tabctl

Original：🇺🇸 English

Translated

Manage and analyze Edge tabs and groups with tabctl. Use when asked to list, search, analyze stale or duplicate tabs, generate reports, or organize tabs. Prefer read-only commands and only run mutating actions with explicit targets and confirmation.

Tab Control

Use tabctl to inspect and analyze tabs safely, then perform targeted actions only when requested.

GraphQL API (preferred for agents)

Use

tabctl query

for field-selective reads and mutations in a single roundtrip. Use

tabctl schema

to discover available types and fields.

Read examples

bash

# Get only tabId and url for all windows
tabctl query '{ windows { windowId tabs { tabId url } } }'

# Paginated tabs (default limit 20)
tabctl query '{ tabs { items { tabId url title } total hasMore } }'

# Next page
tabctl query '{ tabs(offset: 20) { items { tabId url } total hasMore } }'

# Get tabs in a specific window
tabctl query '{ tabs(windowId: 123) { items { tabId title url } total } }'

# Get groups with tab counts
tabctl query '{ groups { groupId title tabCount } }'

# Get a single tab by ID
tabctl query '{ tab(id: 456) { tabId url title active groupTitle } }'

Mutation examples

bash

# Close tabs and get remaining tabs in one call
tabctl query 'mutation { closeTabs(tabIds: [123, 456], confirm: true) { txid closedTabs remainingTabs { tabId url } } }'

# Open tabs and get the new tab IDs
tabctl query 'mutation { openTabs(urls: ["https://example.com"], group: "Research") { tabs { tabId url } } }'

# Refresh tabs
tabctl query 'mutation { refreshTabs(tabIds: [123]) { refreshedTabs } }'

Introspection

bash

tabctl schema                    # Full SDL
tabctl query '{ __type(name: "Tab") { fields { name } } }'  # Discover Tab fields

Safety

Prefer read-only commands: list, analyze, inspect, report, query (without mutations).
Never run
```
archive --all
```
or
```
close --apply
```
in a normal session.
Only mutate explicit targets (
```
--tab
```
,
```
--group
```
,
```
--window
```
) and use
```
--confirm
```
for close.
Respect policy: protected tabs are excluded.
Use screenshots only when you need visual context.

Discover commands

Use
```
tabctl help
```
(or
```
tabctl help --json
```
) to discover commands and flags.
For specific commands, use
```
tabctl <command> --help
```
.

Common tasks (CLI)

List tabs in a window:

tabctl list --window <id|active|last-focused>

List ungrouped tabs:
```
tabctl list --ungrouped
```
List with pagination:
```
tabctl list --all --limit 10 --offset 0
```

Close tabs:

tabctl close --tab <id1> --tab <id2> --confirm

Refresh a tab:
```
tabctl refresh --tab <id>
```
Generate a report:
```
tabctl report --format md
```
(add scope flags as needed)

Get page metadata:

tabctl inspect --tab <id> --signal page-meta

Get page metadata after JS loads:

tabctl inspect --tab <id> --signal page-meta --wait-for settle

Extract links safely (absolute http(s) only):

tabctl inspect --tab <id> --selector '{"name":"links","selector":"a[href]","attr":"href-url","all":true}'

Capture visual context when needed:

tabctl screenshot --tab <id> --mode full

Undo most recent change:
```
tabctl undo --latest
```

Undo by txid:

tabctl undo <txid>

(from

tabctl history --json | jq -r '.[] | .txid'

)

Narrow scope

Use one or more of:

--window

--group

--group-id

--tab

--ungrouped

. If scope is unclear, ask for it before running mutating commands.

Troubleshooting

Check profile health:
```
tabctl doctor
```
Auto-repair broken profiles and resync extension files:
```
tabctl doctor --fix
```
Verify connection + runtime version sync:
```
tabctl ping --json
```
Read version state only from
```
ping
```
/
```
version
```
surfaces (not from
```
open
```
/
```
list
```
output payloads).
For local release-like sync checks during development, run a scoped command with
```
TABCTL_AUTO_SYNC_MODE=release-like
```
(example:
```
TABCTL_AUTO_SYNC_MODE=release-like tabctl list --all
```
).

Output flags

Use
```
--json
```
for JSON output (list/analyze/inspect/etc.).
```
--format
```
is only for
```
report
```
(e.g.,
```
tabctl report --format md
```
).

Wait modes for inspect/screenshot

Use

--wait-for

to control when inspection runs:

```
load
```
– wait for page load event (may miss JS-set titles)
```
dom
```
– wait for DOMContentLoaded
```
settle
```
– wait for URL and title to stabilize (500ms quiet period); use for JS-heavy pages or freshly opened tabs
```
none
```
– no waiting (default)

Example for newly opened tabs:

bash

tabctl open --url "https://example.com" --json
tabctl inspect --tab <new_tab_id> --wait-for settle --wait-timeout-ms 10000 --json
