM that lacks the switcher and compose button. The next sidechat create will fail unless you navigate back to main first.
| Property | Value |
|---|---|
| URL | https://muse.ai/thread/new |
| Title | Muse (just "Muse", not "Chat — ...") |
| Switcher | ❌ Absent |
| Compose | ❌ Absent |
| Panel shell | ✅ Present but stripped (no panel-content) |
| Message input | ✅ Present |
| Button count | ~45 (vs ~21 on partially-loaded states) |
Detection:
const isThreadNew =
window.location.href.includes('/thread/new') ||
(document.title === 'Muse' &&
!document.querySelector('[data-testid="hatch-chat-switcher-trigger"]'));
Recovery: Send Ctrl+J via CDP to return to main chat, then open panel via switcher click.
Distinct testid set (no chat-switcher testids, dock-rail based):
hatch-dock-rail, hatch-dock-rail-divider, hatch-nav-chat,
hatch-dock-chat-notification-badge, hatch-nav-search,
hatch-nav-system-item-*, app-download-dock-mark, hatch-dock-more,
hatch-side-chats-open-drag-handle, hatch-side-chats-panel-shell,
hatch-chat-nav-fade, hatch-chat-leading-controls,
hatch-status-panel-sliding-surface, hatch-composer-placeholder-overlay,
hatch-browser-task-banner-host
1.4 Sidechat Thread (/thread/<uuid>)
A real sidechat with a UUID. DOM structure is similar to main chat (switcher present, panel available). Thread rows in the panel show the sidechat title.
Note: After sending the first message in a /thread/new chat, the URL transitions to /thread/<uuid>. Poll window.location.href after send to capture the real thread ID.
1.5 Landing Page (Not Logged In)
| Property | Value |
|---|---|
| Title | muse.ai (just the domain) |
| Indicators | Body contains "Log in" button, no chat UI |
Detection:
const isLanding = document.title === 'muse.ai';
// or
const isLoggedOut = document.body.innerText.includes('Log in') &&
!document.querySelector('[data-testid="hatch-chat-switcher-trigger"]');
1.6 State Summary Table
| State | URL | Title | Switcher | Compose | Panel Content |
|---|---|---|---|---|---|
| Main chat | muse.ai/ |
Chat — ... |
✅ | ❌ | ❌ |
| Panel open | muse.ai/ |
Chat — ... |
✅ | ✅ | ✅ |
/thread/new |
muse.ai/thread/new |
Muse |
❌ | ❌ | ❌ |
/thread/<uuid> |
muse.ai/thread/<uuid> |
Chat — ... |
✅ | ❌ | ❌ |
| Landing | muse.ai/ |

2. Key Selectors
2.1 Chat Switcher (Panel Toggle)
document.querySelector('[data-testid="hatch-chat-switcher-trigger"]')
| Attribute | Value |
|---|---|
| Tag | BUTTON |
data-testid |
hatch-chat-switcher-trigger |
| Inner text | Chats\nOpen chat and side chats (or Chats\nUnread chats\nOpen chat and side chats when unreads exist) |
aria-expanded |
Not used (always null) |
| Class (partial) | bg-fill-blur-thick shadow-blur-elevation-01 text-body-medium |
Parent chain (3-4 levels):
BUTTON[data-testid="hatch-chat-switcher-trigger"]
└── DIV[data-testid="hatch-chat-leading-controls"] (cls: pointer-events-auto absolute start-3)
└── DIV (cls: pointer-events-none absolute inset-x-0)
└── DIV (cls: absolute inset-0 overflow-hidden)
└── DIV (cls: relative flex min-h-0)
Visibility: Present on main chat and /thread/<uuid>. Absent on /thread/new and landing page.
Note: The old detection document.body.innerText.includes('Side chats') is invalid — it matches the switcher's "Open chat and side chats" text and DM content mentioning "Side chats". Use the exact header check or hatch-side-chats-panel-content presence instead.
2.2 Compose Button (New Side Chat +)
document.querySelector('[data-testid="hatch-chat-compose"]')
| Attribute | Value |
|---|---|
| Tag | BUTTON |
data-testid |
hatch-chat-compose |
aria-label |
New side chat |
title |
New side chat |
| Inner text | (empty — SVG icon only) |
| Class (partial) | inline-flex shrink-0 cursor-pointer |
Parent chain:
BUTTON[data-testid="hatch-chat-compose"]
└── SPAN (cls: contents)
└── DIV (cls: group/nav-section flex w-full)
└── SECTION (cls: flex flex-col)
└── DIV (cls: flex flex-col relative)
Visibility conditions:
- ✅ Present and visible only when panel is open
- ❌ Absent when panel is closed (even on main chat)
- ❌ Absent on
/thread/new(stripped DOM) - ❌ Absent on landing page
Critical: This button contains only an SVG icon. Do NOT search by text "+" — it will never match.
2.3 Sidechat Panel Shell
document.querySelector('[data-testid="hatch-side-chats-panel-shell"]')
Container for the entire chat navigation panel. Present in most states but may be empty/collapsed.
Children when panel is open:
hatch-side-chats-panel-sliding-surface
hatch-side-chats-panel-content
hatch-chat-search-toolbar
hatch-chat-search-field
hatch-side-chats-options
hatch-thread-row (× N)
hatch-chat-compose
hatch-side-chat-unread-indicator
2.4 Sidechat Panel Content
document.querySelector('[data-testid="hatch-side-chats-panel-content"]')
This is the reliable "panel is open" indicator. When present, the compose button should also be present.
2.5 Thread Rows (Chat List Items)
document.querySelectorAll('[data-testid="hatch-thread-row"]')
| Attribute | Value |
|---|---|
| Tag | DIV |
data-testid |
hatch-thread-row |
role |
button |
tabindex |
0 |
| Active row | aria-current="page" |
| Class (partial) | group/nav-row relative flex h-9 w-full shrink-0 items-center |
Not links — they are div[role="button"] with click handlers. No href. To navigate, click the row.
Text format: <title>\n<unread-indicator>\n<timestamp> (e.g., "Main chat\n\njust now")
Exact header check (reliable "Side chats" panel header detection):
// Find leaf element with exact text "Side chats"
const header = [...document.querySelectorAll('*')].find(e =>
e.children.length === 0 && (e.innerText || '').trim() === 'Side chats'
);
// Returns SPAN element when panel is open, null otherwise
2.6 Message Input (Composer)
document.querySelector('[aria-label="Message"]')
| Attribute | Value |
|---|---|
| Tag | TEXTAREA |
aria-label |
Message |
| Class (partial) | text-text-primary block max-h-48 |
Parent chain:
TEXTAREA[aria-label="Message"]
└── DIV (cls: relative flex min-h-8)
└── DIV (cls: flex shrink-0 flex-col)
└── DIV (cls: backdrop-blur-elevation-01 bg-fill-blur-thick shadow-blur-elevation-01)
2.7 "Main Chat" Navigation Button
To navigate to main chat from a sidechat, find the button with exact text "Main chat":
const mainBtn = [...document.querySelectorAll('button, [role="button"]')]
.find(e => (e.innerText || '').trim() === 'Main chat');
Must use exact match (=== 'Main chat'), not substring — thread rows may contain "Main chat" as part of longer text.
Alternative: Ctrl+J via CDP Input.dispatchKeyEvent (proven reliable for main-chat navigation):
// Via CDP websocket:
{"id": 30, "method": "Input.dispatchKeyEvent",
"params": {"type": "keyDown", "key": "j", "code": "KeyJ", "ctrlKey": True, "modifiers": 2}}
{"id": 31, "method": "Input.dispatchKeyEvent",
"params": {"type": "keyUp", "key": "j", "code": "KeyJ", "ctrlKey": True, "modifiers": 2}}
3. Approval / Permission Dialogs
3.1 How check_approvals Works
Location: /home/super/Projects/NetVM/bin/muse-chat-api.py, check_approvals(ws)
Detection logic:
- Scans
document.body.innerTextfor"Allow"+"to share"pattern - Finds elements containing both strings with text length < 500 chars
- Fallback: looks for buttons with text containing
allow/deny/block(if ≥2 found and no dialogs yet)
Critical filter (added 2026-10-04 to fix false positives):
# Only block for IP-based permission dialogs.
# Dialogs without IPs are likely false positives (chat content, UI text).
ips = re.findall(r'\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b', dialog_text)
if not ips:
continue # Skip — don't block
Trusted IPs (auto-approve "Allow"):
TRUSTED_IPS = {
"34.139.37.135", # VM (gateway)
"100.123.153.75", # bl (main compute)
"100.81.31.9", # VM tailnet
}
Auto-approve action: Clicks button with text "allow once" or exact "allow".
Exit code 2 with APPROVAL_NEEDED if untrusted IP dialog is found.
3.2 Dialog Selectors
No [role="dialog"] or [role="alertdialog"] elements were observed in the current DOM state. Permission dialogs appear as overlay elements when triggered (e.g., by download attempts, screen sharing requests).
Patterns to watch for:
// Dialog containers (when present)
'[role="dialog"]'
'[role="alertdialog"]'
'[data-testid*="dialog"]'
'[data-testid*="approval"]'
'[data-testid*="permission"]'
// Permission buttons (when dialog is active)
'button' // with text: /allow|deny|block/i
Known false positive: Task/checklist buttons in chat content may contain "Confirm" in their text (e.g., "Confirm 03:45 heartbeat in main thread"). The IP filter prevents these from blocking automation.
3.3 React DOM Selectors
Per AGENTS.md (2026-10-03): "The Muse platform is a React app. DOM selectors for dialogs exist identically in headful and headless environments." The check_approvals selectors work in both.
4. Overlays and Interaction Blockers
4.1 Observed Overlays
One fixed-position overlay with z-index: 26 was observed:
{
tag: "DIV",
id: null,
testid: null,
role: null,
z: "26",
cls: "absolute start-0 top-0"
}
4.2 Potential Blockers
| Element | Impact |
|---|---|
| Permission dialogs | Block sends until approved/dismissed |
hatch-browser-task-banner-host |
Browser task notification banner |
hatch-composer-placeholder-overlay |
Composer placeholder (not a blocker) |
hatch-status-panel-sliding-surface |
Status panel (may overlay content) |
Detection:
const blockers = [...document.querySelectorAll('*')].filter(e => {
const cs = getComputedStyle(e);
const r = e.getBoundingClientRect();
return (cs.position === 'fixed' || cs.position === 'absolute') &&
r.width > 100 && r.height > 100 &&
parseInt(cs.zIndex || '0') > 10;
});
5. URL Patterns
| URL Pattern | Meaning | DOM State |
|---|---|---|
https://muse.ai/ |
Main chat | Full DOM, switcher present |
https://muse.ai/thread/new |
New/unsent sidechat | Stripped DOM, no switcher/compose |
https://muse.ai/thread/<uuid> |
Existing sidechat | Full DOM, switcher present |
UUID format: Standard UUID v4 (e.g., 550e8400-e29b-41d4-a716-446655440000).
Navigation notes:
- After
sidechat create, URL goes to/thread/new(placeholder) - After first message send, URL transitions to
/thread/<uuid>(real ID) - Poll
window.location.hrefafter send to capture the real thread ID /thread/newpoisons subsequent creates — always navigate to main first

7. Reliable Automation Sequences
7.1 Sidechat Creation (Robust)
# 1. Navigate to main chat (recover from any state)
send_ctrl_j() # CDP Input.dispatchKeyEvent
time.sleep(3)
# 2. Verify we're on main chat
assert window.location.href == 'https://muse.ai/'
assert document.querySelector('[data-testid="hatch-chat-switcher-trigger"]')
# 3. Open panel if compose button not present
if not document.querySelector('[data-testid="hatch-chat-compose"]'):
document.querySelector('[data-testid="hatch-chat-switcher-trigger"]').click()
time.sleep(2)
# 4. Verify compose button is present AND visible
btn = document.querySelector('[data-testid="hatch-chat-compose"]')
assert btn and btn.getBoundingClientRect().width > 0
# 5. Click to create
btn.click()
# 6. Poll for /thread/ URL (up to 15s)
# 7. Send message directly (browser is on the new sidechat)
# 8. Poll URL for /thread/<uuid> to capture real thread ID
